OTA sounds simple - ship updates instantly like the web. But at scale, it’s an illusion. @adam_mruk (@Klarna) shares what it really takes to build a reliable OTA system for millions of users.
Composition is React’s most powerful tool, but it’s also one of the most misunderstood. @FernandoTheRojo, Head of Mobile at @vercel, showed how composition is the key React pattern for scaling codebases - from one component to thousands - while staying maintainable.
A React Universe Conf 2025 highlight: a panel marking 10 years of React Native with @tomocchino (@vercel), @cpojer, @ccheever (@expo) & @grabbou (@callstackio). Milestones, key learnings, and most importantly: opportunities and predictions for the future.
From class components ➡️ hooks ➡️ compiler. @anisha_malde (Amazon) mapped out the generations of React, and how each shapes the way developers code, learn & share best practices.
Ottrelite bridges the gap between React Native DevTools and modern observability needs, making it easier than ever to trace, profile, and monitor apps across platforms. @artus9033 and @dominikdolny (@callstackio) bring you the complete picture in one talk.
LLMs aren’t the only AI. In this talk Richard D. Hipp (creator of SQLite) reframes SQL as the AI assistant you already have, and shows why mastering it is key to long-term developer productivity.
There’s one library you need for building AI-powered apps in TypeScript: Vercel’s AI SDK. @mattpocockuk (Author of Total TypeScript) gives a hands-on crash course, showing how to integrate AI into React apps while avoiding vendor lock-in.
Nitro has become the foundation for some of the most powerful React Native libraries today. At React Universe Conf 2025, @mrousavy (@margelo_com) shared Nitro’s journey & what’s next with Nitro Image and VisionCamera.
The Node API is ABI-stable, engine-agnostic & already powering Node.js, Deno & Bun. @Microsoft engineers Vladimir Morozov and Khalef Hosany showed how they integrated Hermes with Node API - unlocking universal native modules & long-term compatibility for React Native.
React has always lived on a single JS thread. But what if it was built for two from the start? At React Universe Conf 2025 @Huxpro, Ziqi Zhen, and Haoyang Wang from ByteDance introduced Lynx, a dual-thread React runtime unlocking new patterns for performance & UI.
Upgrading React Native doesn’t have to be painful anymore. At React Universe Conf 2025 @JorgeWritesCode (@Meta) unveiled a new release process - making React Native more predictable, stable & developer-friendly than ever. And React Native 1.0 is on the horizon 🤞
React Native turned 10 and steps into a new era. @grabbou (@callstackio), @CipolleschiR (@Meta) & @thymikee (@callstackio) explored its past, present, and future - stability, scalability, and a stronger ecosystem - setting the tone for React Universe Conf 2025.
Me yapping about Nitro on stage at @reactuniverse_ 2025 🗣️
🔥 Next.js Weekly #100 → React Universe 2025 VODs (@reactuniverse_) → shadd - better `shadcn add` (@branmcconnell) → Using React's Activity Component (@simeonGriggs) → Dockerize a Next.js App (@ByteGradCom) → Nuqs & URL State Management (@fortysevenfx) (link below)
🎤✨ Had an absolutely incredible time being the MC/Host at React Universe! The energy, the speakers, the community - everything was top tier. Thank you so much @callstackio and especially @mat_kornacki for having me! An amazing time was had @reactuniverse_ 🤩
