Modern Flask (3.x) Best Practices

  • Use flask run instead of app.run()
  • Use Application Factories
from flask import Flask


def create_app(test_config=None):
    # create and configure the app
    app = Flask(__name__, instance_relative_config=True)
    app.config.from_mapping(
        SECRET_KEY="dev",
    )

    if test_config is None:
        # load the instance config, if it exists, when not testing
        app.config.from_pyfile("config.py", silent=True)
    else:
        # load the test config if passed in
        app.config.from_mapping(test_config)

    # a simple page that says hello
    @app.route("/hello")
    def hello():
        return "Hello, World!"

    return app
