🚀 Quick Start Guide - SkyArtShop

After Code Review Implementation

All security issues have been fixed. The application is now production-ready.

✅ What Was Fixed

Security (CRITICAL)

✅ Removed hardcoded credentials → .env file
✅ Added input validation → express-validator
✅ Implemented rate limiting → Prevent brute force
✅ Added security headers → Helmet.js
✅ SQL injection protection → Parameterized queries
✅ Enhanced file upload security → Type/size validation

Production Ready

✅ Proper logging → Winston with rotation
✅ Error handling → Centralized handler
✅ Database transactions → Data consistency
✅ Graceful shutdown → No data loss
✅ Health check → Real DB connectivity test
✅ Security audit → 0 vulnerabilities

🔧 Immediate Actions Required

1. Session Secret (DONE ✓)

The SESSION_SECRET has been updated with a cryptographically secure value.

2. Database Password

Update your database password in .env:

nano .env
# Update DB_PASSWORD with your actual password

3. Restart Server

pm2 restart skyartshop
pm2 save

4. Verify Server

# Check health
curl http://localhost:5000/health

# Should return:
# {"status":"ok","timestamp":"...","uptime":...,"database":{...}}

📊 Server Status

Check Logs

# Winston logs (NEW)
tail -f backend/logs/combined.log
tail -f backend/logs/error.log

# PM2 logs
pm2 logs skyartshop

# PM2 monitor
pm2 monit

Test Endpoints

# Health check
curl http://localhost:5000/health

# Test rate limiting (should block after 5 attempts)
for i in {1..6}; do
  curl -X POST http://localhost:5000/api/admin/login \
    -H "Content-Type: application/json" \
    -d '{"email":"test@test.com","password":"wrong"}'
  echo ""
done

🐛 Troubleshooting

Server Won't Start

# Check logs
pm2 logs skyartshop

# Check syntax
cd backend
node -c server.js

# Check database connection
psql -h localhost -U skyartapp -d skyartshop -c "SELECT 1;"

Database Connection Error

# Verify credentials in .env
cat .env | grep DB_

# Test connection
psql -h $DB_HOST -U $DB_USER -d $DB_NAME

Rate Limit Issues

# Wait 15 minutes or restart server
pm2 restart skyartshop

Log Files Too Large

# Logs auto-rotate at 10MB
# Check current size
du -h backend/logs/

# Manual cleanup if needed
> backend/logs/combined.log
> backend/logs/error.log

📈 Monitoring

Watch for These Events

Failed Logins

grep "invalid password" backend/logs/combined.log

Rate Limit Violations

grep "Rate limit exceeded" backend/logs/combined.log

Database Errors

grep "PostgreSQL error" backend/logs/error.log

Upload Rejections

grep "File upload rejected" backend/logs/combined.log

🔄 Common Tasks

Update Code

git pull
cd backend
npm install
pm2 restart skyartshop

Database Backup

pg_dump -h localhost -U skyartapp skyartshop > backup_$(date +%Y%m%d).sql

Rotate Logs Manually

cd backend/logs
tar -czf logs_$(date +%Y%m%d).tar.gz *.log
> combined.log
> error.log

Check Security Audit

cd backend
npm audit

🚨 Emergency Procedures
