Build Configuration

Update next.config.js for production:

module.exports = {
  // Production optimizations
  compress: true,
  poweredByHeader: false,
  reactStrictMode: true,
  
  // Security headers
  async headers() {
    return [
      {
        source: '/:path*',
        headers: [
          {
            key: 'X-DNS-Prefetch-Control',
            value: 'on'
          },
          {
            key: 'Strict-Transport-Security',
            value: 'max-age=63072000; includeSubDomains; preload'
          },
          {
            key: 'X-Frame-Options',
            value: 'SAMEORIGIN'
          },
          {
            key: 'X-Content-Type-Options',
            value: 'nosniff'
          },
          {
            key: 'X-XSS-Protection',
            value: '1; mode=block'
          },
          {
            key: 'Referrer-Policy',
            value: 'origin-when-cross-origin'
          }
        ]
      }
    ];
  }
};

Build Process

Local Build

# Build for production
pnpm build

# Test production build locally
pnpm start

Build Verification

# Check build output
ls -la .next/

# Verify no errors
# Check bundle size
# Test production build

Deployment Options

Vercel (Recommended)

Setup

1. Connect GitHub repository
2. Configure environment variables
3. Set build command: pnpm build
4. Set output directory: .next
5. Deploy

Configuration

vercel.json:

{
  "buildCommand": "pnpm build",
  "outputDirectory": ".next",
  "framework": "nextjs",
  "regions": ["iad1"]
}

Environment Variables

Set in Vercel dashboard:

• NEXT_PUBLIC_WC_PROJECT_ID
• NEXT_PUBLIC_SENTRY_DSN
• Other production variables

Other Platforms

Netlify

# netlify.toml
[build]
  command = "pnpm build"
  publish = ".next"

[[redirects]]
  from = "/*"
  to = "/index.html"
  status = 200

Docker

FROM node:18-alpine

WORKDIR /app

COPY package.json pnpm-lock.yaml ./
RUN npm install -g pnpm && pnpm install

COPY . .
RUN pnpm build

EXPOSE 3000

CMD ["pnpm", "start"]

Post-Deployment

Verification

1. Functionality Check

   • Test wallet connection
   • Test transaction creation
   • Test multi-sig approval
   • Test all features

2. Performance Check

   • Page load times
   • API response times
   • Bundle sizes
   • Lighthouse score

3. Security Check

   • HTTPS enforced
   • Security headers present
   • No console errors
   • No sensitive data exposed

Monitoring Setup

Error Tracking (Sentry)

// Initialize in app
import * as Sentry from "@sentry/nextjs";

Sentry.init({
  dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
  environment: process.env.NODE_ENV,
  tracesSampleRate: 1.0,
});

Analytics

• Set up Google Analytics
• Configure event tracking
• Monitor user behavior
• Track errors

Monitoring Checklist

• Error tracking active
• Performance monitoring active
• Uptime monitoring configured
• Alerts configured
• Dashboard setup

Rollback Procedure

Quick Rollback

1. Revert to previous deployment
2. Verify functionality
3. Check error logs
4. Notify team

Rollback Steps

# Vercel
vercel rollback

# Or redeploy previous version
git checkout previous-version
pnpm build
# Deploy

Maintenance

Regular Updates

• Dependencies: Weekly
• Security Patches: Immediately
• Feature Updates: As needed
• Performance: Monthly review

Update Process

1. Test in development
2. Run all tests
3. Security audit
4. Deploy to staging
5. Test staging
6. Deploy to production
7. Monitor closely

Backup Strategy

• Code: Git repository
• Configuration: Environment variables documented
• Data: User data in encrypted storage (client-side)

Troubleshooting

Common Issues

Build Failures

# Clear cache
rm -rf .next node_modules
pnpm install
pnpm build

Runtime Errors

1. Check error logs
2. Verify environment variables
3. Check network connectivity
4. Review recent changes

Performance Issues

1. Check bundle size
2. Review network requests
3. Analyze performance metrics
4. Optimize slow operations

Security Considerations

Production Security

• HTTPS: Always enforced
• Security Headers: Configured
• CSP: Content Security Policy
• HSTS: HTTP Strict Transport Security
• XSS Protection: Enabled

Data Protection

• Encryption: All sensitive data encrypted
• Storage: Secure storage used
• Transmission: HTTPS only
• Keys: Session-based keys

Performance Optimization

Build Optimizations

• Code splitting
• Tree shaking
• Minification
• Compression
• Image optimization

Runtime Optimizations

• Caching strategies
• Lazy loading
• Memoization
• Debouncing
• Throttling

Scaling Considerations

Horizontal Scaling

• Stateless application
• CDN for static assets
• Load balancing
• Multiple regions

Vertical Scaling

• Optimize bundle size
• Reduce memory usage
• Optimize database queries (if added)
• Cache aggressively
