My account @patrickkabwe_ was recently suspended for “inauthentic behavior.” 😥

For those seeing my profile for the first time I’m a software engineer passionate about building mobile apps with @reactnative, creating native modules, and contributing to NitroModules by @mrousavy.

I love collaborating, learning, and growing alongside other developers in the community. Looking to connect, collaborate & grow!

A few years ago, this would've been a native-only feature.

Now you can build real-time video effects, virtual backgrounds, Center Stage, and Air Draw all in React Native.

@RiteshRk14 breaks down how he built it with VisionCamera, LiveKit, and WebRTC 👇

[Ritesh Shukla @RiteshRk14]

A common misconception is that Nitro Fetch is only faster because of prefetching.

Across every scenarios, we're seeing roughly 15–25% performance improvements.

Free performance. No API changes. Just swap it in and enjoy.

Who said React Native is slower than "native"? 🤔❌

Left: Native (by @Google)
Right: React Native (our client @humandco)

@bekacru my unreleased go better auth https://t.co/ww5X1QX7Eb fully compatible with better auth clients

Your React Native WebSocket only starts connecting once your JS runs.

NitroWebSockets prewarms the socket on app launch--so it's OPEN by the time your first screen renders.

Built-in: ~1s → Prewarmed: ~130ms 👇

Your gateway to building high-performant react native apps

[Margelo @margelo_com]

We just released react-native-runtimes! 🥳
👉 Render React components on separate JS Runtimes
👉 Share state (Zustand) across Runtimes, synced in C++
👉 Dual-Thread-approach for rendering/business logic
We plugged this into MetaMask which made the app start substantially faster:

Super clean designs from @margelo_com

@RiteshRk14 Congrats!

[Patrick Kabwe @_patrickkabwe]

It's been a long time coming, but finally it's here 🕺🏼

[Margelo @margelo_com]

We're finally publishing our #reactnative agent skills 🥳
Whether it's efficient Nitro Modules syntax, properly GPU-accelerated VisionCamera code or react-native-mmkv usage - the agent skills make sure you're not shipping AI slop to production - try them today:

[Patrick Kabwe @_patrickkabwe]

@zeddotdev @danilobleal Looking forward 🚀

[Marc @mrousavy]

Closing the feedback loop makes you a 100x developer nowadays 📈
We set up fully automated tests to run VisionCamera V5 with various input/output/size/FPS/HDR combinations on real iPhones/Android devices via AWS Device Farm 🤯

[Szymon @Turbo_Szymon]

I found something interesting 👀

expo-modules rely on Kotlin reflection, and the initialization is noticeable on low-end androids.

On my device (Samsung A16), expo-updates takes about 200ms to init, and expo-image ~100ms.

The React Native community just got a new powerhouse of knowledge.

🚨 Margelo’s blog is now live.

Expect deep dives into internals, performance, architecture, tooling, case studies, vision camera, and pixel-perfect mobile engineering.

Built by engineers pushing the ecosystem forward.

Ever wondered why animations on #reactnative's new architecture were so laggy?
We partnered with the @discord team, found the bottlenecks, and helped make their mobile app feel buttery smooth.
Here’s the before/after 👇

@acooldora Will be present in the next one

[Marc @mrousavy]

In collab with @swmansion, VisionCamera V5 switched from 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚠𝚘𝚛𝚔𝚕𝚎𝚝𝚜-𝚌𝚘𝚛𝚎 to 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚠𝚘𝚛𝚔𝚕𝚎𝚝𝚜.
You can now mutate Reanimated SharedValues directly inside a Frame Processor. Instant UI feedback from worklet-side detection!
