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.

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.
