Hi everyone!

The new React site is finally out, and it's safe to say that it kicks ass 🤗 I've put up quite a few related links, and will let you make up your own mind!

There are also some really cool articles. I like the interactive map of React APIs, Remix's approach to breaking changes for v2, or the use of React-Server-Components for translations.

On the React-Native side, the first RC of v0.72 is out. Some long-awaited new features of Metro 0.76 should be available soon, like symlinks support!

⚛️ React

Introducing react.dev

The new React website is finally online! A new article comes with this launch. It's a very big project (both tech and content) that required several years of efforts and many collaborators.

What I like in particular:

• The focus on hooks and functional components
• The guides with many diagrams, illustrations and interactive challenges
• The emphasis of React as a cross-platform solution, not web-only
• API pages well separated in references/usage, current/deprecated, client/server
• The overall consistency of the whole experience

Some changes were also controversial this week, in particular the fact of recommending only a small list of frameworks to start a new React project (Next.js, Remix, Gatsby, Expo) but not recommending many others (Vite, Create-React-App, client-side SPA...).

Also read:

• 📜 New React docs pretend SPAs don't exist anymore
• 📜 How to start a React Project in 2023
• 🧵 Dan Abramov on the shipping the new React.dev website
• 🧵 Dan Abramov on possible futures for CRA - "client-only doesn’t make sense. way too limiting"
• 🧵 Dan Abramov - "petition to retire terms: SPA, MPA, SSR, SSG. they represent the previous generation of tools"
• 🧵 Dan Abramov - "most modern React frameworks don’t require a Node.js server anymore. they just let you add one if you need it."
• 🧵 Dan Abramov - Next.js example - purely client-side SPA (no Node.js server, 100% static bundle)

Map of React API

A spatial and interactive representation of the React APIs, with references to great external articles for each of these APIs. I think it's a great idea and a good opinionated complement to the official documentation.

• 👀 React PR - Suspend commit without blocking render: a feature that will be used internally first, especially on resources (CSS, font, images). When navigating with startTransition, React will be able to wait a bit until the images of the next page are loaded before commiting the transition (details).
• 👀 React PR - Remove layout effect warning on the server: the SSR warning for useLayoutEffect will be removed. Dan Abramov comments on useIsomorphicLayoutEffect.
• 🧵 Tim Neutkens on improving next export: compatible with App Router, Server Components...
• 📜 Future Proofing Your Remix App: Remix explains their strategy for deploying breaking changes on major releases. They plan to introduce "Future flags" that allow you to opt-in for planned breaking changes in advance. If you managed to activate all flags in v1, it should be easy to upgrade to v2.
• 📜 Internationalization In Next.js 13 With React Server Components: Server Components will have a big impact on the way we translate our React apps, especially on performance, code splitting and bundle size. This article introduces the topic well. I give some more extra details in this thread.
• 📜 Hooks You Probably Don't Need: presentation of the lesser known hooks of React, classified by chance to need them (hello useInsertionEffect 😅). I liked the last section presenting a common anti-pattern and how useLayoutEffect prevents it. I think useSyncExternalStore is great for reading browser APIs such as localStorage.
• 📜 Front-Commerce is getting a Remix: after Shopify, it is now Front-Commerce that decides to base itself on Remix. This has many advantages, such as the possibility of using progressive enhancement, an MPA mode, and being less coupled to React.

Build and Run Synthetic Monitoring That Scales

You build it, you own it! It’s a simple mantra that has driven software development for years. But what is the best way to monitor complex React applications?

First: Use Playwright to simulate critical user flows and guarantee that your app works. Second: Be confident that mission-critical APIs are up and running.

Monitoring as code is a new way to define, test, and deploy entire Playwright-based testing and monitoring setup directly from code. Get started with the Checkly CLI by running npm create @checkly/cli.

Learn more about the Checkly CLI here.
