## Integration Points
### Authentication
- Uses Clerk for user authentication
- User email from session claims
- Database operations tied to authenticated user
### Database
- Leverages existing DatabaseOperations for user management
- Uses CalendarOperations for event storage
- Stores OAuth tokens in user metadata
- Tracks sync timestamps and statistics
### Google Services
- GoogleAuthService for OAuth management
- GoogleContactsSyncService for contact operations
- GoogleCalendarClient for calendar API
- Reuses existing backend services
### UI Components
- Built with Shadcn UI components (Card, Button, Badge, etc.)
- Follows existing design patterns from the project
- TypeScript strict mode compliance
- Responsive design for mobile/desktop
## User Flow
### Initial Setup
1. User configures database and OpenAI credentials in Settings
2. Google Integration section appears in Settings
3. User clicks "Connect Google Account"
4. OAuth flow redirects to Google
5. User grants permissions (Contacts, Calendar, Gmail)
6. Callback stores tokens in user metadata
7. Connection status updates to "Connected"
### Contacts Sync
1. User selects sync direction (Import/Export/Both)
2. User toggles options (Dry Run, Force Full, LLM Dedup)
3. User clicks "Sync Now"
4. API processes sync with selected options
5. Results display with statistics
6. User can review imported/exported/updated counts
### Calendar Sync
1. User navigates to desired week
2. User clicks "Sync Week"
3. API fetches events from Google Calendar
4. Events stored in database with attendee linking
5. User clicks "View Events" to see synced events
6. Events display with details and attendees
### Dashboard Monitoring
1. User visits dashboard
2. Google Integration widget shows connection status
3. Quick stats display contacts and events synced
4. User can click "Manage" to access full sync interface
## Error Handling
### Connection Errors
- OAuth token expiration detection
- Automatic re-authentication prompts
- Clear error messages for connection failures
### Sync Errors
- Individual item error tracking
- Error list display (first 5 errors + count)
- Success/failure indicators
- Dry run validation
### API Errors
- HTTP status code mapping
- User-friendly error messages
- Fallback to empty states
- Loading state management
## Security Considerations
### OAuth Tokens
- Stored in encrypted user metadata
- Never exposed in API responses
- Cleared on disconnect
- Per-user isolation
### API Authorization
- Clerk authentication required for all endpoints
- User ID verification
- Database-level user isolation
- CORS protection
### Data Privacy
- No cross-user data sharing
- Secure credential storage
- HTTPS-only communication
- Token refresh handling
## Performance Optimizations
### Component Loading
- Lazy loading for heavy components
- Loading states during API calls
- Skeleton screens for better UX
- Debounced API requests
### Data Fetching
- Server-side rendering where possible
- Client-side caching for status checks
- Incremental sync support
- Batch operations for efficiency
### UI Responsiveness
- Optimistic UI updates
- Progress indicators during sync
- Async operation handling
- Error boundaries for graceful failures
## Testing Recommendations
### Component Tests
- Unit tests for each component
- Mock API responses
- User interaction testing
- Error state coverage
### Integration Tests
- End-to-end OAuth flow
- Sync operation validation
- Database integration
- API route testing

## Deployment Checklist
### Environment Variables
Ensure these are set in production:
```bash
GOOGLE_CLIENT_ID=your-client-id
GOOGLE_CLIENT_SECRET=your-client-secret
NEXT_PUBLIC_APP_URL=https://your-domain.com
TURSO_URL=your-database-url
TURSO_AUTH_TOKEN=your-database-token
OPENAI_API_KEY=your-openai-key
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=your-clerk-key
CLERK_SECRET_KEY=your-clerk-secret
```
### Build Steps
```bash
# Install dependencies
cd web && npm install
# Build production bundle
npm run build
# Test production build locally
npm start
# Deploy to hosting platform
# (Vercel, Railway, or your preferred host)
```
### Post-Deployment Validation
1. Test OAuth flow in production
2. Verify API endpoints respond correctly
3. Check database connectivity
4. Confirm Google API quotas
5. Monitor error logs
6. Test on multiple devices/browsers
## Support and Troubleshooting
### Common Issues
**Issue**: OAuth callback fails
**Solution**: Check GOOGLE_REDIRECT_URI matches configured callback URL
**Issue**: Sync returns no events
**Solution**: Verify Calendar API is enabled in Google Cloud Console
**Issue**: LLM deduplication not working
**Solution**: Check OPENAI_API_KEY is valid and has credits
**Issue**: Connection status stuck on "checking"
**Solution**: Clear browser cache and verify API routes are accessible
### Debug Mode
Enable debug logging:
```bash
# In browser console
localStorage.setItem('debug', 'google:*')
# In API routes
console.log('[Google API]', data)
```
