Channels

Channels is a Django extension that enables handling of asynchronous protocols like WebSockets, HTTP/2, and other real-time communication in Django applications. It provides a layer that allows Django to handle connections that are long-lived and require bidirectional communication, extending Django's request/response model to support real-time features. It integrates with Django's ORM and authentication system while using ASGI (Asynchronous Server Gateway Interface) as its underlying protocol.

Also known as: Django Channels, Channels Framework, Django-Channels, ASGI Channels, Channels for Django

Why learn Channels?

Developers should learn Channels when building Django applications that require real-time functionality such as live chat, notifications, collaborative editing, or gaming features, as it seamlessly integrates with Django's ecosystem. It is particularly useful for projects where WebSocket support is needed alongside traditional HTTP requests, allowing for efficient handling of concurrent connections without blocking the main application flow. Use it when you need to extend a Django app with asynchronous capabilities while maintaining Django's structure and tools.
