macchiato-core VS garden

If you're willing to base "cross-platform" on Node [1], then you can loosely achieve this with some choice of ClojureScript on the front end, and macchiato (which sits on Express) on the back.

Thanks for the vanilla-extract recommendation, I'll be using this!

In my case, tailwind was useful for providing a handy set of vocabularies for simple and common stylings. But once customizations start to pile on, we're back into SCSS. Using 2 systems at once meant additionally gluing them with the postcss toolchain, so effectively we have 3 preprocessors running for every style refresh.

Looking in at TypeScript from the clojurescript ecosystem though, I'm still yet to see an equal to https://github.com/noprompt/garden or https://github.com/Jarzka/stylefy: single language, excellent composability, compile-time anonymous class names, inline styles... almost like they solved CSS (except for typing)

I spent some time doing this ~3 years ago, so I don't know about now, but to my knowledge it was the only language where you could really use one language for everything: no HTML (via hiccup), no CSS (via garden), clojure/clojurescript everywhere, and no shell (via babashka).
