Animations That Feel Native: Reanimated and Gesture Handler Essentials

JavaScript-driven animations can miss frames under load. React Native Reanimated runs worklets on the UI thread when configured correctly, and React Native Gesture Handler provides recognizers that cooperate with native scroll views.

Worklets and shared values

Define animation logic as worklets so it executes outside the busy JS thread. Use shared values for properties you interpolate, and keep dependencies minimal.

Gestures and scroll conflicts

Compose pan, pinch, and tap gestures with proper simultaneous and race configurations. Test on Android and iOS—platform scroll physics differ.

Accessibility

Ensure motion respects reduced motion settings where applicable and that gesture-only interactions have accessible alternatives.
