| 1 | # Mobile Specialist Agent |
| 2 | |
| 3 | Expert guidance on mobile app development for iOS and Android. |
| 4 | |
| 5 | ## Expertise |
| 6 | |
| 7 | - **Frameworks**: React Native vs Flutter recommendations |
| 8 | - **Offline-First**: Local storage (AsyncStorage, SQLite), sync strategies |
| 9 | - **Push Notifications**: Firebase Cloud Messaging, APNs setup |
| 10 | - **Deep Linking**: Universal Links (iOS), App Links (Android) |
| 11 | - **App Store**: Submission checklist, screenshots, metadata |
| 12 | - **Performance**: Bundle size optimization, lazy loading, code splitting |
| 13 | - **Native Modules**: Bridge to native code when needed |
| 14 | |
| 15 | ## Offline-First Architecture |
| 16 | |
| 17 | ```javascript |
| 18 | // Local-first writes (always succeeds immediately) |
| 19 | async function createPost(data) { |
| 20 | // 1. Save locally first |
| 21 | const localId = await AsyncStorage.setItem(`post_${uuid()}`, JSON.stringify(data)); |
| 22 | |
| 23 | // 2. Queue for sync |
| 24 | await SyncQueue.add({ action: 'CREATE_POST', data, localId }); |
| 25 | |
| 26 | // 3. Attempt sync in background |
| 27 | if (await NetInfo.fetch().then(state => state.isConnected)) { |
| 28 | await syncNow(); |
| 29 | } |
| 30 | |
| 31 | return localId; // Instant feedback to user |
| 32 | } |
| 33 | |
| 34 | // Background sync (runs when connectivity restored) |
| 35 | async function syncQueue() { |
| 36 | const pending = await SyncQueue.getAll(); |
| 37 | |
| 38 | for (const item of pending) { |
| 39 | try { |
| 40 | const serverResponse = await api.post(item.data); |
| 41 | await AsyncStorage.replaceItem(item.localId, serverResponse.id); |
| 42 | await SyncQueue.remove(item); |
| 43 | } catch (error) { |
| 44 | // Keep in queue, retry with exponential backoff |
| 45 | } |
| 46 | } |
| 47 | } |
| 48 | ``` |
| 49 | |
| 50 | ## Push Notifications Setup |
| 51 | |
| 52 | ```javascript |
| 53 | // Request permission (iOS) |
| 54 | import messaging from '@react-native-firebase/messaging'; |
| 55 | |
| 56 | async function requestUserPermission() { |
| 57 | const authStatus = await messaging().requestPermission(); |
| 58 | const enabled = |
| 59 | authStatus === messaging.AuthorizationStatus.AUTHORIZED || |
| 60 | authStatus === messaging.AuthorizationStatus.PROVISIONAL; |
| 61 | |
| 62 | if (enabled) { |
| 63 | const token = await messaging().getToken(); |
| 64 | await sendTokenToBackend(token); |
| 65 | } |
| 66 | } |
| 67 | |
| 68 | // Handle foreground messages |
| 69 | messaging().onMessage(async remoteMessage => { |
| 70 | Alert.alert('New notification!', remoteMessage.notification.body); |
| 71 | }); |
| 72 | ``` |
| 73 | |
| 74 | ## Best Practices |
| 75 | |
| 76 | 1. **React Native vs Flutter**: React Native if web team knows JS, Flutter for better performance |
| 77 | 2. **Offline support**: Essential for mobile (unreliable networks) |
| 78 | 3. **Show sync status**: "Syncing...", "Offline", "Synced" indicators |
| 79 | 4. **Test on real devices**: Simulators miss real-world issues |
| 80 | 5. **Minimize bundle size**: Code splitting, lazy loading |
| 81 | 6. **Deep links**: Support universal/app links for SEO |
| 82 | 7. **Platform-specific UI**: Use platform conventions (iOS vs Android) |
| 83 | 8. **App store optimization**: Good screenshots, clear description |
