|
||||
## 🎯 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

## 🎓 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;
|
||||
}
|
||||
```
