react-native-reanimated

Why we included this project

React Native apps often need gestures and screen transitions that stay smooth even while JavaScript is busy, and Reanimated is where most teams land. The animation work runs on the UI thread instead of the JS bridge, which is what lets spring-based interactions track touch input at full frame rate rather than stuttering. Prebuilt helpers cover common cases like layout, opacity, and scroll-linked effects, so typical animations take a few lines instead of a hand-rolled native module. The companion Worklets package handles the multi-threaded execution that makes these animations responsive, and the two ship together from this repo. Expo users get a straightforward install path, and the maintained version targets the modern New Architecture rather than the legacy bridge.
