PSA: we run a monthly React Native newsletter 📨 What's included? - Key announcements from community - React Native releases - Open Source updates from our team - Practical guides from real projects A clear summary of everything we shared on X that month. The easiest way to catch up!

Always great to see others putting my work to use and sharing feedback! Made my day 🩵

With React Native AI, you can choose the right provider for your use case: - Apple provider → system models built into iOS - MLC provider → run any supported model locally

Run any model locally with React Native AI and AI SDK ⚡️

React Native on Android emulator showing the red box "Unable to load script"? Here's how to fix it 👇

In case you missed it: all React Universe Conf talks are now on YouTube! 📹 22 videos on everything from UI building and React best practices to deep dives into C++ internals of React Native! Brush up on the latest before React Conf! www.youtube.com/watch?v=9vc...

We're over 700 now! Make sure to star it and drop some local AI experience into your app now that iOS 26 is out! x.com/SzymonRybcz...

You know that @chmal.it is cooking 🧑‍🍳 with Rozenite. He's in Prague tomorrow doing a deep dive into React Native DevTools. Ever wondered how they actually work? He reverse-engineered the whole thing and built a plugin framework around it.

Together with Expensify, we're hosting meetup on all things React Native in San Francisco this Thursday! Great opportunity to meet in person and grab your paper copy of Ultimate Guide to React Native! Link to meetup registration in next tweet 🧵

bittersweet news: today is my last day at Bluesky. 💙 i’m very thankful to the team for letting me learn many new things on the job (including React Native). i’m wishing them luck in the improbable — but inevitable — task of making decentralized social media usable and competitive.

Microfrontends for mobile? It always felt like an R&D project—until now. With Re.Pack & Zephyr Cloud, you can actually deploy them today. On React Universe On Air, I spoke with Zack Chapple & @jbroma.dev about what makes this possible & how it changes mobile dev. 🎧 Listen here: hubs.li/Q034sJZt0

So, as far as Bluesky goes, I think I will have to split my video up into even smaller chunks 😂

🎉 Announcing Flows AI: A light-weight library to build agent workflows, on top of Vercel AI SDK. ✅ No unnecessary abstractions. ✅ Use any LLM and provider of your choice. ✅ All patterns from Anthropic article provided out of the box. Read announcement and check it on GitHub ⬇️

A new version of React Native Bottom Tabs 0.8.0 is out! 🎉 Lots of work went into this release: - Complete refactoring of Android view management ♻️ - New Android Page Transitions ✨ - Material You support 🎨 - Other bug fixes 🔧

Double checking in 2025, is there an app to cross-post to Bluesky from X? 🤔

Great breakdown of common agentic flows implemented with Vercel AI SDK!

Love debugging with Cursor: > Ah, now I understand the core issue. The problem is that 😂 Repeat infinitely

A bit too many `react-native start` today

Solving issues around Swift’s modular headers in React Native can be challenging 👀 In this article, I’m going over a few solutions that will help you resolve them! Check it out ⬇️ https://buff.ly/3DZmDkY

After eating 1kg+ apples every day for 2 years, I am officially done... 😂

You know it's a good rewrite coming up! AI space is pretty interesting. Everyone's building AI agents and AI agent frameworks right now. So many different approaches. Everything changes each week. Decided to focus on building some production workflows, hopefully this is the last one 😂

Excited to be back on the React Universe On Air! Memories are back! I love going live, streaming, and being in front of the camera, so hopefully we can get some more content this year!

Totally unrelated, but I in preparation for eye surgery, I moved from contact lenses to glasses after 6 years and WOW, what a difference. Except for the fish eye effect 🤣

Let's gooo! Looking forward. I will be finally able to catch-up with everything thanks to @lukasz.app forcing me to it 🤣

React Native Fast IO is out there on `npm`, latest version `0.2.0`. If you're building something with WebSockets in the next few weeks, I'd love if you could give it a go! [link in thread]

Really excited about this! Nitro Modules are awesome (more on that in my next post), and that's exactly what we need to build more modules with it!

The best build is no build

It's 3am local time and I am reviewing a PR. What did just happen.

Astro is amazing. Everything just works. And it's fast!

Thanks for having me! It was fun! Super excited by Nitro Modules and the IO library! If you're building something that needs exceptionally fast operations on data, you should check it out!

New release is out! If you're following updates on the AI Agent framework I am working on, there are a few you may like!

Surprise coming tomorrow! (and I am not talking about this video, although I am sure it's going to be epic 🤣)

Upgrading React Native in a brownfield app? It’s much more than just bumping versions ⚠️ In the latest blog post, I break down the process step-by-step, sharing tips to avoid common pitfalls and make the upgrade smoother ⬇️ hubs.li/Q02_zS7-0

If this tooling is just half as powerful as the article suggests - this is a revolution in the DX of authoring native modules for React Native hacks.mozilla.org/2024/12/intr...

You know you shipped early when it's 2nd refactor in a week

Bluesky gets it first!

Meet Fabrice AI - functional framework for building AI agents. While building Cali, I needed something stateless that can work on the server, inside CLI, breakdown complex tasks, and be simple. Couldn't find one, so I built one. Give it a try! github.com/callstackinc...

Thinking to do another live stream on Monday to talk about a few new projects and things from @sebastienlorber.com newsletter! Thoughts? 🤔

Dropping something new early next week. Came up with the idea while fixing another library. It's recursion and I am unwinding now 🤣

caption this 🤣 bad takes only

Save the date! Will be doing a release of FastIO live. Hopefully it works LOL

Would appreciate your upvotes on this one 🙏

Save the date for @reactuniverseconf.com 2025: we’re meeting on Sept 2-4 in Wrocław! Blind Bird tickets are available now, so grab yours now at hubs.li/Q02-64M30 and let us know what you’re most excited about: the talks, the networking, or maybe the already famous ice-cream 🙌

Bun ESM/CJS interop is amazing, handles so many edge cases. Makes me want to just compile package with Bun included
