Here's my thought on 💭 florimondmanca/arel: Lightweight browser hot reload for Python ASGI web apps

arel is a "Lightweight browser hot reload for Python ASGI web apps"

I just implemented this on my thoughts website using fastapi, and it's incredibly fast and lightweight. There just two lines of js that make a web socket connection back to the backend that watches for changes.

When in development mode, this snippet gets injected directly on the page and does a refresh when arel detects a change.








        

const ws = new WebSocket("ws://localhost:5000/hot-reload");
ws.onmessage = () => window.location.reload();
