## Architecture

### Services

- **app**: Main SvelteKit application (port 3002)
- **websocket**: Bun-based WebSocket server for real-time features (port 8081)
- **postgres**: PostgreSQL database with pgvector extension
- **redis**: Redis for caching and pub/sub messaging

### Key Components

- **AMM Trading**: Automated Market Maker with constant product formula (x*y=k)
- **Real-time Price Updates**: WebSocket broadcasting for live price feeds
- **Comment System**: Real-time coin discussions
- **Prediction Markets**: AI-resolved betting on future events
- **Portfolio Management**: Track holdings across multiple coins
- **Admin Panel**: Manage promo codes and system settings

## Development

### Local Development

```bash
# Start only database and redis
docker compose up -d postgres redis

# Install dependencies and run main app
cd website
npm install
npm run dev

# Run websocket server (in separate terminal)
cd website/websocket
bun install
bun run src/main.ts
```

### Database Management

```bash
# Run migrations
docker compose exec app npm run db:migrate

# Open Drizzle Studio
docker compose exec app npm run db:studio

# Push schema changes
docker compose exec app npm run db:push
```

## Deployment Commands

### Manual Deployment

```bash
# Build and start all services
docker compose build --no-cache
docker compose up -d

# Check service status
docker compose ps

# View logs
docker compose logs -f

# View specific service logs
docker compose logs -f app
docker compose logs -f websocket
```

### Maintenance

```bash
# Restart all services
docker compose restart

# Stop services
docker compose down

# Clean rebuild (removes volumes - WARNING: deletes data)
docker compose down --volumes --remove-orphans
docker compose build --no-cache
docker compose up -d

# Update and redeploy
git pull
./build.sh
```

## Troubleshooting

### Common Issues

1. **Port conflicts**: Ensure ports 3002, 8081, 5432, 6379 are available
2. **Database connection**: Check DATABASE_URL format and postgres service status
3. **WebSocket issues**: Verify REDIS_URL and redis service connectivity
4. **File uploads**: Confirm S3/B2 credentials and bucket permissions

### Health Checks

```bash
# Check all container status
docker compose ps

# Test main app
curl http://localhost:3002

# Test websocket health
curl http://localhost:8081/health

# Check database connectivity
docker compose exec postgres pg_isready -U rugplay_user

# Check redis connectivity
docker compose exec redis redis-cli ping
```

### Log Analysis

```bash
# Follow all logs
docker compose logs -f

# Application errors
docker compose logs app | grep -i error

# WebSocket logs
docker compose logs websocket

# Database logs
docker compose logs postgres
```

## Production Considerations

### Security

- [ ] Change all default passwords and secrets
- [ ] Use strong PRIVATE_BETTER_AUTH_SECRET (minimum 32 characters)
- [ ] Configure firewall rules for exposed ports
- [ ] Use HTTPS in production (reverse proxy recommended)
- [ ] Rotate API keys and database credentials regularly

### Performance

- [ ] Configure PostgreSQL for your hardware
- [ ] Set up Redis persistence if needed
- [ ] Monitor container resource usage
- [ ] Configure log rotation
- [ ] Set up database connection pooling

### Monitoring

- [ ] Set up health check endpoints
- [ ] Configure log aggregation
- [ ] Monitor database performance
- [ ] Track WebSocket connection metrics
- [ ] Set up alerts for service failures

### Backup Strategy

- [ ] Database backups: `pg_dump` scheduled backups
- [ ] Redis persistence: Configure RDB snapshots
- [ ] File storage: S3/B2 versioning and backup
- [ ] Configuration: Version control for .env files (encrypted)
