This Week In React #134: Gatsby ️ Netlify, React DOM for Native, XState, Flashlight, re-renders, Custom Hooks...

Hi everyone!

Gatsby has just been acquired by Netlify 🤯!

There is also a very interesting RFC to read if you are passionate about cross-platform in React-Native.

Otherwise, it's a pretty quiet week. That's good timing, because I don't have much time 😄. I'm finishing up some preparations for next week's email which will be a bit different.

Netlify Acquires Gatsby Inc. to Accelerate Adoption of Composable Web Architectures

This is the big news of the week. Gatsby Inc. bought by Netlify. The framework is now under the Netlify umbrella alongside Eleventy and SolidJS and will continue to evolve. The cloud features (including the Valhalla Content Hub) will be integrated into Netlify's offerings. The new slogan is "composable architecture". Gatsby is not the most popular React framework right now, but I think this acquisition makes sense, especially for the content hub and all the CMS integrations they have been working on. The Gatsby Cloud offering is harder to adopt than an optional paid features on Netlify, and that's even more true for sites that don't use Gatsby as a framework.

Making state machines global in React

Presentation of the new createActorContext API appearing in XState 3.1. It allows to facilitate the creation of global XState state machines, associated to a React context. It is possible to use a selector system, or to provide a custom state machine to the provider (this looks convenient to customize a machine from parent props).

📜 React recursively re-renders child components, but there is a nuance: nice visual article that illustrates how component splitting and state colocation can avoid unnecessary re-rendering.
📜 Custom React Hooks and When to Use Them: sometimes you have to create custom hooks, even if they are not intended to be reused. But be careful: unnecessary abstractions also have a cost.
📜 TypeScript Utility Types You Need To Know: presents in particular Awaited and ReturnType, but also Readonly in a React context.
📜 React JS Best Practices From The New Docs: Interesting reading for those who want to have an overview of the content of the new doc. I don't agree with all the comments, in particular don't miss the underrated useSyncExternalStore 😄.

React DOM for Native (reduce API fragmentation)

The RFC by Nicolas Gallagher (Meta / React-Native-Web) has just been updated. The goal is to align React-Native APIs as much as possible with Web APIs, including DOM elements like div, span and even select! The "learn once, run everywhere" could gradually turn into "write once, run everywhere". The community is quite divided. We'll have to sleep on it a bit know if it's a good idea 😄, and considering the size of this ambitious project, it's clearly not for tomorrow!

📜 How to swap between React Native Storybook and your app: useful technique for those who have a React-Native Storybook. Personally I like to have a menu bar in dev with buttons to open/close the Storybook, change the API environment or other... It saves a lot of time in the long run to create your own DX.
