🚀 Integration Guide

1. Backend Integration

// In main.go - Add new middleware
import (
    "fotbal-club/internal/middleware"
    "fotbal-club/internal/controllers"
)

func main() {
    // ... existing setup ...
    
    // Add security middleware
    r.Use(middleware.SecurityHeaders())
    r.Use(middleware.RequestSizeLimit(10 * 1024 * 1024)) // 10MB
    r.Use(middleware.SanitizeHeaders())
    r.Use(middleware.RequestID())
    
    // Health endpoints
    healthCtrl := &controllers.HealthController{DB: dbInstance}
    r.GET("/health/live", healthCtrl.Liveness)
    r.GET("/health/ready", healthCtrl.Readiness)
    r.GET("/health", healthCtrl.Health)
    
    // Sitemap routes
    sitemapCtrl := &controllers.SitemapController{DB: dbInstance}
    r.GET("/sitemap.xml", sitemapCtrl.GetSitemap)
    r.GET("/robots.txt", sitemapCtrl.GetRobotsTxt)
    
    // CSRF protection for state-changing routes
    api.GET("/csrf-token", middleware.GetCSRFToken)
    protected := api.Group("")
    protected.Use(middleware.CSRFProtection())
    {
        // All POST/PUT/PATCH/DELETE routes
    }
}

2. Database Migration

# Run performance indexes
psql -d fotbal_club -f database/migrations/000099_performance_indexes.up.sql

3. Frontend Integration

// In frontend/src/index.tsx
import AppLazy from './App.lazy';
import { register } from './serviceWorkerRegistration';

// Use lazy-loaded app
root.render(
  <React.StrictMode>
    <ErrorBoundary>
      <HelmetProvider>
        <AppLazy />
      </HelmetProvider>
    </ErrorBoundary>
  </React.StrictMode>
);

// Register service worker for PWA
register({
  onUpdate: (registration) => {
    console.log('New version available!');
    // Optionally prompt user to update
  }
});
