The front end framework for correctness: built on Effect, architected like Elm

I don't know, as far as I can tell the demo on the homepage is bugged? Or maybe I misunderstand how it's supposed to work? If I click reset after 2 seconds and then click add 1 right after it, the reset never fires. What's up with that, that's not what I expected to happen?

The front page example rewritten in Elm, in case you want to compare apples to apples https://ellie-app.com/zqnVHwRJSGpa1

Styling is all gross, sorry.

The project seems super interesting and I've been following since the creator went on an effect podcast I listened to. My only gripe/concern is the fact that the docs are so glaringly AI (likely claude) generated which is something I've come to not expect from technical documentation writing specifically. All in all though, the verbosity tradeoff for explicit design choice here is the right one and I think it does better than elm by remaining in javascript land rather than building a nicer abstraction layer on top that often needs to reach in to do interesting things with the web apis.

Oh wow, a new frontend framework! Has nature finally begun healing or something?

This feels a lot like sagas and redux sagas. Anyone else got that vibe?

How is Effect, for those who have used it? It's good that algebraic effects are becoming more mainstream.

WebContainers have been available in Safari and Firefox for years. Why does it say I need Chrome?

Is this using a different WebContainers?

Just wondering how a matching backend framework for correctness would look like. Ideally something that doesn't repeat the React mess with two routers but fits right in Inertia style.

If only I could have the syntactic beauty and brevity of Svelte 4 with the correctness of this <3

This looks interesting, and I've been keeping an eye on this for a while - but does anyone have experience from actually using this for real?

Is it just me? But every time I use a paradigm of global immutable state, almost always I run into edge cases where practically it falls apart either semantically (mental model explosion) or creates performance issues, whether they stem from architectural problems with the framework itself, or just the way computers operate.

I love both effect and elm, but I cannot swallow yet another Vue/React crap even if it adds effect niceties.

Especially after having used ruby and elixir extensively after years of react/Vue, it feels so backwards (and LLM unfriendly) to split front and backend unless you have gargantuan reactivity needs (you don't).

I wish JS offered just one proper server side focused frontend solution.

As agentic coding matures, this kind of project is the right direction. The mechanics of writing the code become less important. But having a language framework that naturally resists mistakes will become increasingly useful and important.

Similar to how Rust is obviously a better choice today than C++. Who cares if the language is “more difficult” to code in, if the agents are doing the coding. What we need is building blocks that make it harder to author bugs.

Finally someone said it
