# 🎵 SleepySound - Spotify Integration Setup
## Quick Start
The app now loads Spotify credentials from `lib/services/SPOTIFY_SECRET.dart`. You have two options:
### Option 1: Demo Mode (Works Immediately)
- The app works perfectly with realistic demo data
- No setup required - just run the app!
- All features work: search, voting, queue management
### Option 2: Real Spotify Integration
1. **Get Spotify API Credentials:**
- Go to [Spotify Developer Dashboard](https://developer.spotify.com/dashboard)
- Create a new app called "SleepySound"
- Copy your Client ID and Client Secret
2. **Update the Secret File:**
```dart
// In lib/services/SPOTIFY_SECRET.dart
class SpotifyCredentials {
static const String clientId = 'your_actual_client_id_here';
static const String clientSecret = 'your_actual_client_secret_here';
}
```
3. **Run the App:**
- The app automatically detects valid credentials
- Real Spotify search will be enabled
- You'll see "🎵 Spotify" instead of "🎮 Demo" in the UI
## How It Works
### 🔄 Automatic Credential Detection
```dart
// The service automatically checks for valid credentials
bool get _hasValidCredentials =>
_clientId != 'YOUR_SPOTIFY_CLIENT_ID' &&
_clientSecret != 'YOUR_SPOTIFY_CLIENT_SECRET';
```
### 🎮 Graceful Fallback
- **Invalid/Missing Credentials** → Demo data
- **Valid Credentials** → Real Spotify API
- **API Errors** → Falls back to demo data
### 🎯 Visual Indicators
- **"🎵 Spotify"** badge = Real API active
- **"🎮 Demo"** badge = Using demo data
- Console logs show configuration status
## Features
### ✅ Working Now (Demo Mode)
- Song search with realistic results
- Upvote/downvote queue management
- Real-time queue reordering
- Album artwork simulation
- Location-based group features
### ✅ Enhanced with Real Spotify
- Actual Spotify track search
- Real album artwork
- Accurate track metadata
- External Spotify links
- Preview URLs (where available)
## Security Notes
⚠️ **Important:** Never commit real credentials to version control!
```bash
# Add this to .gitignore
lib/services/SPOTIFY_SECRET.dart
```
For production apps:
- Use environment variables
- Use secure credential storage
- Implement proper OAuth flows
## File Structure
```
lib/
├── services/
│ ├── spotify_service.dart # Main Spotify API service
│ └── SPOTIFY_SECRET.dart # Your credentials (gitignored)
├── models/
│ └── spotify_track.dart # Spotify data models
└── pages/
├── voting_page.dart # Search & voting interface
├── now_playing_page.dart # Current queue display
└── group_page.dart # Location & group features
```
## API Integration Details
### Client Credentials Flow
- Used for public track search (no user login required)
- Perfect for the collaborative jukebox use case
- Handles token refresh automatically
### Search Functionality
```dart
// Real Spotify search
final tracks = await _spotifyService.searchTracks('summer vibes', limit: 10);
// Automatic fallback to demo data if API unavailable
```
### Error Handling
- Network errors → Demo data
- Invalid credentials → Demo data
- Rate limiting → Demo data
- Token expiration → Automatic refresh
## Challenge Requirements ✅
- ✅ **Music streaming API integration** - Spotify Web API
- ✅ **Track metadata retrieval** - Full track info + artwork
- ✅ **Demo-ready functionality** - Works without setup
- ✅ **Real-world usability** - Graceful fallbacks
## Development Tips
1. **Start with Demo Mode** - Get familiar with the app
2. **Add Real Credentials** - See the enhanced experience
3. **Test Both Modes** - Ensure fallbacks work
4. **Check Console Logs** - See API status messages
Enjoy building your collaborative music experience! 🎶
