Browser hot-reloading in FastAPI using arel

Implementaion of lightweight browser hot-reloading for Python ASGI web apps frameworks like FastAPI using arel

What is arel?

arel can be used to implement development-only hot-reload for non-Python files that are not read from disk on each request. This may include HTML templates, GraphQL schemas, cached rendered Markdown content, etc.

How does arel work?

arel watches changes over a set of files. When a file changes, arel notifies the browser (using WebSocket), and an injected client script triggers a page reload. You can register your own reload hooks for any extra server-side operations, such as reloading cached content or re-initializing other server-side resources.
