Learn REACT-NATIVE-REANIMATED with Real Code Examples

Install: npm install react-native-reanimated

Enable Reanimated Babel plugin in babel.config.js

Add Reanimated's Babel plugin as last plugin

Ensure Hermes engine enabled for best performance

Add Reanimated's native code via pod install (iOS)

React Native 0.70+ recommended

Hermes engine enabled

Gesture-handler installed

Correct Babel plugin placement

Developer mode animations disabled for production feel

babel.config.js - Reanimated plugin setup

index.js - gesture handler & Reanimated setup

metro.config.js - optional optimizations

ios/android native configs as needed

tsconfig.json - type support for Reanimated

npm install react-native-reanimated

npx pod-install (iOS)

npm run android / ios

npx expo prebuild (for bare native code with Expo)

yarn start for metro server

Animations unaffected by language

Gesture directions may differ (LTR/RTL)

Use adaptive transitions for RTL layouts

Text-containing components translate normally

No text in worklets unless necessary

Animations respect reduced motion settings

Gestures must be keyboard-accessible (where applicable)

Avoid essential content behind animations

Provide alternative interactions for critical flows

Screen readers unaffected by animations

Animated styles modify transforms, opacity, layout

Works with standard RN styles

Supports smooth transitions and interpolation

Integrates with gesture-driven UI

Works with custom components and Skia

Shared values store animation state

Derived values compute reactive logic

Worklets manipulate state on UI thread

External React state interacts indirectly

Multiple animations can run in sync

Animation states remain in UI runtime

JS data must be serializable for worklets

Shared values bridge UI and JS threads

Avoid large objects in worklets

Lightweight updates ensure 60fps
