A WebSub hub, publisher and subscriber using Flask
An implementation of a WebSub hub, publisher and subscriber as a Flask extension. The implementation is meant to be used as a library that can be integrated in a larger application.
The components are split up into multiple packages, so you don’t necessarily have to use all three. It is for example possible to use the subscriber implementation with an external hub. To learn to use this package, take a look at the client_example.py (subscriber) and server_example.py (hub/publisher) files. See the documentation for further information: https://flask-websub.readthedocs.io/
Using the flask_websub.hub package requires celery.
