Optimize profile-related screens and components by implementing memoization and granular Zustand selectors to reduce unnecessary re-renders.
- **Performance Optimization**:
- Wrap `TabBar` in `React.memo` to prevent re-renders when parent components update.
- Refactor `UserProfileScreen` to use a memoized `ProfileListHeader` component, decoupling the user header from tab state changes.
- **State Management**:
- Replace object destructuring from `useAuthStore` with granular selectors (e.g., `useAuthStore((s) => s.logout)`) in `AccountDeletionScreen`, `EditProfileScreen`, `FollowListScreen`, and `SettingsScreen` to prevent re-renders on unrelated store changes.
- **Code Cleanup**:
- Remove redundant case logic in `useUserProfile` hook.
Refactor the navigation and header strategy by replacing native stack headers with a custom `SimpleHeader` component across most profile and detail screens. This provides a more consistent UI/UX and better control over layout behavior.
- Implement `SimpleHeader` component in `src/components/common`.
- Disable native header rendering in `app/(app)/(tabs)/profile/_layout.tsx` and `app/_layout.tsx`.
- Update profile sub-screens to use `SimpleHeader` and `StatusBar` from `expo-status-bar`.
- Refactor `PostDetailScreen` to use a custom header implementation for better integration with the post author information.
- Update `UserScreen` to wrap content in `SafeAreaView` with the new header.
- Adjust `AppBackButton` to support transparent backgrounds.
Implement Android foreground service to keep app alive in background for real-time message sync:
- Add withForegroundService expo config plugin for notification channel setup
- Add BackgroundSyncManager with REALTIME, BATTERY_SAVER, and DISABLED modes
- Add ForegroundServiceModule for native Android foreground service binding
- Refactor backgroundService to integrate foreground service and expo-background-task
Also refactor auth and profile screens to use dynamic theme colors:
- Replace hardcoded THEME_COLORS with colors.primary.main, colors.background.paper, etc.
- Add useResolvedColorScheme for dynamic StatusBar styling
- Update NotificationSettingsScreen with sync mode selection UI
BREAKING CHANGE: Switched from expo-background-fetch to expo-background-task, minimum background sync interval changed from 900s to 15min in config
Looking at the changes:
1. **New files**:
- `app/(app)/(tabs)/profile/account-deletion.tsx` - account deletion screen
- `app/(app)/(tabs)/profile/privacy-settings.tsx` - privacy settings screen
- `src/screens/profile/AccountDeletionScreen.tsx` - account deletion implementation
- `src/screens/profile/PrivacySettingsScreen.tsx` - privacy settings implementation
2. **Modified files**:
- Database changes: `LocalDataSource.ts`, `DatabaseManager.ts`, `DatabaseConfig.ts`, `MigrationManager.ts` - refactoring database layer (removing LockManager, simplified initialization, added retry logic)
- Auth store: `authStore.ts` - changed `initDatabase` to `switchDatabase`
- Auth service: `authService.ts` - added privacy settings and account deletion methods
- DTOs: `dto.ts` - added PrivacySettingsDTO, DeletionStatusDTO, VoteOptionDTO, VoteResultDTO types
- Navigation: `hrefs.ts` - added new href functions for privacy settings and account deletion
- Profile screens: `SettingsScreen.tsx`, `index.ts`, `_layout.tsx` - added new menu items and routes
- Various message screens - added keyboard handling props
- `app/_layout.tsx` - added CSS for mobile touch handling
- `CreatePostScreen.tsx` - fixed vote_options format
- `PostDetailScreen.tsx` - added type annotations for vote handling
- `MediaCacheManager.ts` - updated to use new expo-file-system API
- `VerificationSettingsScreen.tsx` - fixed type safety
- `AccountSecurityScreen.tsx` - styling refactoring
This is a multi-faceted change involving:
Database refactoring, new privacy/account deletion features, bug fixes, and UI improvements. The database changes appear to be refactoring without new functionality. The most significant changes are the privacy settings and account deletion features, plus bug fixes like the vote options format and mobile touch handling.
</think>
feat(profile): add privacy settings and account deletion screens
Add privacy settings and account deletion functionality with new screens and APIs. Refactor database initialization to use switchDatabase for user switching. Fix vote options format in post creation and add type safety to vote handling. Improve mobile touch handling in layout and message screens. Update media cache to use new expo-file-system API.
BREAKING CHANGE: Database initialization now uses switchDatabase instead of initDatabase for user switching
