How to make online notifications in Django?

Question

Django

Hello!
I would like to make messages on the site like Vkontakte, so that the user sees new messages without refreshing the page!
As I understand it, all this is done using WebSocket (socket.io), tell me how best to do this and which way to look ?!

Answer 1

ajax after 2 seconds requests the url, if something has arrived - displays
if you bother - event source

Websockets should be used if you need to send an almost real-time notification stream

Answer 2

Dzhanga is not designed for such things, look better towards Tornado + SocksJS.
