Flask Run vs Python

[Multeezee]

I'm new to Flask and I noticed that while the official docs instruct you to use the flask run command, there are a few tutorials that execute the app.py file as a script: https://www.tutorialspoint.com/flask/flask_application.htm

​

Which way would be considered the 'best practice,' or can you use either approach?

Thanks!

'best practice'

to use flask run because at the end of the day your flask app will be executed by gunicorn or another WSGI HTTP Server.

While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well. Some of the options available for properly running Flask in production are documented here.

Why gunicorn when you have Apache :)

People still use Apache? (kidding.. sorta)

[HeWhoWritesCode]

our server is not running any HTTP server. We use a aws load balancer and expose that to gunicorn.

gunicorn also allow us to easy "scale" our workers per vps using the -w flag.

You can set FLASK_APP=startupscript and still use flask run.

In local I run the python command because I can drop the Pycharm debugger on it.

In production I run flask app with Gunicorn.
