This is very cool. I'm working on a side project right now with a go back end and alpine front end. One of the things I've had to overcome is handling cookies and CORS since not everything is served from localhost.

I ended up packaging my frontend in an nginx container and using that same nginx container as a proxy for the backend but the whole time I thought maybe this small project would be easier if everything was served by go.

Will definitely keep an eye on this for future stuff.
