I've been running into an increasing need for JS push notifications and have played with a few ways of doing it. Recently ran across Pusher API. They use a combo of HTML5 websockets & flash fallbacks. Much easier than Comet, etc.

But their python library didn't support presence. Here's everything you need to make presence work in Django, including an updated library.

My JS


var pusher = new Pusher('MY_PUBLIC_KEY');
Pusher.channel_auth_endpoint = '/api/pusher/auth/'
var channel = pusher.subscribe('presence-meeting-1')
