valtio VS rfcs

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).

Examples from the conversations of that time:

> ...we want closures to capture the values we rendered with, and to keep "seeing" those values forever. That's really important for concurrent mode where a notion of current value doesn't really exist. Hooks design models a component as being in many non-clashing states at the same time, instead of switching the "current" state (which is what classes model well). People don't really need to think about these details, but they're motivating the design a lot. [0]

> In Concurrent Mode, render may run more then one time, and since this in a class is mutable, renders that should be the same may not be. [1]

There are multiple names for this hook. You can find the documentation under the names useEvent or useEffectEvent.

However, in React, function components can return a ReactNode. This type includes number | string | Iterable | undefined and will likely also include Promise( in the future.

I was also hoping that useEvent would eliminate some weird dependency cases, who knows when that will actually happen (https://github.com/reactjs/rfcs/pull/220).

Given a lot of unknowns on SSR and ReactEng working on RSC it feels like the wrong move to use next.js and I should just use normal react. For basic react is create react app the way to go or vite?

As mentioned before, Next.js takes a stance of treating every component as a Server Component by default. If you want to use a Client Component, you'll need to annotate the file with use client; directive at the top of the component file.

Use client is actually a React convention for what it’s worth. https://github.com/reactjs/rfcs/pull/227
