✨Announcing the React Native Porto meetup @reactnativeOPO 🇵🇹✨ 🌞 The RN community comes to PT for the first time! Let's enjoy some sun and talk all things React Native ⚛️ 🗓️ Precise date still to be confirmed, but we should be meeting in May, just before conference season

@thymikee @SpotifyEng Unfortunately the mobile apps are the only usable apps for Spotify All web or desktop versions are unreliable to the point you cant change the music

pls fix accessibility on macOS @SpotifyEng 😭

@wesbos the whole chat experience on @X

what is a bug where you would join the company, fix it and immediately quit?

Its funny how Rozenite already feels like an essential piece of the RN ecosystem, and this new release pushes it even more 🔥 One of the cool new features is a File System plugin I worked on, to allow you to preview files in the hard disk, such as an image cache!

The new File System plugin lets you inspect files accessible to your app directly in React Native DevTools. It also includes agentic capabilities, allowing agents to use file access as part of debugging and investigation workflows. Kudos to @thiagobrez for the work on this 👏

Presenting native screens from React Native in a brownfield app sounds simple… until you actually try to implement it 😵‍💫 That’s why we built @callstack/brownfield-navigation - a clean, typed way to present native screens from RN. Built for better DX across RN + native teams 🚀

@itsashis4u @satya164 Yep, it's also used by hot-updater

@satya164 Awesome! Will try it out

expo/fingerprint doesn't get enough praise. such a useful library

Which AI coding model actually writes good React Native code? We couldn't prove it either, so we built a benchmark. React Native Evals: 43 real-world tasks across animations, async state, and navigation. Read more on our blog ⬇️

Introducing: React Native Brownfield Migration skill 🔧 It's never been easier to migrate native apps to React Native and Expo. Give it to your agents skills.sh/callstackincub…

we're working on a new devtool company the goal is to provide reliable feedback to humans and agents whether new feature/bugfix/refactor works correctly. it's time to remove testing bottleneck. DMs are open, feel free to reach out for early access!

agents are getting more and more capable every day. soon most of software development will look like: > make me feature XYZ > *agent works on this in the cloud*.. here is a pr then the biggest bottleneck will be testing. I'm working on a startup to solve this. DM if you are interested.

@SzymonRybczak @satya164 sneak peek

can't wait to share on what we're working on. new devtool, launching soon.

Introducing: React Native Brownfield v3 with Expo Config Plugin ⭐️ Add Expo to your native iOS & Android apps in minutes using our battle-tested approach @callstackio

Brownfield so easy these days 👀

@o_kwasniewski minisim is goated 🐐

MiniSim.app reviews on gumroad ⭐ Seriously grateful for every single one 🙏 I’m setting MiniSim to $2.99 on Gumroad to support further development. It will be free on GitHub - forever. If MiniSim saves you time, supporting on Gumroad means a lot. 🙏

@birch_js Seems like it's a pattern for East Asia. We noticed the same for China

The more I speak with React Native and Flutter devs in Japan, the more I feel we’re like an endangered species. It’s all pure iOS and Android dev out here.

@adnansahinovich We'll let you know soon to add the date for @reactnativeOPO #2 edition 👀

I built a world map of every major React Native event happening in 2026 From Kraków to Tokyo. From NYC to Portland. If you're building with React Native, this is your global calendar. Explore the map: nativeweekly.com/events

Back in OPO.js with @Danny_H_W when we were planning to start our own @reactnativeOPO A few months later it was real, and it's already past, crazy Stay tuned for the next one 🔜

@Danny_H_W @oponetwork I bet you were showing something awesome

@oponetwork @thiagobrez spotted you

Not doomscrolling. Saving the date. 📅📱 #OPOnetwork things... Btw: Feb 12th 🤫

@Danny_H_W Good take

Sounds strange but 10.2.2 is the first version of react native storybook that was published with CI. The last 5 years I've always just run the publish on my local machine using lerna. It just never seemed worth it to spend time setting up CI instead of working on something else. This weekend though I've moved from yarn to pnpm and lerna to changesets. Maybe setting up turborepo next. Honestly this still kinda feels like busy work... it was working fine. However I can't deny I like tweaking the system. Just have to be careful not to fall into the trap of spending all my time configuring instead of coding. This is the kind of things LLMS are really great at doing at least so its mostly just directing. Heres hoping it stays working and I can not touch it for another 5 years 😄.

Heres my talk about React Native @storybookjs from our first @reactnativeOPO meetup. I talk about how RN Storybook got to where it is today and where its going. Full playlist in the thread. youtu.be/Uk93n-iIbHQ?si…
