Quart-Flask-Patch is a Quart extension that patches Quart to work with Flask extensions.

Quart-Flask-Patch

Quart-Flask-Patch is a Quart extension that patches Quart to work with Flask extensions.

Quickstart

Quart-Flask-Patch must be imported first in your main module, so that the patching occurs before any other code is initialised. For example, if you want to use Flask-Login,

.. code-block:: python

import quart_flask_patch

from quart import Quart import flask_login

app = Quart(name) login_manager = flask_login.LoginManager() login_manager.init_app(app)

Extensions known to work

The following flask extensions are tested and known to work with quart,

Flask-BCrypt <https://flask-bcrypt.readthedocs.io>_
Flask-Caching <https://flask-caching.readthedocs.io>_
Flask-KVSession <https://github.com/mbr/flask-kvsession>_
Flask-Limiter <https://github.com/alisaifee/flask-limiter/>_ See also Quart-Rate-Limiter <https://github.com/pgjones/quart-rate-limiter>_
Flask-Login <https://github.com/maxcountryman/flask-login/>_ See also Quart-Login <https://github.com/0000matteo0000/quart-login>_ or Quart-Auth <https://github.com/pgjones/quart-auth>_
Flask-Mail <https://pythonhosted.org/Flask-Mail/>_
Flask-Mako <https://pythonhosted.org/Flask-Mako/>_
Flask-Seasurf <https://github.com/maxcountryman/flask-seasurf/>_
Flask-SQLAlchemy <https://flask-sqlalchemy.palletsprojects.com>_ See also Quart-DB <https://github.com/pgjones/quart-db>_
Flask-WTF <https://flask-wtf.readthedocs.io>_

Extensions known not to work

The following flask extensions have been tested are known not to work with quart,

Flask-CORS <https://github.com/corydolphin/flask-cors>, as it uses app.make_response which must be awaited. Try Quart-CORS <https://github.com/pgjones/quart-cors> instead.
Flask-Restful <https://flask-restful.readthedocs.io>_ as it subclasses the Quart (app) class with synchronous methods overriding asynchronous methods. Try Quart-OpenApi <https://github.com/factset/quart-openapi/>_ or Quart-Schema <https://github.com/pgjones/quart-schema>_ instead.

Caveats

Flask extensions must use the global request proxy variable to access the request, any other access e.g. via ~quart.local.LocalProxy._get_current_object will require asynchronous access. To enable this the request body must be fully received before any part of the request is handled, which is a limitation not present in vanilla flask.

Trying to use Flask alongside Quart in the same runtime will likely not work, and lead to surprising errors.

The flask extension must be limited to creating routes, using the request and rendering templates. Any other more advanced functionality may not work.

Synchronous functions will not run in a separate thread (unlike Quart normally) and hence may block the event loop.

Finally the flask_patching system also relies on patching asyncio, and hence other implementations or event loop policies are unlikely to work.

Testing


The best way to test Quart-Flask-Patch is with `uv
<https://docs.astral.sh/uv/>`_,

.. code-block:: console

    $ uv run --group test pytest --cov=quart_flask_patch
    $ uv run --group format black --check --diff src/quart_flask_patch/ tests/
    $ uv run --group format isort --check --diff src/quart_flask_patch/ tests
    $ uv run --group pep8 flake8 src/quart_flask_patch/ tests/
    $ uv run --group typing mypy src/quart_flask_patch/

this will run the tests and check the code style.
