Bug: EventChatPage referenced formatHeat() function in header's heat display
(line 365) but the function was removed during Phase 3 refactoring when
creating the HeatBadges component.
Solution:
1. Enhanced HeatBadges component with badgeClassName prop to support
custom styling (needed for dark header background)
2. Replaced manual heat rendering in EventChatPage header with
HeatBadges component
3. Passed custom badge styling to match the dark primary-700 header
Changes:
- HeatBadges.jsx: Added badgeClassName prop for style customization
- EventChatPage.jsx: Replaced manual heat map with HeatBadges component
Fixes: "Uncaught ReferenceError: formatHeat is not defined" error
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.

Changed WebRTC config from localhost-only to STUN servers:
- Removed rtcConfigLocalhost (no longer needed)
- Using rtcConfig with Google STUN servers
- Enables NAT traversal for users on different networks
- Removed unnecessary iceCandidatePoolSize config
- Link sharing remains as fallback for blocked users
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
- frontend/src/utils/webrtcDetection.js - WebRTC capability detection
- frontend/src/components/WebRTCWarning.jsx - User warning component
- frontend/src/pages/MatchChatPage.jsx - WebRTC integration
- frontend/src/services/socket.js - Socket instance reuse
- frontend/src/main.jsx - Disabled StrictMode for Socket.IO stability
**Testing:**
- ✅ Verified working in Chrome (ICE candidates generated)
- ✅ Tested with 700MB file transfer
- ✅ Detection working in Opera (shows warning when WebRTC blocked)
- ✅ P2P connection establishment and DataChannel opening
- ✅ File chunking and progress monitoring
**TODO:**
- Add STUN server configuration for production (NAT traversal)
- Consider server-based upload fallback for blocked users

6. Match marked as 'completed' when both users have rated
7. Users cannot rate the same match twice

Users could gain unauthorized access to event chats by refreshing the page after leaving an event. The socket handler was automatically creating participation records when users joined rooms, completely bypassing the QR code check-in requirement. This fix verifies that users have legitimately checked in before allowing socket room access.
Backend:
- Use _count.participants for accurate real-time participant count
- Remove reliance on stale participantsCount column
Frontend:
- Show check-in requirement message for non-joined events
- Display "Open chat" button only for joined events
- Add dev-only "View details" button for QR code access during testing
- Improve visual feedback with amber-colored check-in notice
This ensures the participant count reflects actual checked-in users
and prevents unauthorized access to QR codes in production while
maintaining developer convenience in development mode.
Backend:
- Add event_checkin_tokens table with unique tokens per event
- Implement GET /api/events/:slug/details endpoint (on-demand token generation)
- Implement POST /api/events/checkin/:token endpoint (date validation only in production)
- Implement DELETE /api/events/:slug/leave endpoint
- Add comprehensive test suite for check-in endpoints
Frontend:
- Add EventDetailsPage with QR code display, participant list, and stats
- Add EventCheckinPage with success/error screens
- Add "Leave Event" button with confirmation modal to EventChatPage
- Install qrcode.react library for QR code generation
- Update routing and API client with new endpoints
Features:
- QR codes valid from (startDate-1d) to (endDate+1d)
- Development mode bypasses date validation for testing
- Automatic participant count tracking
- Duplicate check-in prevention
- Token reuse for same event (generated once, cached)
