Show HN: Effect UI – PoC of a reactive UI framework built with Effect

Hi HN, I'm Mathieu and two days ago I ran into a YouTube video about Effect ("a powerful TypeScript framework that provides a fully-fledged functional effect system with a rich standard library"). This made me so exited that I wanted to build something with it and this is the result!

Effect UI - A reactive UI framework completely build with Effect.

Reactive properties are SubscriptionRefs which make fine-grained reactivity possible (like in SolidJS, no re-renders like in React). Components are just Effects, which makes dependency injection of themes, clients and stores possible by using Contexts.

It is just a proof of concept, but I think it's pretty cool! Let me know what you think or how I can improve it, since I'm definitely not yet an Effect expert.

You can see a basic demo on my Twitter/X profile: https://x.com/m9tdev/status/1938148717158076811
