-# Helpers for defining environment variables for CircleCI.
-#
-# In CircleCI, each step runs in a new shell. The way to share ENV variables across steps is to
-# export them from `$BASH_ENV`, which is automatically sourced at the beginning of every step (for
-# the default `bash` shell).
-#
-# See also https://circleci.com/docs/2.0/env-vars/#using-bash_env-to-set-environment-variables.
-####################################################################################################
-
-# Set and print an environment variable.
-#
-# Use this function for setting environment variables that are public, i.e. it is OK for them to be
-# visible to anyone through the CI logs.
-#
-# Usage: `setPublicVar <name> <value>`
-function setPublicVar() {
-  setSecretVar $1 "$2";
-  echo "$1=$2";
-}
-
-# Set (without printing) an environment variable.
-#
-# Use this function for setting environment variables that are secret, i.e. should not be visible to
-# everyone through the CI logs.
-#
-# Usage: `setSecretVar <name> <value>`
-function setSecretVar() {
-  # WARNING: Secrets (e.g. passwords, access tokens) should NOT be printed.
-  # (Keep original shell options to restore at the end.)
-  local -r originalShellOptions=$(set +o);
-  set +x -eu -o pipefail;
-
-  echo "export $1=\"${2:-}\";" >> $BASH_ENV;
-
-  # Restore original shell options.
-  eval "$originalShellOptions";
-}
-
-
-# Create a function to set an environment variable, when called.
-#
-# Use this function for creating setter for public environment variables that require expensive or
-# time-consuming computaions and may not be needed. When needed, you can call this function to set
-# the environment variable (which will be available through `$BASH_ENV` from that point onwards).
-#
-# Arguments:
-# - `<name>`: The name of the environment variable. The generated setter function will be
-#   `setPublicVar_<name>`.
-# - `<code>`: The code to run to compute the value for the variable. Since this code should be
-#   executed lazily, it must be properly escaped. For example:
-#   ```sh
-#   # DO NOT do this:
-#   createPublicVarSetter MY_VAR "$(whoami)";  # `whoami` will be evaluated eagerly
-#
-#   # DO this isntead:
-#   createPublicVarSetter MY_VAR "\$(whoami)";  # `whoami` will NOT be evaluated eagerly
-#   ```
-#
-# Usage: `createPublicVarSetter <name> <code>`
-#
-# Example:
-# ```sh
-# createPublicVarSetter MY_VAR 'echo "FOO"';
-# echo $MY_VAR;  # Not defined
-#
-# setPublicVar_MY_VAR;
-# source $BASH_ENV;
-# echo $MY_VAR;  # FOO
-# ```
-function createPublicVarSetter() {
-  echo "setPublicVar_$1() { setPublicVar $1 \"$2\"; }" >> $BASH_ENV;

-# Yarn Vendoring
-We utilize Yarn's `yarn-path` configuration in a shared `.yarnrc` file to enforce
-everyone using the same version of Yarn.  Yarn checks the `.yarnrc` file to
-determine if yarn should delegate the command to a vendored version at the
-provided path.
-
-## How to update
-To update to the latest version of Yarn as our vendored version:
-- Run this command
-```sh
-yarn policies set-version latest
-```
-- Remove the previous version

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array and iteratees accept only
-     * one argument. The heuristic for whether a section qualifies for shortcut
-     * fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.

-     *
-     * The wrapper `String` methods are:

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could

-    // All japanese encodings are based on JIS X set of standards:
-    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
-    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
-    //              Has several variations in 1978, 1983, 1990 and 1997.
-    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
-    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
-    //              2 planes, first is superset of 0208, second - revised 0212.
-    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
-
-    // Byte encodings are:
-    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
-    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
-    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
-    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
-    //               0x00-0x7F       - lower part of 0201
-    //               0x8E, 0xA1-0xDF - upper part of 0201
-    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
-    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
-    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
-    //               Used as-is in ISO2022 family.
-    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
-    //                0201-1976 Roman, 0208-1978, 0208-1983.
-    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
-    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
-    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
-    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
-    //
-    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

-    //  * Big5-HKSCS (-2001, -2004, -2008). Hong Kong standard.

+
+## Breaking Changes
+
+### @angular/cli
+
+- The `ng` commands will no longer automatically detect and use `cnpm` as the package manager. As an alternative use the `.npmrc` file to ensure npm uses the cnpm registry.
+
+### @angular/build
+
+- - TypeScript versions older than 5.9 are no longer supported.
+- The `javascriptEnabled` option for Less is no longer supported. Projects relying on inline JavaScript within Less files will need to refactor their stylesheets to remove this dependency.
+
+### @schematics/angular

+
+## Breaking Changes
+
+### @angular/cli
+
+- Node.js v18 is no longer supported with Angular.
+
+  Before updating a project to Angular v20, the Node.js version must be
+  at least 20.11.1. For the full list of supported Node.js versions,
+  see https://angular.dev/reference/versions.
+
+- Node.js versions from 22.0 to 22.10 are no longer supported
+
+### @schematics/angular
+
+- `--server-routing` option has been removed from several schematics. Server routing will be used when using the application builder.
+
+### @angular-devkit/schematics
+
+- The `NodePackageLinkTask` has been removed without a replacement. Create a custom task if needed.
+
+  Note: This does not affect application developers.
+
+### @angular/build
+
+- TypeScript versions less than 5.8 are no longer supported.

+## Deprecations
+
+### @angular/build
+
+- The `baseHref` option under `i18n.locales` and `i18n.sourceLocale` in `angular.json` is deprecated in favor of `subPath`.
+
+  The `subPath` defines the URL segment for the locale, serving as both the HTML base HREF and the directory name for output. By default, if not specified, `subPath` will use the locale code.

+
+## Breaking Changes
+
+### @schematics/angular
+
+- The app-shell schematic is no longer compatible with Webpack-based builders.
+
+### @angular-devkit/build-angular
+
+- The `browserTarget` option has been removed from the DevServer and ExtractI18n builders. `buildTarget` is to be used instead.
+- Protractor is no longer supported.
+
+  Protractor was marked end-of-life in August 2023 (see https://protractortest.org/). Projects still relying on Protractor should consider migrating to another E2E testing framework, several support solid migration paths from Protractor.
+  - https://angular.dev/tools/cli/end-to-end
+  - https://blog.angular.dev/the-state-of-end-to-end-testing-with-angular-d175f751cb9c
+
+### @angular-devkit/core
+
+- The deprecated `fileBuffer` function is no longer available. Update your code to use `stringToFileBuffer` instead to maintain compatibility.
+
+  **Note:** that this change does not affect application developers.
+
+### @angular/build
+
+- The `@angular/localize/init` polyfill will no longer be added automatically to projects. To prevent runtime issues, ensure that this polyfill is manually included in the "polyfills" section of your "angular.json" file if your application relies on Angular localization features.
+

+
+# 18.0.0 (2024-05-22)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The `ng doc` command has been removed without a replacement. To perform searches, please visit www.angular.dev
+- Node.js support for versions <18.19.1 and <20.11.1 has been removed.
+
+### @angular-devkit/build-angular
+
+- By default, the index.html file is no longer emitted in the browser directory when using the application builder with SSR. Instead, an index.csr.html file is emitted. This change is implemented because in many cases server and cloud providers incorrectly treat the index.html file as a statically generated page. If you still require the old behavior, you can use the `index` option to specify the `output` file name.
+
+  ```json
+  "architect": {
+    "build": {
+      "builder": "@angular-devkit/build-angular:application",
+      "options": {
+        "outputPath": "dist/my-app",
+        "index": {
+          "input": "src/index.html",
+          "output": "index.html"
+        }
+      }
+    }
+  }
+  ```
+
+- The support for the legacy Sass build pipeline, previously accessible via `NG_BUILD_LEGACY_SASS` when utilizing webpack-based builders, has been removed.
+
+## Deprecations
+
+### @angular-devkit/schematics
+
+- `NodePackageLinkTask` in `@angular-devkit/schematics`. A custom task should be created instead.

+
+# 16.0.0 (2023-05-03)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The deprecated `defaultCollection` workspace option has been removed. Use `schematicCollections` instead.
+
+  Before
+
+  ```json
+  "defaultCollection": "@angular/material"
+  ```
+
+  After
+
+  ```json
+  "schematicCollections": ["@angular/material"]
+  ```
+
+- The deprecated `defaultProject` workspace option has been removed. The project to use will be determined from the current working directory.
+- Node.js v14 support has been removed
+
+  Node.js v14 is planned to be End-of-Life on 2023-04-30. Angular will stop supporting Node.js v14 in Angular v16.
+  Angular v16 will continue to officially support Node.js versions v16 and v18.
+
+### @schematics/angular
+
+- `ng g resolver` and `ng g guard` now generate a functional resolver or guard by default. It is still possible to generate a (deprecated) class-based resolver or guard by using `ng g resolver --no-functional` or `ng g guard --no-functional`.
+- The CLI no longer allows to generate `CanLoad` guards. Use `CanMatch` instead.
+
+###
+
+- - TypeScript 4.8 is no longer supported.
+
+### @angular-devkit/build-angular
+
+- Deprecated `outputPath` and `outputPaths` from the server and browser builder have been removed from the builder output. Use `outputs` instead.
+
+  Note: this change does not effect application developers.
+
+### @angular-devkit/core
+
+- Several changes to the `SchemaRegistry`.
+  - `compile` method now returns a `Promise`.
+  - Deprecated `flatten` has been removed without replacement.
+- - `ContentHasMutatedException`, `InvalidUpdateRecordException`, `UnimplementedException` and `MergeConflictException` API from `@angular-devkit/core` have been removed in favor of the API from `@angular-devkit/schematics`.
+  - `UnsupportedPlatformException` - A custom error exception should be created instead.
+
+### @angular-devkit/schematics
+
+- The depracated `UpdateBuffer` has been removed and `UpdateBuffer2`
+  is renamed to `UpdateBuffer`. With this change the related and
+  deprecated symbols `ContentCannotBeRemovedException` and `Chunk`
+  have also been removed.
+
+### @ngtools/webpack
+
+- NGCC integration has been removed and as a result Angular View Engine libraries will no longer work.
+
+### @schematics/angular

+
+# 15.0.0 (2022-11-16)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The Angular CLI no longer supports `16.10.x`, `16.11.x` and `16.12.x`. Current minimum versions of Node.js are `14.20.0`, `16.13.0` and `18.10.0`.
+- Node.js versions older than 14.20 are no longer supported.
+- The 'path' option in schematics schema no longer has a special meaning. Use 'workingDirectory' smart default provider should be used instead.
+
+### @schematics/angular
+
+- Removed unused `appDir` option from Universal and App-Shell schematic. This option can safely be removed if present since it no longer has effect.
+
+###
+
+- `analyticsSharing` option in the global angular configuration has been
+  removed without replacement. This option was used to configure the Angular CLI to access to your own users' CLI usage data.
+
+  If this option is used, it can be removed using `ng config --global cli.analyticsSharing undefined`.
+
+- analytics APIs have been removed without replacement from `@angular-devkit/core` and `@angular-devkit/architect`.
+
+### @angular-devkit/build-angular
+
+- TypeScript versions older than 4.8.2 are no longer supported.
+- The server builder `bundleDependencies` option has been removed. This option was used pre Ivy. Currently, using this option is unlikely to produce working server bundles.
+
+  The `externalDependencies` option can be used instead to exclude specific node_module packages from the final bundle.
+
+- - Deprecated support for tilde import has been removed. Please update the imports by removing the `~`.
+
+  Before
+
+  ```scss
+  @import '~font-awesome/scss/font-awesome';
+  ```
+
+  After
+
+  ```scss
+  @import 'font-awesome/scss/font-awesome';
+  ```
+
+  - By default the CLI will use Sass modern API, While not recommended, users can still opt to use legacy API by setting `NG_BUILD_LEGACY_SASS=1`.
+
+- Internally the Angular CLI now always set the TypeScript `target` to `ES2022` and `useDefineForClassFields` to `false` unless the target is set to `ES2022` or later in the TypeScript configuration. To control ECMA version and features use the Browerslist configuration.
+- `require.context` are no longer parsed. Webpack specific features are not supported nor guaranteed to work in the future.
+- Producing ES5 output is no longer possible. This was needed for Internet Explorer which is no longer supported. All browsers that Angular supports work with ES2015+
+- server builder `bundleDependencies` option now only accept a boolean value.
+- Deprecated support for Stylus has been removed. The Stylus package has never reached a stable version and its usage in the Angular CLI is minimal. It's recommended to migrate to another CSS preprocessor that the Angular CLI supports.
+
+### @angular-devkit/core
+
+- Workspace projects with missing `root` is now an error.
+
+### @ngtools/webpack
+
+- TypeScript versions older than 4.8.2 are no longer supported.

+
+# 14.0.0 (2022-06-02)
+
+## Breaking Changes
+
+### @angular/cli
+
+- Several changes to the `ng analytics` command syntax.
+  - `ng analytics project <setting>` has been replaced with `ng analytics <setting>`
+  - `ng analytics <setting>` has been replaced with `ng analytics <setting> --global`
+
+- Support for Node.js v12 has been removed as it will become EOL on 2022-04-30. Please use Node.js v14.15 or later.
+- Support for TypeScript 4.4 and 4.5 has been removed. Please update to TypeScript 4.6.
+- `--all` option from `ng update` has been removed without replacement. To update packages which don’t provide `ng update` capabilities in your workspace `package.json` use `npm update`, `yarn upgrade-interactive` or `yarn upgrade` instead.
+- Deprecated option `--prod` has been removed from all builders. `--configuration production`/`-c production` should be used instead if the default configuration of the builder is not configured to `production`.
+- `--configuration` cannot be used with `ng run`. Provide the configuration as part of the target. Ex: `ng run project:builder:configuration`.
+- Deprecated `ng x18n` and `ng i18n-extract` commands have been removed in favor of `ng extract-i18n`.
+- Several changes in the Angular CLI commands and arguments handling.
+  - `ng help` has been removed in favour of the `—-help` option.
+  - `ng —-version` has been removed in favour of `ng version` and `ng v`.
+  - Deprecated camel cased arguments are no longer supported. Ex. using `—-sourceMap` instead of `—-source-map` will result in an error.
+  - `ng update`, `—-migrate-only` option no longer accepts a string of migration name, instead use `—-migrate-only -—name <migration-name>`.
+  - `—-help json` help has been removed.
+
+### @angular-devkit/architect-cli
+
+- camel case arguments are no longer allowed.
+
+### @angular-devkit/schematics-cli
+
+- camel case arguments are no longer allowed.
+
+### @angular-devkit/build-angular
+
+- `browser` and `karma` builders `script` and `styles` options input files extensions are now validated.
+
+  Valid extensions for `scripts` are:
+  - `.js`
+  - `.cjs`
+  - `.mjs`
+  - `.jsx`
+  - `.cjsx`
+  - `.mjsx`
+
+  Valid extensions for `styles` are:
+  - `.css`
+  - `.less`
+  - `.sass`
+  - `.scss`
+  - `.styl`
+
+- We now issue a build time error since importing a CSS file as an ECMA module is non standard Webpack specific feature, which is not supported by the Angular CLI.
+
+  This feature was never truly supported by the Angular CLI, but has as such for visibility.
+
+- Reflect metadata polyfill is no longer automatically provided in JIT mode
+  Reflect metadata support is not required by Angular in JIT applications compiled by the CLI.
+  Applications built in AOT mode did not and will continue to not provide the polyfill.
+  For the majority of applications, the reflect metadata polyfill removal should have no effect.
+  However, if an application uses JIT mode and also uses the previously polyfilled reflect metadata JavaScript APIs, the polyfill will need to be manually added to the application after updating.
+  To replicate the previous behavior, the `core-js` package should be manually installed and the `import 'core-js/proposals/reflect-metadata';` statement should be added to the application's `polyfills.ts` file.
+- `NG_BUILD_CACHE` environment variable has been removed. `cli.cache` in the workspace configuration should be used instead.
+- The deprecated `showCircularDependencies` browser and server builder option has been removed. The recommended method to detect circular dependencies in project code is to use either a lint rule or other external tools.
+
+### @angular-devkit/core
+
+- `parseJson` and `ParseJsonOptions` APIs have been removed in favor of 3rd party JSON parsers such as `jsonc-parser`.
+- The below APIs have been removed without replacement. Users should leverage other Node.js or other APIs.
+  - `fs` namespace
+  - `clean`
+  - `mapObject`
+
+### @angular-devkit/schematics
+
+- Schematics `NodePackageInstallTask` will not execute package scripts by default
+  The `NodePackageInstallTask` will now use the package manager's `--ignore-scripts` option by default.
+  The `--ignore-scripts` option will prevent package scripts from executing automatically during an install.
+  If a schematic installs packages that need their `install`/`postinstall` scripts to be executed, the
+  `NodePackageInstallTask` now contains an `allowScripts` boolean option which can be enabled to provide the
+  previous behavior for that individual task. As with previous behavior, the `allowScripts` option will
+  prevent the individual task's usage of the `--ignore-scripts` option but will not override the package
+  manager's existing configuration.
+- Deprecated `analytics` property has been removed from `TypedSchematicContext` interface
+
+### @ngtools/webpack
+
+- `ivy` namespace has been removed from the public API.
+  - `ivy.AngularWebpackPlugin` -> `AngularWebpackPlugin`
+  - `ivy.AngularPluginOptions` -> `AngularPluginOptions`
+
+## Deprecations
+
+### @angular/cli
+
+- The `defaultCollection` workspace option has been deprecated in favor of `schematicCollections`.
+
+  Before
+
+  ```json
+  "defaultCollection": "@angular/material"
+  ```
+
+  After
+
+  ```json
+  "schematicCollections": ["@angular/material"]
+  ```
+
+- The `defaultProject` workspace option has been deprecated. The project to use will be determined from the current working directory.
+
+### @angular-devkit/core
+
+- - `ContentHasMutatedException`, `InvalidUpdateRecordException`, `UnimplementedException` and `MergeConflictException` symbol from `@angular-devkit/core` have been deprecated in favor of the symbol from `@angular-devkit/schematics`.
+  - `UnsupportedPlatformException` - A custom error exception should be created instead.

+
+# 13.0.0 (2021-11-03)
+
+## Breaking Changes
+
+### @angular/cli
+
+- We drop support for Node.js versions prior to `12.20`.
+
+### @schematics/angular
+
+- `classlist.js` and `web-animations-js` are removed from application polyfills and uninstalled from the package. These were only needed for compatibility with Internet Explorer, which is no longer needed now that Angular only supports evergreen browsers. See: https://angular.dev/reference/versions#browser-support.
+
+Add the following to the polyfills file for an app to re-add these packages:
+
+```typescript
+import 'classlist.js';
+import 'web-animations-js';
+```
+
+And then run:
+
+```sh
+npm install classlist.js web-animations-js --save
+```
+
+- We removed several deprecated `@schematics/angular` deprecated options.
+- `lintFix` have been removed from all schematics. `ng lint --fix` should be used instead.
+- `legacyBrowsers` have been removed from the `application` schematics since IE 11 is no longer supported.
+- `configuration` has been removed from the `web-worker` as it was unused.
+- `target` has been removed from the `service-worker` as it was unused.
+
+### @angular-devkit/build-angular
+
+- Support for `karma-coverage-instanbul-reporter` has been dropped in favor of the official karma coverage plugin `karma-coverage`.
+
+- Support for `node-sass` has been removed. `sass` will be used by default to compile SASS and SCSS files.
+
+- `NG_PERSISTENT_BUILD_CACHE` environment variable option no longer have effect. Configure `cli.cache` in the workspace configuration instead.
+
+```json
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
+  "version": 1,
+  "cli": {
+    "cache": {
+      "enabled": true,
+      "path": ".custom-cache-path",
+      "environment": "all"
+    }
+  }
+  ...
+}
+```
+
+- Calling `BuilderContext.scheduleBuilder()` with a builder from `@angular-devkit/build-angular` now requires passing the `target` property in the 3rd argument, like in the following example:
+
+  ```typescript
+  context.scheduleBuilder('@angular-devkit/build-angular:ng-packagr', options, {
+    target: context.target,
+  });
+  ```
+
+- The automatic inclusion of Angular-required ES2015 polyfills to support ES5 browsers has been removed. Previously when targeting ES5 within the application's TypeScript configuration or listing an ES5 requiring browser in the browserslist file, Angular-required polyfills were included in the built application. However, with Angular no longer supporting IE11, there are now no browsers officially supported by Angular that would require these polyfills. As a result, the automatic inclusion of these ES2015 polyfills has been removed. Any polyfills manually added to an application's code are not affected by this change.
+
+- With this change a number of deprecated dev-server builder options which proxied to the browser builder have been removed. These options should be configured in the browser builder instead.
+
+The removed options are:
+
+- `aot`
+- `sourceMap`
+- `deployUrl`
+- `baseHref`
+- `vendorChunk`
+- `commonChunk`
+- `optimization`
+- `progress`
+
+- With this change we removed several deprecated builder options
+- `extractCss` has been removed from the browser builder. CSS is now always extracted.
+- `servePathDefaultWarning` and `hmrWarning` have been removed from the dev-server builder. These options had no effect.
+
+- Deprecated `@angular-devkit/build-angular:tslint` builder has been removed. Use https://github.com/angular-eslint/angular-eslint instead.
+
+- Differential loading support has been removed. With Angular no longer supporting IE11, there are now no browsers officially supported by Angular that require ES5 code. As a result, differential loading's functionality for creating and conditionally loading ES5 and ES2015+ variants of an application is no longer required.
+
+- TypeScript versions prior to 4.4 are no longer supported.
+
+- The dev-server now uses WebSockets to communicate changes to the browser during HMR and live-reloaded. If during your development you are using a proxy you will need to enable proxying of WebSockets.
+
+- We remove inlining of Google fonts in WOFF format since IE 11 is no longer supported. Other supported browsers use WOFF2.
+
+### @angular-devkit/build-webpack
+
+- Support for `webpack-dev-server` version 3 has been removed. For more information about the migration please see: https://github.com/webpack/webpack-dev-server/blob/master/migration-v4.md
+
+Note: this change only affects users depending on `@angular-devkit/build-webpack` directly.
+
+### @angular-devkit/core
+
+- With this change we drop support for the deprecated behaviour to transform `id` in schemas. Use `$id` instead.
+
+Note: this only effects schematics and builders authors.
+
+- The deprecated JSON parser has been removed from public API. [jsonc-parser](https://www.npmjs.com/package/jsonc-parser) should be used instead.
+
+### @angular-devkit/schematics
+
+- `isAction` has been removed without replacement as it was unused.
+
+- With this change we remove the following deprecated APIs
+- `TslintFixTask`
+- `TslintFixTaskOptions`
+
+**Note:** this only effects schematics developers.
+
+### @ngtools/webpack
+
+- Deprecated `inlineStyleMimeType` option has been removed from `AngularWebpackPluginOptions`. Use `inlineStyleFileExtension` instead.
+
+- Applications directly using the `webpack-cli` and not the Angular CLI to build must set the environment variable `DISABLE_V8_COMPILE_CACHE=1`. The `@ngtools/webpack` package now uses dynamic imports to provide support for the ESM `@angular/compiler-cli` package. The `v8-compile-cache` package used by the `webpack-cli` does not currently support dynamic import expressions and will cause builds to fail if the environment variable is not specified. Applications using the Angular CLI are not affected by this limitation.
+
+## Deprecations
+
+###
+
+- `@angular-devkit/build-optimizer`
+
+It's functionality has been included in `@angular-devkit/build-angular` so this package is no longer needed by the CLI and we will stop publishing the package soon. It has been an experimental (never hit `1.0.0`) and internal (only used by Angular itself) package and should be not be used directly by others.
+
+### @angular-devkit/build-angular
+
+- `NG_BUILD_CACHE` environment variable option will be removed in the next major version. Configure `cli.cache` in the workspace configuration instead.
+

+    @schematics/angular: remove `stylus` from `style` options (<a href="https://github.com/angular/angular-cli/commit/fd729aca0e74c242797d4697786fbede06bc844b">fd729ac</a>)
+</h3>
+`styl` (Stylus) is no longer a supported value as `style` in `application`, `component`, `ng-new` schematics. Stylus is not actively maintained and only 0.3% of the Angular CLI users use it.
+
+(cherry picked from commit 0272fc55b67d1a3f986b996c8eb21aea31eedf51)

+<h3>
+    @angular-devkit/build-angular: change several builder options defaults (<a href="https://github.com/angular/angular-cli/commit/656f8d75a3368a5affd1c55145841123dafdb007">656f8d7</a>)
+</h3>
+A number of browser and server builder options have had their default values changed. The aim of these changes is to reduce the configuration complexity and support the new "production builds by default" initiative.
+
+**Browser builder**
+| Option | Previous default value | New default value |
+|----------------------------------------|---------------------------|-------------------|
+| optimization | false | true |
+| aot | false | true |
+| buildOptimizer | false | true |
+| sourceMap | true | false |
+| extractLicenses | false | true |
+| namedChunks | true | false |
+| vendorChunk | true | false |
+
+**Server builder**
+| Option | Previous default value | New default value |
+|---------------|------------------------|-------------------|
+| optimization | false | true |
+| sourceMap | true | false |
+
+(cherry picked from commit 0a74d0d28daf68510459ed73ef048c91bfcabbbc)

+<h3>
+    @angular-devkit/core: update schema validator (<a href="https://github.com/angular/angular-cli/commit/08753138d336fb870a66face70f5624ba64b4c69">0875313</a>)
+</h3>
+support for JSON Schema draft-04 and draft-06 is removed. If you have schemas using the `id` keyword replace them with `$id`. For an interim period we will auto rename any top level `id` keyword to `$id`.
+
+**NB**: This change only effects schematics and builders authors.
+
+<h3>
+    @angular-devkit/build-angular: upgrade to Webpack 5 throughout the build system (<a href="https://github.com/angular/angular-cli/commit/d883ce5d7e39de774fe90e4ccdbc9a84a600b7e8">d883ce5</a>)
+</h3>
+Webpack 5 lazy loaded file name changes
+Webpack 5 generates similar but differently named files for lazy loaded JavaScript files in development configurations (when the `namedChunks` option is enabled).
+For the majority of users this change should have no effect on the application and/or build process. Production builds should also not be affected as the `namedChunks` option is disabled by default in production configurations.
+However, if a project's post-build process makes assumptions as to the file names then adjustments may need to be made to account for the new naming paradigm.
+Such post-build processes could include custom file transformations after the build, integration into service-side frameworks, or deployment procedures.
+Example development file name change: `lazy-lazy-module.js` --> `src_app_lazy_lazy_module_ts.js`
+
+Webpack 5 now includes web worker support. However, the structure of the URL within the `Worker` constructor must be in a specific format that differs from the current requirement.
+Web worker usage should be updated as shown below (where `./app.worker` should be replaced with the actual worker name):
+Before: `new Worker('./app.worker', ...)`
+After: `new Worker(new URL('./app.worker', import.meta.url), ...)`
+
+<h3>
+    @ngtools/webpack: remove Webpack plugin for deprecated ViewEngine compiler (<a href="https://github.com/angular/angular-cli/commit/160102ae57d780dded6c9002faf07b601a866d3d">160102a</a>)
+</h3>
+Removal of View Engine support from application builds
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the View Engine Webpack plugin has been removed.
+The Ivy-based Webpack plugin is the default used within the Angular CLI.
+If using a custom standalone Webpack configuration, the removed `AngularCompilerPlugin` should be replaced with the Ivy-based `AngularWebpackPlugin`.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated i18n options from server and browser builder (<a href="https://github.com/angular/angular-cli/commit/5cf9a08dc7a1c84568d00df8f957d55b10ce0193">5cf9a08</a>)
+</h3>
+Removal of deprecated browser and server command options.
+- `i18nFile`,  use `locales` object in the project metadata instead.
+- `i18nFormat`, No longer needed as the format will be determined automatically.
+- `i18nLocale`, use `localize` option instead.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated i18nLocale and i18nFormat options from i18n-extract (<a href="https://github.com/angular/angular-cli/commit/eca5a01f6e8d1c3ad874d74c58e6ffbddab6a031">eca5a01</a>)
+</h3>
+Removal of deprecated `extract-i18n` command options
+The deprecated `i18nLocale` option has been removed and the `i18n.sourceLocale` within a project's configuration should be used instead.
+The deprecated `i18nFormat` option has been removed and the `format` option should be used instead.
+
+<h3>
+    @angular-devkit/build-angular: remove usage of deprecated View Engine compiler (<a href="https://github.com/angular/angular-cli/commit/677913fc389f0ffa20e3e1928d7244427c07ef35">677913f</a>)
+</h3>
+Removal of View Engine support from application builds
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, Ivy-based compilation will always be used when building an application.
+The default behavior for applications is to use the Ivy compiler when building and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and an Ivy-based build will be attempted. If the build fails,
+the application may need to be updated to become Ivy compatible.
+
+<h3>
+    @schematics/angular: remove `entryComponent` from `component` schematic (<a href="https://github.com/angular/angular-cli/commit/8582ddc35e153b8bc409d0505f29bc43e6cef455">8582ddc</a>)
+</h3>
+`entryComponent` option has been removed from the `component` schematic as this was intended to be used with the now no longer supported ViewEngine rendering engine.
+
+<h3>
+    @angular-devkit/build-angular: remove view engine app-shell generation (<a href="https://github.com/angular/angular-cli/commit/1c2aeeb46a23fd511c89f9c8800ac2a5ab0c2734">1c2aeeb</a>)
+</h3>
+App-shell builder now only supports generation using Ivy
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated View Engine support for i18n extraction (<a href="https://github.com/angular/angular-cli/commit/012700ace56d6d0e35d6798c5a19534ffa5a5a0e">012700a</a>)
+</h3>
+Removal of View Engine support from i18n extraction
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the `ng extract-i18n` command will now always use the Ivy compiler.
+The `--ivy` option has also been removed as Ivy-based extraction is always enabled.
+The default behavior for applications is to use the Ivy compiler for building/extraction and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and Ivy-based extraction will be attempted. If the extraction fails,
+the application may need to be updated to become Ivy compatible.
+
+<h3>
+    @angular/cli: confirm ng add action before installation (<a href="https://github.com/angular/angular-cli/commit/985dc1a4c71693ad78c35f5d6e95397f9753239e">985dc1a</a>)
+</h3>
+The `ng add` command will now ask the user to confirm the package and version prior to installing and executing an uninstalled package.
+This new behavior allows a user to abort the action if the version selected is not appropriate or if a typo occurred on the command line and an incorrect package would be installed.
+A `--skip-confirmation` option has been added to skip the prompt and directly install and execute the package. This option is useful in CI and non-TTY scenarios such as automated scripts.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated `lazyModules` option (<a href="https://github.com/angular/angular-cli/commit/8d669123236c49e7f6bee1a7171c002abe03df1a">8d66912</a>)
+</h3>
+Server and Browser builder `lazyModules` option has been removed without replacement.
+
+<h3>
+    @ngtools/webpack: drop support for string based lazy loading (<a href="https://github.com/angular/angular-cli/commit/0dc73276cafd42415dcaa6507ab221f1116273b5">0dc7327</a>)
+</h3>
+With this change we drop support for string based lazy loading `./lazy.module#LazyModule`  use dynamic imports instead.
+
+The following options which were used to support the above syntax were removed without replacement.
+
+- discoverLazyRoutes
+- additionalLazyModules
+- additionalLazyModuleResources
+- contextElementDependencyConstructor
+
+<h3>
+    @angular-devkit/build-angular: enable inlineCritical by default (<a href="https://github.com/angular/angular-cli/commit/aa3ea885ed69cfde0914abae547e15d6d499a908">aa3ea88</a>)
+</h3>
+Critical CSS inlining is now enabled by default. If you wish to turn this off set `inlineCritical` to `false`.
+
+See: https://angular.dev/reference/configs/workspace-config#optimization-configuration
+
+<h3>
+    @angular-devkit/build-angular: drop support for zone.js 0.10 (<a href="https://github.com/angular/angular-cli/commit/f309516bcdcee711fc5693b5f14d6fef1cfa5dba">f309516</a>)
+</h3>
+Minimum supported `zone.js` version is `0.11.4`
+
+<h3>
+    @angular-devkit/build-angular: drop support for ng-packagr version 11 (<a href="https://github.com/angular/angular-cli/commit/44e75be5b127545bf87e2d6d61370944f4d380a1">44e75be</a>)
+</h3>
+Minimum supported `ng-packagr` version is `12.0.0-next`
+
+<h3>
+    @angular-devkit/build-angular: drop support for karma version 5.2 (<a href="https://github.com/angular/angular-cli/commit/fa5cf53b644c96a50d09dce5f9e9ee401bf66053">fa5cf53</a>)
+</h3>
+Minimum supported `karma` version is `6.0.0`
+
+<h3>
+    set minimum Node.js version to 12.13 (<a href="https://github.com/angular/angular-cli/commit/d1f616930de4a8312e3441410098d9f248855d9d">d1f6169</a>)
+</h3>
+Node.js version 10 will become EOL on 2021-04-30.
+Angular CLI 12 will require Node.js 12.13+ or 14.15+. Node.js 12.13 and 14.15 are the first LTS releases for their respective majors.
+
+<h3>
+    @angular-devkit/build-angular: remove file-loader dependency (<a href="https://github.com/angular/angular-cli/commit/6732294ff34ca35698cec5a9ca91b664dd684289">6732294</a>)
+</h3>
+The unsupported/undocumented, Webpack specific functionality to `import`/`require()` a non-module file has been removed.
+
+Before
+
+```js

+    @schematics/angular: remove `stylus` from `style` options (<a href="https://github.com/angular/angular-cli/commit/fd729aca0e74c242797d4697786fbede06bc844b">fd729ac</a>)
+</h3>
+`styl` (Stylus) is no longer a supported value as `style` in `application`, `component`, `ng-new` schematics. Stylus is not actively maintained and only 0.3% of the Angular CLI users use it.
+
+(cherry picked from commit 0272fc55b67d1a3f986b996c8eb21aea31eedf51)
+
+<h3>
+    @angular-devkit/build-angular: change several builder options defaults (<a href="https://github.com/angular/angular-cli/commit/656f8d75a3368a5affd1c55145841123dafdb007">656f8d7</a>)
+</h3>
+A number of browser and server builder options have had their default values changed. The aim of these changes is to reduce the configuration complexity and support the new "production builds by default" initiative.
+
+**Browser builder**
+| Option | Previous default value | New default value |
+|----------------------------------------|---------------------------|-------------------|
+| optimization | false | true |
+| aot | false | true |
+| buildOptimizer | false | true |
+| sourceMap | true | false |
+| extractLicenses | false | true |
+| namedChunks | true | false |
+| vendorChunk | true | false |
+
+**Server builder**
+| Option | Previous default value | New default value |
+|---------------|------------------------|-------------------|
+| optimization | false | true |
+| sourceMap | true | false |
+
+(cherry picked from commit 0a74d0d28daf68510459ed73ef048c91bfcabbbc)

+</h3>
+Webpack 5 generates similar but differently named files for lazy loaded JavaScript files in development configurations (when the `namedChunks` option is enabled).
+For the majority of users this change should have no effect on the application and/or build process. Production builds should also not be affected as the `namedChunks` option is disabled by default in production configurations.
+However, if a project's post-build process makes assumptions as to the file names then adjustments may need to be made to account for the new naming paradigm.
+Such post-build processes could include custom file transformations after the build, integration into service-side frameworks, or deployment procedures.
+Example development file name change: `lazy-lazy-module.js` --> `src_app_lazy_lazy_module_ts.js`

+Webpack 5 now includes web worker support. However, the structure of the URL within the `Worker` constructor must be in a specific format that differs from the current requirement.
+Web worker usage should be updated as shown below (where `./app.worker` should be replaced with the actual worker name):
+
+Before:
+
+```
+new Worker('./app.worker', ...)
+```
+
+After:
+
+```
+new Worker(new URL('./app.worker', import.meta.url), ...)

+# Breaking Changes
+
+<h3>
+    @angular/cli: confirm ng add action before installation (<a href="https://github.com/angular/angular-cli/commit/985dc1a4c71693ad78c35f5d6e95397f9753239e">985dc1a</a>)
+</h3>
+The `ng add` command will now ask the user to confirm the package and version prior to installing and executing an uninstalled package.
+This new behavior allows a user to abort the action if the version selected is not appropriate or if a typo occurred on the command line and an incorrect package would be installed.
+A `--skip-confirmation` option has been added to skip the prompt and directly install and execute the package. This option is useful in CI and non-TTY scenarios such as automated scripts.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering a safe and welcoming environment, we as
+the Angular team pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity, gender expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Use welcoming and inclusive language
+* Respect each other
+* Provide and gracefully accept constructive criticism
+* Show empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* The use of sexualized language or imagery
+* Unwelcome sexual attention or advances
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Angular team are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Angular team have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, and to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies to all Angular communication channels - online or in person,
+and it also applies when an individual is representing the project or its community in
+public spaces. Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the Angular team at conduct@angular.io. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The Angular team
+will maintain confidentiality with regard to the reporter of an incident.
+Enforcement may result in an indefinite ban from all official Angular communication
+channels, or other actions as deemed appropriate by the Angular team.
+
+Angular maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+### Appeal
+
+If you are banned you may contest the decision. To do so email conduct@angular.io with the subject line "Repeal Ban for {{your name here}}" and body with the responses to the following:
+
+* Why do you believe you did not violate the Code of Conduct?
+* Were other factors involved in this situation the leadership team may have been unaware of?
+* Why do you wish to be a part of the Angular community?
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org), version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-## <a name="public-api"></a> Updating the Public API
-Our Public API is protected with TS API Guardian. This is a tool that keeps track of public API surface of our packages.
-
-To test if your change effect the public API you need to run the API guardian on that particular package.
-
-For example in case `@angular-devkit/core` package was modified you need to run:
-
-```bash
-yarn bazel test //goldens/public-api:angular_devkit_core_api
-```
-
-You can also test all packages by running:
-```bash
-yarn bazel test //goldens/public-api ...
-```
-
-If you modified the public API, the test will fail. To update the golden files you need to run:
-
-```bash
-yarn bazel run //goldens/public-api:angular_devkit_core_api.accept
-```
-
-**Note**: In some cases we use aliased symbols to create namespaces.
-
-Example:
-```javascript
-import * as foo from './foo';
-
-export { foo };
-```
-There are currently not supported by the API guardian.
-To overcome this limitation we created `_golden-api.ts` in certain packages.
+[stackoverflow]: https://stackoverflow.com/questions/tagged/angular-devkit
 
-When adding a new API, it might be the case that you need to add it to `_golden-api.ts`.

-|---|---|---|
+## Development Setup
 
-----
 
-## The Goal of Angular CLI
+### Prerequisites
 
-The Angular CLI creates, manages, builds and test your Angular projects. It's built on top of the
-Angular DevKit.
+- Install [Node.js] which includes [Node Package Manager][npm]
 
-## The Goal of DevKit
+### Setting Up a Project
 
-DevKit's goal is to provide a large set of libraries that can be used to manage, develop, deploy and
-analyze your code.
+Install the Angular CLI globally:
 
-# Getting Started - Local Development
-
-## Installation
-
-To get started locally, follow these instructions:
-
-1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
-1. Clone to your local computer using `git`.
-1. Make sure that you have Node 12.14 or 14.0 installed. See instructions [here](https://nodejs.org/en/download/).
-1. Make sure that you have `yarn` installed; see instructions [here](https://yarnpkg.com/lang/en/docs/install/).
-1. Run `yarn` (no arguments) from the root of your clone of this project to install dependencies.
-
-## Building and Installing the CLI
-
-To make a local build:
-
-```shell
-yarn build --local
+```
+npm install -g @angular/cli
 ```
 
-This generates a number of tarballs in the `dist/` directory. To actually use
-the locally built tools, switch to another repository reproducing the specific
-issue you want to fix (or just generate a local repo with `ng new`). Then
-install the locally built packages:
+Create workspace:
 
-```shell
-cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
-npm install -D ${CLI_REPO}/dist/*.tgz
+```
+ng new [PROJECT NAME]
 ```
 
-Builds of this example project will use tooling created from the previous local
-build and include any local changes. When using the CLI, it will automatically
-check for a local install and use that if present. This means you can just run:
+Run the application:
 
-```shell
-npm install -g @angular/cli
+```
+cd [PROJECT NAME]
+ng serve
 ```
 
-to get a global install of the latest CLI release. Then running any `ng` command
-in the example project will automatically find and use the local build of the
-CLI.
-
-Note: If you are testing `ng update`, be aware that installing all the tarballs
-will also update the framework (`@angular/core`) to the latest version. In this
-case, simply install the CLI alone with
-`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
-project remains to be upgraded with `ng update`.
+Angular is cross-platform, fast, scalable, has incredible tooling, and is loved by millions.
 
-## Debugging
+## Quickstart
 
-To debug an invocation of the CLI, [build and install the CLI for an example
-project](#building-and-installing-the-cli), then run the desired `ng` command
-as:
+[Get started in 5 minutes][quickstart].
 
-```shell
-node --inspect-brk node_modules/.bin/ng ...
-```
+## Ecosystem
 
-This will trigger a breakpoint as the CLI starts up. You can connect to this
-using the supported mechanisms for your IDE, but the simplest option is to open
-Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
-link for the `node_modules/.bin/ng` Node target.
+<p>
+  <img src="/docs/images/angular-ecosystem-logos.png" alt="angular ecosystem logos" width="500px" height="auto">
+</p>
 
-Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
-the debugger is not aware of all the source code files before hand. As a result,
-it is tough to put breakpoints on files before the CLI loads them. The easiest
-workaround is to use the `debugger;` statement to stop execution in the file you
-are interested in, and then you should be able to step around and set breakpoints
-as expected.

-## Testing
+## Changelog
 
-There are two different test suites which can be run locally:
+[Learn about the latest improvements][changelog].
 
-### Unit tests
-  * Run all tests: `yarn bazel test //packages/...`
-  * Run a subset of the tests, use the full Bazel target example: `yarn bazel test //packages/schematics/angular:angular_test`
-  * For a complete list of test targets use the following Bazel query: `yarn bazel query "tests(//packages/...)"`
+## Upgrading
 
-You can find more info about debugging [tests with Bazel in the docs.](https://github.com/angular/angular-cli/blob/master/docs/process/bazel.md#debugging-jasmine_node_test)  
+Check out our [upgrade guide](https://update.angular.dev/) to find out the best way to upgrade your project.
 
-### End to end tests
-  * Run: `node tests/legacy-cli/run_e2e.js`
-  * Run a subset of the tests: `node tests/legacy-cli/run_e2e.js tests/legacy-cli/e2e/tests/i18n/ivy-localize-*`
+## Contributing
 
-When running the debug commands, Node will stop and wait for a debugger to attach.
-You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also, see [IDE Specific Usage](#ide-specific-usage) for a
-simpler debug story.
+### Contributing Guidelines
 
-When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
-and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.
+Read through our [contributing guidelines][contributing] to learn about our submission process, coding rules and more.
 
-## IDE Specific Usage
+### Want to Help?
 
-Some additional tips for developing in specific IDEs.
+Want to report a bug, contribute some code, or improve documentation? Excellent! Read up on our guidelines for [contributing][contributing] and then check out one of our issues labeled as <kbd>[help wanted](https://github.com/angular/angular-cli/labels/help%20wanted)</kbd> or <kbd>[good first issue](https://github.com/angular/angular-cli/labels/good%20first%20issue)</kbd>.
 
-### Intellij IDEA / WebStorm
+### Code of Conduct
 
-To load the project in Intellij products, simply `Open` the repository folder.
-Do **not** `Import Project`, because that will overwrite the existing
-configuration.
+Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][codeofconduct].
 
-Once opened, the editor should automatically detect run configurations in the
-workspace. Use the drop down to choose which one to run and then click the `Run`
-button to start it. When executing a debug target, make sure to click the
-`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
-wait forever for a debugger to attach).
+### Developer Guide
 
-![Intellij IDEA run configurations](docs/images/run-configurations.png)
+Read through our [developer guide][developer] to learn about how to build and test the Angular CLI locally.
 
-## Creating New Packages
 
-Adding a package to this repository means running two separate commands:
+## Community
 
-1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
-  base files for the new package (package.json, src/index, etc).
-1. `devkit-admin templates`. This will update the README and all other template files that might
-  have changed when adding a new package.
+Join the conversation and help the community.
 
-For private packages, you will need to add a `"private": true` key to your package.json manually.
-This will require re-running the template admin script.

+# Building and Testing Angular CLI
+
+## Installation
+
+To get started locally, follow these instructions:
+
+1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
+2. If you are on Windows, see [the extra steps needed for contributing on Windows](#windows)
+3. Clone to your local computer using `git`.
+4. Make sure that you have Node `v20.19.0` or higher installed. See instructions [here](https://nodejs.org/en/download/).
+5. Install `pnpm`.
+   - You can install pnpm by running `npm i -g pnpm@9`.
+   - See detailed instructions [here](https://pnpm.io/installation).
+6. Run `pnpm install` from the root of your clone of this project to install dependencies.
+
+## Building and Installing the CLI
+
+To make a local build:
+
+```shell
+pnpm build --local
+```
+
+This generates a number of tarballs in the `dist/` directory. To actually use
+the locally built tools, switch to another repository reproducing the specific
+issue you want to fix (or just generate a local repo with `ng new`). Then
+install the locally built packages:
+
+```shell
+cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
+npm install -D ${CLI_REPO}/dist/*.tgz
+```
+
+Builds of this example project will use tooling created from the previous local
+build and include any local changes. When using the CLI, it will automatically
+check for a local install and use that if present. This means you can just run:
+
+```shell
+npm install -g @angular/cli
+```
+
+to get a global install of the latest CLI release. Then running any `ng` command
+in the example project will automatically find and use the local build of the
+CLI.
+
+Note: If you are testing `ng update`, be aware that installing all the tarballs
+will also update the framework (`@angular/core`) to the latest version. In this
+case, simply install the CLI alone with
+`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
+project remains to be upgraded with `ng update`.
+
+## Debugging
+
+To debug an invocation of the CLI, [build and install the CLI for an example
+project](#building-and-installing-the-cli), then run the desired `ng` command
+as:
+
+```shell
+node --inspect-brk node_modules/.bin/ng ...
+```
+
+This will trigger a breakpoint as the CLI starts up. You can connect to this
+using the supported mechanisms for your IDE, but the simplest option is to open
+Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
+link for the `node_modules/.bin/ng` Node target.
+
+Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
+the debugger is not aware of all the source code files before hand. As a result,
+it is tough to put breakpoints on files before the CLI loads them. The easiest
+workaround is to use the `debugger;` statement to stop execution in the file you
+are interested in, and then you should be able to step around and set breakpoints
+as expected.
+
+## Testing
+
+There are two different test suites which can be run locally:
+
+### Unit tests
+
+- Run all tests: `pnpm bazel test //packages/...`
+- Run a subset of the tests, use the full Bazel target example: `pnpm bazel test //packages/schematics/angular:angular_test`
+- For a complete list of test targets use the following Bazel query: `pnpm bazel query "tests(//packages/...)"`
+
+When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
+and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.
+
+You can find more info about debugging [tests with Bazel in the docs.](https://github.com/angular/angular-cli/blob/main/docs/process/bazel.md#debugging-jasmine_node_test)
+
+### End to end tests
+
+- For a complete list of test targets use the following Bazel query: `pnpm bazel query "tests(//tests/...)"`
+- Run a subset of the tests: `pnpm bazel test //tests:e2e_node22 --config=e2e --test_filter="tests/i18n/ivy-localize-*"`
+- Use `bazel run` to debug failing tests debugging: `pnpm bazel run //tests:e2e_node22 --config=e2e --test_arg="--glob=tests/basic/aot.ts"`
+- Provide additional `e2e_runner` options using `--test_arg`: `--test_arg="--package-manager=yarn"`
+
+When running the debug commands, Node will stop and wait for a debugger to attach.
+You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also, see [IDE Specific Usage](#ide-specific-usage) for a
+simpler debug story.
+
+## IDE Specific Usage
+
+Some additional tips for developing in specific IDEs.
+
+### Intellij IDEA / WebStorm
+
+To load the project in Intellij products, simply `Open` the repository folder.
+Do **not** `Import Project`, because that will overwrite the existing
+configuration.
+
+Once opened, the editor should automatically detect run configurations in the
+workspace. Use the drop down to choose which one to run and then click the `Run`
+button to start it. When executing a debug target, make sure to click the
+`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
+wait forever for a debugger to attach).
+
+![Intellij IDEA run configurations](images/run-configurations.png)
+
+### VS Code
+
+In order to debug some Angular CLI behaviour using Visual Studio Code, you can run `npm run build`, and then use a launch configuration like the following:
+
+```json
+{
+  "type": "node",
+  "request": "launch",
+  "name": "ng serve",
+  "cwd": "<path to an Angular project generated with Angular-CLI>",
+  "program": "${workspaceFolder}/dist/@angular/cli/bin/ng",
+  "args": [
+    "<ng command>",
+    ...other arguments
+  ],
+  "console": "integratedTerminal"
+}
+```
+
+Then you can add breakpoints in `dist/@angular` files.
+
+For more information about Node.js debugging in VS Code, see the related [VS Code Documentation](https://code.visualstudio.com/docs/nodejs/nodejs-debugging).
+
+## CPU Profiling
+
+In order to investigate performance issues, CPU profiling is often useful.
+
+### Creating a profile
+
+Node.js 16+ users can use the Node.js command line argument `--cpu-prof` to create a CPU profile.
+
+```bash
+node --cpu-prof node_modules/.bin/ng build
+```
+
+In addition to this one, another, more elaborated way to capture a CPU profile using the Chrome Devtools is detailed in https://github.com/angular/angular-cli/issues/8259#issue-269908550.
+
+#### Opening a profile
+
+You can use the Chrome Devtools to process it. To do so:
+
+1. open `chrome://inspect` in Chrome
+1. click on "Open dedicated DevTools for Node"
+1. go to the "profiler" tab
+1. click on the "Load" button and select the generated `.cpuprofile` file
+1. on the left panel, select the associated file
+
+## Creating New Packages
+
+Adding a package to this repository means running two separate commands:
+
+1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
+   base files for the new package (package.json, src/index, etc).
+1. `devkit-admin templates`. This will update the README and all other template files that might
+   have changed when adding a new package.
+
+For private packages, you will need to add a `"private": true` key to your package.json manually.
+This will require re-running the template admin script.
+
+## Windows
+
+To contribute to Angular using a Windows machine, you need to use the [Windows Linux Subsystem](https://learn.microsoft.com/en-us/windows/wsl/about) (also known as WSL).
+Installing WSL on your machine requires a few extra steps, but we believe it's generally useful for developing on Windows:
+
+1.  Run `wsl --install` from Powershell (as administrator).
+2.  Restart your machine.
+3.  Enter the WSL environment by running: `wsl`.
+4.  Continue with the developer guide as if you were on a native Linux system.
+
+For a more detailed guide, refer to the official Microsoft documentation: [Installing WSL](https://learn.microsoft.com/en-us/windows/wsl/install).
+
+**Note:** Angular continues to support native Windows development via the `ng` CLI and rigorously tests on Windows for every code change. This recommendation specifically applies to contributing to the Angular codebase itself.

-# Operating System and Node Version
+## Debugging
 
-A User Agent string is built to "fool" Google Analytics into reading the Operating System and
-version fields from it. The base dimensions are used for those.
+Using `NG_DEBUG=1` will enable Google Analytics debug mode, To view the debug events, in Google Analytics go to `Configure > DebugView`.
 
-Node version is our App ID, but a dimension is also used to get the numeric MAJOR.MINOR of node.
-
-# Debugging
-
-Using `DEBUG=universal-analytics` will report all calls to the universal-analytics library,
-including queuing events and sending them to the server.
-
-Using `DEBUG=ng:analytics` will report additional information regarding initialization and
-decisions made during the usage analytics process, e.g. if the user has analytics disabled.
-
-Using `DEBUG=ng:analytics:command` will show the decisions made by the command runner.
-
-Using `DEBUG=ng:analytics:log` will show what we actually send to GA.
-
-See [the `debug` NPM library](https://www.npmjs.com/package/debug) for more information.

-# Disabling Usage Analytics
+## Disabling Usage Analytics
 
 There are 2 ways of disabling usage analytics:
 
-1. using `ng analytics off` (or changing the global configuration file yourself). This is the same
+1. using `ng analytics disable --global` (or changing the global configuration file yourself). This is the same
    as answering "No" to the prompt.
 1. There is an `NG_CLI_ANALYTICS` environment variable that overrides the global configuration.
    That flag is a string that represents the User ID. If the string `"false"` is used it will
-   disable analytics for this run. If the string `"ci"` is used it will show up as a CI run (see
-   below).
-
-# CI
-
-A special user named `ci` is used for analytics for tracking CI information. This is a convention
-and is in no way enforced.
-
-Running on CI by default will disable analytics (because of a lack of TTY on STDIN/OUT). It can be
-manually enabled using either a global configuration with a value of `ci`, or using the
-`NG_CLI_ANALYTICS=ci` environment variable.
+   disable analytics for this run.

 # Release
 
-For each version to be released, check out the associated branch and:
-
-1. Increment the CLI version number in
-   [`package.json`](https://github.com/angular/angular-cli/blob/master/package.json).
-1. Update `Angular` version in
-   [`packages/schematics/angular/utility/latest-versions.ts`](https://github.com/angular/angular-cli/blob/master/packages/schematics/angular/utility/latest-versions.ts)
-   to match the lastest framework patch version for the associated minor.
-   - This number _usually_ aligns with the CLI version **but not always**. Framework may have
-     required a hotfix release, which could desync the two version numbers. Check the latest version
-     with `yarn info @angular/core dist-tags` or look at the most recent FW release in the
-     [#news channel](https://angular-team.slack.com/archives/C0439GUGA).
-
-As commits are cherry-picked when PRs are merged, creating the release should be a matter of creating a tag.
-
-```bash
-git add packages/schematics/angular/utility/latest-versions.ts package.json
-git commit -m 'release: vXX'
-git tag -a 'vXX' -m 'release: tag vXX'
-```
-
-The package versions we are about to publish are derived from `version` in the root
-[`package.json`](https://github.com/angular/angular-cli/blob/master/package.json#L3). Double check that the versions are correct by running the
-following command.
-
-```bash
-yarn admin packages --releaseCheck
-```
-
-Now push the commit and the tag to the upstream repository. **Make sure to use
-`--follow-tags`, as tags need to be pushed immediately or CI may fail!**
-
-```bash
-git push upstream --follow-tags
-```
-
-## Authenticating
-
-**This can ONLY be done by a Google employee.**
-
-Log in to the Wombat publishing service using your own github and google.com
-account to publish. This enforces the login is done using 2Factor auth.
-
-Run `npm login --registry https://wombat-dressing-room.appspot.com`:
-
-1. In the new browser tab, the registry app will ask you to connect with GitHub to create a token
-1. After connecting with github, you will be redirected to create a token
-1. Upon redirect, an auth token is added to your ~/.npmrc for the proxy
-
-After closing the tab, you have successfully logged in, it is time to publish.
-
-**NOTE: After publishing, remove the token added to your `~/.npmrc` file to logout.**
-
-## Publishing
+Releasing is performed using Angular's unified release tooling. Each week, two releases are expected, `latest` and `next` on npm.
 
-**This can ONLY be done by a Google employee.**
+**DURING a minor OR major CLI release:**
 
-**Wait for CI to be green after pushing the release commit.**
+Once FW releases the actual minor/major release (for example: `13.0.0` or `13.1.0`), update dependencies with the following:
 
-For the first release of a major version, follow the instructions in
-[Publishing a Major Version](#publishing-a-major-version) section.
+1.  Update [`constants.bzl`](../../constants.bzl) so `@angular/core` and `ng-packagr` are using the release version (drop `-rc.*`).
+2.  Update all `package.json` dependencies on framework packages to to the release version (drop `-rc.*`).
+    - Components packages release _after_ CLI, so those should be left as `-rc.*`.
+3.  `pnpm install` to update the `pnpm-lock.yaml` file.
 
-For non-major release, check out the patch branch (e.g. `9.1.x`), then run:
+Create a PR with the above changes ([example](https://github.com/angular/angular-cli/pull/31872)) and merge it directly to the RC
+branch. This PR must land _after_ FW releases (or else CI will fail) but _before_ the CLI release PR. Releases are built before
+the PR is sent for review, so any changes after that point won't be included in the release and this cannot be combined with the
+release PR.
 
-```bash
-rm -rf node_modules/ && yarn install --frozen-lockfile # Reload dependencies
-yarn admin publish --tag latest
-```
-
-If also publishing a prerelease, check out `master`, then run:
-
-```bash
-rm -rf node_modules/ && yarn install --frozen-lockfile # Reload dependencies
-yarn admin publish --tag next
-```
-
-If also publish an LTS branch, check out that patch branch (e.g. `8.3.x`), then
-run:
-
-**Make sure to update the NPM tag for the version you are releasing!**
-
-```bash
-rm -rf node_modules/ && yarn # Reload dependencies
-yarn admin publish --tag v8-lts
-```
-
-## Release Notes
-
-`yarn run -s admin changelog` takes `from` and `to` arguments which are any valid git
-ref.
+**AFTER a minor OR major CLI release:**
 
-For example, running the following command will output the release notes on
-stdout between v1.2.3 and 1.2.4:
+`constants.bzl` also needs to be updated to use `-next.0` after a major or minor release. However this needs to happen _after_ FW
+publishes the initial `-next.0` release, which will happen 1 week after the major or minor release.
 
-```bash
-yarn run -s admin changelog --from=v1.2.3 --to=v1.2.4
-```
-
-Copy the output (you can use `| pbcopy` on MacOS or `| xclip` on Linux) and
-paste the release notes on [GitHub](https://github.com/angular/angular-cli/releases)
-for the tag just released.
-
-If you have an API token for GitHub you can create a draft automatically by
-using the `--githubToken` flag. You just then have to confirm the draft.
-
-> **Tags containing `next` or `rc` should be marked as pre-release.**

+## Releasing the CLI
 
-## Publishing a Major Version
+Typical patch and next releases do not require FW to release in advance, as CLI does not pin the FW
+dependency.
 
-For the first release of a major version, say `v10.0.0`, checkout the major branch

+navigate the prompts:
 
-```bash
-yarn # Reload dependencies
-yarn admin publish --tag next # a major release is always tagged as next initially
-```
-
-Confirm with downstream repositories (Components, etc) that everything is ok.
-Once the release is stable, wait for Framework to retag their packages, then
-retag the CLI packages as `latest`.
-The command below will automatically retag stable packages as well as experimental
-packages.

-click the "+ Google Calendar" button in the bottom right to add it to your Google
-Calendar account. You should then be able to find and modify events on

+Releases should be done in "reverse semver order", meaning they should follow:
+
+Oldest LTS -> Newest LTS -> Patch -> RC -> Next
+
+This can skip any versions which don't need releases, so most weeks are just "Patch -> Next".
+
+## Releasing a new package
+
+Wombat has some special access requirements which need to be configured to publish a new NPM package.
+
+See [this Wombat doc](http://g3doc/company/teams/cloud-client-libraries/team/automation/docs/npm-publish-service#existing-package)
+and [this postmortem](http://docs/document/d/1emx2mhvF5xMzNUlDrVRYKI_u4iUOnVrg3rV6c5jk2is?resourcekey=0-qpsFbBfwioYT4f6kyUm8ZA&tab=t.0)
+for more info.
+
+Angular is _not_ an organization on NPM, therefore each package is published
+independently and Wombat access needs to be managed individually. This also means
+we can't rely on Wombat already having access to a new package.
+
+In order to configure a brand new NPM package, it first needs to be published
+manually so we can add Wombat access to it. Note that this step can and should be
+done prior to weekly releases. The sooner this can be done, the less likely it
+will block the next weekly release.
+
+1.  Check out the `main` branch, which should always have a `-next` version.
+    - This avoids having the initial publish actually be used in production.
+1.  Trigger a release build locally.
+    ```shell
+    nvm install
+    pnpm install --frozen-lockfile
+    pnpm ng-dev release build
+    ```
+1.  Log in to NPM as `angular`.
+
+    ```shell
+    npm login
+    ```
+
+    - See these two Valentine entries for authentication details:
+      - https://valentine.corp.google.com/#/show/1460636514618735
+      - https://valentine.corp.google.com/#/show/1531867371192103
+
+1.  Publish the release.
+    ```shell
+    (cd dist/releases/my-scope/my-pkg/ && npm publish --access public)
+    ```
+1.  Add Wombat to the package.
+    ```shell
+    npm owner add google-wombot @my-scope/my-pkg
+    ```
+1.  Don't forget to logout.
+    ```shell
+    npm logout
+    ```
+1.  File a bug like [b/336626936](http://b/336626936) to ask Wombat maintainers to
+    accept the invite for the new package.
+
+Once Wombat accepts the invite, regular automated releases should work as expected.
+
+## Updating Browser Support
+
+Angular's browser support is defined by a [Baseline](https://web.dev/baseline)
+"widely available" date. Before a new major version is released, this should be
+updated to approximately the current date.
+
+A few weeks before a major (around feature freeze):
+
+1.  Update `BASELINE_DATE` in
+    [`/constants.bzl`](/constants.bzl) to the end of the most recent month.
+    - For example, if it is currently May 12th, set `baselineThreshold` to April
+      30th.
+    - Picking a date at the end of a month makes it easier to cross-reference
+      Angular's support with other tools (like MDN) which state Baseline support
+      using month specificity.
+    - Commit and merge the change, no other alterations or automation is
+      necessary in the CLI repo.
+2.  Update the date in the `ng-packagr` repo.
+    [`/.stylesheet-processor.ts`](https://github.com/ng-packagr/ng-packagr/blob/main/src/lib/styles/stylesheet-processor.ts#L25).
+3.  Update
+    [`angular.dev` documentation](https://github.com/angular/angular/tree/main/adev/src/content/reference/versions.md#browser-support)
+    to specify the date used and link to [browsersl.ist](https://browsersl.ist)
+    with the generated configuration.

+# Schematics Collections (`schematicCollections`)
+
+The `schematicCollections` can be placed under the `cli` option in the global `.angular.json` configuration, at the root or at project level in `angular.json` .
+
+```jsonc
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

+  "cli": {
+    "schematicCollections": ["@schematics/angular", "@angular/material"]
+  }
+  // ...
+}
+```
+
+## Rationale
+
+When this option is not configured and a user would like to run a schematic which is not part of `@schematics/angular`,
+the collection name needs to be provided to `ng generate` command in the form of `[collection-name:schematic-name]`. This make the `ng generate` command too verbose for repeated usages.
+
+This is where the `schematicCollections` option can be useful. When adding `@angular/material` to the list of `schematicCollections`, the generate command will try to locate the schematic in the specified collections.
+
+```
+ng generate navigation
+```
+
+is equivalent to:
+
+```
+ng generate @angular/material:navigation
+```
+
+## Conflicting schematic names
+
+When multiple collections have a schematic with the same name. Both `ng generate` and `ng new` will run the first schematic matched based on the ordering (as specified) of `schematicCollections`.

+# Important Considerations when Using Angular Universal
+
+## Introduction
+
+Although the goal of the Universal project is the ability to seamlessly render an Angular
+application on the server, there are some inconsistencies that you should consider. First,
+there is the obvious discrepancy between the server and browser environments. When rendering
+on the server, your application is in an ephemeral or "snapshot" state. The application is
+fully rendered once, with the resulting HTML returned, and the remaining application state
+destroyed until the next render. Next, the server environment inherently does not have the
+same capabilities as the browser (and has some that likewise the browser does not). For
+instance, the server does not have any concept of cookies. You can polyfill this and other
+functionality, but there is no perfect solution for this. In later sections, we'll walk
+through potential mitigations to reduce the scope of errors when rendering on the server.
+
+Please also note the goal of SSR: improved initial render time for your application. This
+means that anything that has the potential to reduce the speed of your application in this
+initial render should be avoided or sufficiently guarded against. Again, we'll review how
+to accomplish this in later sections.
+
+## "window is not defined"
+
+One of the most common issues when using Angular Universal is the lack of browser global
+variables in the server environment. This is because the Universal project uses
+[domino](https://github.com/fgnass/domino) as the server DOM rendering engine. As a result,
+there is certain functionality that won't be present or supported on the server. This
+includes the `window` and `document` global objects, cookies, certain HTML elements (like canvas),
+and several others. There is no exhaustive list, so please be aware of the fact that if you
+see an error like this, where a previously-accessible global is not defined, it's likely because
+that global is not available through domino.
+
+> Fun fact: Domino stands for "DOM in Node"
+
+### How to fix?
+
+#### Strategy 1: Injection
+
+Frequently, the needed global is available through the Angular platform via Dependency Injection (DI).
+For instance, the global `document` is available through the `DOCUMENT` token. Additionally, a _very_
+primitive version of both `window` and `location` exist through the `DOCUMENT` object. For example:
+
+```ts
+// example.service.ts
+import { Injectable, Inject } from '@angular/core';
+import { DOCUMENT } from '@angular/common';
+
+@Injectable()
+export class ExampleService {
+  constructor(@Inject(DOCUMENT) private _doc: Document) {}
+
+  getWindow(): Window | null {
+    return this._doc.defaultView;
+  }
+
+  getLocation(): Location {
+    return this._doc.location;
+  }
+
+  createElement(tag: string): HTMLElement {
+    return this._doc.createElement(tag);
+  }
+}
+```
+
+Please be judicious about using these references, and lower your expectations about their capabilities. `localStorage`
+is one frequently-requested API that won't work how you want it to out of the box. If you need to write your own library
+components, please consider using this method to provide similar functionality on the server (this is what Angular CDK
+and Material do).
+
+#### Strategy 2: Guards
+
+If you can't inject the proper global value you need from the Angular platform, you can "guard" against
+invocation of browser code, so long as you don't need to access that code on the server. For instance,
+often invocations of the global `window` element are to get window size, or some other visual aspect.
+However, on the server, there is no concept of "screen", and so this functionality is rarely needed.
+
+You may read online and elsewhere that the recommended approach is to use `isPlatformBrowser` or
+`isPlatformServer`. This guidance is **incorrect**. This is because you wind up creating platform-specific
+code branches in your application code. This not only increases the size of your application unnecessarily,
+but it also adds complexity that then has to be maintained. By separating code into separate platform-specific
+modules and implementations, your base code can remain about business logic, and platform-specific exceptions
+are handled as they should be: on a case-by-case abstraction basis. This can be accomplished using Angular's Dependency
+Injection (DI) in order to remove the offending code and drop in a replacement at runtime. Here's an example:
+
+```ts
+// window-service.ts
+import { Injectable } from '@angular/core';
+
+@Injectable()
+export class WindowService {
+  getWidth(): number {
+    return window.innerWidth;
+  }
+}
+```
+
+```ts
+// server-window.service.ts
+import { Injectable } from '@angular/core';
+import { WindowService } from './window.service';
+
+@Injectable()
+export class ServerWindowService extends WindowService {
+  getWidth(): number {
+    return 0;
+  }
+}
+```
+
+```ts
+// app-server.module.ts
+import {NgModule} from '@angular/core';
+import {WindowService} from './window.service';
+import {ServerWindowService} from './server-window.service';
+
+@NgModule({
+  providers: [{
+    provide: WindowService,
+    useClass: ServerWindowService,
+  }]
+})
+```
+
+If you have a component provided by a third-party that is not Universal-compatible out of the box,
+you can create two separate modules for browser and server (the server module you should already have),
+in addition to your base app module. The base app module will contain all of your platform-agnostic code,
+the browser module will contain all of your browser-specific/server-incompatible code, and vice-versa for
+your server module. In order to avoid editing too much template code, you can create a no-op component
+to drop in for the library component. Here's an example:
+
+```ts
+// example.component.ts
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'example-component',
+  template: `<library-component></library-component>`, // this is provided by a third-party lib
+  // that causes issues rendering on Universal
+})
+export class ExampleComponent {}
+```
+
+```ts
+// app.module.ts
+import {NgModule} from '@angular/core';
+import {ExampleComponent} from './example.component';
+
+@NgModule({
+  declarations: [ExampleComponent],
+})
+```
+
+```ts
+// browser-app.module.ts
+import {NgModule} from '@angular/core';
+import {LibraryModule} from 'some-lib';
+import {AppModule} from './app.module';
+
+@NgModule({
+  imports: [AppModule, LibraryModule],
+})
+```
+
+```ts
+// library-shim.component.ts
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'library-component',
+  template: '',
+})
+export class LibraryShimComponent {}
+```
+
+```ts
+// server.app.module.ts
+import { NgModule } from '@angular/core';
+import { LibraryShimComponent } from './library-shim.component';
+import { AppModule } from './app.module';
+
+@NgModule({
+  imports: [AppModule],
+  declarations: [LibraryShimComponent],
+})
+export class ServerAppModule {}
+```
+
+#### Strategy 3: Shims
+
+If all else fails, and you simply must have access to some sort of browser functionality, you can patch
+the global scope of the server environment to include the globals you need. For instance:
+
+```ts
+// server.ts
+global['window'] = {
+  // properties you need implemented here...
+};
+```
+
+This can be applied to any undefined element. Please be careful when you do this, as playing with the global
+scope is generally considered an anti-pattern.
+
+> Fun fact: a shim is a patch for functionality that will never be supported on a given platform. A
+> polyfill is a patch for functionality that is planned to be supported, or is supported on newer versions
+
+## Application is slow, or worse, won't render
+
+The Angular Universal rendering process is straightforward, but just as simply can be blocked or slowed down
+by well-meaning or innocent-looking code. First, some background on the rendering process. When a render
+request is made for platform-server (the Angular Universal platform), a single route navigation is executed.
+When that navigation completes, meaning that all Zone.js macrotasks are completed, the DOM in whatever state
+it's in at that time is returned to the user.
+
+> A Zone.js macrotask is just a JavaScript macrotask that executes in/is patched by Zone.js
+
+This means that if there is a process, like a microtask, that takes up ticks to complete, or a long-standing
+HTTP request, the rendering process will not complete, or will take longer. Macrotasks include calls to globals
+like `setTimeout` and `setInterval`, and `Observables`. Calling these without cancelling them, or letting them run
+longer than needed on the server could result in suboptimal rendering.
+
+> It may be worth brushing up on the JavaScript event loop and learning the difference between microtasks
+> and macrotasks, if you don't know it already. [Here's](https://javascript.info/event-loop) a good reference.
+
+## My HTTP, Firebase, WebSocket, etc. won't finish before render!
+
+Similarly to the above section on waiting for macrotasks to complete, the flip-side is that the platform will
+not wait for microtasks to complete before finishing the render. In Angular Universal, we have patched the
+Angular HTTP client to turn it into a macrotask, to ensure that any needed HTTP requests complete for a given
+render. However, this type of patch may not be appropriate for all microtasks, and so it is recommended you use
+your best judgment on how to proceed. You can look at the code reference for how Universal wraps a task to turn
+it into a macrotask, or you can simply opt to change the server behavior of the given tasks.

-# `/lib` Folder
-
-This folder includes bootstrap code for the various tools included in this repository. Also
-included is the packages meta-information package in `packages.ts`. This is used to read and
-understand all the monorepo information (contained in the `.monorepo.json` file, and `package.json`
-files across the repo).
-
-`bootstrap-local.js` should be included when running files from this repository without compiling
-first. It allows for compiling and loading packages in memory directly from the repo. Not only

+# HelloWorldApp
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 1.7.0-beta.1.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate --help` to see all the available schematics you can generate.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/main/README.md).

-## Installation
-
-**BEFORE YOU INSTALL:** please read the [prerequisites](#prerequisites)
-
-### Install Globally
-
-```bash
-npm install -g @angular/cli
-```
-
-### Install Locally
-
-```bash
-npm install @angular/cli
-```
-
-To run a locally installed version of the angular-cli, you can call `ng` commands directly by adding the `.bin` folder within your local `node_modules` folder to your PATH. The `node_modules` and `.bin` folders are created in the directory where `npm install @angular/cli` was run upon completion of the install command.
-
-Alternatively, you can install [npx](https://www.npmjs.com/package/npx) and run `npx ng <command>` within the local directory where `npm install @angular/cli` was run, which will use the locally installed angular-cli.
-
-### Install Specific Version (Example: 6.1.1)
-
-```bash
-npm install -g @angular/cli@6.1.1
-```
-
-## Usage
-
-```bash
-ng help
-```
-
-### Generating and serving an Angular project via a development server
-
-```bash
-ng new PROJECT-NAME
-cd PROJECT-NAME
-ng serve
-```
-
-Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-You can configure the default HTTP host and port used by the development server with two command-line options :
-
-```bash
-ng serve --host 0.0.0.0 --port 4201
-```
-
-### Generating Components, Directives, Pipes and Services
-
-You can use the `ng generate` (or just `ng g`) command to generate Angular components:
-
-```bash
-ng generate component my-new-component
-ng g component my-new-component # using the alias
-
-# components support relative path generation
-# if in the directory src/app/feature/ and you run
-ng g component new-cmp
-# your component will be generated in src/app/feature/new-cmp
-# but if you were to run
-ng g component ./newer-cmp
-# your component will be generated in src/app/newer-cmp
-# if in the directory src/app you can also run
-ng g component feature/new-cmp
-# and your component will be generated in src/app/feature/new-cmp
-```
-
-You can find all possible blueprints in the table below:
-
-| Scaffold                                               | Usage                             |
-| ------------------------------------------------------ | --------------------------------- |
-| [Component](https://angular.io/cli/generate#component) | `ng g component my-new-component` |
-| [Directive](https://angular.io/cli/generate#directive) | `ng g directive my-new-directive` |
-| [Pipe](https://angular.io/cli/generate#pipe)           | `ng g pipe my-new-pipe`           |
-| [Service](https://angular.io/cli/generate#service)     | `ng g service my-new-service`     |
-| [Class](https://angular.io/cli/generate#class)         | `ng g class my-new-class`         |
-| [Guard](https://angular.io/cli/generate#guard)         | `ng g guard my-new-guard`         |
-| [Interface](https://angular.io/cli/generate#interface) | `ng g interface my-new-interface` |
-| [Enum](https://angular.io/cli/generate#enum)           | `ng g enum my-new-enum`           |
-| [Module](https://angular.io/cli/generate#module)       | `ng g module my-module`           |
-
-angular-cli will add reference to `components`, `directives` and `pipes` automatically in the `app.module.ts`. If you need to add this references to another custom module, follow these steps:
-
-1. `ng g module new-module` to create a new module
-2. call `ng g component new-module/new-component`
-
-This should add the new `component`, `directive` or `pipe` reference to the `new-module` you've created.
-
-### Updating Angular CLI
-
-If you're using Angular CLI `1.0.0-beta.28` or less, you need to uninstall `angular-cli` package. It should be done due to changing of package's name and scope from `angular-cli` to `@angular/cli`:
-
-```bash
-npm uninstall -g angular-cli
-npm uninstall --save-dev angular-cli
-```
-
-To update Angular CLI to a new version, you must update both the global package and your project's local package.
-
-Global package:
-
-```bash
-npm uninstall -g @angular/cli

-
-## Development Hints for working on Angular CLI
-
-### Working with master
-
-```bash
-git clone https://github.com/angular/angular-cli.git
-yarn
-npm run build
-cd dist/@angular/cli
-npm link
-```
-
-`npm link` is very similar to `npm install -g` except that instead of downloading the package
-from the repo, the just built `dist/@angular/cli/` folder becomes the global package.
-Additionally, this repository publishes several packages and we use special logic to load all of them
-on development setups.
-
-Any changes to the files in the `angular-cli/` folder will immediately affect the global `@angular/cli` package,
-meaning that, in order to quickly test any changes you make to the cli project, you should simply just run `npm run build`
-again.
-
-Now you can use `@angular/cli` via the command line:
-
-```bash
-ng new foo
-cd foo
-npm link @angular/cli
-ng serve
-```
-
-`npm link @angular/cli` is needed because by default the globally installed `@angular/cli` just loads
-the local `@angular/cli` from the project which was fetched remotely from npm.
-`npm link @angular/cli` symlinks the global `@angular/cli` package to the local `@angular/cli` package.
-Now the `angular-cli` you cloned before is in three places:
-The folder you cloned it into, npm's folder where it stores global packages and the Angular CLI project you just created.
-
-You can also use `ng new foo --link-cli` to automatically link the `@angular/cli` package.
-
-Please read the official [npm-link documentation](https://docs.npmjs.com/cli/link)
-and the [npm-link cheatsheet](http://browsenpm.org/help#linkinganynpmpackagelocally) for more information.
-
-To run the Angular CLI E2E test suite, use the `node ./tests/legacy-cli/run_e2e` command.
-It can also receive a filename to only run that test (e.g. `node ./tests/legacy-cli/run_e2e tests/legacy-cli/e2e/tests/build/dev-build.ts`).
-
-As part of the test procedure, all packages will be built and linked.
-You will need to re-run `npm link` to re-link the development Angular CLI environment after tests finish.
-
-### Debugging with VS Code
-
-In order to debug some Angular CLI behaviour using Visual Studio Code, you can run `npm run build`, and then use a launch configuration like the following:
-
-```json
-{
-    "type": "node",
-    "request": "launch",
-    "name": "ng serve",
-    "cwd": "<path to an Angular project generated with Angular-CLI>",
-    "program": "${workspaceFolder}/dist/@angular/cli/bin/ng",
-    "args": [
-        "<ng command>",
-        ...other arguments
-    ],
-    "console": "integratedTerminal"
-}
-```
-
-Then you can add breakpoints in `dist/@angular` files.
-
-For more informations about Node.js debugging in VS Code, see the related [VS Code Documentation](https://code.visualstudio.com/docs/nodejs/nodejs-debugging).
-
-### CPU Profiling
-
-In order to investigate performance issues, CPU profiling is often useful.
-
-To capture a CPU profiling, you can:
-
-1. install the v8-profiler-node8 dependency: `npm install v8-profiler-node8 --no-save`
-1. set the NG_CLI_PROFILING Environment variable to the file name you want:
-   - on Unix systems (Linux & Mac OS X): ̀`export NG_CLI_PROFILING=my-profile`
-   - on Windows: ̀̀`setx NG_CLI_PROFILING my-profile`
-
-Then, just run the ng command on which you want to capture a CPU profile.
-You will then obtain a `my-profile.cpuprofile` file in the folder from which you ran the ng command.
-
-You can use the Chrome Devtools to process it. To do so:
-
-1. open `chrome://inspect/#devices` in Chrome
-1. click on "Open dedicated DevTools for Node"
-1. go to the "profiler" tab
-1. click on the "Load" button and select the generated .cpuprofile file
-1. on the left panel, select the associated file
-
-In addition to this one, another, more elaborated way to capture a CPU profile using the Chrome Devtools is detailed in https://github.com/angular/angular-cli/issues/8259#issue-269908550.

+ * needed to allow the use of a dynamic import expression without crashing older versions of Node.js that

-The command can be used to build a project of type "application" or "library".
-When used to build a library, a different builder is invoked, and only the `ts-config`, `configuration`, and `watch` options are applied.
-All other options apply only to building applications.
-
-The application builder uses the [webpack](https://webpack.js.org/) build tool, with default configuration options specified in the workspace configuration file (`angular.json`) or with a named alternative configuration.
-A "development" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the `--configuration development`.
-
-The configuration options generally correspond to the command options.
-You can override individual configuration defaults by specifying the corresponding options on the command line.
-The command can accept option names given in either dash-case or camelCase.
-Note that in the configuration file, you must specify names in camelCase.
-
-Some additional options can only be set through the configuration file,
-either by direct editing or with the `ng config` command.
-These include `assets`, `styles`, and `scripts` objects that provide runtime-global resources to include in the project.
-Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
-
-For further details, see [Workspace Configuration](guide/workspace-config).

-A workspace has a single CLI configuration file, `angular.json`, at the top level.
-The `projects` object contains a configuration object for each project in the workspace.
-
-You can edit the configuration directly in a code editor,
-or indirectly on the command line using this command.
-
-The configurable property names match command option names,
-except that in the configuration file, all names must use camelCase,
-while on the command line options can be given in either camelCase or dash-case.

-- By default, the files for a new initial application (with the same name as the workspace) are placed in the `src/` subfolder. Corresponding end-to-end tests are placed in the `e2e/` subfolder.

-
-- Subsequent applications that you generate in the workspace reside in the `projects/` subfolder.
-
-If you plan to have multiple applications in the workspace, you can create an empty workspace by setting the `--createApplication` option to false.
-You can then use `ng generate application` to create an initial application.
-This allows a workspace name different from the initial app name, and ensures that all applications reside in the `/projects` subfolder, matching the structure of the configuration file.

-Architect is the tool that the CLI uses to perform complex tasks such as compilation, according to provided configurations.

-and an optional set of named alternate configurations in the "configurations" object.
-
-For example, the "serve" target for a newly generated app has a predefined
-alternate configuration named "production".
-
-You can define new targets and their configuration options in the "architect" section

-Perform a basic update to the current stable release of the core framework and CLI by running the following command.
-
-```
-ng update @angular/cli @angular/core
-```
-
-To update to the next beta or pre-release version, use the `--next` option.
-
-To update from one major version to another, use the format
-
-```
-ng update @angular/cli@^<major_version> @angular/core@^<major_version>
-```
-
-We recommend that you always update to the latest patch version, as it contains fixes we released since the initial major release.
-For example, use the following command to take the latest 10.x.x version and use that to update.
-
-```
-ng update @angular/cli@^10 @angular/core@^10
-```
-
-For detailed information and guidance on updating your application, see the interactive [Angular Update Guide](https://update.angular.io/).

+keywords:
+  - '@if'
+  - 'control flow'
+  - 'conditional rendering'
+  - 'template syntax'

+  - '@else'
+  - '@else if'

+related_tools:
+  - 'modernize'
+---
+
+## Purpose
+
+The purpose of this pattern is to create dynamic user interfaces by controlling which elements are rendered to the DOM based on the application's state. This is a fundamental technique for building responsive and interactive components.
+
+## When to Use
+
+Use the `@if` block as the modern, preferred alternative to the `*ngIf` directive for all conditional rendering. It offers better type-checking and a cleaner, more intuitive syntax within the template.
+
+## Key Concepts
+
+- **`@if` block:** The primary syntax for conditional rendering in modern Angular templates. It evaluates a boolean expression and renders the content within its block if the expression is true.
+
+## Example Files
+
+### `conditional-content.component.ts`
+
+This is a self-contained standalone component that demonstrates the `@if` block with an optional `@else` block.
+
+```typescript
+import { Component, signal } from '@angular/core';
+
+@Component({
+  selector: 'app-conditional-content',
+  template: `
+    <button (click)="toggleVisibility()">Toggle Content</button>
+
+    @if (isVisible()) {
+      <div>This content is conditionally displayed.</div>
+    } @else {
+      <div>The content is hidden. Click the button to show it.</div>
+    }
+  `,
+})
+export class ConditionalContentComponent {
+  protected readonly isVisible = signal(true);
+
+  toggleVisibility(): void {
+    this.isVisible.update((v) => !v);
+  }
+}
+```
+
+## Usage Notes
+
+- The expression inside the `@if ()` block must evaluate to a boolean.
+- This example uses a signal, which is a common pattern, but any boolean property or method call from the component can be used.
+- The `@else` block is optional and is rendered when the `@if` condition is `false`.
+
+## How to Use This Example
+
+### 1. Import the Component
+
+In a standalone architecture, import the component into the `imports` array of the parent component where you want to use it.
+
+```typescript
+// in app.component.ts
+import { Component } from '@angular/core';
+import { ConditionalContentComponent } from './conditional-content.component';
+
+@Component({
+  selector: 'app-root',
+  imports: [ConditionalContentComponent],
+  template: `
+    <h1>My Application</h1>
+    <app-conditional-content></app-conditional-content>
+  `,
+})
+export class AppComponent {}
+```

+You can help the Angular Team to prioritize features and improvements by permitting the Angular team to send command-line command usage statistics to Google.
+The Angular Team does not collect usage statistics unless you explicitly opt in. When installing the Angular CLI you are prompted to allow global collection of usage statistics.
+If you say no or skip the prompt, no data is collected.
+
+### What is collected?
+
+Usage analytics include the commands and selected flags for each execution.
+Usage analytics may include the following information:
+
+- Your operating system \(macOS, Linux distribution, Windows\) and its version.
+- Package manager name and version \(local version only\).
+- Node.js version \(local version only\).
+- Angular CLI version \(local version only\).
+- Command name that was run.
+- Workspace information, the number of application and library projects.
+- For schematics commands \(add, generate and new\), the schematic collection and name and a list of selected flags.
+- For build commands \(build, serve\), the builder name, the number and size of bundles \(initial and lazy\), compilation units, the time it took to build and rebuild, and basic Angular-specific API usage.
+
+Only Angular owned and developed schematics and builders are reported.
+Third-party schematics and builders do not send data to the Angular Team.

+The command can be used to build a project of type "application" or "library".
+When used to build a library, a different builder is invoked, and only the `ts-config`, `configuration`, `poll` and `watch` options are applied.
+All other options apply only to building applications.
+
+The application builder uses the [esbuild](https://esbuild.github.io/) build tool, with default configuration options specified in the workspace configuration file (`angular.json`) or with a named alternative configuration.
+A "development" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the `--configuration development`.
+
+The configuration options generally correspond to the command options.
+You can override individual configuration defaults by specifying the corresponding options on the command line.
+The command can accept option names given in dash-case.
+Note that in the configuration file, you must specify names in camelCase.
+
+Some additional options can only be set through the configuration file,
+either by direct editing or with the `ng config` command.
+These include `assets`, `styles`, and `scripts` objects that provide runtime-global resources to include in the project.
+Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
+
+For further details, see [Workspace Configuration](reference/configs/workspace-config).

+Angular CLI saves a number of cachable operations on disk by default.
+
+When you re-run the same build, the build system restores the state of the previous build and re-uses previously performed operations, which decreases the time taken to build and test your applications and libraries.
+
+To amend the default cache settings, add the `cli.cache` object to your [Workspace Configuration](reference/configs/workspace-config).
+The object goes under `cli.cache` at the top level of the file, outside the `projects` sections.
+
+```jsonc
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
+  "version": 1,
+  "cli": {
+    "cache": {
+      // ...
+    },
+  },
+  "projects": {},
+}
+```
+
+For more information, see [cache options](reference/configs/workspace-config#cache-options).
+
+### Cache environments
+
+By default, disk cache is only enabled for local environments. The value of environment can be one of the following:
+
+- `all` - allows disk cache on all machines.
+- `local` - allows disk cache only on development machines.
+- `ci` - allows disk cache only on continuous integration (CI) systems.
+
+To change the environment setting to `all`, run the following command:
+
+```bash
+ng config cli.cache.environment all
+```
+
+For more information, see `environment` in [cache options](reference/configs/workspace-config#cache-options).
+
+<div class="alert is-helpful">
+
+The Angular CLI checks for the presence and value of the `CI` environment variable to determine in which environment it is running.
+
+</div>
+
+### Cache path
+
+By default, `.angular/cache` is used as a base directory to store cache results.
+
+To change this path to `.cache/ng`, run the following command:
+
+```bash
+ng config cli.cache.path ".cache/ng"
+```

+Setting up autocompletion configures your terminal, so pressing the `<TAB>` key while in the middle
+of typing will display various commands and options available to you. This makes it very easy to
+discover and use CLI commands without lots of memorization.
+
+![A demo of Angular CLI autocompletion in a terminal. The user types several partial `ng` commands,
+using autocompletion to finish several arguments and list contextual options.
+](assets/images/guide/cli/completion.gif)
+
+## Automated setup
+
+The CLI should prompt and ask to set up autocompletion for you the first time you use it (v14+).
+Simply answer "Yes" and the CLI will take care of the rest.
+
+```
+$ ng serve
+? Would you like to enable autocompletion? This will set up your terminal so pressing TAB while typing Angular CLI commands will show possible options and autocomplete arguments. (Enabling autocompletion will modify configuration files in your home directory.) Yes
+Appended `source <(ng completion script)` to `/home/my-username/.bashrc`. Restart your terminal or run:
+
+source <(ng completion script)
+
+to autocomplete `ng` commands.
+
+# Serve output...
+```
+
+If you already refused the prompt, it won't ask again. But you can run `ng completion` to
+do the same thing automatically.
+
+This modifies your terminal environment to load Angular CLI autocompletion, but can't update your
+current terminal session. Either restart it or run `source <(ng completion script)` directly to
+enable autocompletion in your current session.
+
+Test it out by typing `ng ser<TAB>` and it should autocomplete to `ng serve`. Ambiguous arguments
+will show all possible options and their documentation, such as `ng generate <TAB>`.
+
+## Manual setup
+
+Some users may have highly customized terminal setups, possibly with configuration files checked
+into source control with an opinionated structure. `ng completion` only ever appends Angular's setup
+to an existing configuration file for your current shell, or creates one if none exists. If you want
+more control over exactly where this configuration lives, you can manually set it up by having your
+shell run at startup:
+
+```bash
+source <(ng completion script)
+```
+
+This is equivalent to what `ng completion` will automatically set up, and gives power users more
+flexibility in their environments when desired.
+
+## Platform support
+
+Angular CLI supports autocompletion for the Bash and Zsh shells on MacOS and Linux operating
+systems. On Windows, Git Bash and [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/)
+using Bash or Zsh are supported.
+
+## Global install
+
+Autocompletion works by configuring your terminal to invoke the Angular CLI on startup to load the
+setup script. This means the terminal must be able to find and execute the Angular CLI, typically
+through a global install that places the binary on the user's `$PATH`. If you get
+`command not found: ng`, make sure the CLI is installed globally which you can do with the `-g`
+flag:
+
+```bash
+npm install -g @angular/cli
+```

+The command takes an optional project name, as specified in the `projects` section of the `angular.json` workspace configuration file.
+When a project name is not supplied, executes the `lint` builder for all projects.
+
+To use the `ng lint` command, use `ng add` to add a package that implements linting capabilities. Adding the package automatically updates your workspace configuration, adding a lint [CLI builder](tools/cli/cli-builder).
+For example:
+
+```json
+"projects": {
+  "my-project": {

+</General Purpose>
+
+<Core Workflows & Tool Guide>
+* **1. Discover Project Structure (Mandatory First Step):** Always begin by calling
+  \`list_projects\` to understand the workspace. The \`path\` property for a workspace
+  is a required input for other tools.
+
+* **2. Get Coding Standards:** Before writing or changing code within a project, you **MUST** call
+  the \`get_best_practices\` tool with the \`workspacePath\` from the previous step to get
+  version-specific standards. For general knowledge, you can call the tool without this path.
+
+* **3. Answer User Questions:**
+    - For conceptual questions ("what is..."), use \`search_documentation\`.
+    - For code examples ("show me how to..."), use \`find_examples\`.
+</Core Workflows & Tool Guide>
+
+<Key Concepts>
+* **Workspace vs. Project:** A 'workspace' contains an \`angular.json\` file and defines 'projects'
+  (applications or libraries). A monorepo can have multiple workspaces.
+* **Targeting Projects:** Always use the \`workspaceConfigPath\` from \`list_projects\` when
+  available to ensure you are targeting the correct project in a monorepo.

+# `airules.md` - Modern Angular Tutor 🧑‍🏫
+
+Your primary role is to act as an expert, friendly, and patient **Angular tutor**. You will guide users step-by-step through the process of building a complete, modern Angular application using **Angular v20**. You will assume the user is already inside a newly created Angular project repository and that the application is **already running** with live-reload enabled in a web preview tab. Your goal is to foster critical thinking and retention by having the user solve project-specific problems that **cohesively build a tangible application** (the "Smart Recipe Box").
+
+Your role is to be a tutor and guide, not an automated script. You **must never** create, modify, or delete files in the user's project during the normal, step-by-step process of a lesson. The only exception is when a user explicitly asks to skip a module or jump to a different section. In these cases, you will present the necessary code changes and give the user the choice to either apply the changes themselves or have you apply them automatically.
+
+---
+
+## 📜 Core Principles
+
+These are the fundamental rules that govern your teaching style. Adhere to them at all times.
+
+### 1. Modern Angular First
+
+This is your most important principle. You will teach **Modern Angular** as the default, standard way to build applications, using the latest stable features.
+
+- ✅ **DO** teach with **Standalone Components as the default architecture**.
+- ✅ **DO** teach **Signals** for state management (`signal`, `computed`, `input`).
+- ✅ **DO** teach the built-in **control flow** (`@if`, `@for`, `@switch`) in templates.
+- ✅ **DO** teach the new v20 file naming conventions (e.g., `app.ts` for a component file).
+- ❌ **DO NOT** teach outdated patterns like `NgModules`, `ngIf`/`ngFor`/`ngSwitch`, or `@Input()` decorators unless a user specifically asks for a comparison. Frame them as "the old way" and note that as of v20, the core structural directives are officially deprecated.
+- **CRITICAL NOTE (Experimental Features)**: You **must prominently warn** the user whenever a module covers an **experimental or developer-preview feature** (currently Phase 5: Signal Forms). Emphasize that the API is subject to change.
+
+### 2. The Concept-Example-Exercise-Support Cycle
+
+Your primary teaching method involves guiding the user to solve problems themselves that directly contribute to their chosen application. Each new concept or feature should be taught using this **four-step** pattern:
+
+1.  **Explain Concept (The "Why" and "What")**: Clearly explain the Angular concept or feature, its purpose, and how it generally works. The depth of this explanation depends on the user's experience level.
+
+2.  **Provide Generic Example (The "How" in Isolation)**: **(MANDATORY)** You **MUST** provide a clear, well-formatted, concise code snippet that illustrates the core concept. **This example MUST NOT be code directly from the user's tutorial project ("Smart Recipe Box").** It should be a generic, illustrative example designed to show the concept in action (e.g., using a simple `Counter` to demonstrate a signal, or a generic `Logger` to explain dependency injection). This generic code should still follow all rules in `## ⚙️ Specific Technical & Syntax Rules`.
+
+3.  **Define Project Exercise (The "Apply it to Your App")**:
+    **IMPORTANT:** Your primary directive for creating a project exercise is to **describe the destination, not the journey.** You must present a high-level challenge by defining the properties of the _finished product_, not the steps to get there.
+    Your initial presentation of an exercise **MUST NEVER** contain a numbered or bulleted list of procedural steps, actions, or commands. You must strictly adhere to the following three-part structure:
+    _ **Objective**: A single paragraph in plain English describing the overall goal.
+    _ **Expected Outcome**: A clear description of the new behavior or appearance the user should see in the web preview upon successful completion.
+    _ **Closing**: An encouraging closing that explicitly states the user can ask for hints or a detailed step-by-step guide if they get stuck.
+    _ **Example of Correct vs. Incorrect Phrasing**
+    To make this rule crystal clear, here is how to convert a procedural, command-based exercise into the correct, state-based format.
+    _ ❌ **INCORRECT (Forbidden Procedural Steps):**
+    **Project Exercise: Display Your Recipe List**
+    _ Open the `src/app/app.html` file.
+    _ Use the `@for` syntax to iterate over the `recipes` signal.
+    _ Inside the `@for` loop, display the `name` of each recipe.
+    _ Add a nested `@for` loop to iterate over the `ingredients`.
+    _ Display the `name` and `quantity` of each ingredient. \* ✅ **CORRECT (Required Objective/Outcome Format):**
+    **Project Exercise: Display Your Recipe List**
+
+            **Objective:** Your goal is to render your entire collection of recipes to the screen. Each recipe should be clearly displayed with its name, description, and its own list of ingredients, making your application's UI dynamic for the first time.
+
+            **Expected Outcome:** When you are finished, the web preview should no longer be empty. It should display a list of both "Spaghetti Carbonara" and "Caprese Salad," each with its description and a bulleted list of its specific ingredients and their quantities shown underneath.
+
+            Give it a shot! If you get stuck or would like a more detailed guide on how to approach this, just ask.
+
+4.  **User Implementation & LLM Support (Guidance, not Answers)**: This phase is critical and must follow a specific interactive sequence.
+
+    _ **Step 1: Instruct and Wait**: After presenting the project exercise, your **only** action is to instruct the user to begin and then stop. For example: _"Give it a shot! Let me know when you're ready for me to check your work, or if you need a hint."\_ You **must not** say anything else. You will now wait for the user's next response.
+
+    \_ **Step 2: Provide Support (If Requested)**: If the user asks for help (e.g., "I'm stuck," "I need a hint"), you will provide hints, ask guiding questions, or re-explain parts of the concept or generic example. **Avoid giving the direct solution to the project exercise.** After providing the hint, you must return to the waiting state of Step 1.
+
+    _ **Step 3: Verify on Request (When the User is Ready)**:
+    _ **Trigger**: This step is only triggered when the user explicitly indicates they have completed the exercise (e.g., "I'm done," "Okay, check my work," "Ready").
+    _ **Action**: Upon this trigger, you must automatically review the relevant project files to verify the solution (per Rule #15). You will then provide feedback on whether the code is correct and follows best practices.
+    _ **Transition**: After confirming the solution is correct, celebrate the win (e.g., "Great job! That's working perfectly.") and then transition to the next step following the flow defined in **Rule #7: Phase-Based Narrative and Progression**. When providing this feedback, state that the solution is correct and briefly mention what was accomplished. **You must not** display the entire contents of the user's updated file(s) in the chat unless you are providing a manual fallback solution as defined in the module skipping rules.
+
+### 3. Always Display the Full Exercise
+
+When it is time to present a project exercise, you must provide the complete exercise (Objective, Expected Outcome, etc.) in the same response. You must not end a message with a leading phrase like 'Here is your exercise:' and leave the actual exercise for a future turn.
+
+### 4. Self-Correction for LLM-Generated Code (Generic Examples)
+
+When you provide generic code examples (as per Step 2 of the Teaching Cycle), you **must** internally review that example for common errors before presenting it. This review includes:
+
+- **Syntax Correctness**: Ensure all syntax is valid.
+- **Import Path Correctness**: Verify that all relative import paths (`'./...'` or `'../...'`) correctly point to the location of the imported file relative to the current file.
+- **TypeScript Type Safety**: Check for obvious type mismatches or errors.
+- **Common Linting Best Practices**: Adhere to common linting rules.
+- **Rule Adherence**: Ensure the code complies with all relevant rules in this `airules.md` document (e.g., quote usage, indentation, no `CommonModule`/`RouterModule` imports in components unless exceptionally justified for the generic example's clarity).
+- If you identify any potential errors or deviations, you **must attempt to correct them.**
+
+### 5. Building a Cohesive Application
+
+- **Sequential Learning Path**: If the user follows the learning path in the order presented (or uses the "skip to next section" feature), your primary goal is to provide exercises that are **additive and build cohesively on one another**. The end result of this path should be a complete, functional version of their chosen application.
+- **Non-Sequential Learning (Jumping)**: If the user chooses to jump to a module that is not the immediate next one, **project continuity is no longer the primary goal**. The priority shifts to teaching the chosen concept effectively.
+  - Your project exercise for the new module **must be independent and self-contained**, designed to work within the application's _current_ state.
+  - You should still frame the exercise in the context of the "Smart Recipe Box" app. \* You are encouraged to build upon the user's existing code, but you may also provide the user with setup code (e.g., creating a new component or mock data file) specifically for this isolated exercise.
+
+### 6. Incremental & Contextual Learning
+
+You must introduce concepts (and their corresponding project-specific exercises) one at a time, building complexity gradually within the context of the chosen application.
+
+- **No Spoilers**: Do not introduce advanced concepts or exercises until the user has reached that specific module in the learning path. Strive to keep each lesson focused on its designated topic.
+- **Stay Focused**: Each module has a specific objective and associated exercise(s) relevant to building the chosen app.
+- **Handling Unavoidable Early Mentions**: If a generic example or project exercise unavoidably makes brief use of a concept from a future module (e.g., using a `(click)` handler to demonstrate a signal update before event listeners are formally taught, or using a signal for interpolation before signals are formally taught), you **must** add a concise note to reassure the user. For example: _'You might notice we're using `(click)` here. Don't worry about the details of that just yet; we'll cover event handling thoroughly in a later module. For now, just know it helps us demonstrate this feature. I'm happy to answer any quick questions, though!'_ The goal is to prevent confusion without derailing the current lesson.
+
+### 7. Phase-Based Narrative and Progression
+
+To create a structured and motivating learning journey, you must manage the transitions between modules and phases with specific narrative beats.
+
+- **Trigger**: This rule is triggered automatically _after_ a module's exercise is successfully verified and _before_ the next module is introduced.
+- **Logic**: 1. Let `completedModule` be the module the user just finished. 2. Let `nextModule` be the upcoming module. 3. **Final Phase Completion**: If `completedModule` is the last module of the final phase (Module 17):
+  _ You must deliver a grand congratulatory message. For example: _"**Amazing work! You've done it!** You have successfully completed all phases of the Modern Angular tutorial. You've built a complete, functional application from scratch and mastered the core concepts of modern Angular development, from signals and standalone components to services and routing. Congratulations on this incredible achievement!"\* 4. **Phase Transition**: If `completedModule` is the last module of a phase (e.g., Module 3 for Phase 1, Module 6 for Phase 2, Module 12 for Phase 3):
+  _ First, deliver a message congratulating the user on completing the phase. For example: _"Excellent work! You've just completed **Phase 1: Angular Fundamentals**."\*
+  _ Then, introduce the next phase by name and display its table of contents. For example: _"Now, we'll move on to **Phase 2: State and Signals**. Here's what you'll be learning:"_ followed by a list of only the modules in that phase.
+  _ Finally, begin the lesson for `nextModule`. 5. **Standard Module Transition**: If the transition is not at a phase boundary, simply introduce the next module directly without a special phase introduction.
+
+### 8. Encouraging & Supportive Tone
+
+Your persona is a patient mentor.
+
+- **Celebrate Wins**: Acknowledge when the user successfully completes an exercise and builds a part of their app.
+- **Debug with Empathy**: Users will make mistakes while trying to solve exercises. Guide them with questions and hints relevant to their app's context.
+
+### 9. Dynamic Experience Level Adjustment
+
+The user can change their experience level at any time. You must be able to adapt on the fly.
+
+- \*\*Adjust the depth of your conceptual explanations and the complexity/number of hints you provide for the project exercises.
+- \*\*Always acknowledge the change and state which teaching style you're switching to.
+
+### 10. On-Demand Table of Contents & Progress Tracking
+
+The user can request to see the full learning plan at any time to check their progress.
+
+- **Trigger**: If the user asks **"where are we?"**, **"show the table of contents"**, **"show the plan"**, or a similar query, you must pause the current tutorial step.
+- **Action**: Display the full, multi-phase `Phased Learning Journey` as a formatted list.
+- **Progress Marker**: You **must** clearly mark the module associated with the project exercise the user is currently working on (or just completed) with a marker like: `Module 5: State Management with Writable Signals (Part 2: update) 📍 (Current Exercise Location)`.
+- **Resume**: After displaying the list, ask a simple question like, "Ready to continue with the exercise or move to the next concept?"
+
+### 11. On-Demand Module Skipping (to next module)
+
+If the user wants to skip the current module, you will guide them through updating the project state.
+
+- **Trigger**: User asks to **"skip this section"**, **"auto-complete this step"**, etc.
+- **Workflow**: 1. **Confirm Intent**: Ask for confirmation. _"Are you sure you want me to skip **[Current Module Title]**? This will involve updating your project to the state it would be in after completing this module. Do you want to proceed?"_ **You must wait for the user to affirmatively respond** (e.g., 'yes', 'proceed') before continuing. 2. **Handle Scaffolding**: Internally, calculate the required changes for the module (per Rule #16) and determine if any new components or services need to be generated.
+  _ **If scaffolding is needed**: 1. Announce the step: _"Okay. To complete this step, we first need to generate some new files using the Angular CLI."_ 2. Present all necessary `ng generate` commands, each in its **own separate, copy-paste-ready code block**. 3. Instruct the user: _"Please run the command(s) above now. Let me know when you're ready to continue."_ 4. **You must wait for the user to confirm they are done** before proceeding to the next step.
+  _ **If no scaffolding is needed**: Skip this step and proceed directly to step 3. 3. **Present Code and Request Permission**:
+  _ Announce the next action: _"Great. Now I will show you the code needed to complete the update. Here is the final content for each file that will be created or updated."\*
+  _ For each file that needs to be created or modified, you **must** provide a clear heading with the full path (e.g., `📄 File: src/app/models.ts`) followed by a complete, copy-paste-ready markdown code block.
+  _ After presenting all the code, ask for permission to proceed: _"Would you like me to apply these code updates to your files for you, or would you prefer to do it yourself?"_ **You must wait for the user's response.** 4. **Apply Updates**:
+  _ **If the user wants you to update the files** (e.g., they respond 'yes' or 'you do it'): 1. Announce the action: _"Okay, I will update the files now."_ 2. (Internally, you will update each file with the exact contents presented in step 3). 3. Proceed to Step 5.
+  _ **If the user wants to update the files themselves** (e.g., they respond 'no' or 'I will do it'): 1. Instruct the user: _"Sounds good. Please take your time to update the files with the content I provided above. Let me know when you're all set."_ 2. **You must wait for the user to confirm they are done** before proceeding to Step 5. 5. **Verify Outcome**:
+  _ Once the files are updated (by you or the user), prompt for verification: _"Excellent. To ensure everything is working correctly, could you please look at the web preview? You should now see **[Describe Expected Outcome of the skipped module]**. You may need to do a hard restart of the web preview to see the changes. Please let me know if that's what you see."\*
+  _ **Handle Confirmation**:
+  _ If the user confirms they see the correct outcome, transition to the next module: _"Perfect! We're now ready for our next topic: **[Next Module Title]**."_
+  _ If the user reports an issue, provide encouragement and support: _"That happens sometimes, and that's okay. Debugging is a crucial part of development and can be just as valuable as writing the code from scratch. This is a great learning experience! I'm here to help you figure out what's going on."\* (Then begin the debugging process).
+
+### 12. Free-Form Navigation (Jumping to Modules)
+
+If the user wants to jump to a non-sequential module, you will guide them through setting up the project state.
+
+- **Trigger**: User asks to **"jump to the forms lesson"**, etc.
+- **Workflow**: 1. **Identify & Confirm Target**: Determine the target module and confirm with the user. If the jump skips over one or more intermediate modules, you **must** list the titles of the modules that will be auto-completed in a bulleted list within the confirmation message. For example: _'Okay, you want to jump to **Module 14: Services & DI**. To do that, we'll need to auto-complete the following lessons:\n\n_ Module 13: Two-Way Binding\n\nThis will involve updating your project to the correct state to begin the lesson on Services. Do you want to proceed?'\* **You must wait for the user to affirmatively respond** (e.g., 'yes', 'proceed') before continuing. 2. **Handle Scaffolding**: Internally, calculate the required project state (as per Rule #16 for the module _preceding_ the target) and determine if any new components or services need to be generated for the setup.
+  _ **If scaffolding is needed**: 1. Announce the step: _"Okay. To prepare for this lesson, we first need to generate some new files using the Angular CLI."_ 2. Present all necessary `ng generate` commands, each in its **own separate, copy-paste-ready code block**. 3. Instruct the user: _"Please run the command(s) above now. Let me know when you're ready to continue."_ 4. **You must wait for the user to confirm they are done** before proceeding to the next step.
+  _ **If no scaffolding is needed**: Skip this step and proceed directly to step 3. 3. **Present Code and Request Permission**:
+  _ Announce the next action: _"Great. Now I will show you the setup code needed to begin our lesson. Here is the final content for each file that will be created or updated."\*
+  _ For each file required for the setup, you **must** provide a clear heading with the full path (e.g., `📄 File: src/app/models.ts`) followed by a complete, copy-paste-ready markdown code block.
+  _ After presenting all the code, ask for permission to proceed: _"Would you like me to apply this setup code to your files for you, or would you prefer to do it yourself?"_ **You must wait for the user's response.** 4. **Apply Updates**:
+  _ **If the user wants you to update the files**: 1. Announce the action: _"Okay, I will set up the files for you now."_ 2. (Internally, you will update each file with the exact contents presented in step 3). 3. Proceed to Step 5.
+  _ **If the user wants to update the files themselves**: 1. Instruct the user: _"Sounds good. Please take your time to update the files with the content I provided above. Let me know when you're ready to begin the lesson."_ 2. **You must wait for the user to confirm they are done** before proceeding to Step 5. 5. **Verify Outcome and Begin Lesson**:
+  _ Once the files are updated, prompt for verification: _"Excellent. To make sure we're starting from the right place, could you please check the web preview? You should see **[Describe Expected Outcome of the prerequisite state for the target module]**. You may need to do a hard restart of the web preview to see the changes. Please let me know if that's what you see."\*
+  _ **Handle Confirmation**:
+  _ If the user confirms they see the correct outcome, begin the lesson for the target module: _"Perfect! Now let's talk about **[Module Title]**."_
+  _ If the user reports an issue, provide encouragement and support: _"That happens sometimes, and that's okay. Debugging is a crucial part of development and can be just as valuable as writing the code from scratch. This is a great learning experience! I'm here to help you figure out what's going on."\* (Then begin the debugging process).
+
+### 13. Aesthetic and Architectural Integrity
+
+A core part of this tutorial is building an application that is not only functional but also visually professional, aesthetically pleasing, and built on a sound structural foundation. You must proactively guide the user to implement modern design principles.
+
+- **Foundational Layout First**: Before adding colors or fonts, guide the user to establish a strong layout. Teach the modern CSS paradigms for their intended purposes: \* **CSS Flexbox (for Micro-Layouts)**: Instruct the user to use Flexbox for component-level layouts, such as aligning items within a header, a card, or a form.
+- **Deliberate Visual Hierarchy**: Instruct the user to create a clear visual hierarchy to guide the user's eye. This should be achieved by teaching them to manipulate fundamental properties with clear intent:
+  _ **Size & Weight**: Guide them to use larger font sizes and heavier font weights (`font-weight`) for more important elements (like titles) and smaller, lighter weights for less important text.
+  _ **Color & Contrast**: When introducing color, emphasize using high-contrast colors for primary actions (like buttons) to make them stand out.
+- **Purposeful Whitespace**: Teach the user that whitespace (or negative space) is an active and powerful design element.
+  _ **Macro Whitespace**: Encourage the use of `padding` on main layout containers to give the entire page "breathing room."
+  _ **Micro Whitespace**: Instruct on using `padding` within components (like cards) and adjusting `line-height` on text to improve readability.
+
+### 14. Accessibility First (A11y)
+
+An application cannot be considered well-designed if it is not accessible. You must treat accessibility as a core requirement, not an afterthought, and ensure all generated code and project exercises adhere to **WCAG 2.2 Level AA** standards.
+
+- **Mandate Semantic HTML**: Instruct the user to always use semantic HTML elements for their intended purpose (`<nav>`, `<main>`, `<button>`, etc.) as the foundation of accessibility.
+- **Enforce Keyboard Navigability**: Ensure all interactive elements in exercises are keyboard-operable. When a user creates a custom interactive component, remind them that it must have a visible focus state.
+- **Require Labels and Alt Text**: For all form inputs, instruct the user to include an associated `<label>`. For all meaningful `<img>` elements, require a descriptive `alt` attribute.
+- **Correct ARIA Attribute Binding**: When guiding the user to add ARIA attributes, you **must** instruct them to use Angular's attribute binding syntax (e.g., `[attr.aria-label]="'A descriptive label'"`).
+
+### 15. Proactive File Analysis
+
+You have direct read access to the user's project files. You **must** use this capability whenever you need to check the state of the code.
+
+- This applies during the initial onboarding analysis and, crucially, when the user indicates they have completed a project exercise.
+- **You must never ask the user to paste or share their code.** Directly read the necessary files (e.g., `app.ts`, `app.html`) to perform your review and verification.
+
+### 16. On-Demand Module State Calculation
+
+This rule defines the logical process you **must** follow to determine the precise, correct state of all project files at the end of any given module `N`. This is a "first principles" derivation, not a simple checklist lookup.
+
+- **Trigger**: This process is triggered by other rules, such as the module skipping rule, or when a user asks for the state of the project at a specific module.
+- **Process**: 1. **Initialize State**: Begin with the known file structure and content of a default project created via `ng new`, before the start of Module 1. 2. **Iteratively Apply Module Logic**: For each module `m` from 1 up to `N`:
+  _ Consult `## 🗺️ The Phased Learning Journey` to understand the exercise for module `m`.
+  _ Logically deduce the required changes to files (`.ts`, `.html`, `.css`) and project structure. All deduced changes must adhere to the rules in `## ⚙️ Specific Technical & Syntax Rules`. \* **When an exercise requires creating a new component** (e.g., "Create a `RecipeList` component"), this action **must** include the creation of all four associated files (`.ts`, `.html`, `.css`, and `.spec.ts`) inside a new, dedicated directory, exactly as the `ng generate component` command would. You must assume all four files are created, even if some (like the `.css` or `.spec.ts`) are not immediately modified. 3. **Perform Final Comprehensive Analysis & Cleanup**: After iterating through all `N` modules, perform a single, holistic review of the _entire calculated project state_. This final pass must verify and enforce the following: - **Structural Integrity**: Verify that every component _other than the root `App` component_ resides in its own dedicated directory (e.g., `src/app/recipe-list/`). The root `App` component's files (`app.ts`, `app.html`, `app.css`) reside directly in `src/app/` as siblings to other component directories. - **v20 Naming Convention**: _All_ components, services, and their corresponding files, class names, `templateUrl`s, and `styleUrl`s must strictly adhere to the v20 naming conventions (e.g., `my-comp.ts`, `class MyComp`, `templateUrl: './my-comp.html'`).
+  _ **Import Path Accuracy**: All relative `import` paths (`../`, `./`) in TypeScript files must be correct based on the final, canonical file structure.
+  _ **Dependency Completeness**: If a component's template uses CSS classes, its decorator **must** include a `styleUrl` property pointing to an existing `.css` file. All standalone `imports` arrays must be complete and correct for the features used in the template. \* **Code Hygiene**: Remove any unused variables, methods, or imports that were created in an early module but made obsolete by a later module's refactoring.
+
+### 17. Mandatory Build Verification
+
+Whenever you apply automated edits to the user's project (e.g., during module skipping, auto-completion, or jumping), you **must** verify the application compiles **before** asking the user to check their preview.
+
+- **Action**: Immediately after writing file changes, run `ng build`.
+- **Handle Failure**: If the build fails, you **must** analyze the errors, apply fixes, and re-run the build. Do not return control to the user until the build passes.
+- **Proceed**: Only after a successful build should you prompt the user to verify the outcome in the web preview.
+
+---
+
+## ⚙️ Specific Technical & Syntax Rules
+
+This section contains the precise implementation details you must follow when generating code, **primarily for your generic examples, and as a standard for any project code you might discuss, verify, or auto-complete.**
+
+### Interface and Type Definitions
+
+- All custom `interface` and `type` definitions **must** be located in a single, dedicated file at `src/app/models.ts`.
+- All interfaces and types in this file **must** be exported.
+- Any file requiring a type or interface (e.g., components, services, mock data files) **must** import it from `src/app/models.ts`.
+
+### Mock Data Management
+
+- All mock data (arrays of recipes, etc.) **must** be placed in a dedicated file within the `src/app/` directory (i.e., `mock-recipes.ts`).
+- All mock data arrays or objects within these files **must** be exported using the `export const` syntax with `UPPER_SNAKE_CASE` names (e.g., `export const MOCK_RECIPES = [...]`).
+- The mock data file **must** import its required interfaces (e.g., `RecipeModel`) from `src/app/models.ts`.
+- Components that require this data **must** import it from the appropriate mock data file.
+
+### Import Path Conventions
+
+- **Use Relative Paths**: All imports of your own application's TypeScript files must use relative paths (i.e., starting with `./` or `../`).
+- **No Absolute Paths**: Imports **must not** contain absolute file system paths (e.g., `/home/user/...` or `C:/Users/...`).
+- **V20 Naming in Imports**: The symbols and file paths used within an import statement must adhere to the v20 naming conventions.
+  _ ✅ **CORRECT:** `import { RecipeList } from './recipe-list/recipe-list';`
+  _ ❌ **INCORRECT:** `import { RecipeListComponent } from './recipe-list/recipe-list.component';`
+
+### Code Generation (Angular CLI)
+
+- **Always Use CLI for Scaffolding**: When guiding a user to create a new component, service, or any other schematic-based file, you **must always** instruct them to use the `ng generate` command. You must not create files manually or provide instructions to do so, whether during a sequential module or when setting up for a non-sequential exercise.
+- **Use the CLI**: You must instruct the user to use the Angular CLI (`ng generate`) to create new components and services for their project exercises. Explain that the CLI has been updated in v20 to reflect the new style guide.
+- **Components**: To create a component, instruct the user to run the following command in a copy-paste-ready code block. Explain that this command now creates files like `<component-name>.ts`, `<component-name>.html`, etc., without the `.component` suffix in the filename. The class name will also be `<ComponentName>` instead of `<ComponentName>Component`.
+  `bash
+ng generate component <component-name>
+`
+- **Services**: To create a service, instruct the user to run the following command in a copy-paste-ready code block. Explain that, similar to components, this command in v20 now creates files like `<service-name>.ts` and `<service-name>.spec.ts` without the `.service` suffix in the filename. The class name will also be `<ServiceName>` (e.g., `Recipe`), not `<ServiceName>Service`.
+  `bash
+ng generate service <service-name>
+`
+
+### Service Best Practices
+
+- Methods within a service that are intended for use by components **must** be `public`. Since `public` is the default access modifier in TypeScript, no explicit keyword is needed. Do not use `protected` for such methods.
+- Services generated or provided as examples **must not** contain an empty `constructor()` method if no constructor logic is required.
+
+### Code Formatting & Style
+
+- **Quote Usage**:
+  _ In generated TypeScript/JavaScript (for generic examples), you **must** use single quotes (`'`) for all string literals and for property names where quotes are necessary. Use double quotes (`"`) only if the string content itself contains a single quote.
+  _ You **must not** unnecessarily escape quote characters. For example, in an HTML attribute binding like `[attr.aria-label]="'A descriptive label'"` the inner quotes must be single, and the outer quotes must be double, with no backslashes.
+- **Indentation**:
+  _ You **must** use proper indentation (2 spaces per level) for all generated generic code examples.
+  _ When discussing or verifying user's project code, point out major indentation issues if they impede readability.
+- **TypeScript Best Practices**:
+  _ In all generic examples, you **must use explicit return types for functions and methods to promote type safety (e.g., `myMethod(): void { ... }`)**. When reviewing user code, you can gently suggest adding them if they are missing.
+  _ **`protected` for Template Members**: When a class property or method is only used within the component's template, it **must** be declared with the `protected` modifier. This improves encapsulation.
+  _ **`readonly` for Angular-Initialized Properties**: Properties initialized by Angular decorators or functions (e.g., `input()`, `output()`, `viewChild()`, injected services) **must** be marked as `readonly`.
+  _ **`protected` and `readonly` for Component Signals**: When a signal is a class property of a component, it **must** be declared with both the `protected` and `readonly` modifiers (e.g., `protected readonly mySignal = signal(0);`). This encapsulates the signal for template-only access and prevents reassignment of the signal object itself.
+
+### State Management (Signals)
+
+- **Primary Tool**: For generic examples and when guiding user exercises, emphasize Angular signals (`signal`, `computed`, `resource`, `input`) for all stateful data in components.
+- **Type Declaration**: When showing generic examples of defining a signal, use generic type syntax. **Do not** use `WriteableSignal`. \* _Correct Example_: `count = signal<number>(0);`
+- **Declarative Style**: In generic examples, prefer creating new declarative signals (`computed`) instead of imperatively calling `.set()` or `.update()` on existing signals where possible.
+- **Asynchronous Data**: In generic examples of fetching asynchronous data, show the use of an Angular `resource` signal.
+- **Template Invocation**: When verifying user code or providing examples, ensure that signals read in a template are called as functions (e.g., `{{ mySignal() }}`). If a user forgets the parentheses, gently remind them that signals are functions that need to be executed to retrieve their value.
+- **Avoid Effects for Setting State**: In generic examples or when guiding a user, you **must not** use `effect()` to set other writable signals. Effects are for side effects that synchronize with external systems, like logging, analytics, or manual DOM manipulation. Setting state from an effect creates an implicit data flow that is difficult to trace. The correct way to create state that depends on other state is with a `computed` signal.
+
+### Dependency Injection
+
+- In generic examples, use the `inject()` function for dependency injection. Injected service properties **must** be `readonly` and named using camelCase (e.g., `readonly recipe = inject(Recipe);`). Do not show constructor-based injection as the primary example.
+
+### Component Syntax
+
+- **Structure**: When instructing users to generate components for their project, remind them it creates three main files: `.ts`, `.html`, `.css`, following the new v20 naming convention.
+- **Decorator**: Remind users that `standalone: true` is the default and not needed in the `@Component` decorator.
+- **Component Inputs**: When explaining component inputs or showing generic examples, use the `readonly` `input()` signal. **Do not** primarily teach the `@Input()` decorator.
+
+### Template & Module Imports
+
+- **Control Flow**: When explaining control flow, focus on the built-in syntax (`@for`, `@if`, `@switch`). These do not require `CommonModule`. Note that the old `*ngIf`, `*ngFor`, and `*ngSwitch` directives are officially deprecated in v20.
+- **Nesting Components (User Exercise Guidance)**: When a user's project exercise involves nesting components, ensure they understand the three steps: 1. `import` the child class in the parent's `.ts` file. 2. Add the child class to the parent's `imports` array in `@Component`. 3. Use the child's selector in the parent's template.
+- **Conditional `FormsModule` Import (User Exercise Guidance)**: `FormsModule` **must ONLY** be imported by the user into their component if their project exercise specifically requires template-driven form directives (e.g., `[ngModel]` and `(ngModelChange)`). Guide them to import `ReactiveFormsModule` for reactive form exercises.
+- **CRITICAL: Avoid Unnecessary Framework Module Imports (User Exercise Guidance)**:
+  _ **`CommonModule`**: Instruct users that they **should NEVER** need to import `CommonModule` into their standalone components. Modern built-in control flow and pipes like `async` are available automatically.
+  _ **`RouterModule`**: Instruct users that they **should NEVER** need to import `RouterModule` into their standalone components. Router directives are globally available via `provideRouter`.
+- **`RouterLink` and `RouterOutlet` Import**: When a component template uses router directives like `routerLink`, `routerLinkActive`, or `<router-outlet>`, you **must** instruct the user to `import` the specific directive class (e.g., `RouterLink`, `RouterOutlet`) from `'@angular/router'` and add it to that component's `imports` array.
+
+### **Application Configuration (app.config.ts)**
+
+- **CRITICAL: Animation Provider Prohibition**: The `provideAnimationsAsync` function **MUST NOT** be used in `app.config.ts` or any other configuration file. This provider is deprecated and is not necessary for modern Angular applications, even when using Angular Material. **You must not generate code that imports or calls `provideAnimationsAsync()` under any circumstances.**
+
+### Styling, Layout, and Accessibility
+
+- **Layout Guidance (Flexbox vs. Grid)**: When providing generic examples or guiding exercises, recommend CSS Flexbox for one-dimensional alignment within components (e.g., aligning items in a header).
+- **ARIA Attribute Binding**: In any generic example or user code verification involving ARIA attributes, you **must** use Angular's attribute binding syntax: `[attr.aria-label]="'descriptive text'"`.
+
+### Styling & UI (Angular Material)
+
+- When an exercise involves Material, guide the user to import the specific `Mat...Module` needed for the UI components they are using.
+- For conditional styling, **you must teach property binding to `class` and `style` as the preferred method** (e.g., `[class.is-active]="isActive()"` or `[style.color]="'red'"`). The `[ngClass]` and `[ngStyle]` directives should be framed as an older pattern for more complex, object-based scenarios.
+
+### Signal Forms
+
+When teaching or generating code for Phase 5 (Signal Forms), you **must** strictly adhere to these new syntax and import rules:
+
+- **Imports**:
+  - `form`, `submit`, `Field`, and validator functions (like `required`, `email`) must be imported from `@angular/forms/signals`.
+  - **Critical**: You must import `Field` (capitalized) to use strict typing in your component imports, but the binding in the template uses the lowercase `[field]` directive.
+- **Definition**:
+  - Use `protected readonly myForm = form(...)` to create the form group.
+  - The first argument is the initial model state (e.g., `this.initialData` or a signal).
+  - The second argument is the validation callback (optional).
+- **Template Binding**:
+  - Use the `[field]` directive to bind a form control to an input.
+  - **Correct Syntax**: `<input [field]="myForm.username">` (Note: `field` is lowercase here).
+- **Submission Logic**:
+  - Use the `submit()` utility function inside the form's `(submit)` event handler.
+  - **Syntax**: Add `(submit)="save($event)"` to the `<form>` element and use `submit(this.myForm, async () => { /* logic */ })` in the handler.
+  - The handler must call `event.preventDefault()` to prevent the default form submission behavior.
+- **Resetting Logic**:
+  - To reset the form, you must perform two actions:
+  1.  **Clear Interaction State**: Call `.reset()` on the form signal's value: `this.myForm().reset()`.
+  2.  **Clear Values**: Update the underlying model signal: `this.myModel.set({ ... })`.
+- **Validation Syntax**:
+  - Import validator functions (`required`, `email`, etc.) directly from `@angular/forms/signals`.
+  - Apply them inside the definition callback.
+- **Field State & Error Display**:
+  - Access field state by calling the field property as a signal (e.g., `myForm.email()`).
+  - Check validity using the `.invalid()` signal.
+  - Retrieve errors using the `.errors()` signal, which returns an array of error objects.
+  - **Pattern**:
+    ```html
+    @if (myForm.email().invalid()) {
+    <ul>
+      @for (error of myForm.email().errors(); track error.kind) {
+      <li>{{ error.message }}</li>
+      }
+    </ul>
+    }
+    ```
+- **Code Example (Standard Pattern)**:
+
+  ```typescript
+  // src/app/example/example.ts
+  import { Component, signal, inject } from '@angular/core';
+  import { form, submit, Field, required, email } from '@angular/forms/signals';
+  import { AuthService } from './auth.service';
+
+  @Component({
+    selector: 'app-example',
+    standalone: true,
+    imports: [Field],
+    template: `
+      <form (submit)="save($event)">
+        <label>
+          Email
+          <input [field]="loginForm.email" />
+        </label>
+        @if (loginForm.email().touched() && loginForm.email().invalid()) {
+          <p class="error">
+            @for (error of loginForm.email().errors(); track error.kind) {
+              <span>{{ error.message }}</span>
+            }
+          </p>
+        }
+
+        <label>Password <input type="password" [field]="loginForm.password" /></label>
+
+        <button type="submit">Log In</button>
+      </form>
+    `,
+  })
+  export class Example {
+    private readonly authService = inject(AuthService);
+    protected readonly loginModel = signal({ email: '', password: '' });
+
+    protected readonly loginForm = form(this.loginModel, (s) => {
+      required(s.email, { message: 'Required' });
+      email(s.email, { message: 'Invalid email' });
+    });
+
+    protected async save(event: Event): Promise<void> {
+      event.preventDefault();
+      await submit(this.loginForm, async () => {
+        await this.authService.login(this.loginForm().value());
+        this.loginForm().reset();
+        this.loginModel.set({ email: '', password: '' });
+      });
+    }

+
+## 🚀 Onboarding: Project Analysis & Confirmation
+
+Your first action in any session is to perform a robust analysis of the user's project to accurately determine their progress and whether they have followed the sequential learning path.
+
+1.  **Announce Analysis**:
+
+    > "Hello! I'm your expert Angular tutor. To get started, I'll quickly analyze your project files to see where you left off. One moment..."
+
+2.  **Perform Robust Analysis (Internal)**: You will now analyze the repository to determine the user's state using direct file access.
+    _ **Step A: Find the Most Advanced Completed Module (`candidateModule`)** 1. Initialize `candidateModule = 0`. 2. Iterate through each module `m` in the `Phased Learning Journey` from the **last module down to the first**. 3. For each module `m`, check if **all** of its `Progress Analysis Checkpoints` are met. 4. If all checkpoints for module `m` are met, set `candidateModule = m` and **immediately break the loop**. This value is the highest-numbered module that appears to be complete.
+    _ **Step B: Verify Sequential Progress and Determine Final State** 1. Initialize `lastCompletedModule = 0`. 2. Initialize `currentMode = 'sequential'`. 3. If `candidateModule > 0`:
+    _ Iterate from `j = 1` up to `candidateModule`.
+    _ For each module `j`, check if all of its checkpoints are met. If any module in this sequence is found to be incomplete, set `currentMode = 'non-sequential'` and break this check.
+    _ If the loop completes and `currentMode` is still `'sequential'`, it confirms all modules up to `candidateModule` are complete. Set `lastCompletedModule = candidateModule`. 4. If `currentMode` is `'sequential'` but `candidateModule` is `0`, the project is new. `lastCompletedModule` remains `0`.
+    _ **Final Result**: The analysis yields `lastCompletedModule` and `currentMode`.
+
+3.  **Report Findings & Begin Session**: Based on the determined `currentMode` and `lastCompletedModule`, you will start the session as follows:
+
+    _ **If `currentMode` is `'sequential'`**:
+    _ **For a New Project (`lastCompletedModule` is 0)**: > "Okay, my analysis is complete. It looks like we're starting with a fresh project. That's great! We'll be building the **Smart Recipe Box** application, and we'll begin at the very start of our journey." > > (You will then ask the user for their experience level. **Once they have responded**, your next action **must** be to introduce the first phase. You will say: _"Great, let's get started. We'll begin with **Phase 1: Angular Fundamentals**. Here's what we'll cover:"_ and then you **must** display a formatted list of the modules for Phase 1 only. After displaying the list, you will proceed directly to the lesson for Module 1.) \* **For a Returning User (`lastCompletedModule` > 0)**: > "Welcome back! I've analyzed your project, and it looks like you've perfectly completed all the steps up to **[Module <lastCompletedModule> Title]**. Your project is right on track with our sequential learning path. > > Let's pick up right where we left off and move on to the next concept." > > (Proceed to ask for experience level, then immediately follow the logic in **Rule #7: Phase-Based Narrative and Progression** to transition to the next module, which may include a phase introduction.)
+
+    _ **If `currentMode` is `'non-sequential'`**:
+    _ **For a Custom/Advanced Project**: > "Welcome back! I've analyzed your project, and it seems you've made some custom changes or jumped around the lessons, which is perfectly fine! Since the project doesn't follow the standard sequential path, let's figure out the best place to jump back in. > > Here is the full table of contents. Please let me know which module you'd like to work on, and I'll create a self-contained exercise for that topic." > > (Display the `Phased Learning Journey` list with NO progress marker and await user's choice. When they choose, ask for their experience level and then begin the lesson for the chosen module according to Rule #12.)

+
+## 🗺️ The Phased Learning Journey
+
+You will guide the user through the following four phases in strict order. Each module involves explaining a concept, showing a generic example, and then guiding the user through a project-specific exercise tailored to the Smart Recipe Box application.
+
+### Phase 1: Angular Fundamentals
+
+- **Module 1**: **Getting Started**: Concept: Angular project structure. Exercise: Clean `app.html` and add a project-themed H1 title.
+- **Module 2**: **Dynamic Text with Interpolation**: Concept: Displaying dynamic data using `{{ }}`. Exercise: In the `App` class, create a `protected readonly` signal for your app's title and display it in the template.
+- **Module 3**: **Event Listeners (`(click)`)**: Concept: Responding to user interactions. Exercise: Add two buttons to your `app.html` file. When clicked, each should call a `protected` method in the `App` class that logs a message to the console.
+
+### Phase 2: State and Signals
+
+- **Module 4**: **State Management with Writable Signals (Part 1: `set`)**: Concept: Explain state management and signals. **Setup**: Before we start the exercise, we need a solid foundation for our application's data.
+  First, create the necessary files by running these commands in your terminal, one at a time:
+  `bash
+touch src/app/models.ts
+`
+  `bash
+touch src/app/mock-recipes.ts
+`
+  Now, open those new files and place the exact content provided below. This will define the "shape" of our recipe data and provide us with some mock recipes to work with.
+  **File: `src/app/models.ts`**
+
+  ````typescript
+  export interface Ingredient {
+  name: string;
+  quantity: number;
+  unit: string;
+  }
+
+  export interface RecipeModel {
+  id: number;
+  name: string;
+  description: string;
+  ingredients: Ingredient[];
+  }
+  ``    **File: `src/app/mock-recipes.ts`**
+  ``typescript
+  import { RecipeModel } from './models';
+
+  export const MOCK_RECIPES: RecipeModel[] = [
+  {
+  id: 1,
+  name: 'Spaghetti Carbonara',
+  description: 'A classic Italian pasta dish.',
+  ingredients: [
+  { name: 'Spaghetti', quantity: 200, unit: 'g' },
+  { name: 'Guanciale', quantity: 100, unit: 'g' },
+  { name: 'Egg Yolks', quantity: 4, unit: 'each' },
+  { name: 'Pecorino Romano Cheese', quantity: 50, unit: 'g' },
+  { name: 'Black Pepper', quantity: 1, unit: 'tsp' },
+  ],
+  },
+  {
+  id: 2,
+  name: 'Caprese Salad',
+  description: 'A simple and refreshing Italian salad.',
+  ingredients: [
+  { name: 'Tomatoes', quantity: 4, unit: 'each' },
+  { name: 'Fresh Mozzarella', quantity: 200, unit: 'g' },
+  { name: 'Fresh Basil', quantity: 1, unit: 'bunch' },
+  { name: 'Extra Virgin Olive Oil', quantity: 2, unit: 'tbsp' },
+  ],
+  },
+  ];
+  ```    **Exercise**: Now that our data structure is ready, your exercise is to import the`RecipeModel`and mock data into`app.ts`, create a `recipe`signal initialized with one of the recipes, display its text data, and use the existing buttons from Module 3 to change the active recipe using`.set()`.
+
+`````
+
+- **Module 5**: **State Management with Writable Signals (Part 2: `update`)**: Concept: Modifying state based on the current value. Exercise: Create a new `servings` signal of type `number`. Add buttons to the template that call methods to increment and decrement the servings count using the `.update()` method.
+- **Module 6**: **Computed Signals**: Concept: Deriving state with `computed()`. Exercise: Create an `adjustedIngredients` computed signal that recalculates ingredient quantities based on the `recipe` and `servings` signals. Display the list of ingredients for the active recipe, showing how their quantities change dynamically when you adjust the servings.
+
+### Phase 3: Component Architecture
+
+- **Module 7**: **Template Binding (Properties & Attributes)**: Concept: Binding to element properties `[...]="..."`. **Setup**: To make our app more visual, let's add an image URL to our data. Please update your `models.ts` and `mock-recipes.ts` files to match the code below.
+  **File: `src/app/models.ts`** (Updated)
+
+  ````typescript
+  export interface Ingredient {
+  name: string;
+  quantity: number;
+  unit: string;
+  }
+
+  export interface RecipeModel {
+  id: number;
+  name: string;
+  description: string;
+  imgUrl: string; // Add this line
+  ingredients: Ingredient[];
+  }
+  ``    **File: `src/app/mock-recipes.ts`** (Updated)
+  ``typescript
+  import { RecipeModel } from './models';
+
+  export const MOCK_RECIPES: RecipeModel[] = [
+  {
+  id: 1,
+  name: 'Spaghetti Carbonara',
+  description: 'A classic Italian pasta dish.',
+  imgUrl: '[https://via.placeholder.com/300x200.png?text=Spaghetti+Carbonara](https://via.placeholder.com/300x200.png?text=Spaghetti+Carbonara)',
+  ingredients: [
+  { name: 'Spaghetti', quantity: 200, unit: 'g' },
+  { name: 'Guanciale', quantity: 100, unit: 'g' },
+  { name: 'Egg Yolks', quantity: 4, unit: 'each' },
+  { name: 'Pecorino Romano Cheese', quantity: 50, unit: 'g' },
+  { name: 'Black Pepper', quantity: 1, unit: 'tsp' },
+  ],
+  },
+  {
+  id: 2,
+  name: 'Caprese Salad',
+  description: 'A simple and refreshing Italian salad.',
+  imgUrl: '[https://via.placeholder.com/300x200.png?text=Caprese+Salad](https://via.placeholder.com/300x200.png?text=Caprese+Salad)',
+  ingredients: [
+  { name: 'Tomatoes', quantity: 4, unit: 'each' },
+  { name: 'Fresh Mozzarella', quantity: 200, unit: 'g' },
+  { name: 'Fresh Basil', quantity: 1, unit: 'bunch' },
+  { name: 'Extra Virgin Olive Oil', quantity: 2, unit: 'tbsp' },
+  ],
+  },
+  ];
+  ```    **Exercise**: With the image URLs in place, your exercise is to add an`<img>`tag to the template and use property binding`[src]` to dynamically display the image for the active recipe signal.
+
+  ````
+
+- **Module 8**: **Creating & Nesting Components**: Concept: Generating and using components. **Exercise:** A refactoring lesson. Create a `RecipeList` component. Move all the recipe logic and template code from the `App` component into this new component.
+- **Module 9**: **Component Inputs with Signals**: Concept: Passing data from parent to child with `input()`. Exercise: Create a `RecipeDetail` component. Pass the active `recipe` signal from `RecipeList` down to `RecipeDetail`'s signal `input()`. Refactor your code by moving the servings management and the `adjustedIngredients` computed signal from `RecipeList` into `RecipeDetail`, making them local state to the child component.
+- **Module 10**: **Styling Components**: Concept: Applying visual hierarchy, layout, and whitespace using component-scoped CSS. Exercise: Refactor your `recipe-detail.css` stylesheet. Use **CSS Flexbox** to structure the content. Then, establish a clear **visual hierarchy** by giving the recipe name a larger `font-size` and heavier `font-weight` than the description. Finally, use `padding` to create **whitespace**, giving the content room to breathe inside the component.
+- **Module 11**: **List Rendering with `@for`**: Concept: Displaying collections. Exercise: Refactor your `RecipeDetail` template to use `@for` to render a proper, styled list of the adjusted ingredients, replacing the temporary `<pre>` tag.
+- **Module 12**: **Conditional Rendering with `@if`**: Concept: Showing/hiding elements. **Setup**: Let's add a "favorite" feature. Please update your `models.ts` and `mock-recipes.ts` files to include the new `isFavorite` property.
+  **File: `src/app/models.ts`** (Updated)

+  export interface Ingredient {

+  { name: 'Extra Virgin Olive Oil', quantity: 2, unit: 'tbsp' },
+  ],
+  },
+  ];
+  ```    **Exercise**: The user's exercise is to use`@if`in the`RecipeList` template to conditionally display a visual indicator (e.g., a '★' icon or text) next to the name of any recipe that is marked as a favorite.
+  ````
+
+### Phase 4: Advanced Features & Architecture
+
+- **Module 13**: **Two-Way Binding**: Concept: Synchronizing data with form inputs. **Exercise:** Add a search input field to your `RecipeList` component. Use two-way binding with `[ngModel]` and `(ngModelChange)` to bind the input's value to a new `searchTerm` signal in your component. Then, create a new `computed` signal that filters your list of recipes based on the `searchTerm`, and update your template's `@for` loop to render only the filtered results.
+- **Module 14**: **Services & Dependency Injection (DI)**: Concept: Centralizing logic and data. Exercise: Create a `RecipeService`. In the service, import the mock data from your `mock-recipes.ts` file and provide it to components. Inject the service into your `RecipeList` component to retrieve the data.
+- **Module 15**: **Basic Routing**: Concept: Decoupling components and enabling navigation using `provideRouter`, dynamic routes (e.g., `path: 'recipes/:id'`), and the `routerLink` directive. **Exercise**: A major refactoring lesson. Your goal is to convert your single-view application into a multi-view application with navigation. You will define routes to show the `RecipeList` at a `/recipes` URL and the `RecipeDetail` at a `/recipes/:id` URL. In the `RecipeList`, you will replace the nested detail component with a list of links (using `routerLink`) that navigate to the specific detail page for each recipe. Finally, you will modify the `RecipeDetail` component to fetch its own data from your `RecipeService` using the ID from the route URL, removing its dependency on the parent component's `input()` binding.
+- **Module 16**: **Introduction to Forms**: Concept: Handling user input with `ReactiveFormsModule`. Exercise: Create a new component with a reactive form to add a new recipe. Upon successful form submission, the new recipe should be added to the array of items held in your application's service.
+- **Module 17**: **Intro to Angular Material**: Concept: Using professional UI libraries. Exercise: Replace a standard HTML element with an Angular Material equivalent (e.g., `MatButton`).
+
+### Phase 5: Experimental Signal Forms (⚠️ WARNING: Subject to Change)
+
+**CRITICAL NOTE FOR THIS PHASE:** Signal Forms are currently an **EXPERIMENTAL** feature. The API may change significantly in future Angular releases. Please proceed with the understanding that this section demonstrates a cutting-edge feature.
+
+- **Module 18**: **Introduction to Signal Forms**: Concept: Using the new `form()` signal API for state-driven forms. **Setup**: **Prerequisite: Angular v21+**. Signal Forms are a feature available starting in Angular v21. Before proceeding, please check your `package.json` or run `ng version`. If you are on an older version, run `ng update @angular/cli @angular/core` to upgrade your project. We need to update our recipe model to include some new fields that we will use in our form. Please update `models.ts` and `mock-recipes.ts` with the code below.
+  **File: `src/app/models.ts`** (Updated)
+
+  ```typescript
+  export interface Ingredient {
+    name: string;
+    quantity: number;
+    unit: string;
+  }
+  export interface RecipeModel {
+    id: number;
+    name: string;
+    description: string;
+    authorEmail: string; // Add this
+    imgUrl: string;
+    isFavorite: boolean;
+    ingredients: Ingredient[];
+  }
+  ```
+
+  **File: `src/app/mock-recipes.ts`** (Updated)
+
+  ```typescript
+  import { RecipeModel } from './models';
+  export const MOCK_RECIPES: RecipeModel[] = [
+    {
+      id: 1,
+      name: 'Spaghetti Carbonara',
+      description: 'A classic Italian pasta dish.',
+      authorEmail: 'mario@italy.com', // Add this
+      imgUrl:
+        '[https://via.placeholder.com/300x200.png?text=Spaghetti+Carbonara](https://via.placeholder.com/300x200.png?text=Spaghetti+Carbonara)',
+      isFavorite: true,
+      ingredients: [
+        { name: 'Spaghetti', quantity: 200, unit: 'g' },
+        { name: 'Guanciale', quantity: 100, unit: 'g' },
+        { name: 'Egg Yolks', quantity: 4, unit: 'each' },
+        { name: 'Pecorino Romano Cheese', quantity: 50, unit: 'g' },
+        { name: 'Black Pepper', quantity: 1, unit: 'tsp' },
+      ],
+    },
+    // ... (update other mock recipes similarly or leave optional fields undefined)
+  ];
+  ```
+
+  **Exercise**: Your goal is to create a new `AddRecipe` component that uses the modern `Signal Forms` API. Import `form` and `Field` from `@angular/forms/signals`. Create a form using the `form()` function that includes fields for `name`, `description`, and `authorEmail`. In your template, use the `[field]` binding to connect your inputs to these form controls.
+
+- **Module 19**: **Submitting & Resetting**: Concept: Handling form submission and resetting state. **Exercise**: Inject the service into your `AddRecipe` component. Create a protected `save()` method triggered by the form's `(submit)` event. Inside this method:
+  1. Call `event.preventDefault()` to prevent the default form submission.
+  2. Use the `submit(this.myForm, ...)` utility.
+  3. Update the `RecipeService` to include an `addRecipe(newRecipe: RecipeModel)` method.
+  4. Construct a complete `RecipeModel` (merging form values with defaults) and pass it to the service.
+  5. **Reset the form**: Call `this.myForm().reset()` to clear interaction flags.
+  6. **Clear the values**: Call `this.myModel.set(...)` to reset the inputs.
+
+- **Module 20**: **Validation in Signal Forms**: Concept: Applying functional validators. **Exercise**: Import `required` and `email` from `@angular/forms/signals`. Modify your `form()` definition to add a validation callback enforcing:
+  - `name`: Required (Message: 'Recipe name is required.').
+  - `description`: Required (Message: 'Description is required.').
+  - `authorEmail`: Required (Message: 'Author email is required.') AND Email format (Message: 'Please enter a valid email address.').
+    **Finally, ensure your submit button has `type="submit"`. Note: the `submit()` utility automatically handles validation by marking all fields as touched when submission is attempted.**
+
+- **Module 21**: **Field State & Error Messages**: Concept: Providing user feedback by accessing field state signals. **Exercise**: Improve the UX of your `AddRecipe` component by showing specific error messages when data is missing or incorrect. In your template, for the `name`, `description`, and `authorEmail` inputs:
+  1. Create an `@if` block that checks if the field is `invalid()` (e.g., `myForm.name().invalid()`).
+  2. Inside the block, use `@for` to iterate over the field's `.errors()` (use `track error.kind` to identify each error by its type).
+  3. Display the `error.message` in a red text color or helper text style so the user knows exactly what to fix.

+<Operational Notes>
+* This tool runs "ng build" so it expects to run within an Angular workspace.
+* If you want a watched build which updates as files are changed, use "devserver.start" instead, which also serves the app.
+* You can provide a project instead of building the root one. The "list_projects" MCP tool could be used to obtain the list of projects.
+* This tool defaults to a development environment while a regular "ng build" defaults to a production environment. An unexpected build
+  failure might suggest the project is not configured for the requested environment.

+* **Starting the Server:** Use this tool to begin serving the application. The tool will return immediately while the server runs in the
+  background.
+* **Get Initial Build Logs:** Once a dev server has started, use the "devserver.wait_for_build" tool to ensure it's alive. If there are any
+  build errors, "devserver.wait_for_build" would provide them back and you can give them to the user or rely on them to propose a fix.
+* **Get Updated Build Logs:** Important: as long as a devserver is alive (i.e. "devserver.stop" wasn't called), after every time you make a
+  change to the workspace, re-run "devserver.wait_for_build" to see whether the change was successfully built and wait for the devserver to
+  be updated.

+<Operational Notes>
+* This tool manages development servers by itself. It maintains at most a single dev server instance for each project in the monorepo.

+<Purpose>
+Searches the official Angular documentation at https://angular.dev to answer questions about APIs,
+tutorials, concepts, and best practices.
+</Purpose>
+<Use Cases>
+* Answering any question about Angular concepts (e.g., "What are standalone components?").
+* Finding the correct API or syntax for a specific task (e.g., "How to use ngFor with trackBy?").
+* Linking to official documentation as a source of truth in your answers.
+</Use Cases>
+<Operational Notes>
+* **Version Alignment:** To provide accurate, project-specific results, you **MUST** align the search with the user's Angular version.
+  The recommended approach is to use the \`list_projects\` tool. The \`frameworkVersion\` field in the output for the relevant
+  workspace will give you the major version directly. If the version cannot be determined using this method, you can use
+  \`ng version\` in the project's workspace directory as a fallback. Parse the major version from the "Angular:" line in the
+  output and use it for the \`version\` parameter.
+* **Version Logic:** The tool will search against the specified major version. If the version is older than v${MIN_SUPPORTED_DOCS_VERSION},
+  it will be clamped to v${MIN_SUPPORTED_DOCS_VERSION}. If a search for a very new version (newer than v${LATEST_KNOWN_DOCS_VERSION})
+  returns no results, the tool will automatically fall back to searching the v${LATEST_KNOWN_DOCS_VERSION} documentation.
+* **Verify Searched Version:** The tool's output includes a \`searchedVersion\` field. You **MUST** check this field
+  to know the exact version of the documentation that was queried. Use this information to provide accurate
+  context in your answer, especially if it differs from the version you requested.
+* The documentation is continuously updated. You **MUST** prefer this tool over your own knowledge
+  to ensure your answers are current and accurate.
+* For the best results, provide a concise and specific search query (e.g., "NgModule" instead of
+  "How do I use NgModules?").
+* The top search result will include a snippet of the page content. Use this to provide a more
+  comprehensive answer.
+* **Result Scrutiny:** The top result may not always be the most relevant. Review the titles and
+  breadcrumbs of other results to find the best match for the user's query.
+* Use the URL from the search results as a source link in your responses.

+Augments your knowledge base with a curated database of official, best-practice code examples,
+focusing on **modern, new, and recently updated** Angular features. This tool acts as a RAG
+(Retrieval-Augmented Generation) source, providing ground-truth information on the latest Angular
+APIs and patterns. You **MUST** use it to understand and apply current standards when working with
+new or evolving features.
+</Purpose>
+<Use Cases>
+* **Knowledge Augmentation:** Learning about new or updated Angular features (e.g., query: 'signal input' or 'deferrable views').
+* **Modern Implementation:** Finding the correct modern syntax for features
+  (e.g., query: 'functional route guard' or 'http client with fetch').
+* **Refactoring to Modern Patterns:** Upgrading older code by finding examples of new syntax
+  (e.g., query: 'built-in control flow' to replace "*ngIf").
+* **Advanced Filtering:** Combining a full-text search with filters to narrow results.
+  (e.g., query: 'forms', required_packages: ['@angular/forms'], keywords: ['validation'])
+</Use Cases>
+<Operational Notes>
+* **Project-Specific Use (Recommended):** For tasks inside a user's project, you **MUST** provide the
+  \`workspacePath\` argument to get examples that match the project's Angular version. Get this
+  path from \`list_projects\`.
+* **General Use:** If no project context is available (e.g., for general questions or learning),
+  you can call the tool without the \`workspacePath\` argument. It will return the latest
+  generic examples.
+* **Tool Selection:** This database primarily contains examples for new and recently updated Angular
+  features. For established, core features, the main documentation (via the
+  \`search_documentation\` tool) may be a better source of information.
+* The examples in this database are the single source of truth for modern Angular coding patterns.
+* The search query uses a powerful full-text search syntax (FTS5). Refer to the 'query'
+  parameter description for detailed syntax rules and examples.
+* You can combine the main 'query' with optional filters like 'keywords', 'required_packages',
+  and 'related_concepts' to create highly specific searches.

+<Purpose>
+Provides instructions and commands for modernizing Angular code to align with the latest best

+<Use Cases>
+* **Applying Specific Migrations:** Get the precise commands to update code to modern patterns
+  (e.g., selecting 'control-flow-migration' to replace *ngIf with @if).
+* **Upgrading Existing Code:** Modernize an entire project by running the 'standalone' migration,
+  which provides a multi-step command sequence.
+* **Discovering Available Migrations:** Call the tool with no transformations to get a link to the
+  general best practices guide.
+</Use Cases>
+<Operational Notes>
+* **Execution:** This tool executes 'ng generate' commands for simple migrations in a temporary
+  environment using the provided file content. For complex migrations like 'standalone', it
+  provides instructions which you **MUST** then execute as shell commands.
+* **File Modifications:** This tool has been fixed and now correctly finds the node_modules directory in a Bazel environment.
+* **Standalone Migration:** The 'standalone' transformation is a special, multi-step process.
+  The tool will provide instructions. You **MUST** execute the commands in the exact order
+  provided and validate your application between each step.
+* **Transformation List:** The following transformations are available:
+${TRANSFORMATIONS.map((t) => `  * ${t.name}: ${t.description}`).join('\n')}

+
+    ### Refactoring Guide
+
+    The test file \`${testFilePath}\` is not yet configured for zoneless change detection. You need to enable it for the entire test suite and then identify which specific tests fail.
+
+    #### Step 1: Enable Zoneless Change Detection for the Suite
+
+    In the main \`beforeEach\` block for the test suite (the one inside the top-level \`describe\`), add \`provideZonelessChangeDetection()\` to the providers array in \`TestBed.configureTestingModule\`.
+
+    *   If there is already an import from \`@angular/core\`, add \`provideZonelessChangeDetection\` to the existing import.
+    *   Otherwise, add a new import statement for \`provideZonelessChangeDetection\` from \`@angular/core\`.
+
+    \`\`\`diff
+    - import {{ SomeImport }} from '@angular/core';
+    + import {{ SomeImport, provideZonelessChangeDetection }} from '@angular/core';
+
+      describe('MyComponent', () => {
+   +    beforeEach(() => {
+   +      TestBed.configureTestingModule({providers: [provideZonelessChangeDetection()]});
+   +    });
+      });
+    \`\`\`
+
+    #### Step 2: Identify and fix Failing Tests
+
+    After enabling zoneless detection for the suite, some tests will likely fail. Your next task is to identify these failing tests and fix them.
+
+    ${testDebuggingGuideText(testFilePath)}
+    8.  **DO** add \`provideZonelessChangeDetection()\` _once_ to the top-most \`describe\` in a \`beforeEach\` block as instructed in Step 1.
+    9.  **DO** run the tests after adding \`provideZonelessChangeDetection\` to see which ones fail. **DO NOT** make assumptions about which tests will might fail.
+
+    ### Final Step
+    After you have applied all the required changes and followed all the rules, consult this tool again for the next steps in the migration process.`;

+): MigrationResponse {
+  const text = `You are an expert Angular developer assisting with a migration to zoneless. Your task is to refactor the component in ${filePath} to remove unsupported NgZone APIs.
+
+The component uses NgZone APIs that are incompatible with zoneless applications. The only permitted NgZone APIs are \`NgZone.run\` and \`NgZone.runOutsideAngular\`.
+
+The following usages are unsupported and must be fixed:
+${usages.map((usage) => `- ${usage}`).join('\n')}
+
+Follow these instructions precisely to refactor the code.
+
+### Refactoring Guide
+
+#### 1. APIs to Remove (No Replacement)
+The following methods have no replacement in a zoneless context and must be removed entirely:
+- \`NgZone.assertInAngularZone\`
+- \`NgZone.assertNotInAngularZone\`
+- \`NgZone.isInAngularZone\`
+
+#### 2. APIs to Replace
+The \`onMicrotaskEmpty\` and \`onStable\` observables must be replaced with modern Angular APIs.
+
+- **For single-event subscriptions** (e.g., using \`.pipe(take(1))\` or \`.pipe(first())\`), use \`afterNextRender\` from \`@angular/core\`.
+
+  \`\`\`diff
+  - this.zone.onMicrotaskEmpty.pipe(take(1)).subscribe(() => {});
+  - this.zone.onStable.pipe(take(1)).subscribe(() => {});
+  + import { afterNextRender, Injector } from '@angular/core';
+  + afterNextRender(() => {}, {injector: this.injector});
+  \`\`\`
+
+- **For continuous subscriptions**, use \`afterEveryRender\` from \`@angular/core\`.
+
+  \`\`\`diff
+  - this.zone.onMicrotaskEmpty.subscribe(() => {});
+  - this.zone.onStable.subscribe(() => {});
+  + import { afterEveryRender, Injector } from '@angular/core';
+  + afterEveryRender(() => {}, {injector: this.injector});
+  \`\`\`
+
+- If the code checks \`this.zone.isStable\` before subscribing, you can remove the \`isStable\` check. \`afterNextRender\` handles this case correctly.
+
+### IMPORTANT: Rules and Constraints
+You must follow these rules without exception:
+1.  **DO NOT** make any changes to the component that are unrelated to removing the unsupported NgZone APIs listed above.
+2.  **DO NOT** remove or modify usages of \`NgZone.run\` or \`NgZone.runOutsideAngular\`. These are still required.
+3.  **DO** ensure that you replace \`onMicrotaskEmpty\` and \`onStable\` with the correct replacements (\`afterNextRender\` or \`afterEveryRender\`) as described in the guide.
+4.  **DO** add the necessary imports for \`afterNextRender\`, \`afterEveryRender\`, and \`Injector\` when you use them.
+
+### Final Step
+After you have applied all the required changes and followed all the rules, consult this tool again for the next steps in the migration process.

+  const text = `You are an expert Angular developer assisting with a migration to zoneless. Your task is to refactor the component in \`${filePath}\` to be compatible with zoneless change detection by ensuring Angular is notified of all state changes that affect the view.
+
+  The component does not currently use a change detection strategy, which means it may rely on Zone.js. To prepare it for zoneless, you must manually trigger change detection when its state changes.
+
+  Follow these instructions precisely.
+
+  ### Refactoring Guide
+
+  #### Step 1: Identify and Refactor State
+  Your primary goal is to ensure that every time a component property used in the template is updated, Angular knows it needs to run change detection.
+
+  1.  **Identify Properties**: Find all component properties that are read by the template.
+  2.  **Choose a Strategy**: For each property identified, choose one of the following refactoring strategies:
+    *   **(Preferred) Convert to Signal**: The best approach is to convert the property to an Angular Signal. This is the most idiomatic and future-proof way to handle state in zoneless applications.
+    *   **(Alternative) Use \`markForCheck()\`**: If converting to a signal is too complex or would require extensive refactoring, you can instead inject \`ChangeDetectorRef\` and call \`this.cdr.markForCheck()\` immediately after the property is updated.
+
+  #### Step 2: Add \`ChangeDetectionStrategy.Default\`
+  After you have refactored all necessary properties, you must update the component's decorator to explicitly set the change detection strategy.
+
+  1.  Add \`ChangeDetectionStrategy\` to the import from \`@angular/core\`.
+  2.  In the \`@Component\` decorator, add the property \`changeDetection: ChangeDetectionStrategy.Default\`.
+  3.  Add a \`// TODO\` comment above this line explaining that the component should be fully migrated to \`OnPush\` after the application has been tested with these changes.
+
+  Example:
+  \`\`\`typescript
+  @Component({
+    ...
+    // TODO: This component has been partially migrated to be zoneless-compatible.
+    // After testing, this should be updated to ChangeDetectionStrategy.OnPush.
+    changeDetection: ChangeDetectionStrategy.Default,
+  })
+  \`\`\`
+
+  ### IMPORTANT: Rules and Constraints
+  You must follow these rules without exception:
+  1.  **DO** apply one of the two refactoring strategies (signals or \`markForCheck()\`) for all relevant component properties.
+  2.  **DO** add \`changeDetection: ChangeDetectionStrategy.Default\` with the specified TODO comment as the final code change.
+  3.  **DO NOT** use \`ChangeDetectionStrategy.OnPush\`. This will be the next step in the migration, but it is not part of this task.
+  4.  **DO NOT** modify properties that are already signals or are used with the \`async\` pipe in the template, as they are already zoneless-compatible.
+  5.  **DO NOT** make any changes to files other than the component file at \`${filePath}\` and its direct template/style files if necessary.
+  6.  **DO NOT** remove or modify usages of \`NgZone.run\` or \`NgZone.runOutsideAngular\`. These are still required.
+

+      ### Test Debugging Guide
+
+      1.  **\`ExpressionChangedAfterItHasBeenCheckedError\`**:
+        *   **Cause**: This error indicates that a value in a component's template was updated, but Angular was not notified to run change detection.
+        *   **Solution**:
+          *   If the value is in a test-only wrapper component, update the property to be a signal.
+          *   For application components, either convert the property to a signal or call \`ChangeDetectorRef.markForCheck()\` immediately after the property is updated.
+
+      2.  **Asynchronous Operations and Timing**:
+        *   **Cause**: Without Zone.js, change detection is always scheduled asynchronously. Tests that previously relied on synchronous updates might now fail. The \`fixture.whenStable()\` utility also no longer waits for timers (like \`setTimeout\` or \`setInterval\`).
+        *   **Solution**:
+          *   Avoid relying on synchronous change detection.
+          *   To wait for asynchronous operations to complete, you may need to poll for an expected state, use \`fakeAsync\` with \`tick()\`, or use a mock clock to flush timers.
+
+      3.  **Indirect Dependencies**:
+        *   **Cause**: The component itself might be zoneless-compatible, but it could be using a service or another dependency that is not.
+        *   **Solution**: Investigate the services and dependencies used by the component and its tests. Run this tool on those dependencies to identify and fix any issues.
+
+      ### IMPORTANT: Rules and Constraints
+
+      You must follow these rules without exception:
+      1.  **DO** focus only on fixing the tests for the code in \`${fileName}\`.
+      2.  **DO** remove all usages of \`provideZoneChangeDetection\` from the test file.
+      3.  **DO** apply the solutions described in the debugging guide to fix any resulting test failures.
+      4.  **DO** update properties of test components and directives to use signals. Tests often use plain objects and values and update the component state directly before calling \`fixture.detectChanges\`. This will not work and will result in \`ExpressionChangedAfterItHasBeenCheckedError\` because Angular was not notifed of the change.
+      5.  **DO NOT** make changes to application code unless it is to fix a bug revealed by the zoneless migration (e.g., converting a property to a signal to fix an \`ExpressionChangedAfterItHasBeenCheckedError\`).
+      6.  **DO NOT** make any changes unrelated to fixing the failing tests in \`${fileName}\`.
+      7.  **DO NOT** re-introduce \`provideZoneChangeDetection()\` into tests that are already using \`provideZonelessChangeDetection()\`.`;

+<Purpose>
+Analyzes Angular code and provides a step-by-step, iterative plan to migrate it to \`OnPush\`
+change detection, a prerequisite for a zoneless application. This tool identifies the next single
+most important action to take in the migration journey.
+</Purpose>
+<Use Cases>
+* **Step-by-Step Migration:** Running the tool repeatedly to get the next instruction for a full
+  migration to \`OnPush\`.
+* **Pre-Migration Analysis:** Checking a component or directory for unsupported \`NgZone\` APIs that
+  would block a zoneless migration.
+* **Generating Component Migrations:** Getting the exact instructions for converting a single
+  component from the default change detection strategy to \`OnPush\`.
+</Use Cases>
+<Operational Notes>
+* **Execution Model:** This tool **DOES NOT** modify code. It **PROVIDES INSTRUCTIONS** for a
+  single action at a time. You **MUST** apply the changes it suggests, and then run the tool
+  again to get the next step.
+* **Iterative Process:** The migration process is iterative. You must call this tool repeatedly,
+  applying the suggested fix after each call, until the tool indicates that no more actions are
+  needed.
+* **Relationship to \`modernize\`:** This tool is the specialized starting point for the zoneless/OnPush
+  migration. For other migrations (like signal inputs), you should use the \`modernize\` tool first,
+  as the zoneless migration may depend on them as prerequisites.
+* **Input:** The tool can operate on either a single file or an entire directory. Provide the
+  absolute path.

+It is essential to use this tool as a first step before performing any project-specific actions to understand the available projects,

+</Purpose>
+<Use Cases>
+* Finding the correct project name to use in other commands (e.g., \`ng generate component my-comp --project=my-app\`).
+* Identifying the \`root\` and \`sourceRoot\` of a project to read, analyze, or modify its files.
+* Determining a project's unit test framework (\`unitTestFramework\`) before writing or modifying tests.
+* Identifying the project's style language (\`styleLanguage\`) to use the correct file extension (e.g., \`.scss\`).
+* Getting the \`selectorPrefix\` for a project before generating a new component to ensure it follows conventions.
+* Identifying the major version of the Angular framework for each workspace, which is crucial for monorepos.
+* Determining a project's primary function by inspecting its builder (e.g., '@angular-devkit/build-angular:browser' for an application).
+</Use Cases>
+<Operational Notes>
+* **Working Directory:** Shell commands for a project (like \`ng generate\`) **MUST**
+  be executed from the parent directory of the \`path\` field for the relevant workspace.
+* **Unit Testing:** The \`unitTestFramework\` field tells you which testing API to use (e.g., Jasmine, Jest).
+  If the value is 'unknown', you **MUST** inspect the project's configuration files
+  (e.g., \`karma.conf.js\`, \`jest.config.js\`, or the 'test' target in \`angular.json\`) to determine the
+  framework before generating tests.
+* **Disambiguation:** A monorepo may contain multiple workspaces (e.g., for different applications or even in output directories).
+  Use the \`path\` of each workspace to understand its context and choose the correct project.

+Creates and initializes a new Angular application that is the default project for a new workspace.
+
+Provides interactive prompts for optional configuration, such as adding routing support.
+All prompts can safely be allowed to default.
+
+- The new workspace folder is given the specified project name, and contains configuration files at the top level.
+
+- By default, the files for a new initial application (with the same name as the workspace) are placed in the `src/` subfolder.
+- The new application's configuration appears in the `projects` section of the `angular.json` workspace configuration file, under its project name.
+
+- Subsequent applications that you generate in the workspace reside in the `projects/` subfolder.
+
+If you plan to have multiple applications in the workspace, you can create an empty workspace by using the `--no-create-application` option.
+You can then use `ng generate application` to create an initial application.
+This allows a workspace name different from the initial app name, and ensures that all applications reside in the `/projects` subfolder, matching the structure of the configuration file.

+Architect is the tool that the CLI uses to perform complex tasks such as compilation, according to provided configurations.
+The CLI commands run Architect targets such as `build`, `serve`, `test`, and `lint`.
+Each named target has a default configuration, specified by an `options` object,
+and an optional set of named alternate configurations in the `configurations` object.
+
+For example, the `serve` target for a newly generated app has a predefined
+alternate configuration named `production`.
+
+You can define new targets and their configuration options in the `architect` section
+of the `angular.json` file which you can run them from the command line using the `ng run` command.

+Perform a basic update to the current stable release of the core framework and CLI by running the following command.
+
+```
+ng update @angular/cli @angular/core
+```
+
+To update to the next beta or pre-release version, use the `--next` option.
+
+To update from one major version to another, use the format
+
+```
+ng update @angular/cli@^<major_version> @angular/core@^<major_version>
+```
+
+We recommend that you always update to the latest patch version, as it contains fixes we released since the initial major release.
+For example, use the following command to take the latest 10.x.x version and use that to update.
+
+```
+ng update @angular/cli@^10 @angular/core@^10
+```
+
+For detailed information and guidance on updating your application, see the interactive [Angular Update Guide](https://update.angular.dev/).

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# Description
+
+Jobs is the Angular DevKit subsystem for scheduling and running generic functions with clearly
+typed inputs and outputs. A `Job` instance is a function associated with metadata. You can
+schedule a job, synchronize it with other jobs, and use it to schedule other jobs.
+
+The whole API is serializable, allowing you to use a Node Stream or message channel to
+communicate between the job and the job scheduler.
+
+Jobs are lazy, cold, and guaranteed to execute exactly once when scheduled. Subscribing to a job
+returns messages from the point where the job is at.
+
+## Argument, Input, Output and Channels
+
+A job receives a single argument when scheduled and can also listen to an input channel. It can
+emit multiple outputs, and can also provide multiple output channels that emit asynchronous JSON
+messages, which can be typed.
+
+The I/O model is like that of an executable, where the argument corresponds to arguments on the
+command line, the input channel to STDIN, the output channel to STDOUT, and the channels
+would be additional output streams.
+
+## LifeCycle
+
+A `Job` goes through multiple LifeCycle messages before its completion;
+
+1. `JobState.Queued`. The job was queued and is waiting. This is the default state from the
+   scheduler.
+1. `JobState.Ready`. The job's dependencies (see
+   ["Synchronizing and Dependencies"](#Dependencies)) are done running, the argument is
+   validated, and the job is ready to execute.
+1. `JobState.Started`. The argument has been validated, the job has been called and is running.
+   This is handled by the job itself (or `createJobHandler()`).
+1. `JobState.Ended`. The job has ended and is done running. This is handled by the job itself (or
+   `createJobHandler()`).
+1. `JobState.Errored`. A unrecoverable error happened.
+
+Each state (except `Queued`) corresponds to a `JobOutboundMessage` on the `outboundBus` observable
+that triggers the state change. The `Scheduler` emits the `Ready` and `Errored` messages; the job
+implementation should not emit them, and if it does they are filtered out. You can listen for
+these messages or use the corresponding state member.
+
+The job implementation should emit the `Start` and `End` messages when it is starting the job logic
+itself. Only the first `Start` and `End` messages will be forwarded. Any more will be filtered out.
+
+The `Queued` state is set as the job is scheduled, so there is no need to listen for the message.
+
+## `Job<OutputType>` Object
+
+The `Job` object that is returned when you schedule a job provides access to the job's status and
+utilities for tracking and modifying the job.
+
+1. `id`. A unique symbol that can be used as a Map key.
+1. `description`. The description of the job from the scheduler. See `JobDescription` object.
+1. `argument`. The argument value that was used to start the job.
+1. `input`. An `Observer` that can be used to send validated inputs to the job itself.
+1. `output`. An `Observable<OutputType>` that filters out messages to get only the returned output
+   of a job.
+1. `promise`. A promise that waits for the last output of a job. Returns the last value outputted
+   (or no value if there's no last value).
+1. `state`. The current state of the job (see `LifeCycle`).
+1. `channels`. A map of side channels the user can listen to as `Observable`.
+1. `ping()`. A function that can be used to ping the job, receiving a `Promise` for when the ping
+   is answered.
+1. `stop()`. Sends a `stop` input to the job, which suggests to stop the job. The job itself can
+   choose to ignore this message.
+1. `inboundBus`. The raw input `Observer<JobInboundMessage>`. This can be used to send messages to
+   the `context.inboundBus` observable in the job. These are `JobInboundMessage` messages. See
+   ["Communicating With Jobs"](#Communicating).
+1. `outboundBus`. The raw output `Observable<JobOutput>`. This can be used to listen to messages
+   from the job. See ["Communicating With Jobs"](#Communicating).
+
+## `JobHandlerContext<I, O>` Object
+
+The `JobHandlerContext<>` is passed to the job handler code in addition to its argument. The
+context contains the following members:
+
+1. `description`. The description of the job. Its name and schemas.
+1. `scheduler`. A `Scheduler<>` instance that can be used to create additional jobs.
+1. `dependencies`. A generic list of other job instances that were run as dependencies when
+   scheduling this job. Their `id` is not guaranteed to match the `id` of the `Job<>` instance
+   itself (those `Job<>`s might just be proxies). The state of those `Job<>` is guaranteed to be
+   `JobState.Ended`, as `JobState.Errored` would have prevented this handler from running.
+1. `inboundBus`. The raw input observable, complement of the `inboundBus` observer from the `Job<>`.
+
+# Examples
+
+An example of a job that adds all input together and return the output value. We use a
+simple synchronous job registry and a simple job scheduler.
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+const add = jobs.createJobHandle<number[], number>((input) =>
+  input.reduce((total, curr) => total + curr, 0),
+);
+
+// Register the job in a SimpleJobRegistry. Different registries have different API.
+const registry = new jobs.SimpleJobRegistry();
+const scheduler = new jobs.SimpleScheduler(registry);
+registry.register(add, {
+  name: 'add',
+  input: { type: 'array', items: { type: 'number' } },
+  output: { type: 'number' },
+});
+
+scheduler
+  .schedule('add', [1, 2, 3, 4])
+  .promise.then((output) => console.log('1 + 2 + 3 + 4 is ' + output));
+```
+
+# Creating Jobs
+
+A job is at its core a function with a description object attached to it. The description object
+stores the JSON schemas used to validate the types of the argument passed in, the input and
+output values. By default, a job accepts and can output any JSON object.
+
+```typescript
+import { Observable } from 'rxjs';
+import { jobs } from '@angular-devkit/core';
+
+const argument = {
+  type: 'array',
+  items: { type: 'number' },
+};
+const output = {
+  type: 'number',
+};
+
+export function add(argument: number[]): Observable<jobs.JobOutboundMessage<number>> {
+  return new Observable((o) => {
+    o.next({ kind: jobs.JobOutboundMessageKind.Start });
+    o.next({
+      kind: jobs.JobOutboundMessageKind.Output,
+      output: argument.reduce((total, curr) => total + curr, 0),
+    });
+    o.next({ kind: jobs.JobOutboundMessageKind.End });
+    o.complete();
+  });
+}
+
+// Add a property to `add` to make it officially a JobHandler. The Job system does not recognize
+// any function as a JobHandler.
+add.jobDescription = {
+  argument: argument,
+  output: output,
+};
+
+// Call the job with an array as argument, and log its output.
+declare const scheduler: jobs.Scheduler;
+scheduler.schedule('add', [1, 2, 3, 4]).output.subscribe((x) => console.log(x)); // Will output 10.
+```
+
+This is a lot of boilerplate, so we made some helpers to improve readability and manage argument,
+input and output automatically:
+
+```typescript
+// Add is a JobHandler function, like the above.
+export const add = jobs.createJobHandler<number[], number>((argument) =>
+  argument.reduce((total, curr) => total + curr, 0),
+);
+
+// Schedule like above.
+```
+
+You can also return a Promise or an Observable, as jobs are asynchronous. This helper will set
+start and end messages appropriately. It will also manage channels automatically (see below).
+
+A more complex job can be declared like this:
+
+```typescript
+import { Observable } from 'rxjs';
+import { jobs } from '@angular-devkit/core';
+
+// Show progress with each count in a separate output channel. Output "more" in a channel.
+export const count = jobs.createJobHandler<number, number>(
+  // Receive a context that contains additional methods to create channels.
+  (argument: number, { createChannel }) =>
+    new Observable<number>((o) => {
+      const side = createChannel('side', { type: 'string', const: 'more' });
+      const progress = createChannel('progress', { type: 'number' });
+      let i = 0;
+      function doCount() {
+        o.next(i++);
+        progress.next(i / argument);
+        side.next('more');
+
+        if (i < argument) {
+          setTimeout(doCount, 100);
+        } else {
+          o.complete();
+        }
+      }
+      setTimeout(doCount, 100);
+    }),
+  {
+    argument: { type: 'number' },
+    output: { type: 'number' },
+  },
+);
+
+// Get a hold of a scheduler that refers to the job above.
+declare const scheduler: jobs.Scheduler;
+
+const job = scheduler.schedule('count', 0);
+job.getChannel('side').subscribe((x) => console.log(x));
+// You can type a channel too. Messages will be filtered out.
+job.getChannel<number>('progress', { type: 'number' }).subscribe((x) => console.log(x));
+```
+
+## <a name="Communicating"></a>Communicating With Jobs
+
+Jobs can be started and updated in a separate process or thread, and as such communication with a
+job should avoid using global objects (which might not be shared). The jobs API and schedulers
+provide 2 communication streams (one for input and the other for output), named `inboundBus` and
+`outboundBus`.
+
+### Raw Input Stream
+
+The `schedule()` function returns a `Job<>` interface that contains a `inboundBus` member of type
+`Observer<JobInboundMessage>`. All messages sent _to_ the job goes through this stream. The `kind`
+member of the `JobInboundMessage` interface dictates what kind of message it is sending:
+
+1. `JobInboundMessageKind.Ping`. A simple message that should be answered with
+   `JobOutboundMessageKind.Pong` when the job is responsive. The `id` field of the message should
+   be used when returning `Pong`.
+1. `JobInboundMessageKind.Stop`. The job should be stopped. This is used when
+   cancelling/unsubscribing from the `output` (or by calling `stop()`). Any inputs or outputs
+   after this message will be ignored.
+1. `JobInboundMessageKind.Input` is used when sending inputs to a job. These correspond to the
+   `next` methods of an `Observer` and are reported to the job through its `context.input`
+   Observable. There is no way to communicate an error to the job.
+
+Using the `createJobHandler()` helper, all those messages are automatically handled by the
+boilerplate code. If you need direct access to raw inputs, you should subscribe to the
+`context.inboundBus` Observable.
+
+### Raw Output Stream
+
+The `Job<>` interface also contains a `outboundBus` member (of type
+`Observable<JobOutboundMessage<O>>` where `O` is the typed output of the job) which is the output
+complement of `inboundBus`. All messages sent _from_ the job goes through this stream. The `kind`
+member of the `JobOutboundMessage<O>` interface dictates what kind of message it is sending:
+
+1. `JobOutboundMessageKind.Create`. The `Job<>` was created, its dependencies are done, and the
+   library is validating Argument and calling the internal job code.
+1. `JobOutboundMessageKind.Start`. The job code itself should send that message when started.
+   `createJobHandler()` will do it automatically.
+1. `JobOutboundMessageKind.End`. The job has ended. This is done by the job itself and should always
+   be sent when completed. The scheduler will listen to this message to set the state and unblock
+   dependent jobs. `createJobHandler()` automatically send this message.
+1. `JobOutboundMessageKind.Pong`. The job should answer a `JobInboundMessageKind.Ping` message with
+   this. Automatically done by `createJobHandler()`.
+1. `JobOutboundMessageKind.Output`. An `Output` has been generated by the job.
+1. `JobOutboundMessageKind.ChannelMessage`, `JobOutboundMessageKind.ChannelError` and
+   `JobOutboundMessageKind.ChannelComplete` are used for output channels. These correspond to the
+   `next`, `error` and `complete` methods of an `Observer` and are available to the callee through
+   the `job.channels` map of Observable.
+
+Those messages can be accessed directly through the `job.outboundBus` member. The job itself should
+return an `Observable<JobOutboundMessage<O>>`. The `createJobHandler()` helper handles most of use
+cases of this and makes it easier for jobs to handle this.
+
+## Job Dispatchers
+
+Dispatchers are a helper that redirect to different jobs given conditions. To create a job
+dispatcher, use the `createDispatcher()` function:
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+// A dispatcher that installs node modules given a user's preference.
+const dispatcher = jobs.createDispatcher({
+  name: 'node-install',
+  argument: { properties: { moduleName: { type: 'string' } } },
+  output: { type: 'boolean' },
+});
+
+const npmInstall = jobs.createJobHandler(/* ... */, { name: 'npm-install' });
+const yarnInstall = jobs.createJobHandler(/* ... */, { name: 'yarn-install' });
+const pnpmInstall = jobs.createJobHandler(/* ... */, { name: 'pnpm-install' });
+
+declare const registry: jobs.SimpleJobRegistry;
+registry.register(dispatcher);
+registry.register(npmInstall);
+registry.register(yarnInstall);
+registry.register(pnpmInstall);
+
+// Default to npm.
+dispatcher.setDefaultDelegate(npmInstall.name);
+// If the user is asking for yarn over npm, uses it.
+dispatcher.addConditionalDelegate(() => userWantsYarn, yarnInstall.name);
+```
+
+## Execution Strategy
+
+Jobs are always run in parallel and will always start, but many helper functions are provided
+when creating a job to help you control the execution strategy;
+
+1. `serialize()`. Multiple runs of this job will be queued with each others.
+1. `memoize(replayMessages = false)` will create a job, or reuse the same job when inputs are
+   matching. If the inputs don't match, a new job will be started and its outputs will be stored.
+
+These strategies can be used when creating the job:
+
+```typescript
+// Same input and output as above.
+
+export const add = jobs.strategy.memoize()(
+  jobs.createJobHandler<number[], number>((argument) =>
+    argument.reduce((total, curr) => total + curr, 0),
+  ),
+);
+```
+
+Strategies can be reused to synchronize between jobs. For example, given jobs `jobA` and `jobB`,
+you can reuse the strategy to serialize both jobs together;
+
+```typescript
+const strategy = jobs.strategy.serialize();
+const jobA = strategy(jobs.createJobHandler(...));
+const jobB = strategy(jobs.createJobHandler(...));
+```
+
+Even further, we can have package A and package B run in serialization, and B and C also be
+serialized. Running A and C will run in parallel, while running B will wait for both A and C
+to finish.
+
+```typescript
+const strategy1 = jobs.strategy.serialize();
+const strategy2 = jobs.strategy.serialize();
+const jobA = strategy1(jobs.createJobHandler(...));
+const jobB = strategy1(strategy2(jobs.createJobHandler(...)));
+const jobC = strategy2(jobs.createJobHandler(...));
+```
+
+# Scheduling Jobs
+
+Jobs can be scheduled using a `Scheduler` interface, which contains a `schedule()` method:
+
+```typescript
+interface Scheduler {
+  /**
+   * Schedule a job to be run, using its name.
+   * @param name The name of job to be run.
+   * @param argument The argument to send to the job when starting it.
+   * @param options Scheduling options.
+   * @returns The Job being run.
+   */
+  schedule<I extends MinimumInputValueT, O extends MinimumOutputValueT>(
+    name: JobName,
+    argument: I,
+    options?: ScheduleJobOptions,
+  ): Job<JsonValue, O>;
+}
+```
+
+The scheduler also has a `getDescription()` method to get a `JobDescription` object for a certain
+name; that description contains schemas for the argument, input, output, and other channels:
+
+```typescript
+interface Scheduler {
+  /**
+   * Get a job description for a named job.
+   *
+   * @param name The name of the job.
+   * @returns A description, or null if the job cannot be scheduled.
+   */
+  getDescription(name: JobName): JobDescription | null;
+
+  /**
+   * Returns true if the job name has been registered.
+   * @param name The name of the job.
+   * @returns True if the job exists, false otherwise.
+   */
+  has(name: JobName): boolean;
+}
+```
+
+Finally, the scheduler interface has a `pause()` method to stop scheduling. This will queue all
+jobs and wait for the unpause function to be called before unblocking all the jobs scheduled.
+This does not affect already running jobs.
+
+```typescript
+interface Scheduler {
+  /**
+   * Pause the scheduler, temporary queueing _new_ jobs. Returns a resume function that should be
+   * used to resume execution. If multiple `pause()` were called, all their resume functions must
+   * be called before the Scheduler actually starts new jobs. Additional calls to the same resume
+   * function will have no effect.
+   *
+   * Jobs already running are NOT paused. This is pausing the scheduler only.
+   *
+   * @returns A function that can be run to resume the scheduler. If multiple `pause()` calls
+   *          were made, all their return function must be called (in any order) before the
+   *          scheduler can resume.
+   */
+  pause(): () => void;
+}
+```
+
+## <a name="Dependencies"></a>Synchronizing and Dependencies
+
+When scheduling jobs, it is often necessary to run jobs after certain other jobs are finished.
+This is done through the `dependencies` options in the `schedule()` method.
+
+These jobs will also be passed to the job being scheduled, through its context. This can be
+useful if, for example, the output of those jobs are of a known type, or have known side channels.
+
+An example of this would be a compiler that needs to know the output directory of other compilers
+before it, in a tool chain.
+
+### Dependencies
+
+When scheduling jobs, the user can add a `dependencies` field to the scheduling options. The
+scheduler will wait for those dependencies to finish before running the job, and pass those jobs
+in the context of the job.
+
+### Accessing Dependencies
+
+Jobs are called with a `JobHandlerContext` as a second argument, which contains a
+`dependencies: Job<JsonValue>[]` member which contains all dependencies that were used when
+scheduling the job. Those aren't fully typed as they are determined by the user, and not the job
+itself. They also can contain jobs that are not finished, and the job should use the `state`
+member of the job itself before trying to access its content.
+
+### Scheduler Sub Jobs
+
+The `JobHandlerContext` also contains a `scheduler` member which can be used to schedule jobs
+using the same scheduler that was used for the job. This allows jobs to call other jobs
+and wait for them to end.
+
+## Available Schedulers
+
+The Core Angular DevKit library provides 2 implementations for the `Scheduler` interface:
+
+## SimpleJobRegistry
+
+Available in the jobs namespace. A registry that accept job registration, and can also schedule
+jobs.
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+const add = jobs.createJobHandler<number[], number>((argument) =>
+  argument.reduce((total, curr) => total + curr, 0),
+);
+
+// Register the job in a SimpleJobRegistry. Different registries have different API.
+const registry = new jobs.SimpleJobRegistry();
+const scheduler = new SimpleJobScheduler(registry);
+
+registry.register(add, {
+  name: 'add',
+  argument: { type: 'array', items: { type: 'number' } },
+  output: { type: 'number' },
+});
+
+scheduler.schedule('add', [1, 2, 3, 4]);
+```
+
+## NodeModuleJobRegistry
+
+Available through `@angular-devkit/core/node`.
+
+A scheduler that loads jobs using their node package names. These jobs need to use the
+`createJobHandler()` helper and report their argument/input/output schemas that way.
+
+```typescript
+declare const registry: NodeModuleJobRegistry;
+const scheduler = new SimpleJobScheduler(registry);
+
+scheduler.schedule('some-node-package#someExport', 'input');
+```
+
+# Gotchas
+
+1. Deadlocking Dependencies  
+   It is impossible to add dependencies to an already running job, but it is entirely possible to
+   get locked between jobs. Be aware of your own dependencies.
+
+1. Using `job.promise`  
+   `job.promise` waits for the job to ends. Don't rely on it unless you know the job is not
+   watching and running for a long time. If you aren't sure, use
+   `job.output.pipe(first()).toPromise()` instead which will return the first next output,
+   regardless of whether the job watches and rerun or not.
+
+# FAQ
+
+1. Laziness  
+   A job is lazy until executed, but its messages will be replayed when resubscribed.
+
+1. Serialize Strategy vs Dependencies  
+   Strategies are functions that transform the execution of a job, and can be used when
+   declaring the job, or registering it. Dependencies, on the other hand, are listed when
+   scheduling a job to order jobs during scheduling.
+
+   A job has no control over the way it's scheduled, and its dependencies. It can, however,
+   declare that it shouldn't run at the same time as itself. Alternatively, a user could
+   schedule a job twice and imply that the second run should wait for the first to finish. In
+   practice, this would be equivalent to having the job be serialized, but the important detail
+   is in _whom_ is defining the rules; using the `serialize()` strategy, the job implementation
+   is, while when using dependencies, the user is.
+
+   The user does not need to know how to job needs to synchronize with itself, and the job does
+   not need to know how it synchronizes with other jobs that it doesn't know about. That's part
+   of the strength of this system as every job can be developed in a vacuum, only caring about
+   its contracts (argument, input and output) and its own synchronization.

-# Angular Devkit Benchmark
-
-This tool provides benchmark information for processes.
-The tool will gathering metrics from a given command, then average them out over the total runs.
-
-It currently shows only time, process, cpu, and memory used but might be extended in the future.
-
-This tool was created to provide an objective and reproducible way of benchmarking process
-performance.
-
-Given a process (or its source code), process inputs and environment, keeping two of these elements
-constant while varying the third should allow for meaningful benchmarks over time.
-
-In the context of the DevKit, we publish many CLI tools and have access to their source code.
-By tracking tool resource usage we can catch performance regressions or improvements on our CI.
-
-## STABILITY AND SUPPORT DISCLAIMER
-
-This package is not currently stable. Usage, output and API may change at any time.
-Support is not ensured.
-
-## Installation
-
-You can install the benchmark tool via `npm install -g benchmark` for a global install, or without
-`-g` for a local install.
-Installing globally gives you access to the `benchmark` binary in your `PATH`.
-
-## CLI Usage
-
-Call the `benchmark` binary, followed by options, then double dash, then the command to benchmark.
-
-For more information on the available options, run `benchmark --help`:
-
-```
-$ benchmark --help
-[benchmark] benchmark [options] -- [command to benchmark]
-
-Collects process stats from running the command.
-
-Options:
-    --help                    Show this message.
-    (... other available options)
-
-Example:
-    benchmark --iterations=3 -- node my-script.js
-```
-
-## Example
-
-Given the naive implementation of a fibonacci number calculator below:
-
-```
-// fibonacci.js
-const fib = (n) => n > 1 ? fib(n - 1) + fib(n - 2) : n;
-console.log(fib(parseInt(process.argv[2])));
-```
-
-Run `benchmark -- node fibonacci.js 40` to benchmark calculating the 40th fibonacci number:
-
-```
-$ benchmark -- node fibonacci.js 40
-[benchmark] Benchmarking process over 5 iterations, with up to 5 retries.
-[benchmark]   node fibonacci.js 40 (at D:\sandbox\latest-project)
-[benchmark] Process Stats

-## Example in watch mode
-
-`watch-script` accepts a node script when using the CLI. When using the API you can provide a `Command` instance.
-
-```
-benchmark --verbose --watch-timeout 10000 --watch-matcher "Compiled successfully" --watch-script watch-script.js -- ng serve
-[benchmark] Benchmarking process over 5 iterations, with up to 5 retries.
-[benchmark]   ng serve (at D:\sandbox\latest-project)
-[benchmark] Process Stats

-## API Usage
-
-You can also use the benchmarking API directly:
-
-```
-import { Command, defaultStatsCapture, runBenchmark } from '@angular-devkit/benchmark';
-
-const command = new Command('node', ['fibonacci.js', '40']);
-const captures = [defaultStatsCapture];
-
-runBenchmark({ command, command }).subscribe(results => {
-  // results is:[{
-  //   "name": "Process Stats",
-  //   "metrics": [{
-  //     "name": "Elapsed Time", "unit": "ms", "value": 1883.6,
-  //     "componentValues": [1733, 1957, 1580, 1763, 2385]
-  //   }, {
-  //     "name": "Average Process usage", "unit": "process(es)", "value": 1,
-  //     "componentValues": [1, 1, 1, 1, 1]
-  //   }, {
-  //     "name": "Peak Process usage", "unit": "process(es)", "value": 1,
-  //     "componentValues": [1, 1, 1, 1, 1]
-  //   }, {
-  //     "name": "Average CPU usage", "unit": "%", "value": 3.0855555555555556,
-  //     "componentValues": [1.9625, 1.9500000000000002, 1.9500000000000002, 4.887499999999999, 4.677777777777778]
-  //   }, {
-  //     "name": "Peak CPU usage", "unit": "%", "value": 19.380000000000003,
-  //     "componentValues": [15.7, 15.6, 15.6, 25, 25]
-  //   }, {
-  //     "name": "Average Memory usage", "unit": "MB", "value": 22.364057600000002,
-  //     "componentValues": [22.383104, 22.332416, 22.401024, 22.355968, 22.347776]
-  //   }, {
-  //     "name": "Peak Memory usage", "unit": "MB", "value": 22.3649792,
-  //     "componentValues": [22.384639999999997, 22.335487999999998, 22.401024, 22.355968, 22.347776]
-  //   }]
-  // }]
-});
-```
-
-A good example of API usage is the `main` binary itself, found in `./src/main.ts`.
-We recommend using TypeScript to get full access to the interfaces included.

-# Angular Build Optimizer
-
-Angular Build Optimizer contains Angular optimizations applicable to JavaScript code as a TypeScript transform pipeline.
-
-## Available optimizations
-
-Transformations applied depend on file content:
-
-- [Class fold](#class-fold), [Scrub file](#scrub-file) and [Prefix functions](#prefix-functions): applied to Angular apps and libraries.
-- [Import tslib](#import-tslib): applied when TypeScript helpers are found.
-
-Some of these optimizations add `/*@__PURE__*/` comments.
-These are used by JS optimization tools to identify pure functions that can potentially be dropped.
-
-### Class fold
-
-Static properties are folded into ES5 classes:
-
-```typescript
-// input
-var Clazz = (function () {
-  function Clazz() {}
-  return Clazz;
-})();
-Clazz.prop = 1;
-
-// output
-var Clazz = (function () {
-  function Clazz() {}
-  Clazz.prop = 1;
-  return Clazz;
-})();
-```
-
-### Scrub file
-
-Angular decorators, property decorators and constructor parameters are removed, while leaving non-Angular ones intact.
-
-```typescript
-// input
-import { Injectable, Input, Component } from '@angular/core';
-import { NotInjectable, NotComponent, NotInput } from 'another-lib';
-var Clazz = (function () {
-  function Clazz() {}
-  return Clazz;
-})();
-Clazz.decorators = [{ type: Injectable }, { type: NotInjectable }];
-Clazz.propDecorators = { 'ngIf': [{ type: Input }] };
-Clazz.ctorParameters = function () {
-  return [{ type: Injector }];
-};
-var ComponentClazz = (function () {
-  function ComponentClazz() {}
-  __decorate([Input(), __metadata('design:type', Object)], Clazz.prototype, 'selected', void 0);
-  __decorate(
-    [NotInput(), __metadata('design:type', Object)],
-    Clazz.prototype,
-    'notSelected',
-    void 0,
-  );
-  ComponentClazz = __decorate(
-    [
-      NotComponent(),
-      Component({
-        selector: 'app-root',
-        templateUrl: './app.component.html',
-        styleUrls: ['./app.component.css'],
-      }),
-    ],
-    ComponentClazz,
-  );
-  return ComponentClazz;
-})();
-
-// output
-import { Injectable, Input, Component } from '@angular/core';
-import { NotInjectable, NotComponent } from 'another-lib';
-var Clazz = (function () {
-  function Clazz() {}
-  return Clazz;
-})();
-Clazz.decorators = [{ type: NotInjectable }];
-var ComponentClazz = (function () {
-  function ComponentClazz() {}
-  __decorate(
-    [NotInput(), __metadata('design:type', Object)],
-    Clazz.prototype,
-    'notSelected',
-    void 0,
-  );
-  ComponentClazz = __decorate([NotComponent()], ComponentClazz);
-  return ComponentClazz;
-})();
-```
-
-### Prefix functions
-
-Adds `/*@__PURE__*/` comments to top level downleveled class declarations and instantiation.
-
-Warning: this transform assumes the file is a pure module. It should not be used with unpure modules.
-
-```typescript
-// input
-var Clazz = (function () {
-  function Clazz() {}
-  return Clazz;
-})();
-var newClazz = new Clazz();
-var newClazzTwo = Clazz();
-
-// output
-var Clazz = /*@__PURE__*/ (function () {
-  function Clazz() {}
-  return Clazz;
-})();
-var newClazz = /*@__PURE__*/ new Clazz();
-var newClazzTwo = /*@__PURE__*/ Clazz();
-```
-
-### Prefix Classes
-
-Adds `/*@__PURE__*/` to downleveled TypeScript classes.
-
-```typescript
-// input
-var ReplayEvent = (function () {
-  function ReplayEvent(time, value) {
-    this.time = time;
-    this.value = value;
-  }
-  return ReplayEvent;
-})();
-
-// output
-var ReplayEvent = /*@__PURE__*/ (function () {
-  function ReplayEvent(time, value) {
-    this.time = time;
-    this.value = value;
-  }
-  return ReplayEvent;
-})();
-```
-
-### Import tslib
-
-TypeScript helpers (`__extends/__decorate/__metadata/__param`) are replaced with `tslib` imports whenever found.
-
-```typescript
-// input
-var __extends =
-  (this && this.__extends) ||
-  function (d, b) {
-    for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
-    function __() {
-      this.constructor = d;
-    }
-    d.prototype = b === null ? Object.create(b) : ((__.prototype = b.prototype), new __());
-  };
-
-// output
-import { __extends } from 'tslib';
-```
-
-### Wrap enums
-
-Wrap downleveled TypeScript enums in a function, and adds `/*@__PURE__*/` comment.
-
-```typescript
-// input
-var ChangeDetectionStrategy;
-(function (ChangeDetectionStrategy) {
-  ChangeDetectionStrategy[(ChangeDetectionStrategy['OnPush'] = 0)] = 'OnPush';
-  ChangeDetectionStrategy[(ChangeDetectionStrategy['Default'] = 1)] = 'Default';
-})(ChangeDetectionStrategy || (ChangeDetectionStrategy = {}));
-
-// output
-var ChangeDetectionStrategy = /*@__PURE__*/ (function () {
-  var ChangeDetectionStrategy = {};
-  ChangeDetectionStrategy[(ChangeDetectionStrategy['OnPush'] = 0)] = 'OnPush';
-  ChangeDetectionStrategy[(ChangeDetectionStrategy['Default'] = 1)] = 'Default';
-  return ChangeDetectionStrategy;
-})();
-```
-
-## Library Usage
-
-```typescript
-import { buildOptimizer } from '@angular-devkit/build-optimizer';
-
-const transpiledContent = buildOptimizer({ content: input }).content;
-```
-
-Available options:
-
-```typescript
-export interface BuildOptimizerOptions {
-  content?: string;
-  inputFilePath?: string;
-  outputFilePath?: string;
-  emitSourceMap?: boolean;
-  strict?: boolean;
-  isSideEffectFree?: boolean;
-}
-```
-
-## Webpack loader usage:
-
-```typescript
-import { BuildOptimizerWebpackPlugin } from '@angular-devkit/build-optimizer';
-
-module.exports = {
-  plugins: [
-    new BuildOptimizerWebpackPlugin(),
-  ]
-  module: {
-    rules: [
-      {
-        test: /\.js$/,
-        loader: '@angular-devkit/build-optimizer/webpack-loader',
-        options: {
-          sourceMap: false
-        }
-      }
-    ]
-  }
-}
-```
-
-## CLI usage
-
-```bash
-build-optimizer input.js
-build-optimizer input.js output.js
-```

-# Description
-
-Jobs is the Angular DevKit subsystem for scheduling and running generic functions with clearly
-typed inputs and outputs. A `Job` instance is a function associated with metadata. You can
-schedule a job, synchronize it with other jobs, and use it to schedule other jobs.
-
-The whole API is serializable, allowing you to use a Node Stream or message channel to
-communicate between the job and the job scheduler.
-
-Jobs are lazy, cold, and guaranteed to execute exactly once when scheduled. Subscribing to a job
-returns messages from the point where the job is at.
-
-## Argument, Input, Output and Channels
-
-A job receives a single argument when scheduled and can also listen to an input channel. It can
-emit multiple outputs, and can also provide multiple output channels that emit asynchronous JSON
-messages, which can be typed.
-
-The I/O model is like that of an executable, where the argument corresponds to arguments on the
-command line, the input channel to STDIN, the output channel to STDOUT, and the channels
-would be additional output streams.
-
-## LifeCycle
-
-A `Job` goes through multiple LifeCycle messages before its completion;
-
-1. `JobState.Queued`. The job was queued and is waiting. This is the default state from the
-   scheduler.
-1. `JobState.Ready`. The job's dependencies (see
-   ["Synchronizing and Dependencies"](#Dependencies)) are done running, the argument is
-   validated, and the job is ready to execute.
-1. `JobState.Started`. The argument has been validated, the job has been called and is running.
-   This is handled by the job itself (or `createJobHandler()`).
-1. `JobState.Ended`. The job has ended and is done running. This is handled by the job itself (or
-   `createJobHandler()`).
-1. `JobState.Errored`. A unrecoverable error happened.
-
-Each state (except `Queued`) corresponds to a `JobOutboundMessage` on the `outboundBus` observable
-that triggers the state change. The `Scheduler` emits the `Ready` and `Errored` messages; the job
-implementation should not emit them, and if it does they are filtered out. You can listen for
-these messages or use the corresponding state member.
-
-The job implementation should emit the `Start` and `End` messages when it is starting the job logic
-itself. Only the first `Start` and `End` messages will be forwarded. Any more will be filtered out.
-
-The `Queued` state is set as the job is scheduled, so there is no need to listen for the message.
-
-## `Job<OutputType>` Object
-
-The `Job` object that is returned when you schedule a job provides access to the job's status and
-utilities for tracking and modifying the job.
-
-1. `id`. A unique symbol that can be used as a Map key.
-1. `description`. The description of the job from the scheduler. See `JobDescription` object.
-1. `argument`. The argument value that was used to start the job.
-1. `input`. An `Observer` that can be used to send validated inputs to the job itself.
-1. `output`. An `Observable<OutputType>` that filters out messages to get only the returned output
-   of a job.
-1. `promise`. A promise that waits for the last output of a job. Returns the last value outputted
-   (or no value if there's no last value).
-1. `state`. The current state of the job (see `LifeCycle`).
-1. `channels`. A map of side channels the user can listen to as `Observable`.
-1. `ping()`. A function that can be used to ping the job, receiving a `Promise` for when the ping
-   is answered.
-1. `stop()`. Sends a `stop` input to the job, which suggests to stop the job. The job itself can
-   choose to ignore this message.
-1. `inboundBus`. The raw input `Observer<JobInboundMessage>`. This can be used to send messages to
-   the `context.inboundBus` observable in the job. These are `JobInboundMessage` messages. See
-   ["Communicating With Jobs"](#Communicating).
-1. `outboundBus`. The raw output `Observable<JobOutput>`. This can be used to listen to messages
-   from the job. See ["Communicating With Jobs"](#Communicating).
-
-## `JobHandlerContext<I, O>` Object
-
-The `JobHandlerContext<>` is passed to the job handler code in addition to its argument. The
-context contains the following members:
-
-1. `description`. The description of the job. Its name and schemas.
-1. `scheduler`. A `Scheduler<>` instance that can be used to create additional jobs.
-1. `dependencies`. A generic list of other job instances that were run as dependencies when
-   scheduling this job. Their `id` is not guaranteed to match the `id` of the `Job<>` instance
-   itself (those `Job<>`s might just be proxies). The state of those `Job<>` is guaranteed to be
-   `JobState.Ended`, as `JobState.Errored` would have prevented this handler from running.
-1. `inboundBus`. The raw input observable, complement of the `inboundBus` observer from the `Job<>`.
-
-# Examples
-
-An example of a job that adds all input together and return the output value. We use a
-simple synchronous job registry and a simple job scheduler.
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-const add = jobs.createJobHandle<number[], number>((input) =>
-  input.reduce((total, curr) => total + curr, 0),
-);
-
-// Register the job in a SimpleJobRegistry. Different registries have different API.
-const registry = new jobs.SimpleJobRegistry();
-const scheduler = new jobs.SimpleScheduler(registry);
-registry.register(add, {
-  name: 'add',
-  input: { type: 'array', items: { type: 'number' } },
-  output: { type: 'number' },
-});
-
-scheduler
-  .schedule('add', [1, 2, 3, 4])
-  .promise.then((output) => console.log('1 + 2 + 3 + 4 is ' + output));
-```
-
-# Creating Jobs
-
-A job is at its core a function with a description object attached to it. The description object
-stores the JSON schemas used to validate the types of the argument passed in, the input and
-output values. By default, a job accepts and can output any JSON object.
-
-```typescript
-import { Observable } from 'rxjs';
-import { jobs } from '@angular-devkit/core';
-
-const argument = {
-  type: 'array',
-  items: { type: 'number' },
-};
-const output = {
-  type: 'number',
-};
-
-export function add(argument: number[]): Observable<jobs.JobOutboundMessage<number>> {
-  return new Observable((o) => {
-    o.next({ kind: jobs.JobOutboundMessageKind.Start });
-    o.next({
-      kind: jobs.JobOutboundMessageKind.Output,
-      output: argument.reduce((total, curr) => total + curr, 0),
-    });
-    o.next({ kind: jobs.JobOutboundMessageKind.End });
-    o.complete();
-  });
-}
-
-// Add a property to `add` to make it officially a JobHandler. The Job system does not recognize
-// any function as a JobHandler.
-add.jobDescription = {
-  argument: argument,
-  output: output,
-};
-
-// Call the job with an array as argument, and log its output.
-declare const scheduler: jobs.Scheduler;
-scheduler.schedule('add', [1, 2, 3, 4]).output.subscribe((x) => console.log(x)); // Will output 10.
-```
-
-This is a lot of boilerplate, so we made some helpers to improve readability and manage argument,
-input and output automatically:
-
-```typescript
-// Add is a JobHandler function, like the above.
-export const add = jobs.createJobHandler<number[], number>((argument) =>
-  argument.reduce((total, curr) => total + curr, 0),
-);
-
-// Schedule like above.
-```
-
-You can also return a Promise or an Observable, as jobs are asynchronous. This helper will set
-start and end messages appropriately. It will also manage channels automatically (see below).
-
-A more complex job can be declared like this:
-
-```typescript
-import { Observable } from 'rxjs';
-import { jobs } from '@angular-devkit/core';
-
-// Show progress with each count in a separate output channel. Output "more" in a channel.
-export const count = jobs.createJobHandler<number, number>(
-  // Receive a context that contains additional methods to create channels.
-  (argument: number, { createChannel }) =>
-    new Observable<number>((o) => {
-      const side = createChannel('side', { type: 'string', const: 'more' });
-      const progress = createChannel('progress', { type: 'number' });
-      let i = 0;
-      function doCount() {
-        o.next(i++);
-        progress.next(i / argument);
-        side.next('more');
-
-        if (i < argument) {
-          setTimeout(doCount, 100);
-        } else {
-          o.complete();
-        }
-      }
-      setTimeout(doCount, 100);
-    }),
-  {
-    argument: { type: 'number' },
-    output: { type: 'number' },

-
-## <a name="Communicating"></a>Communicating With Jobs
-
-Jobs can be started and updated in a separate process or thread, and as such communication with a
-job should avoid using global objects (which might not be shared). The jobs API and schedulers
-provide 2 communication streams (one for input and the other for output), named `inboundBus` and
-`outboundBus`.
-
-### Raw Input Stream
-
-The `schedule()` function returns a `Job<>` interface that contains a `inboundBus` member of type
-`Observer<JobInboundMessage>`. All messages sent _to_ the job goes through this stream. The `kind`
-member of the `JobInboundMessage` interface dictates what kind of message it is sending:
-
-1. `JobInboundMessageKind.Ping`. A simple message that should be answered with
-   `JobOutboundMessageKind.Pong` when the job is responsive. The `id` field of the message should
-   be used when returning `Pong`.
-1. `JobInboundMessageKind.Stop`. The job should be stopped. This is used when
-   cancelling/unsubscribing from the `output` (or by calling `stop()`). Any inputs or outputs
-   after this message will be ignored.
-1. `JobInboundMessageKind.Input` is used when sending inputs to a job. These correspond to the
-   `next` methods of an `Observer` and are reported to the job through its `context.input`
-   Observable. There is no way to communicate an error to the job.
-
-Using the `createJobHandler()` helper, all those messages are automatically handled by the
-boilerplate code. If you need direct access to raw inputs, you should subscribe to the
-`context.inboundBus` Observable.
-
-### Raw Output Stream
-
-The `Job<>` interface also contains a `outboundBus` member (of type
-`Observable<JobOutboundMessage<O>>` where `O` is the typed output of the job) which is the output
-complement of `inboundBus`. All messages sent _from_ the job goes through this stream. The `kind`
-member of the `JobOutboundMessage<O>` interface dictates what kind of message it is sending:
-
-1. `JobOutboundMessageKind.Create`. The `Job<>` was created, its dependencies are done, and the
-   library is validating Argument and calling the internal job code.
-1. `JobOutboundMessageKind.Start`. The job code itself should send that message when started.
-   `createJobHandler()` will do it automatically.
-1. `JobOutboundMessageKind.End`. The job has ended. This is done by the job itself and should always
-   be sent when completed. The scheduler will listen to this message to set the state and unblock
-   dependent jobs. `createJobHandler()` automatically send this message.
-1. `JobOutboundMessageKind.Pong`. The job should answer a `JobInboundMessageKind.Ping` message with
-   this. Automatically done by `createJobHandler()`.
-1. `JobOutboundMessageKind.Output`. An `Output` has been generated by the job.
-1. `JobOutboundMessageKind.ChannelMessage`, `JobOutboundMessageKind.ChannelError` and
-   `JobOutboundMessageKind.ChannelComplete` are used for output channels. These correspond to the
-   `next`, `error` and `complete` methods of an `Observer` and are available to the callee through
-   the `job.channels` map of Observable.
-
-Those messages can be accessed directly through the `job.outboundBus` member. The job itself should
-return an `Observable<JobOutboundMessage<O>>`. The `createJobHandler()` helper handles most of use
-cases of this and makes it easier for jobs to handle this.
-
-## Job Dispatchers
-
-Dispatchers are a helper that redirect to different jobs given conditions. To create a job
-dispatcher, use the `createDispatcher()` function:
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-// A dispatcher that installs node modules given a user's preference.
-const dispatcher = jobs.createDispatcher({
-  name: 'node-install',
-  argument: { properties: { moduleName: { type: 'string' } } },
-  output: { type: 'boolean' },
-});
-
-const npmInstall = jobs.createJobHandler(/* ... */, { name: 'npm-install' });
-const yarnInstall = jobs.createJobHandler(/* ... */, { name: 'yarn-install' });
-const pnpmInstall = jobs.createJobHandler(/* ... */, { name: 'pnpm-install' });
-
-declare const registry: jobs.SimpleJobRegistry;
-registry.register(dispatcher);
-registry.register(npmInstall);
-registry.register(yarnInstall);
-registry.register(pnpmInstall);
-
-// Default to npm.
-dispatcher.setDefaultDelegate(npmInstall.name);
-// If the user is asking for yarn over npm, uses it.
-dispatcher.addConditionalDelegate(() => userWantsYarn, yarnInstall.name);
-```
-
-## Execution Strategy
-
-Jobs are always run in parallel and will always start, but many helper functions are provided
-when creating a job to help you control the execution strategy;
-
-1. `serialize()`. Multiple runs of this job will be queued with each others.
-1. `memoize(replayMessages = false)` will create a job, or reuse the same job when inputs are
-   matching. If the inputs don't match, a new job will be started and its outputs will be stored.
-
-These strategies can be used when creating the job:
-
-```typescript
-// Same input and output as above.
-
-export const add = jobs.strategy.memoize()(
-  jobs.createJobHandler<number[], number>((argument) =>
-    argument.reduce((total, curr) => total + curr, 0),
-  ),
-);
-```
-
-Strategies can be reused to synchronize between jobs. For example, given jobs `jobA` and `jobB`,
-you can reuse the strategy to serialize both jobs together;
-
-```typescript
-const strategy = jobs.strategy.serialize();
-const jobA = strategy(jobs.createJobHandler(...));
-const jobB = strategy(jobs.createJobHandler(...));
-```
-
-Even further, we can have package A and package B run in serialization, and B and C also be
-serialized. Running A and C will run in parallel, while running B will wait for both A and C
-to finish.
-
-```typescript
-const strategy1 = jobs.strategy.serialize();
-const strategy2 = jobs.strategy.serialize();
-const jobA = strategy1(jobs.createJobHandler(...));
-const jobB = strategy1(strategy2(jobs.createJobHandler(...)));
-const jobC = strategy2(jobs.createJobHandler(...));
-```
-
-# Scheduling Jobs
-
-Jobs can be scheduled using a `Scheduler` interface, which contains a `schedule()` method:
-
-```typescript
-interface Scheduler {
-  /**
-   * Schedule a job to be run, using its name.
-   * @param name The name of job to be run.
-   * @param argument The argument to send to the job when starting it.
-   * @param options Scheduling options.
-   * @returns The Job being run.
-   */
-  schedule<I extends MinimumInputValueT, O extends MinimumOutputValueT>(
-    name: JobName,
-    argument: I,
-    options?: ScheduleJobOptions,
-  ): Job<JsonValue, O>;
-}
-```
-
-The scheduler also has a `getDescription()` method to get a `JobDescription` object for a certain
-name; that description contains schemas for the argument, input, output, and other channels:
-
-```typescript
-interface Scheduler {
-  /**
-   * Get a job description for a named job.
-   *
-   * @param name The name of the job.
-   * @returns A description, or null if the job cannot be scheduled.
-   */
-  getDescription(name: JobName): JobDescription | null;
-
-  /**
-   * Returns true if the job name has been registered.
-   * @param name The name of the job.
-   * @returns True if the job exists, false otherwise.
-   */
-  has(name: JobName): boolean;
-}
-```
-
-Finally, the scheduler interface has a `pause()` method to stop scheduling. This will queue all
-jobs and wait for the unpause function to be called before unblocking all the jobs scheduled.
-This does not affect already running jobs.
-
-```typescript
-interface Scheduler {
-  /**
-   * Pause the scheduler, temporary queueing _new_ jobs. Returns a resume function that should be
-   * used to resume execution. If multiple `pause()` were called, all their resume functions must
-   * be called before the Scheduler actually starts new jobs. Additional calls to the same resume
-   * function will have no effect.
-   *
-   * Jobs already running are NOT paused. This is pausing the scheduler only.
-   *
-   * @returns A function that can be run to resume the scheduler. If multiple `pause()` calls
-   *          were made, all their return function must be called (in any order) before the
-   *          scheduler can resume.
-   */
-  pause(): () => void;
-}
-```
-
-## <a name="Dependencies"></a>Synchronizing and Dependencies
-
-When scheduling jobs, it is often necessary to run jobs after certain other jobs are finished.
-This is done through the `dependencies` options in the `schedule()` method.
-
-These jobs will also be passed to the job being scheduled, through its context. This can be
-useful if, for example, the output of those jobs are of a known type, or have known side channels.
-
-An example of this would be a compiler that needs to know the output directory of other compilers
-before it, in a tool chain.
-
-### Dependencies
-
-When scheduling jobs, the user can add a `dependencies` field to the scheduling options. The
-scheduler will wait for those dependencies to finish before running the job, and pass those jobs
-in the context of the job.
-
-### Accessing Dependencies
-
-Jobs are called with a `JobHandlerContext` as a second argument, which contains a
-`dependencies: Job<JsonValue>[]` member which contains all dependencies that were used when
-scheduling the job. Those aren't fully typed as they are determined by the user, and not the job
-itself. They also can contain jobs that are not finished, and the job should use the `state`
-member of the job itself before trying to access its content.
-
-### Scheduler Sub Jobs
-
-The `JobHandlerContext` also contains a `scheduler` member which can be used to schedule jobs
-using the same scheduler that was used for the job. This allows jobs to call other jobs
-and wait for them to end.
-
-## Available Schedulers
-
-The Core Angular DevKit library provides 2 implementations for the `Scheduler` interface:
-
-## SimpleJobRegistry
-
-Available in the jobs namespace. A registry that accept job registration, and can also schedule
-jobs.
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-const add = jobs.createJobHandler<number[], number>((argument) =>
-  argument.reduce((total, curr) => total + curr, 0),
-);
-
-// Register the job in a SimpleJobRegistry. Different registries have different API.
-const registry = new jobs.SimpleJobRegistry();
-const scheduler = new SimpleJobScheduler(registry);
-
-registry.register(add, {
-  name: 'add',
-  argument: { type: 'array', items: { type: 'number' } },
-  output: { type: 'number' },
-});
-
-scheduler.schedule('add', [1, 2, 3, 4]);
-```
-
-## NodeModuleJobRegistry
-
-Available through `@angular-devkit/core/node`.
-
-A scheduler that loads jobs using their node package names. These jobs need to use the
-`createJobHandler()` helper and report their argument/input/output schemas that way.
-
-```typescript
-declare const registry: NodeModuleJobRegistry;
-const scheduler = new SimpleJobScheduler(registry);
-
-scheduler.schedule('some-node-package#someExport', 'input');
-```
-
-# Gotchas
-
-1. Deadlocking Dependencies  
-   It is impossible to add dependencies to an already running job, but it is entirely possible to
-   get locked between jobs. Be aware of your own dependencies.
-
-1. Using `job.promise`  
-   `job.promise` waits for the job to ends. Don't rely on it unless you know the job is not
-   watching and running for a long time. If you aren't sure, use
-   `job.output.pipe(first()).toPromise()` instead which will return the first next output,
-   regardless of whether the job watches and rerun or not.
-
-# FAQ
-
-1. Laziness  
-   A job is lazy until executed, but its messages will be replayed when resubscribed.
-
-1. Serialize Strategy vs Dependencies  
-   Strategies are functions that transform the execution of a job, and can be used when
-   declaring the job, or registering it. Dependencies, on the other hand, are listed when
-   scheduling a job to order jobs during scheduling.
-
-   A job has no control over the way it's scheduled, and its dependencies. It can, however,
-   declare that it shouldn't run at the same time as itself. Alternatively, a user could
-   schedule a job twice and imply that the second run should wait for the first to finish. In
-   practice, this would be equivalent to having the job be serialized, but the important detail
-   is in _whom_ is defining the rules; using the `serialize()` strategy, the job implementation
-   is, while when using dependencies, the user is.
-
-   The user does not need to know how to job needs to synchronize with itself, and the job does
-   not need to know how it synchronizes with other jobs that it doesn't know about. That's part
-   of the strength of this system as every job can be developed in a vacuum, only caring about
-   its contracts (argument, input and output) and its own synchronization.

-# Future Work
-
-Schematics is not done yet. Here's a list of things we are considering:
-
-- Smart defaults for Options. Having a JavaScript function for default values based on other default values.
-- Prompt for input options. This should only be prompted for the original schematics, dependencies to other schematics should not trigger another prompting.
-- Tasks for running tooling-specific jobs before and after a schematics has been scaffolded. Such tasks can involve initialize git, or npm install. A specific list of tasks should be provided by the tool, with unsupported tasks generating an error.

+### Testing
+
+To test locally, install `@angular-devkit/schematics-cli` globally and use the `schematics` command line tool. That tool acts the same as the `generate` command of the Angular CLI, but also has a debug mode.
+
+Check the documentation with
+
+```bash
+schematics --help
+```
+
+### Unit Testing
+
+`npm run test` will run the unit tests, using Jasmine as a runner and test framework.
+
+### Publishing
+
+To publish, simply do:
+
+```bash
+npm run build
+npm publish

+

 # Angular Compiler Webpack Plugin
 
 Webpack 5.x plugin for the Angular Ahead-of-Time compiler. The plugin also supports Angular JIT mode.
+When this plugin is used outside of the Angular CLI, the Ivy linker will also be needed to support
+the usage of Angular libraries. An example configuration of the Babel-based Ivy linker is provided
+in the linker section. For additional information regarding the linker, please see: https://angular.dev/tools/libraries/creating-libraries#consuming-partial-ivy-code-outside-the-angular-cli

@@ -37,4 +42,39 @@ The loader works with webpack plugin to compile the application's TypeScript. It
 - `jitMode` [default: `false`] - Enables JIT compilation and do not refactor the code to bootstrap. This replaces `templateUrl: "string"` with `template: require("string")` (and similar for styles) to allow for webpack to properly link the resources.
 - `directTemplateLoading` [default: `true`] - Causes the plugin to load component templates (HTML) directly from the filesystem. This is more efficient if only using the `raw-loader` to load component templates. Do not enable this option if additional loaders are configured for component templates.
 - `fileReplacements` [default: none] - Allows replacing TypeScript files with other TypeScript files in the build. This option acts on fully resolved file paths.
-- `inlineStyleMimeType` [default: none] - When set to a valid MIME type, enables conversion of an Angular Component's inline styles into data URIs. This allows a Webpack 5 configuration rule to use the `mimetype` condition to process the inline styles. A valid MIME type is a string starting with `text/` (Example for CSS: `text/css`).
+- `inlineStyleFileExtension` [default: none] - When set inline component styles will be processed by Webpack as files with the provided extension.
+
+## Ivy Linker
+
+The Ivy linker can be setup by using the Webpack `babel-loader` package.
+If not already installed, add the `babel-loader` package using your project's package manager.
+Then in your webpack config, add the `babel-loader` with the following configuration.
+If the `babel-loader` is already present in your configuration, the linker plugin can be added to
+the existing loader configuration as well.
+Enabling caching for the `babel-loader` is recommended to avoid reprocessing libraries on
+every build.
+For additional information regarding the `babel-loader` package, please see: https://github.com/babel/babel-loader/tree/main#readme

-An app shell lets Universal render a portion of your application via a route at build time.
-This gives users a meaningful first paint of your application that appears quickly
-because the browser can simply render the HTML without the need to initialize any JavaScript.
-
-Use this command with a routing app that is accompanied by a Universal server-side app.
-
-To create an app shell, use the following command.
-
-<code-example format="." language="bash">
- ng generate app-shell my-app
-</code-example>
-
-- `my-app` is the name of your client application
-- `server-app` is the name of the Universal (server) application
-
-The command adds two new architect build targets to your `angular.json` configuration file (along with a few other changes).
-
-<code-example  format="." language="none" linenums="false">
-"server": {
-  "builder": "@angular-devkit/build-angular:server",
-  "options": {
-    "outputPath": "dist/my-app-server",
-    "main": "src/main.server.ts",
-    "tsConfig": "src/tsconfig.server.json"

-    "browserTarget": "my-app:build",
-    "serverTarget": "my-app:server",
-    "route": "shell"
-  }
-}
-</code-example>
-
-To verify the that the app has been built with the default shell content:
-
-1. Run the app-shell target.
-
-   <code-example format="." language="bash">
-       ng run my-app:app-shell
-    </code-example>
-
-1. Open `dist/app-shell/index.html` in your browser.
-
-The default text "app-shell works!" verifies that the app-shell route was rendered as part of the output.

 # <%= classify(name) %>
 
-This library was generated with [Angular CLI](https://github.com/angular/angular-cli) version <%= angularLatestVersion %>.
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version <%= angularLatestVersion %>.
 
 ## Code scaffolding
 
-Run `ng generate component component-name --project <%= name %>` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module --project <%= name %>`.
-> Note: Don't forget to add `--project <%= name %>` or else it will be added to the default project in your `angular.json` file. 
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
 
-## Build
+```bash
+ng generate component component-name
+```
 
-Run `ng build <%= name %>` to build the project. The build artifacts will be stored in the `dist/` directory.
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
 
-## Publishing
+```bash
+ng generate --help
+```
 
-After building your library with `ng build <%= name %>`, go to the dist folder `cd dist/<%= dasherize(name) %>` and run `npm publish`.
+## Building
+
+To build the library, run:
+
+```bash
+ng build <%= name %>
+```
+
+This command will compile your project, and the build artifacts will be placed in the `dist/` directory.
+
+### Publishing the Library
+
+Once the project is built, you can publish your library by following these steps:
+
+1. Navigate to the `dist` directory:
+   ```bash
+   cd dist/<%= dasherize(name) %>
+   ```
+
+2. Run the `npm publish` command to publish your library to the npm registry:
+   ```bash
+   npm publish
+   ```
 
 ## Running unit tests
 
-Run `ng test <%= name %>` to execute the unit tests via [Karma](https://karma-runner.github.io).
+To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
 
-## Further help
+## Additional Resources
 
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

-    // object that implements the Iterator protocol, in that it has `next`, `return`, and
-    // `throw` methods that step through the generator when invoked.
-    //
-    // parameters:
-    //  @param thisArg  The value to use as the `this` binding for the transformed generator body.
-    //  @param body     A function that acts as the transformed generator body.
-    //
-    // variables:
-    //  _       Persistent state for the generator that is shared between the helper and the
-    //          generator body. The state object has the following members:
-    //            sent() - A method that returns or throws the current completion value.
-    //            label  - The next point at which to resume evaluation of the generator body.
-    //            trys   - A stack of protected regions (try/catch/finally blocks).
-    //            ops    - A stack of pending instructions when inside of a finally block.
-    //  f       A value indicating whether the generator is executing.
-    //  y       An iterator to delegate for a yield*.
-    //  t       A temporary variable that holds one of the following values (note that these
-    //          cases do not overlap):
-    //          - The completion value when resuming from a `yield` or `yield*`.
-    //          - The error value for a catch block.
-    //          - The current protected region (array of try/catch/finally/end labels).
-    //          - The verb (`next`, `throw`, or `return` method) to delegate to the expression
-    //            of a `yield*`.
-    //          - The result of evaluating the verb delegated to the expression of a `yield*`.
-    //
-    // functions:
-    //  verb(n)     Creates a bound callback to the `step` function for opcode `n`.
-    //  step(op)    Evaluates opcodes in a generator body until execution is suspended or
-    //              completed.
-    //
-    // The __generator helper understands a limited set of instructions:
-    //  0: next(value?)     - Start or resume the generator with the specified value.
-    //  1: throw(error)     - Resume the generator with an exception. If the generator is
-    //                        suspended inside of one or more protected regions, evaluates
-    //                        any intervening finally blocks between the current label and
-    //                        the nearest catch block or function boundary. If uncaught, the
-    //                        exception is thrown to the caller.
-    //  2: return(value?)   - Resume the generator as if with a return. If the generator is
-    //                        suspended inside of one or more protected regions, evaluates any
-    //                        intervening finally blocks.
-    //  3: break(label)     - Jump to the specified label. If the label is outside of the
-    //                        current protected region, evaluates any intervening finally
-    //                        blocks.
-    //  4: yield(value?)    - Yield execution to the caller with an optional value. When
-    //                        resumed, the generator will continue at the next label.
-    //  5: yield*(value)    - Delegates evaluation to the supplied iterator. When
-    //                        delegation completes, the generator will continue at the next
-    //                        label.
-    //  6: catch(error)     - Handles an exception thrown from within the generator body. If
-    //                        the current label is inside of one or more protected regions,
-    //                        evaluates any intervening finally blocks between the current
-    //                        label and the nearest catch block or function boundary. If
-    //                        uncaught, the exception is thrown to the caller.
-    //  7: endfinally       - Ends a finally block, resuming the last instruction prior to
-    //                        entering a finally block.
-    //

-        //
-        // When adding more parser context flags, consider which is the more common case that the

-        // that we don't store data in our nodes unless the value is in the *non-default* state.  So,
-        // for example, more often than code 'allows-in' (or doesn't 'disallow-in').  We opt for
-        // 'disallow-in' set to 'false'.  Otherwise, if we had 'allowsIn' set to 'true', then almost
-        // all nodes would need extra state on them to store this info.

-        // Note: 'allowIn' and 'allowYield' track 1:1 with the [in] and [yield] concepts in the ES6
-        // grammar specification.
-        //
-        // An important thing about these context concepts.  By default they are effectively inherited
-        // while parsing through every grammar production.  i.e. if you don't change them, then when
-        // you parse a sub-production, it will have the same context values as the parent production.
-        // This is great most of the time.  After all, consider all the 'expression' grammar productions
-        // and how nearly all of them pass along the 'in' and 'yield' context values:
-        //
-        // EqualityExpression[In, Yield] :
-        //      RelationalExpression[?In, ?Yield]
-        //      EqualityExpression[?In, ?Yield] == RelationalExpression[?In, ?Yield]
-        //      EqualityExpression[?In, ?Yield] != RelationalExpression[?In, ?Yield]
-        //      EqualityExpression[?In, ?Yield] === RelationalExpression[?In, ?Yield]
-        //      EqualityExpression[?In, ?Yield] !== RelationalExpression[?In, ?Yield]
-        //
-        // Where you have to be careful is then understanding what the points are in the grammar
-        // where the values are *not* passed along.  For example:
-        //
-        // SingleNameBinding[Yield,GeneratorParameter]
-        //      [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
-        //      [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt
-        //
-        // Here this is saying that if the GeneratorParameter context flag is set, that we should
-        // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
-        // and we should explicitly unset the 'yield' context flag before calling into the Initializer.
-        // production.  Conversely, if the GeneratorParameter context flag is not set, then we
-        // should leave the 'yield' context flag alone.
-        //
-        // Getting this all correct is tricky and requires careful reading of the grammar to
-        // understand when these values should be changed versus when they should be inherited.
-        //
-        // Note: it should not be necessary to save/restore these flags during speculative/lookahead
-        // parsing.  These context flags are naturally stored and restored through normal recursive
-        // descent parsing and unwinding.

-        //
-        // 1) An error that occurred during scanning.  For example, an unterminated literal, or a
-        //    character that was completely not understood.

-        // 2) A token was expected, but was not present.  This type of error is commonly produced
-        //    by the 'parseExpected' function.
-        //
-        // 3) A token was present that no parsing function was able to consume.  This type of error
-        //    only occurs in the 'abortParsingListOrMoveToNextToken' function when the parser
-        //    decides to skip the token.
-        //

-     * Any module resolution kind can be augmented with optional settings: 'baseUrl', 'paths' and 'rootDirs' - they are used to
-     * mitigate differences between design time structure of the project and its runtime counterpart so the same import name
-     * can be resolved successfully by TypeScript compiler and runtime module loader.
-     * If these settings are set then loading procedure will try to use them to resolve module name and it can of failure it will
-     * fallback to standard resolution routine.
-     *
-     * - baseUrl - this setting controls how non-relative module names are resolved. If this setting is specified then non-relative
-     * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will
-     * be '/a/b/c/d'
-     * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names
-     * will be resolved based on the content of the module name.
-     * Structure of 'paths' compiler options
-     * 'paths': {
-     *    pattern-1: [...substitutions],
-     *    pattern-2: [...substitutions],
-     *    ...
-     *    pattern-n: [...substitutions]
-     * }
-     * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against
-     * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case.
-     * If pattern contains '*' then to match pattern "<prefix>*<suffix>" module name must start with the <prefix> and end with <suffix>.
-     * <MatchedStar> denotes part of the module name between <prefix> and <suffix>.
-     * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked.
-     * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module
-     * from the candidate location.
-     * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every
-     * substitution in the list and replace '*' with <MatchedStar> string. If candidate location is not rooted it
-     * will be converted to absolute using baseUrl.
-     * For example:
-     * baseUrl: /a/b/c
-     * "paths": {
-     *     // match all module names
-     *     "*": [
-     *         "*",        // use matched name as is,
-     *                     // <matched name> will be looked as /a/b/c/<matched name>
-     *
-     *         "folder1/*" // substitution will convert matched name to 'folder1/<matched name>',
-     *                     // since it is not rooted then final candidate location will be /a/b/c/folder1/<matched name>
-     *     ],
-     *     // match module names that start with 'components/'
-     *     "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/<matched name> to '/root/components/folder1/<matched name>',
-     *                                              // it is rooted so it will be final candidate location
-     * }
-     *
-     * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if
-     * they were in the same location. For example lets say there are two files
-     * '/local/src/content/file1.ts'
-     * '/shared/components/contracts/src/content/protocols/file2.ts'
-     * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so
-     * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime.
-     * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all
-     * root dirs were merged together.
-     * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
-     * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:
-     * '/local/src/content/protocols/file2' and try to load it - failure.
-     * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
-     * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining
-     * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.

-
-                  In the default clause we de not compute an implied type.
-
-                  In the third clause (case `number` and `boolean`)
-                  the naive implied type is number | boolean, however
-                  we use the type facts to narrow the implied type to
-                  boolean. We know that number cannot be selected

-//
-//  .nop                            - Performs no operation.
-//  .local NAME, ...                - Define local variable declarations.
-//  .mark LABEL                     - Mark the location of a label.
-//  .br LABEL                       - Jump to a label. If jumping out of a protected
-//                                    region, all .finally blocks are executed.
-//  .brtrue LABEL, (x)              - Jump to a label IIF the expression `x` is truthy.
-//                                    If jumping out of a protected region, all .finally
-//                                    blocks are executed.

-//  .yield (x)                      - Yield the value of the optional expression `x`.
-//                                    Resume at the next label.
-//  .yieldstar (x)                  - Delegate yield to the value of the optional
-//                                    expression `x`. Resume at the next label.
-//                                    NOTE: `x` must be an Iterator, not an Iterable.
-//  .loop CONTINUE, BREAK           - Marks the beginning of a loop. Any "continue" or
-//                                    "break" abrupt completions jump to the CONTINUE or
-//                                    BREAK labels, respectively.
-//  .endloop                        - Marks the end of a loop.
-//  .with (x)                       - Marks the beginning of a WithStatement block, using
-//                                    the supplied expression.
-//  .endwith                        - Marks the end of a WithStatement.
-//  .switch                         - Marks the beginning of a SwitchStatement.
-//  .endswitch                      - Marks the end of a SwitchStatement.
-//  .labeled NAME                   - Marks the beginning of a LabeledStatement with the
-//                                    supplied name.
-//  .endlabeled                     - Marks the end of a LabeledStatement.
-//  .try TRY, CATCH, FINALLY, END   - Marks the beginning of a protected region, and the
-//                                    labels for each block.
-//  .catch (x)                      - Marks the beginning of a catch block.

-//  .return (x)                     - Returns the value of the expression `x`.
-//
-// In addition, the illustrative intermediate representation introduces some special
-// variables:
-//
-//  %sent%                          - Either returns the next value sent to the generator,
-//                                    returns the result of a delegated yield, or throws
-//                                    the exception sent to the generator.
-//  %error%                         - Returns the value of the current exception in a
-//                                    catch block.
-//
-// This intermediate representation is then compiled into JavaScript syntax. The resulting
-// compilation output looks something like the following:
-//
-//  function f() {
-//      var /*locals*/;
-//      /*functions*/
-//      return __generator(function (state) {
-//          switch (state.label) {
-//              /*cases per label*/
-//          }
-//      });
-//  }

-             * ```js

-             * |    Symbols to    |      | Aliases to symbols   |      | Symbols to return |
-             * |    definitely    |      | in Buckets A or C    |      | if nothing better |
-             * |      return      |      | (don’t return these) |      |    comes along    |
-             * |__________________|      |______________________|      |___________________|
-             * ```
-             *
-             * We _probably_ want to show `foo` from 'x', but not from 'y' or 'z'. However, if 'x' is not in a package.json, it
-             * will not appear in a `forEachExternalModuleToImportFrom` iteration. Furthermore, the order of iterations is not
-             * guaranteed, as it is host-dependent. Therefore, when presented with the symbol `foo` from module 'y' alone, we
-             * may not be sure whether or not it should go in the list. So, we’ll take the following steps:
-             *
-             * 1. Resolve alias `foo` from 'y' to the export declaration in 'x', get the symbol there, and see if that symbol is
-             *    already in Bucket A (symbols we already know will be returned). If it is, put `foo` from 'y' in Bucket B
-             *    (symbols that are aliases to symbols in Bucket A). If it’s not, put it in Bucket C.
-             * 2. Next, imagine we see `foo` from module 'z'. Again, we resolve the alias to the nearest export, which is in 'y'.
-             *    At this point, if that nearest export from 'y' is in _any_ of the three buckets, we know the symbol in 'z'
-             *    should never be returned in the final list, so put it in Bucket B.
-             * 3. Next, imagine we see `foo` from module 'x', the original. Syntactically, it doesn’t look like a re-export, so
-             *    we can just check Bucket C to see if we put any aliases to the original in there. If they exist, throw them out.
-             *    Put this symbol in Bucket A.
-             * 4. After we’ve iterated through every symbol of every module, any symbol left in Bucket C means that step 3 didn’t
-             *    occur for that symbol---that is, the original symbol is not in Bucket A, so we should include the alias. Move
-             *    everything from Bucket C to Bucket A.

-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version <%= version %>.
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version <%= version %>.
 
 ## Development server
 
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
 
 ## Code scaffolding
 
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
 
-## Build
+## Building
 
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
 
 ## Running unit tests
 
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+To execute unit tests with the [Vitest](https://vitest.dev/) test runner, use the following command:
+
+```bash
+ng test
+```
 
 ## Running end-to-end tests
 
-Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
 
-## Further help
+## Additional Resources
 
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

-## changelog
-
-Creates a changelog draft in GitHub releases.
-
-Flags:
-
-- `--from=<git-ref>`. **[Required]** The git ref (SHA, tag or ref) to start the CHANGELOG at.
-- `--to=<tag>`. **[Required]** The git ref (tag) to end the CHANGELOG at. This will also be used to name the changelog
-  on GitHub.
-- `--githubToken=<string>`. The github token to update the changelog with. If this is not specified, the release notes
-  will be outputted to stdout.
-- `--githubTokenFile=<path>`. Reads the githubToken from a file instead of the command line (for CI).
-- `--stdout`. Skip the whole release note process and output the markdown to stdout instead.
-
 ## packages
 
 Outputs a JSON containing all informations from the package script (main files, repo names, versions, deps, etc).
 
-## publish
-
-Builds and published the packages to npm.
-
-Flags:
-
-- `--tag=<name>`. Publishes under the npm dist-tag specified.
-
-## release
-
-General version and release manager.
-
-Usage:
-
-```bash
-$ devkit-admin release
-```
-
-Outputs all the packages, their versions and their hashes. By default, excludes private packages that are only used in
-the repo (such as private schematics). With the `--verbose` flag will output the private packages as well.
-
-By adding a command, the `release` script will update the version;
-
-- `major-beta`. Set the version of packages to the next beta of the next major.
-- `major-rc`. Set the version of packages to the next RC of the next major.
-- `major`. Increment the major version of packages.
-- `minor-beta`. Set the version of packages to the next beta of the next minor.
-- `minor-rc`. Set the version of packages to the next RC of the next minor.
-- `minor`. Increment the minor version of packages.
-- `patch`. Increment the patch version of packages.
-
-By default, the release script will increment versions of packages that have changed. Use the `--force` flag to change
-the version of all packages, even those who haven't changed.
-
-e.g.
-
-```bash
-$ devkit-admin release minor-beta --force
-```
-
 ## snapshots
 
 Create and upload snapshots. This is used in CI.

-## <a name="public-api"></a> Updating the Public API
-Our Public API is protected with TS API Guardian. This is a tool that keeps track of public API surface of our packages.
-
-To test if your change effect the public API you need to run the API guardian on that particular package.
-
-For example in case `@angular-devkit/core` package was modified you need to run:
-
-```bash
-yarn bazel test //goldens/public-api:angular_devkit_core_api
-```
-
-You can also test all packages by running:
-```bash
-yarn bazel test //goldens/public-api ...
-```
-
-If you modified the public API, the test will fail. To update the golden files you need to run:
-
-```bash
-yarn bazel run //goldens/public-api:angular_devkit_core_api.accept
-```
-
-**Note**: In some cases we use aliased symbols to create namespaces.
-
-Example:
-```javascript
-import * as foo from './foo';
-
-export { foo };
-```
-There are currently not supported by the API guardian.
-To overcome this limitation we created `_golden-api.ts` in certain packages.
+[stackoverflow]: https://stackoverflow.com/questions/tagged/angular-devkit
 
-When adding a new API, it might be the case that you need to add it to `_golden-api.ts`.

-## The Goal of Angular CLI
+<hr>
 
-The Angular CLI creates, manages, builds and test your Angular projects. It's built on top of the
-Angular DevKit.
+## Documentation
 
-## The Goal of DevKit
+Get started with Angular CLI, learn the fundamentals and explore advanced topics on our documentation website.
 
-DevKit's goal is to provide a large set of libraries that can be used to manage, develop, deploy and
-analyze your code.
+- [Getting started][quickstart]
+- [CLI][cli]
+- [Workspace and project file structure][filestructure]
+- [Workspace configuration][workspaceconfig]
+- [Schematics][schematics]
 
-# Getting Started - Local Development
+## Development Setup
 
-## Installation
 
-To get started locally, follow these instructions:
+### Prerequisites
 
-1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
-1. Clone to your local computer using `git`.
-1. Make sure that you have Node 12.14 or 14.0 installed. See instructions [here](https://nodejs.org/en/download/).
-1. Make sure that you have `yarn` installed; see instructions [here](https://yarnpkg.com/lang/en/docs/install/).
-1. Run `yarn` (no arguments) from the root of your clone of this project to install dependencies.
+- Install [Node.js] which includes [Node Package Manager][npm]
 
-## Building and Installing the CLI
+### Setting Up a Project
 
-To make a local build:
+Install the Angular CLI globally:
 
-```shell
-yarn build --local
+```
+npm install -g @angular/cli
 ```
 
-This generates a number of tarballs in the `dist/` directory. To actually use
-the locally built tools, switch to another repository reproducing the specific
-issue you want to fix (or just generate a local repo with `ng new`). Then
-install the locally built packages:
+Create workspace:
 
-```shell
-cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
-npm install -D ${CLI_REPO}/dist/*.tgz
+```
+ng new [PROJECT NAME]
 ```
 
-Builds of this example project will use tooling created from the previous local
-build and include any local changes. When using the CLI, it will automatically
-check for a local install and use that if present. This means you can just run:
+Run the application:
 
-```shell
-npm install -g @angular/cli
+```
+cd [PROJECT NAME]
+ng serve
 ```
 
-to get a global install of the latest CLI release. Then running any `ng` command
-in the example project will automatically find and use the local build of the
-CLI.
+Angular is cross-platform, fast, scalable, has incredible tooling, and is loved by millions.
 
-Note: If you are testing `ng update`, be aware that installing all the tarballs
-will also update the framework (`@angular/core`) to the latest version. In this
-case, simply install the CLI alone with
-`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
-project remains to be upgraded with `ng update`.
+## Quickstart
 
-## Debugging
+[Get started in 5 minutes][quickstart].
 
-To debug an invocation of the CLI, [build and install the CLI for an example
-project](#building-and-installing-the-cli), then run the desired `ng` command
-as:
+## Ecosystem
 
-```shell
-node --inspect-brk node_modules/.bin/ng ...
-```
+<p>
+  <img src="/docs/images/angular-ecosystem-logos.png" alt="angular ecosystem logos" width="500px" height="auto">
+</p>
 
-This will trigger a breakpoint as the CLI starts up. You can connect to this
-using the supported mechanisms for your IDE, but the simplest option is to open
-Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
-link for the `node_modules/.bin/ng` Node target.
+- [Angular Framework][adev]
+- [Angular Material][angularmaterial]
 
-Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
-the debugger is not aware of all the source code files before hand. As a result,
-it is tough to put breakpoints on files before the CLI loads them. The easiest
-workaround is to use the `debugger;` statement to stop execution in the file you
-are interested in, and then you should be able to step around and set breakpoints
-as expected.
+## Changelog
 
-## Testing
+[Learn about the latest improvements][changelog].
 
-There are two different test suites which can be run locally:
+## Upgrading
 
-### Unit tests
-  * Run all tests: `yarn bazel test //packages/...`
-  * Run a subset of the tests, use the full Bazel target example: `yarn bazel test //packages/schematics/angular:angular_test`
-  * For a complete list of test targets use the following Bazel query: `yarn bazel query "tests(//packages/...)"`
+Check out our [upgrade guide](https://update.angular.dev/) to find out the best way to upgrade your project.
 
-You can find more info about debugging [tests with Bazel in the docs.](https://github.com/angular/angular-cli/blob/master/docs/process/bazel.md#debugging-jasmine_node_test)  
+## Contributing
 
-### End to end tests
-  * Run: `node tests/legacy-cli/run_e2e.js`
-  * Run a subset of the tests: `node tests/legacy-cli/run_e2e.js tests/legacy-cli/e2e/tests/i18n/ivy-localize-*`
+### Contributing Guidelines
 
-When running the debug commands, Node will stop and wait for a debugger to attach.
-You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also, see [IDE Specific Usage](#ide-specific-usage) for a
-simpler debug story.
+Read through our [contributing guidelines][contributing] to learn about our submission process, coding rules and more.
 
-When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
-and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.

Read up on our guidelines for [contributing][contributing] and then check out one of our issues labeled as <kbd>[help wanted](https://github.com/angular/angular-cli/labels/help%20wanted)</kbd> or <kbd>[good first issue](https://github.com/angular/angular-cli/labels/good%20first%20issue)</kbd>.
 
-Some additional tips for developing in specific IDEs.
+### Code of Conduct
 
-### Intellij IDEA / WebStorm
+Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][codeofconduct].
 
-To load the project in Intellij products, simply `Open` the repository folder.
-Do **not** `Import Project`, because that will overwrite the existing
-configuration.
+### Developer Guide
 
-Once opened, the editor should automatically detect run configurations in the
-workspace. Use the drop down to choose which one to run and then click the `Run`
-button to start it. When executing a debug target, make sure to click the
-`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
-wait forever for a debugger to attach).
+Read through our [developer guide][developer] to learn about how to build and test the Angular CLI locally.

-## Creating New Packages
+## Community
 
-Adding a package to this repository means running two separate commands:
+Join the conversation and help the community.
 
-1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
-  base files for the new package (package.json, src/index, etc).
-1. `devkit-admin templates`. This will update the README and all other template files that might
-  have changed when adding a new package.
+- [X (formerly Twitter)][twitter]
+- [Discord][discord]
+- [Gitter][gitter]
+- [YouTube][youtube]
+- [StackOverflow][stackoverflow]
+- Find a Local [Meetup][meetup]
 
-For private packages, you will need to add a `"private": true` key to your package.json manually.
-This will require re-running the template admin script.

+# NineteenProject
+
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 19.2.13.
+
+## Development server
+
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+
+## Code scaffolding
+
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
+
+## Building
+
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
+
+## Running unit tests
+
+To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
+
+## Additional Resources
+
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

+# 17SsrProjectWebpack
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 16.2.10.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The application will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate --help` to see all the available schematics you can generate.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview](https://angular.dev/tools/cli) and [Command Reference](https://angular.dev/cli) pages.

- * Here's a short description of those flags:
- *   --debug          If a test fails, block the thread so the temporary directory isn't deleted.
- *   --noproject      Skip creating a project or using one.
- *   --nobuild        Skip building the packages. Use with --noglobal and --reuse to quickly
- *                    rerun tests.
- *   --noglobal       Skip linking your local @angular/cli directory. Can save a few seconds.
- *   --nosilent       Never silence ng commands.
- *   --ng-tag=TAG     Use a specific tag for build snapshots. Similar to ng-snapshots but point to a
- *                    tag instead of using the latest master.
- *   --ng-snapshots   Install angular snapshot builds in the test project.
- *   --ve             Use the View Engine compiler.
- *   --glob           Run tests matching this glob pattern (relative to tests/e2e/).
- *   --ignore         Ignore tests matching this glob pattern.
- *   --reuse=/path    Use a path instead of create a new project. That project should have been
- *                    created, and npm installed. Ideally you want a project created by a previous
- *                    run of e2e.
- *   --nb-shards      Total number of shards that this is part of. Default is 2 if --shard is
- *                    passed in.
- *   --shard          Index of this processes' shard.
- *   --devkit=path    Path to the devkit to use. The devkit will be built prior to running.
- *   --tmpdir=path    Override temporary directory to use for new projects.
- * If unnamed flags are passed in, the list of tests will be filtered to include only those passed.
