There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it.
A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately.

I was on the fence about RSC.
I could see the new abilities it unlocked. But I was wary of the added complexity, and I felt like it wasn’t solving the problems that originally brought me to React.
Seeing Parcel’s low level RSC APIs (and now @vitejs/plugin-rsc) changed my mind.

Happy to announce Parcel v2.14, now with support for React Server Components! 🥳
RSCs can be integrated into client-rendered apps, server rendered, or statically rendered at build time.
Also: rust MDX compiler, create-parcel CLI, new error overlay, and native import maps.
ALT Screenshot of code sample: $ parcel server.tsx // server.tsx import express from 'express'; import {renderRequest} from '@parcel/rsc/node'; import {Page} from './Page'; const app = express(); app.get('/', async (req, res) => { await renderRequest(req, res, <Page />); }); app.listen(3000); // Page.tsx "use server-entry"; export function Page() { return ( <html> <body> <h1>Hello world!</h1> <Client /> </body> </html> ); }

“takes a while to get something in the app and approved by the app store”
Apps should iterate just as fast as websites. Use Expo to share React code and push out changes to all users instantly with OTA updates.

react.dev is designed for folks who are new to React or are learning basic React concepts. While we'd love to have docs for more advanced users of React (e.g. libraries, frameworks, build tools, etc.) we don't have the resources to make that happen today

We think there is a place to recommend build tools and that is why we created the "Build a React app from Scratch" page. We wanted to have a place to recommend build tools without leading new React users down a path we can't, in good faith, recommend react.dev/learn/build-a-reac…

This isn't perfect and most of the folks reading this post aren't the primary audience for this page (or react.dev) because they know the tradeoffs already and can make their own, informed decision
