Django Socket Server

Quickstart

1. Install django-socket-server:

   pip install django-socket-server
   

2. Add socket_server to INSTALLED_APPS:

   INSTALLED_APPS = (
       ...
       'socket_server',
       ...
   )
   

Create a sockets.py in an application of your project.

django-socket-server will discover the socket files that are in applications installed against Django.

An example sockets.py looks like this:

from socket_server.namespace import EventNamespace


class Namespace(EventNamespace):

    def client_connected(self, client):
        super(Namespace, self).client_connected(client)

        print 'Send ping'
        self.emit_to(client, 'ping')

    def register_callbacks(self):
        return {
            'pong': self.pong
        }

    def pong(self, client, **kwargs):
        print 'Received pong event'

Messages are sent and received in JSON, and always contain an event key. This key is then mapped to callbacks, added inside register_callbacks.

You can specify a namespace name using the name property like so:

class Namespace(EventNamespace):
    name = 'pingpong'

If you do not specify a name, the app name will be used by default.

Start Socket Server

Use the management command provided to start the socket server: python manage.py start_socket.

You may pass an optional --port to override the default port of 3000.

Client connection

The above example would expose the following: ws://localhost:3000/pingpong
