⚛️ React
Segun Adebayo (creator of Chakra UI) unveils his long-awaited CSS-in-JS library (trailer). It offers very great DX, is based on modern CSS features (cascade layers), is performant (static analysis at build time, no runtime, atomic CSS)... In short, it ticks a lot of boxes and is generating a lot of interest. It integrates particularly well with React (JSX style props, React Server Components compatible, etc.), but can also be used with other frameworks.
This is a library to keep a close eye on and one that could well compete with Tailwind: it integrates better with the target frameworks and doesn't force you to use a lengthy className.

📱 React-Native
React Native 0.72 - Symlink Support, Better Errors, and more
After several Golden RCs, the latest version of React-Native has finally been released and will shortly be used in the Expo 49 SDK. There are quite a few improvements mentioned (DX, Hermes, performance...) and some breaking changes. I particularly like these 2 new features in the Metro bundler:
- Symlinks (beta): long-awaited feature to simplify monorepo and pnpm support
- Package Exports (beta): better encapsulation of libs, compatibility with the rest of the frontend ecosystem and ability to expose a specific React-Native entry point.
