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.

Imagine, that change made our app the snappiest and fastest react native app I've ever seen. The fucking FPS counter is finally going up, not down when tapping a button. :D

I added a simple "fuck off" as Label and the rare bug is gone. This is just madness and a really bad default by RNGH and React Native. 2/4

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

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.

I’m actually really proud so far. I know I could just use FFProbe or MediaInfoLib (WASM), but my aim was to get to the bottom of this using TS only - and it just worked™. MP4, MOV, MKV, WEBM - basically every video, audio, and ISO/IEC 23091-2:2021 mapping is supported.

Hirbod @hirbod.dev · 06/01/2025

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. 🧵

170

Hirbod @hirbod.dev · 03/01/2025

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.

Hirbod @hirbod.dev · 03/01/2025

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? 😂

240

Hirbod @hirbod.dev · 02/01/2025

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).

160

Hirbod @hirbod.dev · 31/12/2024

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!

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)

Hirbod @hirbod.dev · 12/12/2024

Yes, the VSCode extension is bad, and we had to disable import sorting; it wrecked our entire codebase. We ended up adding `"organizeImports": false` to `biome.jsonc` + changes in my image. I've never heard of oxlint. We'll also need to reinstall ESLint because of the React compiler.

"editor.codeActionsOnSave": {
"quickfix.biome": "explicit",
"source.organizeImports": "explicit",
"source.sortImports": "explicit",
"source.removeUnusedImports": "explicit"
},

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.

Discovered a bug with @expo.dev router and react-native-screens after upgrading to SDK52 (not seen with react-navigation v7). Navigating from a screen with a header to one without, containing a ScrollView, causes a layout shift when interacting with the view. github.com/expo/expo/is...

2 crazy weird and hard to debug problems in one week are too much. Property Text doesn't exist? Why does it only happen in release mode, after it was built with EAS, not when compiled locally? We used Text by Skia here. import { Text as SkiaText } .. fixed the issue. I think its Metro or NativeWind

We have to declare income or money transfers received from outside Germany or the EU to the @bundesbank.de. Their website and portal are absolute trash (like every German government site), and you can’t even submit declarations or reports on weekends. We call that Armutszeugnis

If you encounter inexplicable "foo of undefined" errors with @expo SDK52 in Android release mode only, ensure that you disable: EXPO_UNSTABLE_METRO_OPTIMIZE_GRAPH=0 Four hours of debugging. RIP. Unfortunately, this disables the new tree-shaking feature. CC @bacon.bsky.social

@samuel.bsky.team remember when I reported the issue with GIF? Happens on videos too. It definitely seems to trigger “pinch to zoom”. I can manually reproduce when I actually pinch the video and start dragging afterwards.

Hirbod @hirbod.dev · 20/11/2024

I think isStale is barely used. We have a really big codebase, and not a single use.

It’s kinda weird that I need to pull down to trigger “flick to dismiss”. It should also work when I flick up, similar to almost all Apps I know.

I am not a Threads fan (content/algo), but it’s a snappy and extremely well made App, not gonna lie. It’s super polished, physics feel so on point everywhere, and I am in love with this card. I already challenged @reactiive.io

Actually, I’m so tired 🥱. I’ve only been sleeping about 3 hours a night for the last two weeks, and it’s starting to show. But I’m still stoked for @reactnativelondon.co.uk! I hope Londons traffic won’t let me down, need to attend Rays workshop

I’ll start a little QA thread with findings and ideas if you don’t mind @samuel.bsky.team Disabling horizontal bouncing on the filter scrollview will make it play nicely with fullScreenGestureEnabled. My finger always hits this area when I try to swipe back. Imho that bounce adds no value

@samuel.bsky.team if I’d work for Bsky, I’d remove the white status bar on my first day and make it translucent, as it was intended to be used 😅

Secret Expert tip: It's amazing how much FPS you gain on @expo.dev / React Native by rendering directly with `RCTText` and `RCTView` - huge boosts for lists and initial mount time. We migrated many surfaces, seeing up to 20-30 extra FPS in performance gains! gist.github.com/hirbod/03d48...

Pro RN tip: If your app contains many images or videos, memory can deplete faster than usual. Treat this as an "extra", not a solution—use memory wisely by optimizing images and caching options. A config plugin for Android and an app.json flag for iOS. @expo.dev EAS also supports this entitlement!

const { withAndroidManifest } = require('@expo/config-plugins')

module.exports = function withAndroidLargeHeap(config) {
return withAndroidManifest(config, async (config) => {
config.modResults.manifest.application[0].$['android:largeHeap'] = 'true'

return config
})
}

"ios": {
"entitlements": {
"com.apple.developer.kernel.increased-memory-limit": true
},
}

What really helps with big multimedia apps (lots of videos, images etc), which BlueSky is or will be, is increasing heap with my config plugin and adding ios.entitlements: { 'com.apple.developer.kernel.increased-memory-limit': true } To your app config

Profiling with Android Studio. Since the light box isn’t a surface that stays mounted for a long time, the memory should free up after unmounting, but I’d still profile and check if memory is correctly freed up after usage.
