jotai VS valtio

Daishi Kato, creator of Zustand and Jotai, says there are a few things we need to support RSC serialization:

I've just published jotai-wrapper, a super tiny and simple utility library that makes using jotai even simpler. It comes from the necessity to migrate a project with react-context-slices to jotai. Both libraries share a similar API. While in react-context-slices you have the useSlice hook, in jotai you have the useAtom, useSetAtom, and useAtomValue hooks. In react-context-slices you define either React Context or Redux slices, while in jotai you define atoms. The need for the migration from the first to the second was a high memory usage by react-context-slices when using React Context slices.

Atom-based: splits states into tiny pieces of data called atoms, which can be written to and read from using React hooks. In this group, we have Recoil and Jotai.

jotai Is the signal based state manager I recommended, offering the best developer experience (in my opinion) as it eliminates the necessity to define and update a global store

Jotai 🧙‍♂️

Atomic libs include Recoil, Jotai, and the one I maintain: Zedux. Zedux especially was designed to work well with sockets and RxJS observables and has been getting some traction recently, so of course I recommend checking it out. Feel free to hmu with any questions.

Global State Machine: Jotai (great for any state that needs to be stored globally for your application)

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.

Valtio is like simplified MobX

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).
