|
||||
```

|
||||
```
|
||||
|
||||
## Alpine.js Components
|
||||
|
||||
### Theme Toggle
|
||||
|
||||
**Usage**:
|
||||
```html
|
||||
<div x-data="themeToggle()">
|
||||
<button @click="toggleTheme()">Toggle Theme</button>

||||
|
||||
**Features**:
|
||||
- Cycles through light → dark → system
|
||||
- Persists preference in localStorage
|
||||
- Responds to system theme changes
|
||||
|
||||
### Search Component
|
||||
|
||||
**Usage**:
|
||||
```html
|
||||
<div x-data="searchComponent()">
|
||||
<input x-model="query" @input.debounce.300ms="search()" />
|
||||
<div x-show="results.length > 0">
|
||||
<template x-for="result in results">
|
||||
<div x-text="result.title"></div>
|
||||
</template>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Modal Component
|
||||
|
||||
**Usage**:
|
||||
```html
|
||||
<div x-data="modal()">
|
||||
<button @click="show()">Open Modal</button>

||||
<div x-show="open" x-transition class="modal-overlay">
|
||||
<div class="modal-content">
|
||||
<h2>Modal Title</h2>
|
||||
<button @click="hide()">Close</button>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Form Component
|
||||
|
||||
**Usage**:
|
||||
```html
|
||||
<div x-data="form({ name: '', email: '' })">
|
||||
<input x-model="data.name" @input="setField('name', $event.target.value)" />
|
||||
<div x-show="hasError('name')" x-text="getError('name')"></div>
|
||||
<button @click="submit('/api/submit/')">Submit</button>
|
||||
</div>
|
||||
```
|
||||
|
||||
## HTMX Patterns
|
||||
|
||||
### Lazy Loading
|
||||
|
||||
```html
|
||||
<div hx-get="/api/content/" hx-trigger="intersect" hx-swap="innerHTML">
|
||||
Loading...
|
||||
</div>
|
||||
```
|
||||
|
||||
### Live Search
|
||||
|
||||
```html
|
||||
<input hx-get="/api/search/"
|
||||
hx-trigger="input changed delay:300ms"
|
||||
hx-target="#results"
|
||||
hx-include="this"
|
||||
name="q" />
|
||||
<div id="results"></div>
|
||||
```
|
||||
|
||||
### Infinite Scroll
|
||||
|
||||
```html
|
||||
<div hx-get="/api/more/?page=2"
|
||||
hx-trigger="revealed"
|
||||
hx-swap="beforeend"
|
||||
hx-target="#content">
|
||||
Load more...
|
||||
</div>
|
||||
```
|
||||
|
||||
### Form Submission
|
||||
|
||||
```html
|
||||
<form hx-post="/api/submit/"
|
||||
hx-target="#form-container"
|
||||
hx-swap="outerHTML">
|
||||
{% csrf_token %}
|
||||
<!-- form fields -->
|
||||
<button type="submit">Submit</button>
|
||||
</form>
|
||||
```
|
||||
|
||||
## Design System
|
||||
|
||||
### CSS Variables
|
||||
|
||||
The design system uses CSS custom properties for consistent theming:
|
||||
|
||||
```css
|
||||
:root {
|
||||
--background: 0 0% 100%;
|
||||
--foreground: 222.2 84% 4.9%;
|
||||
--primary: 262.1 83.3% 57.8%;
|
||||
--secondary: 210 40% 96%;
|
||||
--muted: 210 40% 96%;
|
||||
--accent: 210 40% 96%;
|
||||
--destructive: 0 84.2% 60.2%;
|
||||
--border: 214.3 31.8% 91.4%;
|
||||
--input: 214.3 31.8% 91.4%;
|
||||
--ring: 262.1 83.3% 57.8%;
|
||||
}
|
||||
```
|
||||
|
||||
### Utility Classes
|
||||
|
||||
```css
|
||||
.bg-primary { background-color: hsl(var(--primary)); }
|
||||
.text-primary { color: hsl(var(--primary)); }
|
||||
.border-primary { border-color: hsl(var(--primary)); }
|
||||
```
|
||||
|
||||
### Component Classes
|
||||
|
||||
```css
|
||||
.btn { /* Base button styles */ }
|
||||
.btn-default { /* Primary button variant */ }
|
||||
.card { /* Base card styles */ }
|
||||
.input { /* Base input styles */ }
|
||||
```
|
||||
|
||||
## Django Integration
|
||||
|
||||
### View Enhancements
|
||||
|
||||
```python
|
||||
def enhanced_view(request):
|
||||
if request.headers.get('HX-Request'):
|
||||
# Return partial template for HTMX
|
||||
return render(request, 'partials/content.html', context)
|
||||
# Return full page
|
||||
return render(request, 'full_page.html', context)
|
||||
```
|
||||
|
||||
### Template Structure
|
||||
|
||||
```
|
||||
backend/templates/
|
||||
├── base/
|
||||
│ └── base.html (enhanced with new header)
|
||||
├── components/
|
||||
│ ├── ui/
|
||||
│ │ ├── button.html
|
||||
│ │ ├── card.html
|
||||
│ │ └── input.html
|
||||
│ └── layout/
|
||||
│ └── enhanced_header.html
|
||||
└── partials/
|
||||

## Testing Strategy
|
||||
|
||||
### Manual Testing Checklist
|
||||
|
||||
- [ ] Header navigation works on all screen sizes
|
||||
- [ ] Browse menu opens and closes properly
|
||||
- [ ] Search functionality works with HTMX
|
||||
- [ ] Theme toggle cycles through all modes
|
||||
- [ ] User authentication flows work
|
||||
- [ ] Mobile menu functions correctly
|
||||
- [ ] All buttons and inputs are accessible
|
||||
- [ ] Forms submit via HTMX
|
||||
- [ ] Error states display properly
|
||||
- [ ] Loading states show correctly
|
||||
|
||||
### Automated Testing
|
||||
|
||||
```python
|
||||
# Django tests for HTMX views
|
||||
def test_htmx_partial_response(self):
|
||||
response = self.client.get('/path/', HTTP_HX_REQUEST='true')
|
||||
self.assertContains(response, 'partial content')
|
||||
self.assertNotContains(response, '<html>')
|
||||
```
|
||||
|
||||
### Browser Testing
|
||||
|
||||
```javascript
|
||||
// Alpine.js component tests
|
||||
describe('Theme Toggle', () => {
|
||||
test('cycles through themes', () => {
|
||||
// Test theme cycling functionality
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Deployment Considerations
|
||||
|
||||
### Static Files
|
||||
|
||||
Ensure all new static files are collected:
|
||||
|
||||
```bash
|
||||
uv run manage.py collectstatic
|
||||
```
|
||||
|
||||
### Cache Invalidation
|
||||
|
||||
Update cache keys for new CSS/JS files:
|
||||
|
||||
```python
|
||||
# settings.py
|
||||
STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'
|
||||
```
|
||||
|
||||
### CDN Configuration
|
||||
|
||||
Update CDN settings for new assets:
|
||||
|
||||
```python
|
||||
# For production
|
||||
STATIC_URL = 'https://cdn.example.com/static/'
|
||||
```
|
||||
|
||||
## Migration Benefits

- Ensure Alpine.js component is initialized
|
||||
|
||||
### Debug Tools
|
||||
|
||||
```javascript
