Reanimated 4 is here to change the way we build animations in React Native. With CSS-style animations and transitions, animations are now easier to write, more predictable, and work more like they do on the web.

In this episode, Ola Desmurs-Linczewska (https://x.com/p_syche_) sits down with Tomasz Zawadzki (https://x.com/tomekzaw_) and Mateusz Łopaciński (https://x.com/MatiPl01) from Software Mansion to discuss what’s new in Reanimated 4, why React Native is moving toward web standards, and what these changes mean for developers.

We talk about:

💜 Why Reanimated 4?—the motivation behind CSS-based animations and what problems they solve.

💜 How CSS animations & transitions work in React Native—use the syntax you already know!

💜 New Architecture-only support—why the old architecture is gone and what it means for migration.

💜 Aligning React Native with web standards—how Meta and the community are making React Native more like the web.

💜 Modularity and the future of Reanimated—splitting the library into smaller packages for better maintainability.

💜 Migration tips and developer experiments—how to upgrade, test new features, and start using CSS animations today.

Reanimated 4 is in beta now, so experiment with it and share your impressions in the comments!
