Web application (PWA) for the dance community enabling matchmaking, chat, and video file exchange directly via WebRTC (peer-to-peer). **P2P video exchange app for the dance community** - matchmaking, chat, and WebRTC file transfer directly between users.
## 🚀 Features ---
### ✅ Implemented ## 🎯 What is this?
**Authentication & Security:** Web application (PWA) enabling dance event participants to:
- ✅ **JWT Authentication** - real authentication with bcrypt password hashing - Find recording partners via smart auto-matching
- ✅ **Email Verification** - email verification via AWS SES (link + PIN code) - Exchange competition videos peer-to-peer using WebRTC
- ✅ **Password Reset** - complete password reset workflow - Rate collaborations and track partnership history
- ✅ **WSDC Integration** - auto-fill data from worldsdc.com during registration - Chat in real-time (event rooms + private 1:1 messages)
- ✅ **Event Slugs** - unique alphanumeric identifiers preventing ID enumeration attacks
**User Profiles:** **Key Feature:** Direct browser-to-browser video file transfer using WebRTC DataChannel - no files stored on server, end-to-end encrypted (DTLS), tested up to 700MB+.
- ✅ **User Profiles** - profile editing (first name, last name, WSDC ID)
- ✅ **Social Media Links** - YouTube, Instagram, Facebook, TikTok
- ✅ **Location** - country (dropdown with 195 countries with flags) and city
- ✅ **Public Profiles** - visible to other logged-in users at /@{username}
- ✅ **Profile Statistics** - number of matches, average rating, number of reviews
- ✅ **Clickable Usernames** - usernames in chat are clickable links to public profiles
**Events & Chat:** ---

## 🧰 Admin CLI ## 🧰 Admin CLI
Use an in-container admin console for quick maintenance. Quick operations via REPL or command mode:
- Start REPL (default): `docker compose exec backend npm run cli`
- Explicit REPL: `docker compose exec backend npm run cli -- repl`
- List users: `docker compose exec backend npm run cli -- users:list --limit 20`
- Create user: `docker compose exec backend npm run cli -- users:create --email admin@example.com --username admin --password 'Secret123!'`
- Verify email: `docker compose exec backend npm run cli -- users:verify --email admin@example.com`
- List events: `docker compose exec backend npm run cli -- events:list --limit 10`
- Import WSDC (calendar/list) dry-run: `docker compose exec backend npm run cli -- events:import:wsdc --dry-run --since 2024-01-01 --until 2024-12-31`
- Import with location from list: `docker compose exec backend npm run cli -- events:import:wsdc --source list --limit 50`
- Enrich missing location: `docker compose exec backend npm run cli -- events:import:wsdc --source list --update-missing-location`
- Event details by slug: `docker compose exec backend npm run cli -- events:details --slug warsaw-dance-2025 [--participants 25]`
- Event participants: `docker compose exec backend npm run cli -- events:participants --slug warsaw-dance-2025 --limit 100`
- Event participants CSV: `docker compose exec backend npm run cli -- events:participants --slug warsaw-dance-2025 --limit 200 --csv > participants.csv`
- List matches: `docker compose exec backend npm run cli -- matches:list --limit 20 [--status accepted|pending|completed]`
- Check-in user to event (simulate QR): `docker compose exec backend npm run cli -- events:checkin --username john_doe --slug warsaw-dance-2025`
- App logs (if LOG_FILE configured): `docker compose exec backend npm run cli -- logs:app --lines 200`
- Recent chat messages: `docker compose exec backend npm run cli -- logs:messages --limit 50`
Production equivalents use `backend-prod` instead of `backend`.
REPL specifics:
- Inside REPL use `run('users:list --limit 20')` or `.cli users:list --limit 20`.
- Top-level await works for Prisma: `await prisma.user.findMany({ take: 5 })`.
- CLI errors in REPL do not exit the session; the error is printed so you can correct and retry.
