Django Channels & ASGI: Real-Time WebSockets

1. Deep Architecture

ASGI handles long-lived client connections that standard synchronous WSGI cannot. Under Django Channels, Uvicorn or Daphne routes WebSocket connections to channel layers, keeping socket state in memory using Redis Pub/Sub backends.

2. The Feynman Gatekeeper

[KNOWLEDGE CHECK] Explain why a standard Django view cannot maintain an open connection with a browser, and how ASGI solves this.

3. The Code

# routing.py
from django.urls import path
from channels.routing import ProtocolTypeRouter, URLRouter
from sanjaya_core.consumers import EvaluationConsumer

application = ProtocolTypeRouter({
    "websocket": URLRouter([
        path("ws/eval//", EvaluationConsumer.as_asgi()),
    ]),
})
