Hi everyone!
This week, we welcome 2 new contributors to help ensure the continuity of the newsletter throughout the year, even when Seb takes a break.
Cyril and Matthieu from Theodo Apps (formerly BAM) here 👋, filling in to bring you the latest news from the React and React Native worlds.
It’s a relatively calm week for React, with some ongoing discussions about the Suspense drama in React 19.
But React Native? That’s where the real action is!\
From Expo demoing a way to integrate React DOM components to the exciting launch of React Native WebGPU, there’s plenty to talk about. Plus, we’re diving into new approaches to native module development that are sure to shake things up. And React Native 0.75 is around the corner, we'll cover it next week!
Our partner conf reactjsday (🇮🇹 Verona - 25 October) is celebrating its 10th year by upgrading to 2 tracks (16 talks). Get a 10% discount with code "TWIR". Great speakers have already been announced: Matheus Albuquerque, Aurora Scharff, Dani Coll, and more!

📱 React-Native
React Native WebGPU has just launched, offering a unified API to leverage the GPU for advanced graphics and computation in React Native! By reusing the Web API standard, we will be able to easily integrate existing WebGPU code samples and libraries, such as ThreeJS, directly into React Native.
Beyond just graphics, React Native WebGPU can be used for tasks like matrix computations, making it interesting for on-device machine learning algorithms. It's built using Nitro Modules for smooth Typescript to C++ interoperability. Currently, it's available in technical preview, signaling exciting developments ahead!
The Future of React Native Modules
Exciting times for React Native developers! Marc Rousavy is shaking things up with NitroModules, a new way to write native code 📦 that’s blowing away existing solutions in speed tests. He's encountered some limitations with JSI in VisionCamera. The project is already stable on the C++ side and is already being used in various projects like 🐦 react-native-unistyles and react-native-webgpu, with Swift and Kotlin bindings still in progress.
👀 Meanwhile, a new proposal to push the use of Swift for TurboModules has landed. These changes will ease native modules development by moving away from Objective-C and C++. With these updates, building native modules is about to get a whole lot better!

- 👀 “use dom” - Expo is working on a way to seamlessly integrate React Web components in React Native apps: New experimental Expo feature allows importing React DOM components, communicating with them with props and callbacks! The components are rendered with webviews and not native views, so it will probably be most useful for migrations or secondary features

Looks like there’s a lot happening with React Native these days! Curious about the transition to NitroModules—how does it impact performance compared to previous native module approaches?
