You don’t. Django is fundamentally designed around the “request / response” cycle.

Providing asynchronous communications to the browser is outside the realm of Django itself. That’s why the Django Channels project exists.

You can run an EngineIO server in parallel to your Django environment, allowing it to handle your websocket connections, but I’m not sure what the benefits would be over Channels. (Likewise, you could run ws (node.js) or any other websocket server to do the same.)
