Browser hot-reloading in FastAPI using arel

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

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.

1. Clone the repo

git clone https://github.com/ashleymavericks/browser-hot-reloading.git

2. Install dependencies

pipenv install

or

pip install -r requirements.txt

1. Set environment variable in your shell instance

export DEBUG=True

1. Verify it using

echo $DEBUG

1. Test this implementation, and further include it in your projects for a better development experience with Python ASGI web frameworks
