How to debug a Flask app

Question

How are you meant to debug errors in Flask? Print to the console? Flash messages to the page? Or is there a more powerful option available to figure out what\'s happening

Answer 1

For Windows users:

Open Powershell and cd into your project directory.

Use these commandos in Powershell, all the other stuff won't work in Powershell.

$env:FLASK_APP = "app"  
$env:FLASK_ENV = "development"
