Django Private Chat2

Chat app for Django, powered by Django Channels, Websockets & Asyncio

Documentation

The full documentation will be at https://django_private_chat2.readthedocs.io.

Quickstart

Install django_private_chat2:

pip install django_private_chat2

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'django_private_chat2.apps.DjangoPrivateChat2Config',
    ...
)

Add django_private_chat2's URL patterns:

from django_private_chat2 import urls as django_private_chat2_urls


urlpatterns = [
    ...
    url(r'^', include(django_private_chat2_urls)),
    ...
]

Add django_private_chat2's websocket URLs to your asgi.py:


django_asgi_app = get_asgi_application()
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from django_private_chat2 import urls
application = ProtocolTypeRouter({
    "http": django_asgi_app,
    "websocket": AuthMiddlewareStack(
        URLRouter(urls.websocket_urlpatterns)
    ),
})

Important:

django_private_chat2 doesn't provide any endpoint to fetch users (required to start new chat, for example)
It's up to you to do so. The example app does it in urls.py so feel free to copy the handler from there if you wish.

Support

django_private_chat2 is tested against python3.6, python3.7, python3.8, python3.9 with Django 3.0, Django 3.1 and Django 3.2.
