Separate concerns - move Socket.IO and form logic from components to reusable hooks
New Hooks:
- useForm: Generic form state management with handleChange/handleSubmit/reset
- useEventChat: Extract Socket.IO logic from EventChatPage (156 lines)
* Manages messages, active users, connection state
* Handles send message, load older messages with scroll preservation
* Real-time updates via Socket.IO event listeners
- useMatchChat: Extract Socket.IO logic from MatchChatPage (115 lines)
* Manages 1:1 chat messages and connection
* Loads message history from API
* Real-time message sync via Socket.IO
Pages Refactored:
- EventChatPage: 661 → 564 lines (-97 lines, -15%)
- MatchChatPage: 517 → 446 lines (-71 lines, -14%)
Benefits:
- Cleaner component code - UI separated from business logic
- Reusable hooks can be used in other components
- Easier to test - hooks can be unit tested independently
- Better code organization - single responsibility principle
- 168 lines eliminated from pages, moved to 271 lines of reusable hooks
Phase 2 Total: -168 lines
Grand Total (Phase 1+2): -389 lines (-12%)
- Add Alert component with 4 variants (success/error/warning/info)
- Add LoadingSpinner and LoadingButton components
- Add FormInput and FormSelect components with icon support
- Add Modal and ConfirmationModal components
- Add ChatMessage, ChatMessageList, and ChatInput components
- Add EventCard component
These components will eliminate ~450 lines of duplicated code across pages.
Part of Phase 1 (Quick Wins) frontend refactoring.
CONTEXT.md updates:
- Changed 'Planned' to 'Implemented' for backend, db, and WebRTC
- Updated Docker Compose components - all services now implemented
- Updated database models section with actual schema
- Updated tech stack - removed 'Planned' labels
- Added test coverage stats (223/223 tests passing)
- Updated Last Updated date to 2025-11-20
- Added MVP complete status
ARCHITECTURE.md updates:
- Updated architecture diagram - marked backend and db as ✅ IMPL
- Changed 'Planned Services' to 'Implemented Services'
- Added production Dockerfile info
- Added test coverage (223/223 passing, 71%)
- Added Prisma ORM details
- Updated Last Updated date to 2025-11-20
- Added production-ready status
Both files now accurately reflect the completed MVP state.
- All 223/223 backend tests now passing (100%)
- Code coverage improved to 71% (from ~43%)
- Updated progress to ~95% (from ~90%)
- Removed 'improved test coverage' from What's Missing
- Added test isolation achievement to Phase 3 status
- Replace deleteMany({}) with selective deletion by username/email/slug in:
- events.test.js (target specific test users/events only)
- matches.test.js (target specific test users/events only)
- csrf.test.js (target csrftest user only)
- Replace delete() with deleteMany() for resilient cleanup:
- matches.test.js (2 inline cleanups)
- socket-webrtc.test.js (1 inline cleanup)
- Update TODO.md with test status and future UX/UI improvements
Test improvement: 189/223 passing (84.8%), up from 145/223 (65%)
- Replace delete() with deleteMany() in all afterAll hooks (more resilient)
- Add checks for testUser existence before creating EventParticipant
- Add .catch() handlers to ignore duplicate or foreign key errors
- Add conditional checks with ?. before cleanup operations
Changes improve test isolation and prevent foreign key constraint
violations when tests run together. All socket tests now pass
individually (12/12 socket.test.js, 7/7 socket-webrtc.test.js).
- Fixed CORS test in app.test.js to use allowed origin
- Updated auth-phase1.5.test.js to match actual error messages
- Fixed socket.test.js to use slug parameter instead of eventId
- Added EventParticipant records for socket event room tests
- Updated security config to allow both frontend origins in dev
All socket tests now passing (12/12). Test changes ensure proper
cleanup and prevent database conflicts by using selective deletion
instead of wiping entire tables.
Replace deleteMany({}) with selective cleanup targeting only test data:
- events.test.js: Delete only test users (john_dancer, sarah_swings, mike_blues)
and test events (test-dance-festival-2025) before creating new ones
- matches.test.js: Clean up john_dancer, sarah_swings, mike_moves and
test-dance-festival slug specifically
- users.test.js: Remove only john_dancer and sarah_swings test users
in both beforeAll and afterAll hooks
- auth.test.js: Target specific test usernames/emails (testuser, newuser,
lockouttest, etc.) instead of all users
- auth-phase1.5.test.js: Clean up 12 specific test users by username/email
- socket.test.js: Add beforeAll cleanup for sockettest user to prevent
conflicts from previous test runs
- socket-webrtc.test.js: Clean up webrtc_user1 and webrtc_user2 before
creating them
Fix CORS configuration for tests:
- security.js: Add http://localhost:3000 to allowed origins in development
mode to fix app.test.js CORS test (was failing with 500 error)
Results: Improved from 125/223 passing to 137/223 passing (12 more tests fixed)
All test data cleanup now uses WHERE clauses with specific usernames/emails/slugs
instead of wiping entire tables with deleteMany({})
- Update auth.test.js to match current API error messages
- Registration success message includes email verification notice
- Duplicate credentials use generic message to prevent user enumeration
- Add test commands to Makefile
- make test: run all backend tests
- make test-watch: run tests in watch mode
- make test-coverage: run tests with coverage report
All auth tests now pass (19/19 ✓)

Implemented complete WebRTC peer-to-peer file transfer system for match chat:
**Core WebRTC Implementation:**
- Created useWebRTC hook with RTCPeerConnection and RTCDataChannel
- P2P file transfer with 16KB chunking for large files (tested up to 700MB)
- Real-time progress monitoring for sender and receiver
- Automatic file download on receiver side
- End-to-end encryption via DTLS (native WebRTC)
- ICE candidate exchange via Socket.IO signaling
- Support for host candidates (localhost testing)
**WebRTC Detection & User Experience:**
- Automatic WebRTC capability detection on page load
- Detects if ICE candidates can be generated (fails in Opera, privacy-focused browsers, VPNs)
- User-friendly warning component with fix suggestions
- Graceful degradation: disables WebRTC button when blocked
- Suggests alternative methods (video links via Google Drive/Dropbox)
**Socket.IO Improvements:**
- Fixed multiple socket instance creation issue
- Implemented socket instance reuse pattern
- Disabled React.StrictMode to prevent reconnection loops in development
**Technical Details:**
- RTCPeerConnection with configurable STUN servers (currently using localhost config)
- RTCDataChannel with ordered delivery
- Comprehensive logging for debugging (ICE gathering, connection states, signaling)
- Match room-based signaling relay via Socket.IO
- Authorization checks for all WebRTC signaling events
**Files Changed:**
- frontend/src/hooks/useWebRTC.js - Complete WebRTC implementation

- ✅ Detection working in Opera (shows warning when WebRTC blocked)
- ✅ P2P connection establishment and DataChannel opening
- ✅ File chunking and progress monitoring
