Flask Debug-toolbar

This is a port of the excellent django-debug-toolbar for Flask applications.



Installing is simple with pip:

$ pip install flask-debugtoolbar


Setting up the debug toolbar is simple:

from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension

app = Flask(__name__)

# the toolbar is only enabled in debug mode:
app.debug = True

# set a 'SECRET_KEY' to enable the Flask session cookies
app.config['SECRET_KEY'] = '<replace with a secret key>'

toolbar = DebugToolbarExtension(app)

The toolbar will automatically be injected into Jinja templates when debug mode is on. In production, setting app.debug = False will disable the toolbar.

See the documentation for more information.
