Phase 1 - Step 3: Authentication API **Backend Authentication:** - bcryptjs for password hashing (salt rounds: 10) - JWT tokens with 24h expiration - Secure password storage (never expose passwordHash) **API Endpoints:** - POST /api/auth/register - User registration - Username validation (3-50 chars, alphanumeric + underscore) - Email validation and normalization - Password validation (min 6 chars) - Duplicate email/username detection - Auto-generated avatar (ui-avatars.com) - POST /api/auth/login - User authentication - Email + password credentials - Returns JWT token + user data - Invalid credentials protection - GET /api/users/me - Get current user (protected) - Requires valid JWT token - Returns user data + stats (matches, ratings) - Token validation via middleware **Security Features:** - express-validator for input sanitization - Auth middleware for protected routes - Token verification (Bearer token) - Password never returned in responses - Proper error messages (no information leakage) **Frontend Integration:** - API service layer (frontend/src/services/api.js) - Updated AuthContext to use real API - Token storage in localStorage - Automatic token inclusion in requests - Error handling for expired/invalid tokens **Unit Tests (30 tests, 78.26% coverage):** Auth Endpoints (14 tests): - ✅ Register: success, duplicate email, duplicate username - ✅ Register validation: invalid email, short password, short username - ✅ Login: success, wrong password, non-existent user, invalid format - ✅ Protected route: valid token, no token, invalid token, malformed header Auth Utils (9 tests): - ✅ Password hashing and comparison - ✅ Different hashes for same password - ✅ JWT generation and verification - ✅ Token expiration validation - ✅ Invalid token handling All tests passing ✅ Coverage: 78.26% ✅

Testing
Tests are written using:
- Jest - Test framework
- Supertest - HTTP assertions
Run tests:
npm test
Current test coverage:
- Health check endpoint
- 404 error handling
- CORS configuration
- JSON body parsing
Docker
Build and run with Docker Compose (from project root):
docker compose up --build
Backend will be available at:
- Internal: http://backend:3000
- Through nginx: http://localhost:8080/api
Next Steps
- ✅ Basic Express setup
- ✅ Health check endpoint
- ✅ Unit tests
- ⏳ PostgreSQL connection
- ⏳ Database schema and migrations
- ⏳ Authentication (JWT + bcrypt)
- ⏳ Socket.IO for real-time chat
