MobX VS valtio

States can also be organized in some central places (aka. stores). You can use Tini Store (very simple, ~50 lines) or other state management solutions such as MobX, TinyX, ...

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

MobX

Mutable-based: leverages proxy to create mutable data sources which can be directly written to or reactively read from. Candidates in this group are MobX and Valtio.

Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/

Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity".

Observables otoh say "fuck it, I'm mutating everything, do what you want with it".

MobX Documentation

There's also others libraries like https://github.com/mobxjs/mobx which aren't specific to RN but can be used in any JS environment.

We took inspiration from the many frameworks we worked with throughout our careers. And maybe surprisingly, Django’s ORM layer impacted our design choices and the API quite a bit. The resulting framework relies on Zod for schemas and validation and Valtio for React integration.

Even simpler than Zustand are state-atom libraries like jotai or recoil, or proxy based ones like valtio. Here's some discussion about the differences.

There is a package developed around this proxy concept called Valtio which is available for JavaScript, React, and so on... feel free to check and star it on Github.

I'm switching from redux-saga to valtio (https://github.com/pmndrs/valtio) for now. It's simple and easy to use, everything's great so far.

I like valtio, works w/ React or just js. Has subscribe, derive, and more.

Jotai and Valtio are both also really good. Recently looked at Nanostore as well and has some similarity to Jotai and Recoil.

Since we want the React component to react to an external change, using a state manager makes this easy. We will use Valtio here by example. For this library, change the esbuild config to --target=es2020 instead to remove some warnings (for example, the Zustand library is ok).
