- Add device ID generation (unique per device, stored in localStorage)
- Extend player ID format to: {basePlayerId}:{deviceId}
- Enable cross-domain sync on same device while keeping devices isolated
- Update backend APIs to support new player ID format
- Maintain backward compatibility with legacy UUID format
This allows:
- Each device (Desktop, Android, iOS) to have separate game states
- Cross-domain sync still works on the same device (hoerdle.de ↔ hördle.de)
- Easier debugging with visible device ID in player identifier
- Remove localStorage for game states and statistics (backend only)
- Add API route to suggest player ID based on recently updated states
- Add async player ID lookup that finds existing IDs across domains
- When visiting a new domain, automatically find and use existing player ID
- Enables cross-domain synchronization between hoerdle.de and hördle.de
- Add PlayerState model to database schema for storing game states
- Create player identifier system (UUID-based) for cross-domain sync
- Implement API endpoints for loading/saving player states
- Refactor gameState hook to use backend storage with localStorage fallback
- Support synchronization between hoerdle.de and hördle.de
- Migration automatically runs on Docker container start
