This Week In React 113: React source code, SOLID, Remix, Docusaurus, FP, Remotion, Rapier, Hermes, RN at Airbnb...

Hi everyone!

The newsletter now enterssummer mode: 1 edition out of 2. I hope you enjoy your vacations .

We willlaunch Docusaurus 2.0very soon (2.0-rc.1published). I will send you a special edition for the occasion. It will be the occasion to present you better this project I work on since 2+ years with Facebook. Docusaurus 2.0 is not the most famous React framework, but it remainsvery useddespite being in beta: twice as much as Remix or Redwood, and is progressively catching up with Gatsby. I hope I can count on you for theProductHunt launch.

This week, I want to highlighttRPCto make remote calls (client/server or even server/server). Typical end-to-end solution, agile, and much easier to use than GraphQL. There is no particular event related to the lib, except a significant gain in popularity thanks to Theo and hiscreate-t3-appframework.

See you soon for the Docusaurus launch .

React

Reading Source Code: React

Alex reads the React source code and comments on several parts, taking as an entry point the mount of a React application. Interesting details about the use of prototypes, JSX, and the interaction of the (agnostic) reconciler with the DOM renderer.

Can We All Just Admit React Hooks Were a Bad Idea?

Amy argues that React hooks do not respect SOLID architecture principles. I don't really agree, but recognize that most of the examples found on the internet are simplified and don't necessarily highlight a good architecture.

Applying SOLID principles inReact

Almost a direct answer to the above article, even if the application of SOLID is more widely covered here (components + hooks). Note: don't hesitate to use the React context for dependency injection.

Extras:

• Avoid anonymous components with displayName: sometimes React can't infer a good name for your components, which complicates the use of devtools (Context, memo, forwardRef, HOC)
• Why Remix is not a React framework but a full stack web framework: a well-written overview of the differences between Remix and other frameworks. Remix is full-stack and framework-agnostic.
• Functional programming is finally going mainstream: GitHub highlights the popularization of functional programming, in part thanks to React, Redux and hooks. I personally switched career from Scala to React after reading David Nolen's famous post. Didn't even like JS before 2014
• Why Docusaurus is a powerful documentation framework: 1Password explains why Docusaurus is a good solution for their developer documentation portal. Touch various advanced topics, including site customizations, remark plugins to extend MDX/Markdown...
• Store data in a cookie with sessions and Remix: creation of a visit counter cookie
• Remix Deferred: new API under development that gives fine control over data loading tradeoffs on initial page load. Optimize for Time-to-first-byte or Cumulative Layout Shift.
• Next.js accessibility doc improvements
• New Preact VDOM state model
• Remix + React 18 startTransition + time-sliced hydration: Ryan Florence sharing a controversial tip. Starts interesting discussions about hydration (Ryan Carniato,Andrew Clark...)
• pmndrs/react-three-rapier: integrates react-three-fiber with Rapier (physics engine)
• Remotion 3.1: many new features! Gifs, Tailwind CSS, springs with duration, OffthreadVideo...
• Remix 1.6.5: loader + useLoaderData TypeScript inference
• Framer Motion 6.5: scroll animations
• Zustand 4.0.0-rc.2: ready for production

React-Native

Hermes as the Default

The JS Hermes engine is an alternative to JSC/V8. It can help your app to start faster via a pre-compilation in bytecode. With React-Native 0.70 (now inrelease candidate), Hermes is enabled by default. Michael shares various benchmarks from the open-source app Mattermost. The Hermes distribution mode has changed to avoid ABI incompatibility issues. Missing Intl APIs have been added on iOS. Upcoming support for BigInt and WeakRef.
