This would be a very useful feature to have baked into Echo with some sort of development flag, or as mentioned when Debug is enabled. There was a third-party echo-livereload package but there was a breaking change in Echo that made it incompatible. Most generic implementations require proxying requests which isn't ideal.

I think this is a good feature to have natively implemented rather than just be a recipe. It's a small quality of life improvement that makes a big difference when making a lot of small changes to an application.

I've used air with the default .air.conf without any issues so far.

Is there any update on this? Restarting the server every time is tedious, atleast for local development
