I know this isn’t my usual @expo.dev or React Native content, but I’m asking for your help from the bottom of my heart. My friends wife has just been diagnosed with an aggressive cancer. Every small donation helps. If you can’t donate, please help spread the word and share. 🫶🏼 gofund.me/84ee0b401

PSA: This is really hard to write. My close friend Nima’s wife, Lourensa (30), was diagnosed with rare, aggressive cancer (T-LBL). Chemo has started. Two young kids and a newborn. They’re facing the scariest months of their lives. If you can donate or share, it helps. gofund.me/d3bc15126

Zeego fails to compile for you with useFrameworks: static? I got you! gist.github.com/hirbod/4b0b0... @kudochien.dev maybe you know a better solution for this, I think you know best whats up. Not happy with this dangerousMod but at least it unblocks plenty people

I had a lot of moments reconsidering life choices or just raising alpacas instead of migrating, but it’s finally done. New architecture, @expo.dev SDK 53 (RN 0.79.1), and the fastest React Native app we’ve ever built (and I’ve ever seen!). Thanks to all contributors. Amazing achievement.

I was exploring a hard to debug memory leak in react native for at least 6 hours today. Turns out that when you don't add accessibilityLabel to RectButton or Pressable, it will fucking traverse all children to find a Text node or View with accessibilityLabel. This is insane. 1/4

Hey @samuel.bsky.team and @danabra.mov and @tazsingh.com and @mojavad.bsky.social. @peterp.bsky.social is in London for a few weeks. Super smart and humble guy. He also worked with @hailey.at on new arch for Bluesky. Y’all should definitely meet! Lots of synergy!

@samuel.bsky.team worth a try, no? github.com/Expensify/Ap... github.com/facebook/rea...

Does any @react.dev know why const Text = forwardRef((props, ref) => { return createElement('RCTText', { ...props, ref }) }) as ComponentType<TextProps> is causing There was an error during concurrent rendering but React was able to recover by instead synchronously rendering the entire root.]

The 5th edition of our React Native & @expo.dev- focused conf is coming closer and we're now accepting talks proposals! 🚨 If you have an interesting perspective on RN hot topics or you've come up with a solution for a common pain point & want to share your insights -> apply at appjs.co

Am I taking it too far with @swmansion.com CSS animations? It’s so fun. I am definitely pushing the limits with this example. I love REA v4. Such an amazing beta release. Mark my words: pretty sure this example will run at 60fps soon! Gist: gist.github.com/hirbod/48e45...

Runs on @expo.dev custom dev client and @swmansion.com Reanimated v4 CSS Animations. Was 5 min initial work and a few minutes to understand sync measurement with Fabric :D If you want to play with it: gist.github.com/hirbod/dc161... The future is React Native.

RIP to our beloved companion. The last six months have been incredibly difficult for our family, and now we have lost another family member. We will always cherish the memories and unconditional love you gave us. You’ll forever be in our hearts.

Imagine we used to write animations like this. @swmansion.com has come a long way.

This is the most important update to Reanimated since worklets. Really proud of the team 🐎

Congrats to swm on this release. Makes great animations in RN so much more accessible to people coming from a web development background.

Hello everyone! For the past few months, I’ve been working on an exciting new feature in React Native Reanimated at Software Mansion, and today, I’m thrilled to announce that CSS Animations and Transitions are now available in Reanimated 4 Beta! 🖌️✨ Read more 👇

There it is. I saw it live at React Native London Conf and couldn’t believe my eyes. I was invited to a private beta to test it, and it works like a charm. The next game-changer is here: use the full CSS spec in React Native. A new era of animations has been unlocked.

Legend List 1.0 beta is ready! It started as a performance experiment, but it ended up solving a lot of the major issues with lists in React Native. 🎉 ✨ Better perf than FlashList ✨ maintainContentVisiblePosition ✨ Bidirectional infinite lists ✨ Chat UI without inverting

Don't get me wrong, Bluesky, but you need to handle the bots. It’s worse than Twitter. Half my followers aren’t tech-related—wellness accounts, veterans, trans individuals, Democrats. No hate, but this isn’t the tailored audience I have on Twitter. It also feels too political. I'm a tech guy!

Randomly exploring github.com/IvanIhnatsiu... by x.com/I__Ihnanstiuk, and it's the best input mask library I've seen so far (besides the amazing markdown input by @tomekzaw.bsky.social). It handles everything natively without flickering. 👨‍🍳 💋

Hey @aman.bsky.social or @expo.dev -> That special example with GOOGLE_SERVICE docs.expo.dev/eas/environm... won't work, if you run `eas build --local` and you try to access a hidden file from .eas/.env/ You need to actually prefix it ${process.env.PWD} in that case.

Something's coming. This week. 🏇

Monorepo user? Thank me later: jamiemason.github.io/syncpack/ Makes npx lerna-update-wizard look like a fucking joke.

I recently moved away from Patreon and built Demos to share my React Native animations. Here’s a quick thread about the tech stack I used 🧵

Get children they said, it will be fun they said.

Threads Holo Ticket with React Native Skia. Available on Demos 🎟️

Just ran into another edge-to-edge issue, this time caused by <Modal />. @zoontek.me fixed the problem in the core, but until 0.77 is out, I just used react-native-z-view by @nishan.dev, and it works like a charm once again. 🙂

I'll be in SF (and in the US for the first time!) with my team from around February 1st to 9th. Would love to hang out! Who wants to meet up? Any @expo.dev or React Native folks around?

The new iOS Photos app is one of the worst pieces of software in iOS history. I hate it so much.

🚢 @tanstack.com Query v5.63.0 ships with a great new feature: The ability to unsubscribe an observer from the cache. This will hopefully help in react-native, where screens might stay mounted even if they aren't visible. Unsubscribing makes sure those don't re-render and won't trigger fetches.

You can find more on how that works in the React Native guides in our docs. Thanks @hirbod.dev for working on this with me and flodlc for contributing the docs 🙌

I've reached feature parity across all containers. My media parser now extracts all fields and has much better performance using BitReader, DataView, and caching. I might explore streaming instead of loading the entire file into memory for parsing. 🧵

The effort it took me to come this far is indescribable. My JS parser is almost on par (at least for the most common codecs) with FFProbe. Almost all fields are now resolved. WebM/Matroska is missing color and HDR detection. Once that's done, I’ll consider AVI/TS.

I was going back and forth with Claude on a very specific problem for like 30 minutes, and it kept getting worse with every iteration. I threatened that something "really bad" would happen if it messed up one more time, and it just gave me a working fix. What is this bullshit? 😂

Does anyone have a Big Buck Bunny archive that offers a wide variety of formats, codecs, resolutions, frame rates, HDR options, container formats, and other variations? (Or any other free video file)

Alright, I successfully extracted all the media fields I could natively pull on iOS and Android with ease, now using a fully custom media parser in TS. Next, I just need to map those cryptic codec names to more common values and add the audio bitrate (e.g., 320kbps).

Wow, @danabra.mov is cooking :D gist.github.com/paulmillr/26...

My media parser processes 29 videos (2.41 GB) in ~1 second, extracting key metadata without <video />. It’s not 100% accurate yet for all fields, but it’s blazing fast, and I’m working to make it the fastest in the world!

Please boycott PayPal and delete the Honey extension (though I never had it installed but I am (was until 10min ago) a heavy PayPal user.). www.youtube.com/watch?v=vc4y... This might be the biggest and dirtiest scam in internet history and affiliate marketing.

Updated expo-video-metadata github.com/hirbod/expo-... Now correctly retrieves the video orientation, natural orientation (before transformations), aspect ratio, and a boolean that indicates whether the video is 16:9. iOS, Android, Web.

Want to open your @expo.dev prebuilt iOS project in Xcode quickly? Just type `xed ios` in your terminal at the app root.

How should library authors handle React Native/ @expo.dev modules that only run on native (iOS/Android) when used on the web? 1) Fail (link error), user needs to wrap Platform.OS 2) Export a web version but Throw 3) Export no-op for web 3 would prevent errors but simply do nothing when invoked

react-native-volume-manager is much more than a volume listener. Plays super nice with @expo.dev expo-video (not expo-av) and let you enable and disable the audio session and category, informs the OS in a way so your music can resume automatically, too. (AppState, useLayoutEffect etc)

Finally released react-native-volume-manager v2, which fixes plenty of bugs and supports the new architecture. github.com/hirbod/react... Requires React Native 0.76+ or @expo.dev SDK 52+

LFG

One of the best React Native animation resources out there—beautifully crafted, clean, and stunning. Sign up, worth every penny!

@expo.dev Why not ask for local device search permission in expo-dev-client before the first QR scan? The app never works on the first install. I always have to scan the QR code, restart the app, then grant permission. Just prompt for it upfront! I wanted to ask for this 2 years now

Amazing achievement! Reveal animations are also solved with viewability tracking. Two little things left for a perfect library: - bi-directional scrolling events - layout animation support (we had some great ideas yesterday) Please support Jay and sponsor him. github.com/sponsors/jme...

Can the Bsky Team just buy this domain already? I think I'll update my hosts file to redirect it to bsky.app. I've opened this site by mistake at least 50 times already.

Handing over a Samsung A13 to the legend @jayz.us for the upcoming LegendList and discussing features and APIs in Frankfurt :)
