Deployment, Security & Performance Production ​

Production deployment architecture, security measures, and performance optimizations.

Deployment Architecture ​

  1. Vercel (Recommended)

    • Automatic HTTPS
    • Global CDN
    • Serverless functions
    • Zero-config deployment

  2. Docker

    • Full control
    • Easy scaling
    • Health check support
    • Multi-container orchestration

  3. Node.js + PM2

    • Traditional VPS deployment
    • Process management
    • Auto-restart on crash
    • Cluster mode support

See: Deployment Guide for detailed instructions.

Security Architecture ​

Authentication Security ​

Steam OpenID:

  • Official Steam authentication system
  • No password storage required
  • Secure token exchange
  • Session management with JWT

JWT Sessions:

  • HTTP-only cookies
  • CSRF protection
  • Short expiration times
  • Secure token signing

Best Practices:

typescript
// Server-side JWT configuration
const JWT_CONFIG = {
  expiresIn: '24h',
  algorithm: 'HS256',
  httpOnly: true,
  secure: true, // HTTPS only
  sameSite: 'lax'
}

API Security ​

Rate Limiting:

  • Prevents abuse
  • Per-IP and per-user limits
  • Configurable thresholds

Input Validation:

  • All inputs sanitized
  • Type checking with TypeScript
  • SQL injection prevention
  • XSS protection

CORS Configuration:

typescript
// Allowed origins only
cors: {
  origin: process.env.ALLOWED_ORIGINS?.split(','),
  credentials: true
}

Database Security ​

Connection Security:

  • TLS/SSL encrypted connections
  • Credential management via environment variables
  • Connection pooling with limits

Query Safety:

  • Prepared statements
  • Parameterized queries
  • ORM-style query builders
  • No raw SQL from user input

Access Control:

  • Least privilege principle
  • User-specific data isolation
  • Foreign key constraints
  • Cascade deletion rules

Environment Variables ​

Sensitive Data:

  • Never commit to repository
  • Use .env files (gitignored)
  • Production secrets in platform config
  • Rotate credentials regularly

Required Variables:

env
# Database
DATABASE_URL=mysql://user:pass@host:3306/dbname

# Steam API
STEAM_API_KEY=your_steam_api_key
STEAM_RETURN_URL=https://your-domain.com/api/auth/steam-callback

# JWT
JWT_SECRET=your_random_secret_key

# Environment
NODE_ENV=production

Performance Optimizations ​

Frontend Performance ​

Code Splitting:

  • Automatic route-based splitting
  • Dynamic component imports
  • Vendor bundle separation

Asset Optimization:

  • Minified JavaScript and CSS
  • Gzip/Brotli compression
  • Tree-shaking unused code
  • Image optimization with CDN

Lazy Loading:

vue
<script setup>
// Lazy load heavy components
const VisualCustomizer = defineAsyncComponent(() => 
  import('~/components/VisualCustomizerModal.vue')
)
</script>

Backend Performance ​

Database Indexing:

  • Primary keys on all tables
  • Foreign key indexes
  • Composite indexes for common queries
  • Covering indexes for frequent lookups

Query Optimization:

  • Avoid N+1 queries
  • Use JOIN when appropriate
  • Limit result sets
  • Cache frequent queries

Connection Pooling:

typescript
const pool = mysql.createPool({
  host: DB_HOST,
  user: DB_USER,
  password: DB_PASSWORD,
  database: DB_NAME,
  connectionLimit: 10,
  queueLimit: 0
})

Caching Strategy ​

Client-Side:

  • Pinia store for state
  • LocalStorage for preferences
  • SessionStorage for temporary data
  • Service Worker for offline support

Server-Side:

  • API response caching
  • Static asset caching
  • CDN edge caching
  • Database query result caching

API Response Times ​

Target Metrics:

  • API endpoints: < 200ms
  • Database queries: < 100ms
  • Page load time: < 2s
  • Time to interactive: < 3s

Scalability Considerations ​

Horizontal Scaling ​

Application Tier:

  • Stateless serverless functions
  • Load balancer distribution
  • Auto-scaling based on traffic
  • Multi-region deployment

Database Tier:

  • Read replicas for queries
  • Write master for updates
  • Connection pooling
  • Database sharding (if needed)

Vertical Scaling ​

Server Resources:

  • CPU: 2+ cores recommended
  • RAM: 2GB+ for application
  • Disk: SSD for database
  • Network: High bandwidth for CDN

Performance Monitoring ​

Metrics to Track:

  • Response times
  • Error rates
  • Database query performance
  • Memory usage
  • CPU utilization

Tools:

  • Built-in health check system
  • Application Performance Monitoring (APM)
  • Database query logs
  • Server resource monitoring

Monitoring & Logging ​

Health Check System ​

Endpoint: /api/health

Checks:

  • Database connectivity
  • Steam API availability
  • Disk space
  • Memory usage
  • Application status

Status Dashboard: /status page with real-time monitoring

See: Health Checks Guide

Application Logging ​

Log Levels:

  • ERROR: Critical failures
  • WARN: Important warnings
  • INFO: General information
  • DEBUG: Development debugging

Logged Events:

  • Authentication attempts
  • API errors
  • Database connection issues
  • Steam API failures
  • Performance bottlenecks

Error Tracking ​

Client-Side:

  • Console error logging
  • API error responses
  • User-friendly error messages

Server-Side:

  • Structured error logging
  • Stack trace capture
  • Error notification system
  • Database error logs

Backup & Recovery ​

Database Backups ​

Automated Backups:

  • Daily full backups
  • Point-in-time recovery
  • Offsite backup storage
  • Backup retention policy

Manual Backups:

bash
# Export database
mysqldump -u user -p database > backup.sql

# Restore database
mysql -u user -p database < backup.sql

Disaster Recovery ​

Recovery Procedures:

  1. Identify failure point
  2. Restore from latest backup
  3. Replay transaction logs
  4. Verify data integrity
  5. Resume normal operations

RTO/RPO Targets:

  • Recovery Time Objective (RTO): < 4 hours
  • Recovery Point Objective (RPO): < 1 hour
