How do I get hot code reloading?

Use Jurigged during development to watch for code changes and reload your app automatically.

Initialize your project (only once)

uv init

Add Jurigged as a development dependency

uv add --dev jurigged

Run your app with hot reload

uv run -m jurigged app.py

reload watches for code changes and reloads the server automatically.
