## 🎯 Implementation Guide

### Step 1: Include New Files

Add to your HTML `<head>`:

```html
<link rel="stylesheet" href="/assets/css/utilities.css">
```

Add before closing `</body>`:

```html
<script src="/assets/js/utils.js"></script>
```

### Step 2: Update Existing Pages

Replace direct `localStorage` calls:

```javascript
// ❌ Before
localStorage.setItem('cart', JSON.stringify(data));

// ✅ After
storage.set('cart', data);
```

Replace `fetch` calls:

```javascript
// ❌ Before
fetch('/api/products')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));

// ✅ After
try {
  const data = await apiRequest('/api/products');
  showToast('Products loaded!', 'success');
} catch (error) {
  showToast('Failed to load products', 'error');
}
```

### Step 3: Add Accessibility Features

```html
<!-- Skip link at top of body -->
<a href="#main-content" class="skip-link">Skip to main content</a>

<!-- Main content with ID -->
<main id="main-content">...</main>

<!-- ARIA labels on icon buttons -->
<button aria-label="Close menu" onclick="closeMenu()">
  <i class="bi bi-x"></i>
</button>

<!-- Images with alt text -->
<img src="product.jpg" alt="Blue ceramic vase" loading="lazy">
```

## 🚀 Production Checklist

Before deploying to production:

### 1. Minification

```bash
# Install terser for JS minification
npm install -g terser

# Minify JavaScript
terser website/assets/js/utils.js -c -m -o website/assets/js/utils.min.js

# Minify CSS (using cssnano or similar)
npx cssnano website/assets/css/utilities.css website/assets/css/utilities.min.css
```

### 2. Update HTML References

```html
<!-- Change from -->
<script src="/assets/js/utils.js"></script>

<!-- To -->
<script src="/assets/js/utils.min.js"></script>
```

### 3. Enable Compression

In your server config (nginx/apache):

```nginx
# Enable gzip compression
gzip on;
gzip_types text/css application/javascript;
gzip_min_length 1000;
```

### 4. Cache Headers

```nginx
# Cache static assets
location ~* \.(js|css|png|jpg|jpeg|gif|svg)$ {
    expires 1y;
    add_header Cache-Control "public, immutable";
}
```

### 5. Security Headers

Already implemented in backend via Helmet ✅

## 🎓 Usage Examples

### Example 1: Show Success Message

```javascript
// After saving data
try {
  await apiRequest('/api/products', {
    method: 'POST',
    body: JSON.stringify(productData)
  });
  showToast('Product saved successfully!', 'success');
} catch (error) {
  showToast('Failed to save product', 'error');
}
```

### Example 2: Debounced Search

```javascript
// Prevent excessive API calls
const searchInput = document.getElementById('searchInput');
const debouncedSearch = debounce(async (query) => {
  const results = await apiRequest(`/api/search?q=${query}`);
  displayResults(results);
}, 500);

searchInput.addEventListener('input', (e) => {
  debouncedSearch(e.target.value);
});
```

### Example 3: Safe Storage

```javascript
// Save user preferences
function savePreferences(prefs) {
  const saved = storage.set('userPrefs', prefs);
  if (!saved) {
    showToast('Unable to save preferences', 'warning');
  }
}

// Load preferences
const prefs = storage.get('userPrefs', {
  theme: 'light',
  notifications: true
});
```

### Example 4: Accessible Images

```javascript
// Create image with fallback
const productGrid = document.getElementById('products');
products.forEach(product => {
  const img = createImage(
    product.imageurl,
    `${product.name} - ${product.category}`,
    'product-image'
  );
  productGrid.appendChild(img);
});
```

## 🐛 Known Issues & Solutions

### Issue: iOS Safari viewport height

**Problem:** 100vh includes address bar  
**Solution:** Use `dvh` units or JavaScript calculation

```css
/* Modern solution */
.full-height {
  height: 100dvh; /* dynamic viewport height */
}

/* Fallback for older browsers */
@supports not (height: 100dvh) {
  .full-height {
    height: 100vh;
  }
}
```

### Issue: LocalStorage quota exceeded

**Problem:** User has limited storage  
**Solution:** Already handled in `storage` utility

```javascript
// storage.set() returns false on quota error
if (!storage.set('largeData', data)) {
  showToast('Storage full. Please clear browser data.', 'warning');
}
```

### Issue: Focus styles on mobile Safari

**Problem:** Focus styles show on tap  
**Solution:** Already handled with `:focus-visible`

```css
/* Only shows on keyboard navigation */
button:focus-visible {
  outline: 2px solid #667eea;
}

/* Hides on mouse/touch */
button:focus:not(:focus-visible) {
  outline: none;
}
```
