fsw is a tool for recursively watching the current working directory and running a command when its contents change.
It's integrated with Git, so it won't rerun the command if an ignored file changes.
You can find static binaries for Linux and macOS on the Github Releases page.
Alternatively, you can use cargo to install the tool.
