Reanimated 4 Stable Release — the Future of React Native Animations We are publishing first stable version of Reanimated 4.0. Read to learn what’s new in this release and why it is so important.

We've just published Reanimated 4 stable. It took literally months to complete since we started working on it back in 2024.

We did it! You can finally use third-party libraries in worklets - with `react-native-worklets`.

You Might Not Need react-native-svg We took on the development of react-native-svg over three years ago. Since then, we’ve been addressing major issues, adding popular…

We’ve been deep into react-native-svg for over 3 years now. 🖼️ In that time, we’ve seen it used in all kinds of ways. Some are smart, some… not ideal.

So, we wrote a post on when RN SVG is a good fit, and when you might not actually need it.👇

The title sounds a bit familiar, is it a new article or a déjà vu?

I'm afraid there's no way to make format symbols invisible in live-markdown as this is one of the core principles that syntax is visible. However, we're working on another rich text editing solution for React Native so stay tuned!

Yep that was a typo, I meant "far less".

How React Native Reanimated Updates the Styles — a Deep Dive There are a lot of props and styles in React Native and they fall into different categories. We can distinguish Non-layout Props (UI)…

🐎 Reanimated’s custom props allowlist optimizes updates by categorizing UI & Native props.

Learn how to use addWhitelistedUIProps, addWhitelistedNativeProps, setNativeProps, and more to gain more control over your animations.👇

To be honest, this change affects performance way less than we anticipated. There's no change in fps on iOS and about 25% fps drop on Android, but this is just an artificial benchmark that animates 200 views at once which is far less than usually needed. Here's the PR: github.com/software-man...

Writing code that lands on devices worldwide is wild. Some React Native libraries hit 500 stars, others go to 5000+. What’s the secret sauce and how did it feel to @tomekzaw.bsky.social and @matipl01.bsky.social in the case of Reanimated? 🚀 hubs.li/Q03888Yt0

It’s time for the Llama generation speed benchmark! 🚀

We’ve compared quantized Llama 3.2 1B QLoRA and the full precision model.
Results:
⚡Quantized model: 9.56s
⌛Full precision model: 19.14s

It’s 2x faster with quantization! 📈

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.

React Native 0.77 is now available with Expo SDK 52 - Expo Changelog Check out new updates from Expo on the Expo changelog.

🤝 The React Native team announced 0.77 today and now we're announcing that SDK 52 supports it: expo.dev/changelog/20...

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.

Reanimated 4 adds support for CSS Animations and CSS Transitions.

This is a major milestone for React Native in terms of web alignment and developer experience.

Congrats to everyone involved! 👏

Following the success of last year's talk on micro-interactions, we are thrilled to announce our first-ever premium workshop, on April 1st, hosted by @piaskowyk.bsky.social and @bbloniarz.bsky.social from @swmansion.com!
