rfcs VS rfcs

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.

-https://www.patterns.dev/ -https://github.com/reactjs/rfcs/blob/main/text/0188-server-components.md -https://dev.to/this-is-learning/qwik-the-post-modern-framework-3c5o -https://dev.to/this-is-learning/astro-framework-169m -https://developers.google.com/web/updates/2019/02/rendering-on-the-web -https://web.dev/vitals/

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

You could avoid shipping down the JSX templates but only by promising to never render a comment on the client. That's basically the approach taken by this React Server Components proposal: https://github.com/josephsavona/rfcs/blob/server-components/...

Rails has experimented with this sort of thing in the past; it requires some deep integration with the HTTP server so that clients can request updates to specific chunks of the UI rather than just URLs.

a nice summary can be found here: https://github.com/josephsavona/rfcs/blob/server-components/text/0000-server-components.md

Server Components allow developers to build apps that span the server and client, combining the rich interactivity of client-side apps with the improved performance of traditional server rendering. RSC Server components have no impact on the app’s bundle’s size. RSCs can be used to fetch data from API and can’t handle state management.

With that in mind, if you’re the type of person that likes to experiment with the latest and greatest, React Server Components is well worth trying. The Server Components intro video is excellent, the React team’s RFC is a well-written guide that details how everything works. There’s also an open pull request where you can submit your own feedback on the feature.

> At a high level, React Server Components are Components that can be rendered on the server and on the client.

This is blatantly wrong. The RFC (and Dan Abramov’s video) make it clear that server components can only be run on the server, and client components can only be run on the client - only shared components run in both environments: https://github.com/josephsavona/rfcs/blob/server-components/...

There were several motivating factors behind the creation of React Server Components (the RFC lists them all), but I wanted to focus on two of the problems that I see in my work that React Server Components solves: large bundle size and waterfalls in fetching data from the server.

We could mention many other benefits, like automatic code splitting, UX improvements, etc., but I recommend you read the RFC for an in-depth explanation. For now, let’s see an example, so we can better understand how these components work.
