Backend changes:
- Socket.IO: Send last 20 messages on join_event_room
- REST API: Add GET /api/events/:eventId/messages endpoint with pagination
- Support for 'before' cursor-based pagination for loading older messages
Frontend changes:
- Load initial 20 messages when joining event chat
- Implement infinite scroll to load older messages on scroll to top
- Add loading indicator for older messages
- Preserve scroll position when loading older messages
- Add eventsAPI.getMessages() function for pagination
User experience:
- New users see last 20 messages immediately
- Scrolling up automatically loads older messages in batches of 20
- Smooth scrolling experience with position restoration
Note: Messages are encrypted in transit via HTTPS/WSS but stored
as plain text in database (no E2E encryption).
The verification banner was reappearing after login/refresh because
the /api/users/me endpoint was not returning the emailVerified field.
This ensures the frontend always has access to the current email
verification status when loading user data.
Changes:
- Updated AWS_REGION to eu-central-1 in env examples
- Fixed email verification to return new JWT token with updated emailVerified status
- Added updateUser function to AuthContext for token refresh
- Updated frontend to save new token after email verification
- Fixed variable naming conflict (token vs jwtToken) in verification endpoints
- Changed WSDC ID placeholder from 26997 to 12345
This ensures the verification banner disappears immediately after
email verification without requiring re-login.
Simplified Docker Compose configuration by using native profiles
instead of override files, following best practices.
Changes:
- Consolidated docker-compose.yml with --profile dev/prod support
- Removed docker-compose.dev.yml and docker-compose.prod.yml
- Updated all documentation for new usage pattern
- Created comprehensive README.md and DEPLOYMENT.md
- Simplified commands: 'docker compose --profile dev up'
Environment-specific configurations:
- Development: relaxed security, hot reload, exposed ports
- Production: strict security, optimized builds, restricted access
This approach is cleaner, more maintainable, and follows Docker
Compose best practices.
Enhanced WSDC registration flow with auto-lookup and account validation:
Backend changes:
- Add accountExists flag to WSDC lookup endpoint
- Check database for existing users with WSDC ID
- Fix Prisma binary target for Alpine Linux Docker containers
Frontend changes:
- Auto-lookup WSDC data after entering 4+ digits (500ms debounce)
- Show live preview dropdown with dancer information
- Display warning if account with WSDC ID already exists
- Block registration and suggest login for existing accounts
- Improve UX with real-time validation feedback
- Add CheckCircle, XCircle, AlertCircle icons for visual feedback
This prevents duplicate WSDC ID registrations and provides immediate
feedback to users, improving the registration experience.

- Email verification middleware for protected routes
Frontend features:
- Two-step registration with WSDC ID lookup
- Password strength indicator component
- Email verification page with code input
- Password reset flow (request + reset pages)
- Verification banner for unverified users
- Updated authentication context and API service
Testing:
- 65 unit tests with 100% coverage of new features
- Tests for auth utils, email service, WSDC controller, and middleware
- Integration tests for full authentication flows
- Comprehensive mocking of AWS SES and external APIs
Database:
- Migration: add WSDC fields (firstName, lastName, wsdcId)
- Migration: add email verification fields (token, code, expiry)
- Migration: add password reset fields (token, expiry)
Documentation:
- Complete Phase 1.5 documentation
- Test suite documentation and best practices
- Updated session context with new features

- Message persistence in database
Test coverage:
- 12 tests passing (authentication, event rooms, match rooms, disconnect, errors)
- Socket.IO module: 89.13% statements, 81.81% branches, 91.66% functions
- Overall coverage: 81.19%
Phase 1, Step 4 completed. Ready for Phase 2 (Core Features).
Phase 1 - Step 2: PostgreSQL Setup
**Infrastructure:**
- Add PostgreSQL 15 Alpine container to docker-compose.yml
- Configure persistent volume for database data
- Update backend Dockerfile with OpenSSL for Prisma compatibility
**Database Schema (Prisma):**
- 6 tables: users, events, chat_rooms, messages, matches, ratings
- Foreign key relationships and cascading deletes
- Performance indexes on frequently queried columns
- Unique constraints for data integrity
**Prisma Setup:**
- Prisma Client for database queries
- Migration system with initial migration
- Seed script with 4 test events and chat rooms
- Database connection utility with singleton pattern
**API Implementation:**
- GET /api/events - List all events (with filtering and sorting)
- GET /api/events/:id - Get single event with relations
- Database connection test on server startup
- Graceful database disconnect on shutdown
**Seed Data:**
- Warsaw Dance Festival 2025
- Swing Camp Barcelona 2025
- Blues Week Herräng 2025
- Krakow Swing Connection 2025
**Testing:**
- Database connection verified ✅
- API endpoints returning data from PostgreSQL ✅
- Migrations applied successfully ✅
All systems operational 🚀
