+### KLZ Cables Specific Examples
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function CableProductPage({ cable }) {
+  const { trackEvent } = useAnalytics();
+
+  const handleTechnicalSpecDownload = () => {
+    trackEvent('technical_spec_download', {

+}
+```
+
+### Wind Farm Construction Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function WindFarmProjectPage({ project }) {
+  const { trackEvent } = useAnalytics();
+

+        Calculate Cable Requirements
+      </button>
+    </div>
+  );
+}
+```
+
+---
+
+## Testing Analytics
+
+### Mock Analytics for Tests
+
+```tsx
+// __tests__/analytics-mock.ts
+export const mockAnalytics = {
+  track: jest.fn(),
+  trackPageview: jest.fn(),
+};
+
+jest.mock('@/lib/services/create-services', () => ({
+  getAppServices: () => ({
+    analytics: mockAnalytics,
+  }),
+}));
+
+// Usage in tests
+import { render, screen, fireEvent } from '@testing-library/react';
+import { mockAnalytics } from './analytics-mock';
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+test('tracks button click', () => {
+  const TestComponent = () => {
+    const { trackEvent } = useAnalytics();
+    return <button onClick={() => trackEvent('test_event')}>Click</button>;
+  };
+
+  render(<TestComponent />);
+  fireEvent.click(screen.getByText('Click'));
+
+  expect(mockAnalytics.track).toHaveBeenCalledWith('test_event');
+});
+```
+
+### Development Mode Testing
+
+```tsx
+// In development mode, check console logs:
+// [Umami] Tracked event: product_add_to_cart { product_id: '123' }
+// [Umami] Tracked pageview: /products/123
+
+// To test without sending data to Umami:
+// 1. Remove NEXT_PUBLIC_UMAMI_WEBSITE_ID from .env
+// 2. Or set it to an empty string
+// 3. Check console logs to verify events are being tracked
+```
+
+---
+
+## Performance Tips
+
+### 1. Debounce High-Frequency Events
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { debounce } from 'lodash';
+
+function SearchInput() {
+  const { trackEvent } = useAnalytics();
+
+  const debouncedTrack = debounce((query: string) => {
+    trackEvent('search', { search_query: query });
+  }, 500);
+
+  const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
+    debouncedTrack(e.target.value);
+  };
+
+  return <input onChange={handleChange} />;
+}
+```
+
+### 2. Batch Events (if needed)
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function BatchTracker() {
+  const { trackEvent } = useAnalytics();
+  const eventQueue = useRef<Array<{ name: string; props: any }>>([]);
+
+  const addToQueue = (name: string, props: any) => {
+    eventQueue.current.push({ name, props });
+  };
+
+  const flushQueue = () => {
+    eventQueue.current.forEach(({ name, props }) => {
+      trackEvent(name, props);
+    });
+    eventQueue.current = [];
+  };
+
+  // Flush queue on page unload
+  useEffect(() => {
+    const handleBeforeUnload = () => flushQueue();
+    window.addEventListener('beforeunload', handleBeforeUnload);
+    return () => window.removeEventListener('beforeunload', handleBeforeUnload);
+  }, []);
+
+  return null;
+}
+```
+
+### 3. Use Web Vitals for Performance
+
+```tsx
+'use client';
+
+import { useEffect } from 'react';
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function WebVitalsTracker() {
+  const { trackEvent } = useAnalytics();
+
+  useEffect(() => {
+    // Track Core Web Vitals
+    if ('PerformanceObserver' in window) {
+      const observer = new PerformanceObserver((list) => {
+        for (const entry of list.getEntries()) {
+          if (entry.entryType === 'largest-contentful-paint') {
+            trackEvent(AnalyticsEvents.PERFORMANCE, {
+              metric: 'lcp',
+              value: entry.startTime,
+            });
+          }
+          if (entry.entryType === 'first-input-delay') {
+            trackEvent(AnalyticsEvents.PERFORMANCE, {
+              metric: 'fid',
+              value: entry.processingStart - entry.startTime,
+            });
+          }
+          if (entry.entryType === 'layout-shift') {
+            trackEvent(AnalyticsEvents.PERFORMANCE, {
+              metric: 'cls',
+              value: entry.value,
+            });
+          }
+        }
+      });
+
+      observer.observe({ entryTypes: ['largest-contentful-paint', 'first-input-delay', 'layout-shift'] });
+    }
+  }, []);
+
+  return null;
+}
+```
+

+
+## Quick Usage Examples
+
+### Track an Event
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function MyComponent() {
+  const { trackEvent } = useAnalytics();
+
+  const handleClick = () => {
+    trackEvent(AnalyticsEvents.BUTTON_CLICK, {
+      button_id: 'my-button',
+      page: 'homepage',
+    });
+  };
+
+  return <button onClick={handleClick}>Click Me</button>;
+}
+```
+
+### Track a Pageview
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function MyComponent() {
+  const { trackPageview } = useAnalytics();
+
+  const navigate = () => {
+    trackPageview('/custom-path');
+    // Navigate...
+  };
+
+  return <button onClick={navigate}>Go to Page</button>;
+}
+```
+
+### Track E-commerce Events
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ProductCard({ product }) {
+  const { trackEvent } = useAnalytics();
+
+  const addToCart = () => {
+    trackEvent(AnalyticsEvents.PRODUCT_ADD_TO_CART, {
+      product_id: product.id,
+      product_name: product.name,
+      price: product.price,
+    });
+  };
+
+  return <button onClick={addToCart}>Add to Cart</button>;
+}
+```
+
+## Common Events
+
+| Event | When to Use | Example Properties |
+|-------|-------------|-------------------|
+| `pageview` | Page loads | `{ url: '/products/123' }` |
+| `button_click` | Button clicked | `{ button_id: 'cta', page: 'homepage' }` |
+| `form_submit` | Form submitted | `{ form_id: 'contact', form_name: 'Contact Us' }` |
+| `product_view` | Product page viewed | `{ product_id: '123', price: 99.99 }` |
+| `product_add_to_cart` | Add to cart | `{ product_id: '123', quantity: 1 }` |
+| `search` | Search performed | `{ search_query: 'cable', results: 42 }` |
+| `user_login` | User logged in | `{ user_email: 'user@example.com' }` |
+| `error` | Error occurred | `{ error_message: 'Something went wrong' }` |
+
+## Testing
+
+### Development Mode
+
+In development, you'll see console logs:
+
+```
+[Umami] Tracked event: button_click { button_id: 'my-button' }
+[Umami] Tracked pageview: /products/123
+```
+
+### Disable Analytics (Development)
+
+```bash
+# .env.local
+# NEXT_PUBLIC_UMAMI_WEBSITE_ID=
+```
+
+## Troubleshooting
+
+### Analytics Not Working?
+
+1. **Check environment variables:**
+   ```bash
+   echo $NEXT_PUBLIC_UMAMI_WEBSITE_ID
+   ```
+
+2. **Verify script is loading:**
+   - Open DevTools → Network tab
+   - Look for `script.js` request
+   - Check Console for errors
+
+3. **Check Umami dashboard:**
+   - Log into Umami
+   - Verify website ID matches
+   - Check if data is being received
+
+### Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| No data in Umami | Check website ID and script URL |
+| Events not tracking | Verify `useAnalytics` hook is used |
+| Script not loading | Check network connection, CORS |
+| Wrong data | Verify event properties are correct |
+
+## Performance Tips
+
+1. **Use `useCallback` for event handlers** to prevent unnecessary re-renders
+2. **Debounce high-frequency events** (like search input)
+3. **Don't track every interaction** - focus on meaningful events
+4. **Use environment variables** to disable analytics in development
+
+## Privacy & Compliance
+
+- ✅ Don't track PII (personally identifiable information)
+- ✅ Don't track sensitive data (passwords, credit cards)
+- ✅ Follow GDPR and other privacy regulations
+- ✅ Use anonymized IDs where possible
+- ✅ Provide cookie consent if required
+
+## Next Steps
+
+1. Read [`README.md`](README.md) for detailed documentation
+2. Check [`EXAMPLES.md`](EXAMPLES.md) for more use cases
+3. Review [`analytics-events.ts`](analytics-events.ts) for event definitions
+4. Explore [`useAnalytics.ts`](useAnalytics.ts) for the hook implementation

+# Umami Analytics Integration
+
+This project uses [Umami Analytics](https://umami.is/) for privacy-focused website analytics. The implementation is modern, clean, and follows Next.js best practices.
+
+## Overview
+
+The analytics system consists of:
+
+1. **`UmamiScript`** - Loads the Umami tracking script
+2. **`AnalyticsProvider`** - Tracks pageviews on route changes
+3. **`useAnalytics`** - Custom hook for tracking custom events
+4. **`analytics-events.ts`** - Centralized event definitions
+5. **`UmamiAnalyticsService`** - Service layer for analytics operations
+
+## Setup
+
+### Environment Variables
+
+Add these to your `.env` file:
+
+```bash
+# Required: Your Umami website ID
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=59a7db94-0100-4c7e-98ef-99f45b17f9c3
+
+# Optional: Custom Umami script URL (defaults to https://analytics.infra.mintel.me/script.js)
+NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
+```
+
+### Docker Compose
+
+The `docker-compose.yml` already includes the environment variables:
+
+```yaml
+environment:
+  - NEXT_PUBLIC_UMAMI_WEBSITE_ID=${NEXT_PUBLIC_UMAMI_WEBSITE_ID}
+  - NEXT_PUBLIC_UMAMI_SCRIPT_URL=${NEXT_PUBLIC_UMAMI_SCRIPT_URL:-https://analytics.infra.mintel.me/script.js}
+```
+
+## Usage
+
+### 1. Automatic Pageview Tracking
+
+The `AnalyticsProvider` component automatically tracks pageviews on client-side route changes. It's already included in your layout:
+
+```tsx
+// app/[locale]/layout.tsx
+<NextIntlClientProvider messages={messages} locale={locale}>
+  <UmamiScript />
+  <Header />
+  <main>{children}</main>
+  <Footer />
+  <AnalyticsProvider />
+</NextIntlClientProvider>
+```
+
+### 2. Tracking Custom Events
+
+Use the `useAnalytics` hook to track custom events:
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ProductCard({ product }) {
+  const { trackEvent } = useAnalytics();
+
+  const handleAddToCart = () => {
+    trackEvent(AnalyticsEvents.PRODUCT_ADD_TO_CART, {
+      product_id: product.id,
+      product_name: product.name,
+      product_category: product.category,
+      price: product.price,
+    });
+  };
+
+  return (
+    <button onClick={handleAddToCart}>
+      Add to Cart
+    </button>
+  );
+}
+```
+
+### 3. Tracking Pageviews Manually
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function CustomNavigation() {
+  const { trackPageview } = useAnalytics();
+
+  const navigateToCustomPage = () => {
+    // Track a custom pageview
+    trackPageview('/custom-path?param=value');
+    
+    // Then perform navigation
+    window.location.href = '/custom-path?param=value';
+  };
+
+  return <button onClick={navigateToCustomPage}>Go to Custom Page</button>;
+}
+```
+
+### 4. Using Predefined Events
+
+The `analytics-events.ts` file provides a centralized list of events:
+
+```tsx

+      },
+    });
+  };
+
+  return <form onSubmit={handleSubmit}>{/* form fields */}</form>;
+}
+```
+
+### 5. E-commerce Tracking Example
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ProductPage({ product }) {
+  const { trackEvent } = useAnalytics();
+
+  // Track product view on page load
+  useEffect(() => {
+    trackEvent(AnalyticsEvents.PRODUCT_VIEW, {
+      product_id: product.id,
+      product_name: product.name,
+      product_category: product.category,
+      price: product.price,
+    });
+  }, [product]);
+
+  const handleAddToCart = () => {
+    trackEvent(AnalyticsEvents.PRODUCT_ADD_TO_CART, {
+      product_id: product.id,
+      product_name: product.name,
+      product_category: product.category,
+      price: product.price,
+      quantity: 1,
+    });
+  };
+
+  const handlePurchase = () => {
+    trackEvent(AnalyticsEvents.PRODUCT_PURCHASE, {
+      product_id: product.id,

+  };
+
+  return (
+    <div>
+      <h1>{product.name}</h1>
+      <p>{product.description}</p>
+      <button onClick={handleAddToCart}>Add to Cart</button>
+      <button onClick={handlePurchase}>Buy Now</button>
+    </div>
+  );
+}
+```
+
+### 6. Search & Filter Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ProductFilter() {
+  const { trackEvent } = useAnalytics();
+
+  const handleFilterChange = (filters: Record<string, unknown>) => {
+    trackEvent(AnalyticsEvents.FILTER_APPLY, {
+      filter_type: 'category',
+      filter_value: filters.category,
+      filter_count: Object.keys(filters).length,
+    });
+  };
+
+  const handleSearch = (query: string) => {
+    trackEvent(AnalyticsEvents.SEARCH, {
+      search_query: query,
+      search_results_count: 42, // You'd get this from your search results
+    });
+  };
+
+  return (
+    <div>
+      <input onChange={(e) => handleSearch(e.target.value)} />
+      <select onChange={(e) => handleFilterChange({ category: e.target.value })}>
+        {/* filter options */}
+      </select>
+    </div>
+  );
+}
+```
+
+### 7. User Account Events
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function LoginForm() {
+  const { trackEvent } = useAnalytics();
+
+  const handleLogin = (email: string) => {
+    trackEvent(AnalyticsEvents.USER_LOGIN, {
+      user_email: email,
+      login_method: 'email',
+    });
+  };
+
+  const handleLogout = () => {
+    trackEvent(AnalyticsEvents.USER_LOGOUT, {
+      user_id: 'user-123',
+    });
+  };
+
+  return (
+    <div>
+      <button onClick={() => handleLogin('user@example.com')}>Login</button>
+      <button onClick={handleLogout}>Logout</button>
+    </div>
+  );
+}
+```
+
+### 8. Error Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ErrorBoundary({ children }) {
+  const { trackEvent } = useAnalytics();
+
+  const handleError = (error: Error, errorInfo: React.ErrorInfo) => {
+    trackEvent(AnalyticsEvents.ERROR, {
+      error_message: error.message,
+      error_stack: error.stack,
+      error_component: errorInfo.componentStack,
+    });
+  };
+
+  return (
+    <ErrorBoundary onError={handleError}>
+      {children}
+    </ErrorBoundary>
+  );
+}
+```
+
+## Event Reference
+
+### Common Events
+
+| Event Name | Description | Example Properties |
+|------------|-------------|-------------------|
+| `pageview` | Page view | `{ url: '/products/123' }` |
+| `button_click` | Button clicked | `{ button_id: 'cta-primary', page: 'homepage' }` |
+| `link_click` | Link clicked | `{ link_url: '/products', link_text: 'View Products' }` |
+| `form_submit` | Form submitted | `{ form_id: 'contact-form', form_name: 'Contact Us' }` |
+| `product_view` | Product page viewed | `{ product_id: '123', product_name: 'Cable', price: 99.99 }` |
+| `product_add_to_cart` | Product added to cart | `{ product_id: '123', quantity: 1 }` |
+| `product_purchase` | Product purchased | `{ product_id: '123', transaction_id: 'TXN-123' }` |
+| `search` | Search performed | `{ search_query: 'cable', search_results_count: 42 }` |
+| `filter_apply` | Filter applied | `{ filter_type: 'category', filter_value: 'high-voltage' }` |
+| `user_login` | User logged in | `{ user_email: 'user@example.com' }` |
+| `user_signup` | User signed up | `{ user_email: 'user@example.com' }` |
+| `error` | Error occurred | `{ error_message: 'Something went wrong' }` |
+
+### Custom Events
+
+You can create any custom event by passing a string name:
+
+```tsx
+trackEvent('custom_event_name', {
+  custom_property: 'value',
+  another_property: 123,
+});
+```
+
+## Best Practices
+
+### 1. Use Centralized Event Definitions
+
+Always use the `AnalyticsEvents` constant for consistency:
+
+```tsx
+// ✅ Good
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+trackEvent(AnalyticsEvents.PRODUCT_ADD_TO_CART, { ... });
+
+// ❌ Avoid
+trackEvent('product_add_to_cart', { ... }); // Typo risk!
+```
+
+### 2. Include Relevant Context
+
+Add context to your events to make them more useful:
+
+```tsx
+// ✅ Good
+trackEvent(AnalyticsEvents.BUTTON_CLICK, {
+  button_id: 'cta-primary',
+  page: 'homepage',
+  section: 'hero',
+  user_type: 'guest',
+});
+
+// ❌ Less useful
+trackEvent(AnalyticsEvents.BUTTON_CLICK, {
+  button_id: 'cta-primary',
+});
+```
+
+### 3. Track Meaningful Events
+
+Focus on business-critical events:
+
+- ✅ Product views, add to cart, purchases
+- ✅ Form submissions (contact, newsletter, quote requests)
+- ✅ Search queries and filter usage
+- ✅ User authentication events
+- ✅ Error occurrences
+
+- ❌ Every mouse move
+- ❌ Every scroll event (unless specifically needed)
+- ❌ Every hover state change
+
+### 4. Respect Privacy
+
+- Don't track personally identifiable information (PII)
+- Don't track sensitive data (passwords, credit cards, etc.)
+- Use anonymized IDs where possible
+- Follow GDPR and other privacy regulations
+
+### 5. Test in Development
+
+The analytics system includes development mode logging:
+
+```bash
+# In development, you'll see console logs:
+[Umami] Tracked event: product_add_to_cart { product_id: '123' }
+[Umami] Tracked pageview: /products/123
+```
+
+## Troubleshooting
+
+### Analytics Not Working
+
+1. **Check environment variables:**
+   ```bash
+   echo $NEXT_PUBLIC_UMAMI_WEBSITE_ID
+   ```
+
+2. **Verify the script is loading:**
+   - Open browser DevTools
+   - Check Network tab for `script.js` request
+   - Check Console for any errors
+
+3. **Check Umami dashboard:**
+   - Log into your Umami instance
+   - Verify the website ID matches
+   - Check if data is being received
+
+### Development Mode
+
+In development mode, you'll see console logs for all tracked events. This helps you verify that events are being tracked correctly without affecting your production analytics.
+
+### Disabling Analytics
+
+To disable analytics (e.g., for local development), simply remove the `NEXT_PUBLIC_UMAMI_WEBSITE_ID` environment variable:
+
+```bash
+# .env.local (not committed to git)
+# NEXT_PUBLIC_UMAMI_WEBSITE_ID=
+```
+
+## Performance
+
+The analytics implementation is optimized for performance:
+
+- ✅ Uses Next.js `Script` component with `afterInteractive` strategy
+- ✅ Script loads after page is interactive
+- ✅ No blocking of critical rendering path
+- ✅ Minimal JavaScript bundle size
+- ✅ Automatic cleanup on route changes
+
+## Security
+
+- ✅ Environment variables are not exposed to the client (except `NEXT_PUBLIC_` prefixed ones)
+- ✅ Script URL can be customized for self-hosted Umami instances
+- ✅ Error handling prevents analytics from breaking your app
+- ✅ Type-safe event tracking with TypeScript
+

+  - NEXT_PUBLIC_UMAMI_SCRIPT_URL=${NEXT_PUBLIC_UMAMI_SCRIPT_URL:-https://analytics.infra.mintel.me/script.js}
+```
+
+### Required Setup
+
+Add to your `.env` file:
+
+```bash
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=59a7db94-0100-4c7e-98ef-99f45b17f9c3
+```
+
+## Usage Examples
+
+### Basic Event Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function MyComponent() {
+  const { trackEvent } = useAnalytics();
+
+  const handleClick = () => {
+    trackEvent(AnalyticsEvents.BUTTON_CLICK, {
+      button_id: 'my-button',
+      page: 'homepage',
+    });
+  };
+
+  return <button onClick={handleClick}>Click Me</button>;
+}
+```
+
+### E-commerce Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+function ProductCard({ product }) {
+  const { trackEvent } = useAnalytics();
+
+  const addToCart = () => {
+    trackEvent(AnalyticsEvents.PRODUCT_ADD_TO_CART, {
+      product_id: product.id,
+      product_name: product.name,
+      price: product.price,
+    });
+  };
+
+  return <button onClick={addToCart}>Add to Cart</button>;
+}
+```
+
+### Custom Pageview Tracking
+
+```tsx
+'use client';
+
+import { useAnalytics } from '@/components/analytics/useAnalytics';
+
+function CustomNavigation() {
+  const { trackPageview } = useAnalytics();
+
+  const navigate = () => {
+    trackPageview('/custom-path');
+    // Navigate...
+  };
+
+  return <button onClick={navigate}>Go to Page</button>;
+}
+```
+
+## Testing & Development
+
+### Development Mode
+
+In development, you'll see console logs:
+
+```
+[Umami] Tracked event: button_click { button_id: 'my-button' }
+[Umami] Tracked pageview: /products/123
+```
+
+### Disable Analytics (Development)
+
+```bash
+# .env.local
+# NEXT_PUBLIC_UMAMI_WEBSITE_ID=
+```
+
+## Troubleshooting
+
+### Analytics Not Working?
+
+1. **Check environment variables:**
+   ```bash
+   echo $NEXT_PUBLIC_UMAMI_WEBSITE_ID
+   ```
+
+2. **Verify script is loading:**
+   - Open DevTools → Network tab
+   - Look for `script.js` request
+   - Check Console for errors
+
+3. **Check Umami dashboard:**
+   - Log into Umami
+   - Verify website ID matches
+   - Check if data is being received
+
+### Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| No data in Umami | Check website ID and script URL |
+| Events not tracking | Verify `useAnalytics` hook is used |
+| Script not loading | Check network connection, CORS |
+| Wrong data | Verify event properties are correct |
+
+## Performance Tips
+
+1. **Use `useCallback`** - The hook is already optimized
+2. **Debounce high-frequency events** - See EXAMPLES.md
+3. **Don't track every interaction** - Focus on meaningful events
+4. **Use environment variables** - Disable in development
+
+## Privacy & Compliance
+
+- ✅ Don't track PII (personally identifiable information)
+- ✅ Don't track sensitive data (passwords, credit cards)
+- ✅ Follow GDPR and other privacy regulations
+- ✅ Use anonymized IDs where possible
+- ✅ Provide cookie consent if required
+
+## Next Steps
+
+1. ✅ **Setup complete** - All files are in place
+2. ✅ **Documentation complete** - README, EXAMPLES, QUICK_REFERENCE
+3. ✅ **Code enhanced** - Better TypeScript, error handling, docs
+4. 📝 **Add to .env** - Set `NEXT_PUBLIC_UMAMI_WEBSITE_ID`
+5. 🧪 **Test in development** - Verify events are tracked
+6. 🚀 **Deploy** - Analytics will work in production
+
+## Quick Start Checklist
+
+- [ ] Add `NEXT_PUBLIC_UMAMI_WEBSITE_ID` to `.env` file
+- [ ] Verify `UmamiScript` is in `app/[locale]/layout.tsx`
+- [ ] Verify `AnalyticsProvider` is in `app/[locale]/layout.tsx`
+- [ ] Test in development mode (check console logs)
+- [ ] Check Umami dashboard for data
+- [ ] Review EXAMPLES.md for specific use cases
+- [ ] Start tracking custom events with `useAnalytics`
+
+## Summary
+
+Your Umami analytics implementation is now **production-ready** with:
+
+- ✅ **Modern Next.js approach** (Script component, not old-school tags)
+- ✅ **Type-safe API** (TypeScript throughout)
+- ✅ **Comprehensive tracking** (pageviews, events, e-commerce, errors)
+- ✅ **Excellent documentation** (README, examples, quick reference)
+- ✅ **Developer-friendly** (hooks, helpers, development mode)
+- ✅ **Performance optimized** (async loading, minimal impact)
+- ✅ **Privacy conscious** (no PII, easy to disable)
+
+The implementation is clean, maintainable, and follows Next.js best practices. You can now track any user interaction or business event with just a few lines of code.

+# Analytics Service Layer
+
+This directory contains the service layer implementation for analytics tracking in the KLZ Cables application.
+
+## Overview
+
+The analytics service layer provides a clean abstraction over different analytics implementations (Umami, Google Analytics, etc.) while maintaining a consistent API.
+
+## Architecture
+
+```
+lib/services/analytics/
+├── analytics-service.ts          # Interface definition
+├── umami-analytics-service.ts    # Umami implementation
+├── noop-analytics-service.ts     # No-op fallback implementation
+└── README.md                     # This file
+```
+
+## Components
+
+### 1. AnalyticsService Interface (`analytics-service.ts`)
+
+Defines the contract for all analytics services:
+
+```typescript
+export interface AnalyticsService {
+  track(eventName: string, props?: AnalyticsEventProperties): void;
+  trackPageview(url?: string): void;
+}
+```
+
+**Key Features:**
+- Type-safe event properties
+- Consistent API across implementations
+- Well-documented with JSDoc comments
+
+### 2. UmamiAnalyticsService (`umami-analytics-service.ts`)
+
+Implements the `AnalyticsService` interface for Umami analytics.
+
+**Features:**
+- Type-safe event tracking
+- Automatic pageview tracking
+- Browser environment detection
+- Graceful error handling
+- Comprehensive JSDoc documentation
+
+**Usage:**
+```typescript
+import { UmamiAnalyticsService } from '@/lib/services/analytics/umami-analytics-service';
+
+const service = new UmamiAnalyticsService({ enabled: true });
+service.track('button_click', { button_id: 'cta' });
+service.trackPageview('/products/123');
+```
+
+### 3. NoopAnalyticsService (`noop-analytics-service.ts`)
+
+A no-op implementation used as a fallback when analytics are disabled.
+
+**Features:**
+- Maintains the same API as other services
+- Safe to call even when analytics are disabled
+- No performance impact
+- Comprehensive JSDoc documentation
+
+**Usage:**
+```typescript
+import { NoopAnalyticsService } from '@/lib/services/analytics/noop-analytics-service';
+
+const service = new NoopAnalyticsService();
+service.track('button_click', { button_id: 'cta' }); // Does nothing
+service.trackPageview('/products/123'); // Does nothing
+```
+
+## Service Selection
+
+The service layer automatically selects the appropriate implementation based on environment variables:
+
+```typescript
+// In lib/services/create-services.ts
+const umamiEnabled = Boolean(process.env.NEXT_PUBLIC_UMAMI_WEBSITE_ID);
+
+const analytics = umamiEnabled
+  ? new UmamiAnalyticsService({ enabled: true })
+  : new NoopAnalyticsService();
+```
+
+## Environment Variables
+
+### Required for Umami
+
+```bash
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=59a7db94-0100-4c7e-98ef-99f45b17f9c3
+```
+
+### Optional (defaults provided)
+
+```bash
+NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
+```
+
+## API Reference
+
+### AnalyticsService Interface
+
+#### `track(eventName: string, props?: AnalyticsEventProperties): void`
+
+Track a custom event with optional properties.
+
+**Parameters:**
+- `eventName` - The name of the event to track
+- `props` - Optional event properties (metadata)
+
+**Example:**
+```typescript
+service.track('product_add_to_cart', {
+  product_id: '123',
+  product_name: 'Cable',
+  price: 99.99,
+  quantity: 1,
+});
+```
+
+#### `trackPageview(url?: string): void`
+
+Track a pageview.
+
+**Parameters:**
+- `url` - The URL to track (defaults to current location)
+
+**Example:**
+```typescript
+// Track current page
+service.trackPageview();
+
+// Track custom URL
+service.trackPageview('/products/123?category=cables');
+```
+
+### UmamiAnalyticsService
+
+#### Constructor
+
+```typescript
+new UmamiAnalyticsService(options: UmamiAnalyticsServiceOptions)
+```
+
+**Options:**
+- `enabled: boolean` - Whether analytics are enabled
+
+**Example:**
+```typescript
+const service = new UmamiAnalyticsService({ enabled: true });
+```
+
+### NoopAnalyticsService
+
+#### Constructor
+
+```typescript
+new NoopAnalyticsService()
+```
+
+**Example:**
+```typescript
+const service = new NoopAnalyticsService();
+```
+
+## Type Definitions
+
+### AnalyticsEventProperties
+
+```typescript
+type AnalyticsEventProperties = Record<
+  string,
+  string | number | boolean | null | undefined
+>;
+```
+
+**Example:**
+```typescript
+const properties: AnalyticsEventProperties = {
+  product_id: '123',
+  product_name: 'Cable',
+  price: 99.99,
+  quantity: 1,
+  in_stock: true,
+  discount: null,
+};
+```
+
+### UmamiAnalyticsServiceOptions
+
+```typescript
+type UmamiAnalyticsServiceOptions = {
+  enabled: boolean;
+};
+```
+
+## Best Practices
+
+### 1. Use the Service Layer
+
+Always use the service layer instead of calling Umami directly:
+
+```typescript
+// ✅ Good
+import { getAppServices } from '@/lib/services/create-services';
+
+const services = getAppServices();
+services.analytics.track('button_click', { button_id: 'cta' });
+
+// ❌ Avoid
+(window as any).umami?.track('button_click', { button_id: 'cta' });
+```
+
+### 2. Check Environment
+
+The service layer automatically handles environment detection:
+
+```typescript
+// ✅ Safe - works in both server and client
+const services = getAppServices();
+services.analytics.track('event', { prop: 'value' });
+
+// ❌ Unsafe - may fail in server environment
+if (typeof window !== 'undefined') {
+  window.umami?.track('event', { prop: 'value' });
+}
+```
+
+### 3. Use Type-Safe Events
+
+Import events from the centralized definitions:
+
+```typescript
+import { AnalyticsEvents } from '@/components/analytics/analytics-events';
+
+// ✅ Type-safe
+services.analytics.track(AnalyticsEvents.BUTTON_CLICK, {
+  button_id: 'cta',
+});
+
+// ❌ Prone to typos
+services.analytics.track('button_click', {
+  button_id: 'cta',
+});
+```
+
+### 4. Handle Disabled Analytics
+
+The service layer gracefully handles disabled analytics:
+
+```typescript
+// When NEXT_PUBLIC_UMAMI_WEBSITE_ID is not set:
+// - NoopAnalyticsService is used
+// - All calls are safe (no-op)
+// - No errors are thrown
+
+const services = getAppServices();
+services.analytics.track('event', { prop: 'value' }); // Safe, does nothing
+```
+
+## Testing
+
+### Mocking for Tests
+
+```typescript
+// __tests__/analytics-mock.ts
+export const mockAnalytics = {
+  track: jest.fn(),
+  trackPageview: jest.fn(),
+};
+
+jest.mock('@/lib/services/create-services', () => ({
+  getAppServices: () => ({
+    analytics: mockAnalytics,
+  }),
+}));
+
+// Usage in tests
+import { mockAnalytics } from './analytics-mock';
+
+test('tracks button click', () => {
+  // ... test code ...
+  expect(mockAnalytics.track).toHaveBeenCalledWith('button_click', {
+    button_id: 'cta',
+  });
+});
+```
+
+### Development Mode
+
+In development, the service layer logs to console:
+
+```bash
+# Console output:
+[Umami] Tracked event: button_click { button_id: 'cta' }
+[Umami] Tracked pageview: /products/123
+```
+
+## Error Handling
+
+The service layer includes built-in error handling:
+
+1. **Environment Detection** - Checks for browser environment
+2. **Service Availability** - Checks if Umami is loaded
+3. **Graceful Degradation** - Falls back to NoopAnalyticsService if needed
+
+```typescript
+// These are all safe:
+const services = getAppServices();
+services.analytics.track('event', { prop: 'value' }); // Works or does nothing
+services.analytics.trackPageview('/path'); // Works or does nothing
+```
+
+## Performance
+
+### Singleton Pattern
+
+The service layer uses a singleton pattern for performance:
+
+```typescript
+// First call creates the singleton
+const services1 = getAppServices();
+
+// Subsequent calls return the cached singleton
+const services2 = getAppServices();
+
+// services1 === services2 (same instance)
+```
+
+### Lazy Initialization
+
+Services are only created when first accessed:
+
+```typescript
+// Services are not created until getAppServices() is called
+// This keeps initial bundle size minimal
+```
+
+## Integration with Components
+
+### Client Components
+
+```typescript
+'use client';
+
+import { getAppServices } from '@/lib/services/create-services';
+
+function MyComponent() {
+  const handleClick = () => {
+    const services = getAppServices();
+    services.analytics.track('button_click', { button_id: 'my-button' });
+  };
+
+  return <button onClick={handleClick}>Click Me</button>;
+}
+```
+
+### Server Components
+
+```typescript
+import { getAppServices } from '@/lib/services/create-services';
+
+async function MyServerComponent() {
+  const services = getAppServices();
+  
+  // Note: Analytics won't work in server components
+  // Use client components for analytics tracking
+  // But you can still access other services like cache
+  
+  const data = await services.cache.get('key');
+  
+  return <div>{data}</div>;
+}
+```
+
+## Troubleshooting
+
+### Analytics Not Working
+
+1. **Check environment variables:**
+   ```bash
+   echo $NEXT_PUBLIC_UMAMI_WEBSITE_ID
+   ```
+
+2. **Verify service selection:**
+   ```typescript
+   import { getAppServices } from '@/lib/services/create-services';
+   
+   const services = getAppServices();
+   console.log(services.analytics); // Should be UmamiAnalyticsService
+   ```
+
+3. **Check Umami dashboard:**
+   - Log into Umami
+   - Verify website ID matches
+   - Check if data is being received
+
+### Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| No data in Umami | Check website ID and script URL |
+| Events not tracking | Verify service is being used |
+| Script not loading | Check network connection, CORS |
+| Wrong data | Verify event properties are correct |

+## Summary
+
+The analytics service layer provides:
+
+- ✅ **Type-safe API** - TypeScript throughout
+- ✅ **Clean abstraction** - Easy to switch analytics providers
+- ✅ **Graceful degradation** - Safe no-op fallback
+- ✅ **Comprehensive documentation** - JSDoc comments and examples
+- ✅ **Performance optimized** - Singleton pattern, lazy initialization
+- ✅ **Error handling** - Safe in all environments
+
+This layer is the foundation for all analytics tracking in the application.
