I created this some years ago: https://github.com/philippgille/serve https://github.com/philippgille/serve It's written in Go, has zero third party dependencies, supports optional basic auth, and optional TLS cert generation (self signed) for local HTTPS. Not updated in a while though. And if you drop the requirement for minimalism I'd second the recommendation for Caddy instead.
