Starting this App with Flask is slow, it takes a few seconds to load

[Alan3344]

Here is the simple test code

• This phenomenon did not occur when I used Fastapi
• I don't know about other frameworks without testing

# index_flask.pyfromreactpyimportcomponent, html@componentdefIndex(): returnhtml.div( html.h1('Test Flask App'), html.h2('Hello World'), )

# main-flask.pyfromindex_flaskimportIndexfromreactpy.backend.flaskimportconfigure, Flaskapp=Flask(__name__) app.config['debug'] =Trueconfigure(app, Index) print(app.url_map)

default at http://127.0.0.1:8000

# startup it gunicorn main-flask:app --reload

• Running this for the first time will output
