This Week In React 143
RSC Quiz, useFormStatus, Next.js Website, Panda CSS, useLayoutEffect, Million.js, Immer, Super Apps, React-Three-Fiber, Vite...
Hi everyone!
We have a lot of great React articles this week, but also some nice releases. I liked the breakdown of the animations on the new Next.js website, and the discovery of the new Panda CSS library.
We feel that React is becoming more and more a framework with the Server Components. A new experimental hook useFormStatus
is coming 👀.
Callstack offers us a nice resource on Super Apps in React-Native.
There was a big wave of layoffs at Meta 😓.
FYI this newsletter has a Discord chat. It used to be French-only, but I reorganized it to welcome all of you now, so please join us and let's have a chat!

⚛️ React
You may have noticed the new Nextjs.org landing page? Rauno works at Vercel and deconstructs the UI subtleties of this page. Personally I love their gradient tracing technique! Interesting React implementation and great result.
Panda CSS – CSS-in-JS without Runtime Overhead
Panda CSS is a new zero-runtime CSS-in-JS library under development for the future of Chakra UI. The Panda doc is not yet available, but this article gives a first pragmatic overview in a Next.js context.
👥 New wave of layoffs at Meta that also affects open-source tech profiles of our community, including Mengdi Chen (React DevTools), Robert Balicky (Relay), Matt Carroll (DevRel React, looking for a new job) and Sean Keegan (DevRel React, looking for a new job). Feel free to reach out to those who are looking for a new opportunity.
👀 React PR - experimental_useFormStatus: a new hook
useFormState()
could arrive in React, whose signature is inspired by RemixuseNavigation()
.👀 React.dev translation update: the translation repositories of the new doc are up to date. It is possible to start translating the new document.
🧵 Dan Abramov's RSC Quiz: a very interesting thread that could help you to have a better intuition on how Server Components work.
🧵 Dan Abramov on the origins / inspirations of React Server Components (PHP/Hack/XHP)
🧵 useLayoutEffect + queueMicrotask: my tip got more interest than I thought 😄
🐦 Dan Abramov on using Preact Signals: this patches React, which can not guarantee its proper functioning if you decide to use it.
📜 Why You Don't Need Signals in React: Daishi explained that signals are characterized by 2 elements: responsiveness, and diffing bypassing. He proposes to use Jotai for reactivity, and not to try to bypass diffing.
📜 Creative ways of using useReducer: highlights 4 original ways to use
useReducer
: toggle, increment, state formatting and state merge.📜 Where to host your Remix app in 2023: good analysis with a comparative matrix to choose your host.
📜 Securing your Next.js 13 application: shows how to secure its Next.js app with headers, and proposes a detailed implementation for CSRF.
📜 Can Rust Beat Javascript in 2023?: Web frameworks based on Rust and WebAssembly have progressed well in benchmarks. This also shows that they have a fairly similar model to React.
📜 Say no to "flickering" UI: useLayoutEffect, painting and browsers story: implements a responsive navigation menu, and explains how a synchronous
useLayoutEffect
can fix a visual glitch of the 1st rendering. For SSR, it's not that simple!📜 Display a view counter on your blog with React Server Components: replace SWR with RSC to display a view counter. Adding a Suspense around the counter allows not to block the rendering.
📜 How we built the Storybook Day 3D animation: explanations on how to create a 3D scene with React-Three-Fiber.
📜 The Evolution of React Rendering Architectures & Web Performance
📦 Vite 4.3: big performance improvements on a benchmark with 1000 React components.
📦 Redux Toolkit v2.0.0 alpha.5: new
combineSlices
API to lazy-load reducers.📦 T3 Env: new solution to parse environment variables with Zod, with Next.js integration.
📦 React-Three-Offscreen: allows React-Three-Fiber 3D rendering in a web worker via an OffscreenCanvas, to avoid blocking the main thread.
📦 Million.js 2.3.0: Next.js support and optimizer Forgetti integration. A new package Hundred.js to understand how the block-based virtual DOM works.
📦 Immer 10.0: faster, smaller.
📦 Micro Frontends Next Generation - A React Server Components Playground
🎥 Next.js Image Component Just Got Way Better: show the advantages of using Cloudinary in a Next.js app. I take the opportunity to thank James for the newsletter shoutout 🤗.

📱 React-Native
Callstack published a great resource on Super Apps, which allow to assemble several mini apps under a single mobile interface. They describe the business and organizational benefits as well as the possible technical solutions, and highlight their preferred solution: Re.Pack and Module Federation. There is also a repo Super App Showcase with an example Super App to study.
Super Apps are popular in Asia (WeChat, MoMo...) but are gaining momentum. My intuition tells me that the PlayStation 5 UI could be a React-Native Super App, to be confirmed!
👤 Mark Lawlor (NativeWind) joins Expo: good news for the community, one more dev to work on the web/cross-platform support.
👀 Bluesky - Universal Expo app: we have Twitter and its new competitor Bluesky both using React-Native-Web.
💬 RFC: Support Expo Config Plugins in React Native apps: proposes to upstream Expo Config Plugins directly into React-Native core for various DX reasons, including making upgrades easier. Proposal challenged by Brent Vatne and the community as it is not that hard to add Config Plugin / Prebuild support to an existing React-Native project.
