Complete the setup by updating INSTALLED_APPS in the project’s settings.py file: Then Configure the CHANNEL_LAYERS by setting a default backend and routing:
How does the Websockets protocol work in Django?
Django parses the request, extracts a URL, and then matches it to a view. The view processes the request and returns an HTTP response to the client. Unlike HTTP, the WebSockets protocol allows bi-directional communication, meaning that the server can push data to the client without being prompted by the user.
