The Sequence SDK is available via npm. Node 4 or greater is required.

To install, add the sequence-sdk NPM module to your package.json:

{"dependencies":{"sequence-sdk": "~2.2.4" } }

If you're using TypeScript, include the following in your tsconfig.json:

{"compilerOptions":{"lib": ["es2015", "es2016", "esnext"], "types": ["node"] } }

Also, run:

npm i --save-dev @types/node 

constsequence=require('sequence-sdk')constledger=newsequence.Client({ledgerName: 'ledger',credential: '...',})

Most SDK methods return Promise objects, which you can use with async/await, or consume directly.

With async/await:

asyncfunctionmain(){try{constaccount=awaitledger.accounts.create({...})// operate on account}catch(err){// handle errors}}

With the Promise object itself:

functionmain(){returnledger.accounts.create({...}).then(account=>{// operate on account}).catch(err=>{// handle errors})}

Comprehensive instructions and examples are available in the developer documentation.
