Updated by Misbha G 5 months ago
**For Each Optimization Task, Follow These Steps:**
1. **Audit Current Implementation:**
- Use React DevTools Profiler to identify performance issues and note it
- Check the network calls and redux state changes using reactotron tool
2. **Implement Optimization:**
- Apply the specific optimization technique which we have in guideline
- Test the changes thoroughly
- Measure performance improvements
- Document the changes made
3. **Verify Improvements:**
- Run performance tests before and after
- Check for any regressions
- Ensure functionality remains intact
- Update documentation
4. **Code Quality Checks:**
- Run ESLint and fix warnings
- Ensure TypeScript strict mode compliance
- Follow consistent naming conventions
- Add proper error handling
5. **Testing:**
- Test on both iOS and Android
- Test on low-end devices
- Verify offline functionality
- Check memory usage
**Common Optimization Patterns:**
- **React.memo** for component memoization
- **useCallback** for event handlers
- **useMemo** for expensive calculations
- **FlatList optimization** with proper props
- **Redux selectors** with createSelector
- **Image optimization** with FastImage
- **Network caching** for API responses
- **Memory cleanup** in useEffect
**Performance Metrics to Track:**
- Component render count
- Memory usage
- Bundle size
- App startup time
- Screen transition time
- API response time
**Files to Always Check:**
- Remove console.log statements
- Fix ESLint warnings
- Add proper TypeScript types
- Implement error boundaries
- Add loading states
**Before Committing:**
- Test on real devices
- Check for memory leaks
- Verify no breaking changes
- Update documentation

**Note:** Each task should be completed independently and thoroughly tested before moving to the next one. Document all changes and performance improvements for future reference.
