4 big news this week:
- React 18 RC2 with official blog post
- The rollout of the new React-Native architecture is accelerating
- The arrival of many APIs in Safari 15.4
On the React side, 2 pretty cool interactive articles.
On the React-Native side, Solito offers a cross-platform abstraction common to React-Navigation and Next.js. Nice comparisons with Flutter.

React 18.0.0-rc.2 has just been released (under npm tag
@rc). The React team published a blog post (+ 🧵 thread) to prepare us for the arrival of this new version. It includes the new concurrent features, which we can adopt incrementally.
They encourage us to test the release-candidate to detect the latest potential bugs, and offer a fairly complete upgrade guide by documenting the main api and behavioral changes. There is also a brief presentation of various new APIs.
Interactive article by Josh Comeau on his file-system structure choices to organize a React app. Strong opinion: he explains in particular why he prefers to group files by type rather than by feature. I don't necessarily agree with everything, but it's still an interesting read and has some good arguments.
Interactive article that presents layout animations with Framer Motion. Very well presented, with many examples. I really liked the example of Tabs with a shared layout animation: the API is quite intuitive, I didn't know it was that easy.
- 📜 How to Use Three.js And React to Render a 3D Model of Your Self: original article that proposes to create your own personal 3D avatar, display it with React-Three-Fiber and make it do some breakdance 😄 I really want to test that.
- 📜 Profiling Next.js apps with Parca: first time I hear about Parca. This seems to be an interesting continuous profiling tool for those who self-host their Node.js apps (with Kubernetes for example) but might also be handy to profile performance problems locally. In this example, the tool detects a performance problem related to the unnecessary use of immutability.

Nicola reminds that the new architecture is coming, and presents the different initiatives to prepare the community:
- The working group
- The migration guide
- The new architecture doc
- The ability to easily enable the new architecture in React-Native 0.68 - coming soon
- Conversion of third-party libs
- The Hermes engine enabled by default
Fernando Rojo regularly pushes innovation in the field of cross-platform (see also Moti and Dripsy). Solito makes it possible to share even more code between web and mobile by offering navigation primitives shared between React-Navigation and Next.js. He's been working on this for a while, it's not the first iteration. It also offers a monorepo example to get you started fast.

Jamon recognizes that Flutter is good on many aspects (DX, CLI, e2e tests, upgrades, performance...). He presents the tradeoffs of both frameworks quite fairly. There is no clear winner. Some important points on which Flutter can hardly compete: web support, sharing code and knowledge, and the ability to hire.
Interesting for a React-Native dev (and also related to the article above) because it highlights the limits of its competitor Flutter to support the web (where React-Native-Web works wellà). Flutter web is not a good choice for content sites, but can remain a good solution for heavier web apps. Note that React-Native-Skia on the web will have similar tradeoffs.

- 🧵 What's next in React Native?
The browser would simply ignore those type annotations and not do any type-checking, so TypeScript (or other type-checkers) remains relevant.
This is interesting in development: we can directly execute TypeScript code without any transformation in the browser. In production, we would continue to bundle the code, because minifying and removing types remains useful (see Ryan Cavanaugh's analogy with minification).
