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 datastore and in a production environment, it is intended to work under uWSGI and behind NGiNX.

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, 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”.
