Learn REACT-NATIVE-REANIMATED with Real Code Examples
Updated Nov 26, 2025
Performance Notes
Use shared values for realtime updates
Move heavy logic to worklets
Avoid JS thread interruptions
Offload gesture animations to UI thread
Reuse animated styles where possible
Security Notes
UI thread runs isolated worklets
No external code execution allowed
Animations cannot access sensitive data
Worklets are sandboxed from JS thread
Safe for production mobile apps
Monitoring Analytics
Monitor dropped frames on animations
Track JS thread load separately
Measure gesture responsiveness
Log animation durations
Profile device performance
Code Quality
Avoid side effects inside worklets
Keep shared values minimal
Use custom hooks for reuse
Document gesture logic
Test animations visually and on devices
