I maintain a Rust-based CLI HTTP server that embeds Nushell. It’s a handy little Swiss-army knife that’s replaced Nginx and Caddy for my personal projects.
You can serve a folder of static assets like this:
http-nu :3021 '{|req| .static "www" $req.path}'
I was looking to try something like this (without the nushell...), but I find that I always have caddy installed anyway, and for the really local cases I use php -S.
I'm curious, what do you think is missing from Caddy that has you looking for something new?
