Deployment Workflow

# Complete automated deployment
cd engine && ./scripts/deploy-railway.sh && \
cd ../web && ./scripts/deploy-vercel.sh && \
cd .. && ./scripts/smoke-test-production.sh
Process:

  2. ✅ Sets environment variables interactively
  3. ✅ Runs pre-deployment tests and build
  4. ✅ Deploys backend using Dockerfile
  5. ✅ Verifies health endpoints
  6. ✅ Vercel script configures API URL
  7. ✅ Verifies backend connectivity
  8. ✅ Builds and deploys frontend
  9. ✅ Smoke tests validate entire stack
  10. ✅ Generates deployment report

railway logs --follow

# Vercel logs (frontend)
cd web
vercel logs --follow

​
Check Status

# Railway status
railway status

# Vercel deployments
vercel ls

​
Health Checks

# Quick health check
curl https://backend.up.railway.app/health

# Detailed readiness
curl https://backend.up.railway.app/ready

# Metrics

​
Rollback Procedures

​
Vercel Rollback (Instant)

cd web
vercel ls                                    # List deployments
vercel promote <previous-deployment-url>     # Rollback
Time: ~5 seconds

​
Railway Rollback

Via Dashboard:
  1. Open Railway project
  2. Go to Deployments tab
  3. Find previous successful deployment
  4. Click “Redeploy”
Time: ~2-3 minutes (container rebuild)

​
Emergency Rollback

If both services failing:
  1. Rollback frontend first (fastest, most visible)
  2. Then rollback backend
  3. Run smoke tests to verify
  4. Investigate issues before redeploying

​
Troubleshooting Quick Reference

​
CORS Errors

Symptom: Browser console shows CORS errors Fix: 
cd engine
railway variables set CORS_ALLOWED_ORIGINS="https://your-frontend.vercel.app"
railway up

# Verify
curl -I -H "Origin: https://your-frontend.vercel.app" \
  https://your-backend.up.railway.app/health | grep Access-Control

​
Backend Not Starting

Symptom: Health checks failing Investigate: 
railway logs | grep error
railway variables  # Verify PORT, DB_PATH
Common causes:
  • Missing environment variables
  • Database path not writable
  • Port mismatch

​
Frontend Blank Page

Symptom: White screen, no errors Investigate: 
vercel inspect <deployment-url>
vercel env ls  # Verify VITE_API_URL
Common causes:
  • Build errors (check Vercel logs)
  • Missing VITE_API_URL
  • Runtime errors (check browser console)

​
API Calls Failing

Symptom: 404 or network errors Checklist:
  1. Verify backend is running: curl https://backend/health
  2. Check VITE_API_URL: vercel env get VITE_API_URL
  3. Verify CORS: curl -I -H "Origin: ..." https://backend/api/workspace
  4. Check browser Network tab for details

​
Security Considerations

​
Secrets Management

  • ✅ Environment variables encrypted at rest
  • ✅ Never commit .env files
  • ✅ Rotate secrets periodically
  • ✅ Use Railway/Vercel secret management

​
SSL/TLS

  • ✅ Automatic SSL via Let’s Encrypt
  • ✅ All traffic HTTPS only
  • ✅ TLS 1.2+ enforced

​
CORS

  • ✅ Whitelist-based origins
  • ✅ No wildcard (*) in production
  • ✅ Credentials allowed from trusted origins

​
Rate Limiting

  • ✅ 100 requests/minute default
  • ✅ Configurable via RATE_LIMIT_REQUESTS_PER_MINUTE
  • ✅ Returns 429 when exceeded

​
Headers

Security headers configured in Vercel:
  • X-Content-Type-Options: nosniff
  • X-Frame-Options: DENY
  • X-XSS-Protection: 1; mode=block

​
Performance Metrics

​
Expected Response Times

  • Health endpoint: < 100ms
  • API endpoints: < 500ms (no workspace)
  • API endpoints: < 2000ms (with workspace operations)
  • Frontend initial load: < 2000ms
  • Frontend subsequent loads: < 500ms (cached)

​
Optimization

Backend:
  • SQLite with WAL mode
  • Request timeout: 30s
  • Concurrent request handling
Frontend:
  • Vite code splitting
  • React Query caching
  • CDN edge caching (Vercel)

​
Maintenance Tasks

​
Regular Tasks

  • Monitor logs for errors
  • Review metrics weekly
  • Update dependencies monthly
  • Rotate secrets quarterly
  • Review access logs monthly

​
Backup Strategy

Database (Railway):
  • Automatic persistent volume backups
  • Manual backup: railway run -- cat /app/data/nestr.db > backup.db
Configuration:
  • Export variables: railway variables > backup.txt
  • Commit deployment configs to git
  • Document environment setup
