Air is another library that enables hot reloading in Go applications. To use it, install it on your machine using the command below:

To enable live reloading in Go we will checkout the command tool, Air - Live reload for Go apps.

This is made possible thanks to the Air tool, which now comes with every project you create. The configuration is as follows:

At a recent job, we had slightly different containers for local dev; our backend containers (for a Go app) had Air [1] installed for live reloading, plus Delve [2] running inside the container for VS Code's debugger to connect to. We also had a frontend container for local dev, which didn't get deployed as a container, just as static files.

Air is an automatic reloading tool for Go applications. It keeps an eye on code changes and automatically restarts the application, making development more efficient.

Just to add to the list there is also https://github.com/cosmtrek/air

See one approach here https://github.com/loov/watchrun/blob/master/examples/watchjs-templates/server.go and https://github.com/loov/watchrun/blob/master/examples/watchjs-live/server.go.

For a more complicated setup, you can take a look at https://github.com/loov/watchrun/blob/master/examples/watchjs-templates/server.go, which also auto-reloads the page.

To avoid the loadTemplates call. However, I would use an approach that lets you live-reload the new templates when ever they change -- helps to shorten the iteration time (e.g. one approach https://github.com/loov/watchrun/blob/master/examples/watchjs-templates/server.go).
