I hesitatingly post this. There’s not much to “showcase”, honestly, and the number of people who will actually value this is probably quite low. My real interests for zig lie elsewhere, but this project is motivated from my Python webserver projects, and my age-old trusty use of dominate, combined with interest in practicing the likes of @matklad‘s NewType and some other idioms, and interest in “serving” most/all HTML over websockets for client rendering. I may someday rewrite some of my many Python projects to try using this scheme “for real”, but if the efficiency advantages were actually attractive (I haven’t profiled anything), the results would surely be overkill for my little lightweight projects.
Anyway, be gentle with this beginner, but feel free to poke around and offer advice, unless it’s just, “who would ever use something like this?” - that, I get. 
(This is also my first use of Codeberg, migrating over from github days)
P.S. - yes, I know there’s no such thing as an “HTML server”; there’s more to that moniker than I care to babble about now. And NO, this is not an HTTP server.
