How do you use OTA updates? As a fire extinguisher for critical bugs, or as a decentralized CI/CD tool for the entire stack? In this interview, Adam Mruk (Klarna) explains why they use a centralized OTA approach for hotfixes, shipping only diffs. Zackary Chapple (Zephyr Cloud) counters with the case for Module Federation, pushing deployment responsibility to teams and managing dependencies across web, BFF, and native. They debate the trade-offs between safety, speed, and platform complexity ▶️ https://lnkd.in/dz2UAq7e

We played the newlyweds game with 𝝠 Cedric van Putten (Expo), Tommy Nguyen (Microsoft), and Delphine Bugner (MistralAI) to see how aligned they are on React Native tooling. The results? Total agreement that TypeScript is a must and class components are dead. But the best part was the build horror stories, including one that was solved by unplugging an external monitor that was blocking the WiFi signal! Full game 📺 https://lnkd.in/dETzC5qX

The biggest performance problem in React is just rendering too much. Would you agree? In this interview, Jay Meistrich(CTO at Bravely, creator of Legend State) argues that state, not lists, is the primary performance bottleneck. He explains how React's top-down reconciliation model is not performant by default. His solution: Legend State uses a signaling system where components subscribe only to the granular state they need, resulting in tiny renders and bypassing the cascade.

What if you could migrate web apps to native without rewriting all your CSS? In this interview, Xuan Huang (Architect at ByteDance) introduces Lynx, am open-source platform inspired by React Native. He explains two key innovations: ➡️ Native CSS support to ease web migration. ➡️ A two-thread (BTS/MTS) architecture to solve hybrid native/RN UI synchronization issues. Learn how Lynx is framework-agnostic (with Vue/Svelte support) and powers Bytedance's "mini app" ecosystem ▶️ https://lnkd.in/dtS_Y7wz

How does a complex technology standard like Node-API get built in the open? It's a community effort. In this interview, Khalef Hosany (Microsoft) explains how the project grew from an internal prototype for React Native on Windows to a public-facing initiative. Kræn Hansen (MongoDB) discusses how "nerd sniping" and a desire to solve shared problems fuel contributions. Both agree: the project is at a critical stage and needs developer feedback to set priorities. Learn how you can contribute ▶️ https://lnkd.in/d6Tfp4uy

React Native is 10 years old, but stability is the theme of this year. Why now? As the core stabilizes, the ecosystem is expanding to TVs, AR, and web. This creates a new challenge for library maintainers. In this interview, Chris Traganos Trag and Steven Johnsen Moyes (Amazon Developer) discuss this tension and why the brownfield approach is the key to enterprise adoption. Watch the full discussion ▶️ https://lnkd.in/d9BAZr4X

React Native developers who love Tailwind syntax now have a powerful new option: Uniwind. In this interview, Jacek Pudysz (Codemask.com) discusses why he built this new, blazing-fast library. He explains how Uniwind is built on the exact same JSI-powered core as the popular Unistyles, and makes it clear that Unistyles isn't going anywhere, it will continue to be a main, supported project ▶️ https://lnkd.in/d-rJxWG6

Can you teach an AI to write more maintainable code? Fernando Rojo (Vercel) discusses how he's building the new native v0 app and using AI as a key creative tool, replacing static design tools for rapid prototyping. He shares his workflow for improving AI output by feeding it examples of good patterns, like composition, to ensure the generated code is readable and maintainable ▶️ https://lnkd.in/d394nyPj

What is the true role of Developer Advocacy? @Anisha Malde (@Amazon Developer) demystifies her job, explaining it as being the developer's best friend. She shares how advocates act as "Developer Zero", the first users of new APIs, to test, fix, and improve the developer experience before it's released. It's a critical role of translating complex engineering into a digestible, delightful product ▶️ https://lnkd.in/dnhaS_T8

How do you balance the power of LLMs with the real-world risks of sending private data to the cloud? @Matt Pocock discusses his journey from AI skeptic to pragmatic educator. @Szymon Rybczak (@Callstack) introduces the solution: react-native-ai, an open-source library that runs LLMs directly on-device. They explore the importance of privacy, offline functionality, and using the right tool for the job. ▶️ https://lnkd.in/dPYA-WYk
