Better React Native starts like a good meal kit: clear recipe, quality ingredients, zero guesswork. We trained 15 HelloFresh engineers in 8 weeks, resulting in faster delivery and a reusable onboarding playbook. Dig into the case study 👉 clstk.com/4kRmQX5

For a long time I thought the partial adoption/brownfield approach was an amazing way to use React Native. But it always scared me how hard could it be to get started. And that's the exact reason why we created yet another book @callstack.com. Get a copy free of charge here: clstk.com/4kU87L3

Ever wondered why React’s "Fiber" is called that? Turns out it’s more than a name. It’s rooted in coroutines, user-space threads, and task scheduling. This deep dive explains how React, game engines, and modern runtimes squeeze performance using fiber-based systems. clstk.com/44N5FRQ

Step-by-step, code-first, and written by the devs who built the tooling. Our new ebook is your guide to integrating React Native into native apps in a modular, gradual, and production-ready way Includes: ✅ Packaging configs ✅ XCFrameworks & AARs ✅ Brownfield best practices Read it now 👇

Spinners are out, and shimmers are in ✨ We just released a new library for React Native that makes your loading states beautiful, fast, and modern. It’s called `react-native-fast-shimmer` and @q1w1n.bsky.social wrote an article about it clstk.com/44Qs8gV

Want to write your first cross-ecosystem native module? @shirakaba.bsky.social shares how to use Node-API to create a native module that runs not only on Node.js, but React Native, too clstk.com/3INHNVm

Big news: the React Native DevTools framework is dropping by the end of this month 🔥 The name? It's locked in and I'm so excited about it. It kicks off a whole family of tools designed to push React Native even further… but I'm not allowed to say anything else at this point 🙊

What if your CI only built what mattered? In our latest React Universe On Air, Jordan Powell explains how Nx helps teams build monorepos that don’t feel monolithic. Watch here → clstk.com/44yRKib

Live dev session - what should we play with today? No new ThisWeekInReact yet (we’re refreshing our inbox hourly), and I just did the NODE-API stream yesterday. I forgot to show off BISON last week. If you wanna see what that is, join us live! Streaming today at 5 PM CET clstk.com/40joutb

We go live at 5PM CEST ⏰ Node-API in React Native: high-performance native modules. Watch it here 👉 clstk.com/3U7qfG8

React Native gets Apple Intelligence 🎉 We just dropped preview support for on-device Foundation Models: • Text gen & treaming • Structured output • Vercel SDK-ready Find out more in @grabbou.com's blog post ➡️ clstk.com/4nSRzG4

Monorepos can be intimidating. Thousands of files, tangled dependencies, CI times that never end… But what if they could feel like a piece of cake? In our next episode, Jordan Powell (Nx) shows how smart tooling makes monorepos scalable and actually pleasant to work in 👉 youtu.be/9OqzGMWHZTA

We’re going live on July 15 to show how Node-API powers native modules in React Native, without platform-specific hacks. Join @lukasz.app, @kraenhansen.dk, and MariuszPasiński at 5PM CEST 👉 clstk.com/3Uamb80

What’s happening in React & React Native? We’re going live to explore the ecosystem—tools, news, code, and maybe some bugs 👀

Performance isn't magic—it’s patterns. @kwasniew.ski walks through practical React Native optimizations you can use today. Think React Compiler, FPS tips, Hermes configs Watch the full talk 🎥 BS clstk.com/4mJuxR5

When your LLM says there’s someone home… but you live alone. Welcome to the world where Model Context Protocol meets real-time IoT: Claude + Node + actual home sensors. Blog post by @q1w1n.bsky.social ➡️ clstk.com/4kx9S1i

Episode 2 of React Native Optimization in Practice is here 🎬 This time, @thymikee.bsky.social‬ covers another common pitfall: using web polyfills in React Native when you don’t need them. The fix? Use dedicated SDKs built for mobile. Here's why 👇 youtu.be/_Yo1kHz7h_I

Tracking everything doesn’t mean tracking what matters. Expensify’s Tim Golen explains why most performance metrics are noise—and how they built KPIs that actually reflect UX (spoiler alert: StatsD + Grafana + weekly impact reports) Watch it here 🎥 clstk.com/4ktb4mq

You don’t need to wrap your app around React Native. We showed how to drop it in as a framework, just like any native library. Webinar recording featuring a live demo and updated React Native Brownfield library is now up 👉 clstk.com/3Fvu4RX

How do you run a large language model locally in React Native? We’ll show you MLC and `react-native-ai` in action. See how it works, where it started, and what’s coming. 🕕 6PM CET 📺 Link  clstk.com/3HiIRjn
