Mobile Patterns
1. Cross-Platform Architecture
- Shared Core: Maximize business logic sharing between platforms using cross-platform frameworks (React Native, Flutter) or KMM (Kotlin Multiplatform Mobile).
- Platform-Specific UI: Respect platform conventions (iOS Cupertino vs Android Material) when appropriate, using platform-specific file extensions or conditional rendering.
2. Navigation Patterns
- Stack Navigation: Push new screens onto the stack and pop them off to go back.
- Tab Navigation: Provide quick access to top-level views.
- Drawer Navigation: Use a hidden side menu for secondary navigation.
- Deep Linking: Configure URLs that navigate directly to specific content within the app.
3. Native Module Integration
- Bridging: Write custom native code (Java/Kotlin or Objective-C/Swift) and expose it to JavaScript/Dart.
- Turbo Modules / JSI: (React Native) Use direct C++ integration for high-performance synchronous calls.
- Platform Channels: (Flutter) Communicate between Dart and native code securely.
4. Offline-First
- Local Database: Use SQLite, WatermelonDB, or Realm to persist data locally.
- Sync Strategies: Implement optimistic UI updates and background sync queues.
- Conflict Resolution: Handle data conflicts between local edits and remote server state.
5. Push Notifications
- FCM / APNs: Configure Firebase Cloud Messaging for Android and Apple Push Notification service for iOS.
- Rich Notifications: Include images, action buttons, and custom payloads in notifications.
- Badge Management: Keep the app icon badge count in sync with unread notifications.
6. Performance
- FPS Monitoring: Aim for 60fps (or 120fps) for smooth animations and interactions.
- Memory Management: Profile memory usage to avoid OOM (Out Of Memory) crashes, especially with image-heavy views.
- Startup Time: Optimize app load time by deferring non-critical initializations.
7. App Store & Deployment
- Metadata: Prepare compelling descriptions, keywords, and release notes.
- Screenshots: Generate localized, high-resolution screenshots for all required device sizes.
- Versioning: Follow semantic versioning and increment build numbers automatically.
8. CI/CD
- Fastlane: Automate beta deployments, releases, and screenshots.
- EAS (Expo Application Services): Manage builds and OTA (Over The Air) updates for React Native.
- Code Signing: Manage provisioning profiles and keystores securely.
- TestFlight / Play Console: Distribute beta builds to testers and manage the release tracks.
