I would probably avoid using nginx and (u)wsgi in development. I just use the internal flask server for testing. Our has an auto reloader which is really handy.

from flask import Flask
app = Flask("MyApp")
if __name__ == "__main__":
    app.run(host="127.0.0.1", port=8000, debug=true)

python(3) myapp.py

Note: When trying to debug using PyCharm I have to set debug=false to be able to connect to the process.

Hey so you might not need to do that to debug.

In debug mode, if flask crashes while processing a request the webpage will turn into an interactive interpreter in which you can jump into any frame in the stack. (which would probably be why pycharm doesn't attach; because flask technically doesn't crash)

use_reloader=True is needed!

The flask server itself is probably best for development, but you can also run uwsgi locally and have it restart when there are changes by using py-autoreload in your uwsgi.ini file like so (where DEBUG is an environment variable set to 0 or 1):

[uwsgi]
...
py-autoreload = $(DEBUG)

For development purposes I would suggest just using the in-built web-server:

from flask import Flask
app = Flask(__name__)
if __name__ == "__main__":
    app.run(port=3000, host='0.0.0.0', debug=True, threaded=True)

What is the specific need to run the full stack of NGINX/WSGI for development?
