Air — Go Hot Reload

Air watches Go source files and rebuilds/restarts your app on changes. Essential for web server development where you want sub-second feedback.

Install

go install github.com/air-verse/air@latest

Basic usage

Run air in your project root. With no config, it watches .go files, rebuilds, and restarts. For anything non-trivial, use a .air.toml.
