If you are wondering why the binaries are so large, it's because they are packaged-up node.js binaries. I tried to learn a compile-to-native language to rewrite this in so you won't have to download such bloated binaries but didn't get far. I learned Swift and still have a WIP branch up for it[2]. I gave up after learning that there's no well maintained windows http server for swift.
I'm currently on my journey to learn Rust. So maybe one day when I do, you'll see the binary sizes drop.
