Django Channels

Channels is a project to make Django able to handle more than just plain HTTP requests, including WebSockets and HTTP2, as well as the ability to run code after a response has been sent for things like thumbnailing or background calculation.

It’s an easy-to-understand extension of the Django view model, and easy to integrate and deploy.

First, read our Channels Concepts documentation to get an idea of the data model underlying Channels and how they’re used inside Django.

Then, read Getting Started with Channels to see how to get up and running with WebSockets with only 30 lines of code.

Projects

Channels is comprised of five packages:

  • Channels, the Django integration layer

  • Daphne, the HTTP and Websocket termination server

  • asgiref, the base ASGI library/memory backend

  • asgi_redis, the Redis channel backend

  • asgi_ipc, the POSIX IPC channel backend

This documentation covers the system as a whole; individual release notes and instructions can be found in the individual repositories.
