Websockets for Django using Redis as message queue

This module implements websockets on top of Django without requiring any additional framework. For messaging it uses the [Redis](http://redis.io/) datastore and in a production environment, it is intended to work under [uWSGI](http://projects.unbit.it/uwsgi/) and behind [NGiNX](http://nginx.com/).

New in 0.4.2

  • Message echoing can be switched “on” and “off” according to the user needs. Before it was “on” by default.
  • Many changes to become compatible with Python3; there are still minor issues to solve.
  • The message string to be passed and stored to and from the websocket hase been converted into a class RedisMessage for type saftey.

Features

  • Largely scalable for Django applications with hundreds of open websocket connections.
  • Runs in a cooperative concurrency model using [gevent](http://www.gevent.org/), thus only one thread/process is simultaneously required to control all open websockets.
  • Full control over the main loop during development, so Django can be started as usual with ./manage.py runserver.
  • No dependency to any other asynchronous event driven framework, such as Tornado, Twisted or Node.js.
  • Optionally persiting messages, allowing server reboots and client reconnections.
  • The only additional requirement is a running instance of Redis, which by the way is a good replacement for memcached.

If unsure, if this proposed architecture is the correct approach on how to integrate websockets with Django, then please read Roberto De Ioris article about [Offloading Websockets and Server-Sent Events AKA “Combine them with Django safely”](http://uwsgi-docs.readthedocs.org/en/latest/articles/OffloadingWebsocketsAndSSE.html).
