Add test-bot.js script that simulates a user participating in event chat for testing purposes.
Features:
- Authenticates as user via API
- Checks in to event using QR code token
- Connects to Socket.IO and joins event room
- Sends random messages at configurable intervals
- Auto-accepts recording suggestions
Usage from container:
docker compose exec backend sh -c 'API_URL=http://localhost:3000 node scripts/test-bot.js --email user@example.com --password pass --slug event-slug --interval 10'
- Add security headers to nginx (X-Frame-Options, CSP, etc.)
- Reduce client_max_body_size from 500M to 10M
- Add npm overrides to fix cookie vulnerability in csurf
- Make navbar sticky with full width
Both users.test.js and auth-phase1.5.test.js were failing due to
unique constraint violations on wsdc_id field when running after
other test suites. Added wsdcId to cleanup queries and proper
deletion of related data (messages, matches, eventParticipants).
- Create constants/statuses.js with MATCH_STATUS, SUGGESTION_STATUS
- Update routes/dashboard.js to use MATCH_STATUS
- Update routes/matches.js to use MATCH_STATUS

Allow event organizers to configure which divisions run in parallel
(same time slot) for accurate collision detection in the auto-matching
algorithm. Divisions in the same slot will collide with each other.
- Add scheduleConfig JSON field to Event model
- Add PUT /events/:slug/schedule-config API endpoint
- Update matching algorithm to use slot-based collision detection
- Add UI in EventDetailsPage for managing division slots

- Tab navigation in EventChatPage (Chat, Uczestnicy, Nagrywanie)
- Matching configuration in EventDetailsPage (deadline, run matching)
- matchingAPI functions in api.js
- Return registrationDeadline and matchingRunAt in GET /events/:slug/details
UI allows users to:
- View who will record their heats
- View heats they need to record
- Accept/reject suggestions
- Opt-out from being a recorder
- Set registration deadline (admin)
- Manually trigger matching (admin)
Implement algorithm to match dancers with recorders based on:
- Heat collision avoidance (division + competitionType + heatNumber)
- Buffer time (1 heat after dancing before can record)
- Location preference (same city > same country > anyone)
- Max 3 recordings per person
- Opt-out support (falls to bottom of queue)
New API endpoints:
- PUT /events/:slug/registration-deadline
- PUT /events/:slug/recorder-opt-out
- POST /events/:slug/run-matching
- GET /events/:slug/match-suggestions
- PUT /events/:slug/match-suggestions/:id/status
Database changes:
- Event: registrationDeadline, matchingRunAt
- EventParticipant: recorderOptOut
- RecordingSuggestion: new model for match suggestions
Allow participants to set their bib/competitor number per event.
Display as badge next to username in participant lists.

- Tracks rating completion status (rated by me/partner)
- Returns incoming/outgoing pending match requests
- Add comprehensive test suite (12 tests, 93% coverage)
- Add DASHBOARD_PLAN.md with full design documentation
Problem:
- User got "Chat room not found" error when trying to send messages
- Event ChatRooms were only created by seed script, not for manually
created events
- Event "Another Dance Event" (ID: 420) was missing its ChatRoom
Root Cause:
- Seed script (seed.js:179-188) correctly creates ChatRooms for events
- But events created outside of seed (CLI, manual DB insert) didn't
create ChatRooms
- Socket handler requires ChatRoom to exist before accepting messages
Solution:
1. Added defensive check in check-in handler (POST /api/events/checkin/:token)
2. Automatically creates ChatRoom if missing when first user checks in
3. Logs creation for debugging: "Created missing chat room for event: {slug}"
Impact:
- Existing events without ChatRooms will get them on next check-in
- Future manually-created events will work correctly
- No breaking changes - all 223 tests pass
Changes:
- backend/src/routes/events.js: Added ChatRoom existence check and
auto-creation logic (lines 256-272)
Note: Manually created ChatRoom for event ID 420 to fix immediate issue
- 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({})

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)
- Add backend entrypoint with automated Prisma migrations and client regeneration
- Add frontend entrypoint with dependency management
- Update Dockerfiles to use entrypoint scripts
- Ensures database schema stays in sync with Prisma Client after migrations
Replace sequential event IDs in URLs with unique alphanumeric slugs to prevent enumeration attacks. Event URLs now use format /events/{slug}/chat instead of /events/{id}/chat.
Backend changes:
- Add slug field (VARCHAR 50, unique) to Event model
- Create migration with auto-generated 12-char MD5-based slugs for existing events
- Update GET /api/events/:slug endpoint (changed from :id)
- Update GET /api/events/:slug/messages endpoint (changed from :eventId)
- Modify Socket.IO join_event_room to accept slug parameter
- Update send_event_message to use stored event context instead of passing eventId
Frontend changes:
- Update eventsAPI.getBySlug() method (changed from getById)
- Update eventsAPI.getMessages() to use slug parameter
- Change route from /events/:eventId/chat to /events/:slug/chat
- Update EventsPage to navigate using event.slug
- Update EventChatPage to fetch event data via slug and use slug in socket events
Security impact: Prevents attackers from discovering all events by iterating sequential IDs.
Backend:
- Add EventParticipant model to track user-event participation
- Create database migration for event_participants table
- Record participation when user joins event chat via Socket.IO
- Update GET /api/events to include isJoined flag for current user
- Sort events: joined events first, then by start date

- Create PublicProfilePage component with user stats and info
- Add getUserByUsername function to API service
- Add /:username route to App.jsx
- Display user info: name, location, stats, WSDC ID, social links
- Only show public data (no email or sensitive information)
- Accessible only to authenticated users
Users can now view public profiles of other users by visiting
/<username>. The profile displays stats, location, WSDC ID, and
social media links.

- Create database migration for social media link columns
- Add custom validators to ensure URLs contain correct domains
- Update profile page with social media input fields
- Include social media URLs in GET /api/users/me response
- Add icons for each social platform in the UI
Users can now add links to their social media profiles. Each field
validates that the URL contains the appropriate domain (e.g.,
instagram.com for Instagram, youtube.com/youtu.be for YouTube).
- Add useEffect to pre-fill profile form with current user data
- Add WSDC ID field to profile edit form with numeric validation
- Update backend to accept wsdcId in profile updates with null handling
