A Python-Driven Web App Framework with Django, Channels, and React
summary
A concrete framework shows Django + Channels + React tied by websockets and json‑rpc so Python code serializes UI objects and the front end rehydrates them; a live demo proves the 101 handshake and get_page round trip works and images arrive. Background workers (Celery or subprocesses) push results via a refresh_widget RPC, Redis backs the channel layer, Daphne handles ASGI, and a Python SDK lets data scientists emit components without JavaScript; this is an async publish model, not server-side rendering.
