## 🚀 Integration (3 Steps, 15 Minutes)
|
||||
|
||||
### Step 1: Backend Integration (5 minutes)
|
||||
|
||||
Add to `main.go`:
|
||||
|
||||
```go
|
||||
import (
|
||||
"fotbal-club/internal/middleware"
|
||||
"fotbal-club/internal/controllers"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// ... existing setup ...
|
||||
|
||||
r := gin.Default()
|
||||
|
||||
// Add security middleware (add after gin.Default())
|
||||
r.Use(middleware.SecurityHeaders())
|
||||
r.Use(middleware.SanitizeHeaders())
|
||||
r.Use(middleware.RequestID())
|
||||
r.Use(middleware.RequestSizeLimit(10 * 1024 * 1024))
|
||||
|
||||
// ... existing CORS middleware ...
|
||||
|
||||
// Add health checks
|
||||
healthCtrl := &controllers.HealthController{DB: dbInstance}
|
||||
r.GET("/health", healthCtrl.Health)
|
||||
r.GET("/health/live", healthCtrl.Liveness)
|
||||
r.GET("/health/ready", healthCtrl.Readiness)
|
||||
|
||||
// Add sitemap
|
||||
sitemapCtrl := &controllers.SitemapController{DB: dbInstance}
|
||||
r.GET("/sitemap.xml", sitemapCtrl.GetSitemap)
|
||||
r.GET("/robots.txt", sitemapCtrl.GetRobotsTxt)
|
||||
|
||||
// ... rest of setup ...
|
||||
}
|
||||
```
|
||||
|
||||
Add to `internal/routes/routes.go`:
|
||||
|
||||
```go
|
||||
func SetupRoutes(api *gin.RouterGroup, db *gorm.DB) {
|
||||
// ... existing controllers ...
|
||||
|
||||
// CSRF token endpoint
|
||||
api.GET("/csrf-token", middleware.GetCSRFToken)
|
||||
|
||||
// Protected routes with CSRF
|
||||
protected := api.Group("")
|
||||
protected.Use(middleware.CSRFProtection())
|
||||
{
|
||||
// Move all POST/PUT/PATCH/DELETE routes here
|
||||
protected.POST("/articles", baseCtrl.CreateArticle)
|
||||
protected.PUT("/articles/:id", baseCtrl.UpdateArticle)
|
||||
protected.DELETE("/articles/:id", baseCtrl.DeleteArticle)
|
||||
// ... other state-changing routes ...
|
||||
}
|
||||
|
||||
// Public GET routes (no CSRF needed)
|
||||
api.GET("/articles", baseCtrl.GetArticles)
|
||||
// ... other GET routes ...
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2: Database Optimization (5 minutes)
|
||||
|
||||
```bash
|
||||
# Backup first
|
||||
pg_dump fotbal_club > backup_$(date +%Y%m%d).sql
|
||||
|
||||
# Apply performance indexes
|
||||
psql -d fotbal_club -f database/migrations/000099_performance_indexes.up.sql
|
||||
|
||||
# Verify (should see many new indexes)
|
||||
psql -d fotbal_club -c "\di"
|
||||
```
|
||||
|
||||
### Step 3: Frontend Integration (5 minutes)
|
||||
|
||||
Update `frontend/src/index.tsx`:
|
||||
|
||||
```typescript
|
||||
// Change import
|
||||
import AppLazy from './App.lazy'; // Instead of './App'
|
||||
import { register } from './serviceWorkerRegistration';
|
||||
import { initCSRF } from './services/api';
|
||||
|
||||
// ... existing code ...
|
||||
|
||||
root.render(
|
||||
<React.StrictMode>
|
||||
<ErrorBoundary>
|
||||
<HelmetProvider>
|
||||
<ColorModeScript initialColorMode={theme.config.initialColorMode} />
|
||||
<AppLazy /> {/* Changed from <App /> */}
|
||||
</HelmetProvider>
|
||||
</ErrorBoundary>
|
||||
</React.StrictMode>
|
||||
);
|
||||
|
||||
// Initialize CSRF and Service Worker
|
||||
initCSRF();
|
||||
register({
|
||||
onUpdate: (registration) => {
|
||||
console.log('New version available!');
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
Update `frontend/src/services/api.ts` (add at the end):
|
||||
|
||||
```typescript
|
||||
// CSRF token management
|
||||
let csrfToken: string | null = null;
|
||||
|
||||
export const initCSRF = async () => {
|
||||
try {
|
||||
const response = await axios.get(`${API_URL}/csrf-token`);
|
||||
csrfToken = response.data.csrf_token;
|
||||
} catch (error) {
|
||||
console.error('Failed to fetch CSRF token:', error);
|
||||
}
|
||||
};
|
||||
|
||||
// Add to existing request interceptor
|
||||
api.interceptors.request.use(
|
||||
(config: InternalAxiosRequestConfig) => {
|
||||
// Existing auth token logic
|
||||
const token = getToken();
|
||||
if (token) {
|
||||
config.headers = config.headers || {};
|
||||
(config.headers as any).Authorization = `Bearer ${token}`;
|
||||
}
|
||||
|
||||
// Add CSRF for state-changing requests
|
||||
const method = config.method?.toLowerCase();
|
||||
if (['post', 'put', 'patch', 'delete'].includes(method || '')) {
|
||||
if (csrfToken) {
|
||||
config.headers = config.headers || {};
|
||||
(config.headers as any)['X-CSRF-Token'] = csrfToken;
|
||||
}
|
||||
}
|
||||
|
||||
return config;
|
||||
},
|
||||
(error) => Promise.reject(error)
|
||||
);
|
||||
```
|
||||
|
||||

|
||||
|
||||
## ✅ Verification (5 Minutes)

## 🔧 Optional Enhancements (15+ Minutes)
|
||||
|
||||
### Add Caching to Endpoints
|
||||
|
||||
```go
|
||||
// In your controller
|
||||
func (bc *BaseController) GetArticles(c *gin.Context) {
|
||||
cache := services.GetCacheService()
|
||||
cacheKey := "articles:published"
|
||||
|
||||
var articles []models.Article
|
||||
if err := cache.Get(cacheKey, &articles); err == nil {
|
||||
c.JSON(http.StatusOK, articles)
|
||||
return
|
||||
}
|
||||
|
||||
// Fetch from DB
|
||||
bc.DB.Where("published = ?", true).Find(&articles)
|
||||
cache.Set(cacheKey, articles, 5*time.Minute)
|
||||
c.JSON(http.StatusOK, articles)
|
||||
}
|
||||
```
|
||||
|
||||
### Add Image Optimization
|
||||
|
||||
```go
|
||||
// After saving uploaded file
|
||||
optimized, err := services.OptimizeAndResize(destPath)
|
||||
if err == nil {
|
||||
c.JSON(http.StatusOK, gin.H{
|
||||
"url": publicURL,
|
||||
"thumb": optimized.Thumb,
|
||||
"small": optimized.Small,
|
||||
"medium": optimized.Medium,
|
||||
"large": optimized.Large,
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### Add Debounced Search
|
||||
|
||||
```typescript
|
||||
import { useDebounce } from './hooks/useDebounce';
|
||||
|
||||
function SearchComponent() {
|
||||
const [query, setQuery] = useState('');
|
||||
const debouncedQuery = useDebounce(query, 500);
|
||||
|
||||
useEffect(() => {
|
||||
if (debouncedQuery) {
|
||||
// API call here
|
||||
searchArticles(debouncedQuery);
|
||||
}
|
||||
}, [debouncedQuery]);
|
||||
|
||||
return <input onChange={(e) => setQuery(e.target.value)} />;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Troubleshooting
|
||||
|
||||
### CSRF Token Issues
|
||||
```bash
|
||||
# Clear browser cache and localStorage
|
||||
# Restart backend
|
||||
# Check middleware order in main.go
|
||||
```
|
||||
|
||||
### Bundle Size Still Large
|
||||
```bash
|
||||
# Ensure using App.lazy.tsx
|
||||
# Check node_modules
|
||||
cd frontend && npm ci
|
||||
# Rebuild
|
||||
npm run build
|
||||
```
|
||||
|
||||
### Database Slow
|
||||
```bash
|
||||
# Verify indexes were created
|
||||
psql -d fotbal_club -c "\di" | grep idx_
|
||||
|
||||
# Run VACUUM
|
||||
psql -d fotbal_club -c "VACUUM ANALYZE;"
|
||||
```
|
||||
|
||||
### Service Worker Not Working
|
||||
```bash
|
||||
# Must be HTTPS or localhost
|
||||
# Check browser console for errors
|
||||
# Verify service-worker.js is accessible
|
||||
curl http://localhost:3000/service-worker.js
|
||||
```
