Building real time applications with Django
summary
Explains how Channels 2.0 + ASGI let Django handle real‑time protocols (WebSockets) with Daphne as the protocol server, a channel layer for IPC, routers, and stateful consumers that live per‑connection. Builds a mini Google‑Docs style demo: live user counts, per‑document read/edit labels and browser notifications — demoed via video and working. Notes practical details: use Python 3, convert sync/async with sync_to_async, and a pitfall where sending an event with a missing handler silently fails.
