## ✅ What's Complete & Working

- ✅ **Mobile UI** - All screens built and styled
- ✅ **Navigation** - Stack navigator fully configured

---

## ❌ What's Not Done Yet

- ❌ **API Integration** - Mobile app still uses hardcoded mock data
- ❌ **Audio Playback** - MediaPlayer is UI-only, no actual playback
- ❌ **Authentication** - Login doesn't call backend API
- ❌ **Data Persistence** - No AsyncStorage or local caching
- ❌ **Admin Pages** - Routes exist but pages are empty stubs
- ❌ **Error Handling** - No try/catch for API failures

cd /home/mathias/jukebox/jukebox

# 2. Install dependencies (if needed)
npm install

# 3. Start Expo development server
npm start

# 4. Choose platform
# Press 'a' for Android
# Press 'i' for iOS
# Press 'w' for web

# 5. Test these features:
✅ Navigate between all screens
✅ Like/unlike tracks (heart icon)
✅ Search in "Liked Tracks" screen
✅ Sort by: Date Added, Name, Length

## 🚀 Next Development Phases

### Phase 1: API Integration (Weeks 1-2)
```javascript
// Connect LibraryContext to API
useEffect(() => {
  fetch('/api/albums', {
    headers: { 'Authorization': `Bearer ${token}` }
  })
  .then(r => r.json())
  .then(data => setAlbums(data))
}, [token])
```

### Phase 2: Authentication (Week 3)
- LoginScreen → `/api/login`
- Store token in AsyncStorage
- Persist login across sessions

### Phase 3: Audio Playback (Weeks 4-5)
- Install `expo-av`
- Implement audio playback service
- Connect MediaPlayer to real playback

### Phase 4: Admin Panel (Weeks 6-7)
- Implement AlbumsPage (CRUD)
- Implement UsersPage (list/manage)
- Implement AlbumTracksPage (reorder/upload)

### Phase 5: Polish (Week 8)

## 💡 Development Tips

1. **Hot Reload**: Press `r` in terminal while app is running
2. **Debug State**: Use React DevTools browser extension
3. **Test on Device**: Use Expo Go app + QR code scanner
4. **Check Data**: Look at `src/data/library.js` first
5. **API Testing**: Use Postman collection: `jukebox-api.postman_collection.json`
6. **Component Patterns**: TrackRow is a good reference for list items
7. **Navigation**: Use `useNavigation()` hook in any screen

---

## 🔗 Important Files Reference

### Must Know
- `App.js` - Root component with navigation setup
- `src/contexts/LibraryContext.js` - Main state management
- `src/data/library.js` - Mock data (replace this with API)
- `admin_panel/src/services/api.js` - Good reference for API client

### Useful
- `www/api/API_QUICK_REFERENCE.md` - All endpoints
- `www/api/routes/api.php` - Route definitions
- `jukebox-api.postman_collection.json` - API testing

## 📞 Questions to Ask

1. **Data**: Where will album covers and audio files be stored? (S3, local, etc.)
2. **Playback**: Will audio be streamed or downloaded?
3. **Offline**: Do you need offline mode / local caching?
4. **Users**: Will this be multi-tenant or single user?
5. **Social**: Will there be sharing / collaborative playlists?
6. **Analytics**: Do you need usage tracking / analytics?
