How do channels work in Django?

Channels Layers In Django Channel Layers allow us to create interaction between different instances of an application , mostly used to create real-time applications, we can say it’s an alternative to sockets.

With WebSockets (via Django Channels) managing the communication between the client and the server, whenever a user is authenticated, an event will be broadcasted to every other connected user . Each user’s screen will change automatically, without them having to reload their browsers.

Django Channels facilitates support of WebSockets in Django in a manner similar to traditional HTTP views . It wraps Django’s native asynchronous view support, allowing Django projects to handle not only HTTP, but also protocols that require long-running connections, such as WebSockets, MQTT, chatbots, etc.

Channels preserve the synchronous behavior of Django and add a layer of asynchronous protocols allowing users to write the views that are entirely synchronous, asynchronous, or a mixture of both . Channels basically allow the application to support “long-running connections”.
