3. REST API Endpoints

All endpoints are accessible at https://echoesoftheashgame.patacuack.net/api/

Authentication

  • POST /api/auth/register - Register new user
  • POST /api/auth/login - Login with credentials
  • GET /api/auth/me - Get current user info

Game

  • GET /api/game/state - Get player state (HP, stamina, location)

4. PWA Features

  • ✅ Service Worker for offline capability
  • ✅ App manifest for install prompt
  • ✅ Responsive design (mobile & desktop)
  • ✅ Automatic update checking

5. Database Schema

Updated players table supports both Telegram and web users:

- telegram_id (integer, nullable, unique) -- For Telegram users
- id (serial, unique) -- For web users
- username (varchar, nullable, unique) -- Web authentication
- password_hash (varchar, nullable) -- Web authentication
- name, hp, max_hp, stamina, max_stamina
- strength, agility, endurance, intellect
- location_id, level, xp, unspent_points

Constraint: Either telegram_id OR username must be NOT NULL

🎨 Design & UX

Color Scheme

  • Primary: #ff6b6b (Sunset Red)
  • Background: Gradient from #1a1a2e to #16213e
  • Accent: rgba(255, 107, 107, 0.3)
  • Success: rgba(76, 175, 80, 0.3)
  • Warning: #ffc107

Responsive Breakpoints

  • Desktop: Full features, max-width 800px content
  • Mobile: Optimized layout, smaller compass buttons, compact tabs

UI Components

  • Compass Navigation: Central compass with directional buttons
  • Stats Bar: Always visible HP, Stamina, Location
  • Tabs: 4-tab navigation (Explore, Inventory, Map, Profile)
  • Message Box: Feedback for actions
  • Buttons: Hover effects, disabled states, transitions

🔐 Security

  • ✅ HTTPS enforced via Traefik
  • ✅ JWT tokens with 7-day expiration
  • ✅ Bcrypt password hashing (12 rounds)
  • ✅ CORS configured for specific domain
  • ✅ SQL injection prevention (SQLAlchemy parameterized queries)
  • ✅ XSS protection (React auto-escaping)

🐛 Known Limitations

  1. Inventory System: Currently disabled for web users due to foreign key constraints. The inventory table references players.telegram_id, which web users don't have. Future fix will migrate inventory to use players.id.

  2. Combat System: Not yet implemented in PWA API endpoints.

  3. NPC Interactions: Not yet exposed via API.

  4. Dropped Items: Not yet synced with web interface.

  5. Interactive Map: Planned for future release.

  6. Push Notifications: Not yet implemented (requires service worker push API setup).
