valtio

Oh.. yeah, the proxy part does look really familiar! :-) Also, their use of promises looks interesting: https://github.com/pmndrs/valtio?tab=readme-ov-file#suspend-... -- I might borrow some ideas from that... :-)

This seems similar to https://github.com/pmndrs/valtio but built directly into the view library, neat!

Looking at how CounterDisplay and CounterControls work at the bottom of the README, the idea behind this is similar to Valtio (direct updates and changes are pushed on update), except with a lot more manual work. Valtio uses proxies and hooks to get the effect of CounterModel, CounterModelProvider, and useCounterModel automatically, without having to write them yourself. For comparison, Valtio has the same kind of "counter" example at the top of their README (first and third code blocks): https://github.com/pmndrs/valtio?tab=readme-ov-file#wrap-you...

The people behind Jotai also made Zustand and Valtio: https://github.com/pmndrs/zustand https://github.com/pmndrs/valtio To me it feels like Jotai has too much manual boilerplate and Valtio has a lot of proxy "magic" that while I do like it I don't feel like it would be a good idea for a team. Zustand sits right in the middle of boilerplate-vs-magic, and is what I chose for a large project we're doing now.

I like valtio, works w/ React or just js. Has subscribe, derive, and more. https://github.com/pmndrs/valtio

Check out valtio if you want to do proxy based state management in react. https://github.com/pmndrs/valtio https://codesandbox.io/s/bitter-night-mm4xes?file=/src/App.j... // a.js import { proxy } from "valtio"; export const a = proxy([]); a.push(1); // App.jsx import { useSnapshot } from "valtio"; import { a } from "./a"; const add = () => a.push(a.length + 1); export default function App() { const snap = useSnapshot(a); return ( <div> <ul> {snap.map((value, index) => ( <li key={index}>{`${index}=>${value}`}</li> ))} </ul> <button onClick={add}>Add element</button> </div> ); }

"UI state knows what its dependencies are automatically and only updates when they change" - you should check out [valtio](https://github.com/pmndrs/valtio).

For another comparison, there's valtio that I learned about from a previous HN discussion: https://github.com/pmndrs/valtio

This is really good feedback. 1. We are going to remove Mobx. It will also reduce the learning curve for our customers. This change won't affect our API and will be fully backward compatible. We are considering Valtio as an alternative [0]. 2. As much as we can help it, we are not going to embed iframes. We'd love to deliver a native, and lean experience. 3. We already provide a network layer library [1] and want to offer more headless components. Can you give us some feedback on what you'd like to see? We are very inspired by Downshift's approach [2].
