Using WhiteNoise with Flask¶
This guide walks you through setting up a Flask project with WhiteNoise. In most cases it shouldn’t take more than a couple of lines of configuration.
1. Make sure where your static is located¶
If you’re familiar with Flask you’ll know what to do. If you’re just getting
started with a new Flask project then the default is the
static folder in
the root path of the application.

2. Enable WhiteNoise¶
In the file where you create your app you instantiate Flask Application Object
flask.Flask() object). All you have to do is to wrap it with
If you use Flask quick start approach it will look something like that:
from flask import Flask from whitenoise import WhiteNoise app = Flask(__name__) app.wsgi_app = WhiteNoise(app.wsgi_app, root='static/')
If you opt for the pattern of creating your app with a function, then it would look like that:
from flask import Flask from sqlalchemy import create_engine from whitenoise import WhiteNoise from myapp import config from myapp.views import frontend def create_app(database_uri, debug=False): app = Flask(__name__) app.debug = debug # set up your database app.engine = create_engine(database_uri) # register your blueprints app.register_blueprint(frontend) # add whitenoise app.wsgi_app = WhiteNoise(app.wsgi_app, root='static/') # other setup tasks return app
That’s it – WhiteNoise will now serve your static files.
3. Custom static folder¶
If it turns out that you are not using the Flask default for static folder, fear not. You can instantiate WhiteNoise and add your static folders later:
from flask import Flask from whitenoise import WhiteNoise app = Flask(__name__) app.wsgi_app = WhiteNoise(app.wsgi_app) my_static_folders = ( 'static/folder/one/', 'static/folder/two/', 'static/folder/three/' ) for static in my_static_folders: app.wsgi_app.add_files(static)
