embed.FS is really cool. If you wanna see what it looks like, check out how I build ntfy [0]. It ships with the docs (built from mkdocs, see [1]) and the React web app [2] all in a single binary.
Here are the embed statements [3]. One thing to note is that embed.FS does not send 304 Not Modified status back, which is why I made a CachingEmbedFS [4].
