# Storefront Frontend - Alpine.js/Jinja2 Page Template Guide

## 📋 Overview

This guide provides complete templates for creating new customer-facing storefront pages using the established Alpine.js + Jinja2 + Multi-Theme architecture. Follow these patterns to ensure consistency across all store storefronts while maintaining unique branding.

---

## 🔐 Authentication Pages (Available)

Three fully-implemented authentication pages are available for reference:

- **Login** (`app/templates/storefront/account/login.html`) - Customer sign-in with email/password
- **Register** (`app/templates/storefront/account/register.html`) - New customer account creation
- **Forgot Password** (`app/templates/storefront/account/forgot-password.html`) - Password reset flow

All authentication pages feature:
- ✅ Tailwind CSS styling
- ✅ Alpine.js interactivity
- ✅ Theme integration (store colors, logos, fonts)
- ✅ Dark mode support
- ✅ Mobile responsive design
- ✅ Form validation
- ✅ Loading states
- ✅ Error handling

See the [Storefront Architecture Documentation](./architecture.md) (Authentication Pages section) for complete details.

## 🎯 Quick Reference

### File Structure for New Page
```
app/
├── templates/storefront/
│   └── [page-name].html          # Jinja2 template
├── static/storefront/js/
│   └── [page-name].js            # Alpine.js component
└── api/v1/storefront/
    └── pages.py                  # Route registration
```

### Checklist for New Page
- [ ] Create Jinja2 template extending storefront/base.html
- [ ] Create Alpine.js JavaScript component
- [ ] Register route in pages.py
- [ ] Test with multiple store themes
- [ ] Test responsive design (mobile/tablet/desktop)
- [ ] Test dark mode
- [ ] Test cart integration (if applicable)
- [ ] Verify theme CSS variables work
- [ ] Check image optimization

### 3. Route Registration

**File:** `app/api/v1/storefront/pages.py`

```python
from fastapi import APIRouter, Request, Depends
from sqlalchemy.orm import Session
from app.core.database import get_db

router = APIRouter()

@router.get("/[page-route]")
async def [page_name]_page(
    request: Request,
    db: Session = Depends(get_db)
):
    """
    [Page Name] page
    Displays [description]
    """
    # Store and theme come from middleware
    store = request.state.store
    theme = request.state.theme

    return templates.TemplateResponse(
        "storefront/[page-name].html",
        {
            "request": request,
            "store": store,
            "theme": theme,
        }
    )
```

## 🎨 Common Page Patterns

### Pattern 1: Product Grid Page (Homepage, Category)

**Use for:** Homepage, category pages, search results

```javascript
async init() {
    await this.loadProducts();
}

async loadProducts() {
    this.loading = true;
    try {
        const response = await fetch(
            `/api/v1/storefront/${this.storeCode}/products?category=${this.category}`
        );
        const data = await response.json();
        this.products = data.products || [];
    } catch (error) {
        this.error = error.message;
    } finally {
        this.loading = false;
    }
}
```

**Template:**
```html
<div class="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-6">
    <template x-for="product in products" :key="product.id">
        {% include 'storefront/partials/product-card.html' %}
    </template>
</div>
```

---

### Pattern 2: Product Detail Page

**Use for:** Single product pages

```javascript
async init() {
    const productId = this.getProductIdFromUrl();
    await this.loadProduct(productId);
    await this.loadRelatedProducts(productId);
}

async loadProduct(id) {
    const product = await fetch(
        `/api/v1/storefront/${this.storeCode}/products/${id}`
    ).then(r => r.json());

    this.product = product;
    this.selectedImage = product.images[0];
}

addToCartWithQuantity() {
    const shopLayout = window.storefrontLayoutData();
    shopLayout.addToCart(this.product, this.quantity);
}
```

**Template:**
```html
<div class="grid grid-cols-1 lg:grid-cols-2 gap-12">
    <!-- Image Gallery -->
    <div>
        <img :src="selectedImage" class="w-full rounded-lg">
        <div class="grid grid-cols-4 gap-2 mt-4">
            <template x-for="img in product.images">
                <img @click="selectedImage = img"
                     :src="img"
                     class="cursor-pointer rounded border-2"
                     :class="selectedImage === img ? 'border-primary' : 'border-gray-200'">
            </template>
        </div>
    </div>

    <!-- Product Info -->
    <div>
        <h1 class="text-3xl font-bold mb-4" x-text="product.name"></h1>
        <p class="text-2xl font-bold mb-6"
           :style="{ color: 'var(--color-primary)' }"
           x-text="formatPrice(product.price)"></p>
        <p class="text-gray-600 mb-8" x-text="product.description"></p>

        <!-- Quantity -->
        <div class="flex items-center space-x-4 mb-6">
            <label>Quantity:</label>
            <input type="number" x-model="quantity" min="1" class="w-20 px-3 py-2 border rounded">
        </div>

        <!-- Add to Cart -->
        <button @click="addToCartWithQuantity()"
                class="w-full py-3 text-white rounded-lg text-lg font-semibold"
                :style="{ 'background-color': 'var(--color-primary)' }">
            Add to Cart
        </button>
    </div>
</div>
```

---

### Pattern 3: Cart Page

**Use for:** Shopping cart

```javascript
async init() {
    this.loadCart();
}

loadCart() {
    const shopLayout = window.storefrontLayoutData();
    this.cart = shopLayout.cart;
    this.calculateTotals();
}

updateQuantity(productId, quantity) {
    const shopLayout = window.storefrontLayoutData();
    shopLayout.updateCartItem(productId, quantity);
    this.loadCart();
}

removeItem(productId) {
    const shopLayout = window.storefrontLayoutData();
    shopLayout.removeFromCart(productId);
    this.loadCart();
}

get subtotal() {
    return this.cart.reduce((sum, item) => sum + (item.price * item.quantity), 0);
}

get shipping() {
    return this.subtotal > 50 ? 0 : 9.99;
}

get total() {
    return this.subtotal + this.shipping;
}
```

---

### Pattern 4: Search & Filter Page

**Use for:** Search results, filtered product lists

```javascript
filters: {
    search: '',
    category: '',
    minPrice: 0,
    maxPrice: 1000,
    sortBy: 'relevance',
    inStock: true
},

async performSearch() {
    this.loading = true;
    try {
        const response = await fetch(
            `/api/v1/storefront/${this.storeCode}/search`,
            {
                method: 'POST',
                headers: { 'Content-Type': 'application/json' },
                body: JSON.stringify(this.filters)
            }
        );
        const data = await response.json();
        this.results = data.results || [];
    } finally {
        this.loading = false;
    }
}
```

## 🔧 Best Practices

### 1. Theme Integration

Always use CSS variables for store colors:

```html
<!-- ✅ GOOD: Uses theme variable -->
<button :style="{ 'background-color': 'var(--color-primary)' }">
    Buy Now
</button>

<!-- ❌ BAD: Hardcoded color -->
<button class="bg-blue-500">
    Buy Now
</button>
```

### 2. Cart Integration

Always use the storefront layout's cart methods:

```javascript
// ✅ GOOD: Uses storefront layout
const shopLayout = window.storefrontLayoutData();
shopLayout.addToCart(product, quantity);

// ❌ BAD: Direct localStorage manipulation
localStorage.setItem('cart', JSON.stringify(cart));
```

### 3. Loading States

Always show loading indicators:

```javascript
this.loading = true;
try {
    // ... async operation
} finally {
    this.loading = false; // Always executes
}
```

### 4. Error Handling

Always handle errors gracefully:

```javascript
try {
    await this.loadData();
} catch (error) {
    console.error('Load failed:', error);
    this.error = 'Unable to load products. Please try again.';
    // Don't throw - let UI handle gracefully
}
```

### 5. Responsive Images

Use lazy loading and responsive images:

```html
<img :src="product.image"
     :alt="product.name"
     loading="lazy"
     class="w-full h-full object-cover">
```

### 6. Dark Mode

Support both light and dark modes:

```html
<div class="bg-white dark:bg-gray-800 text-gray-900 dark:text-white">
    Content
</div>
```

### 7. Accessibility

Add proper ARIA labels and keyboard navigation:

```html
<button @click="addToCart(product)"
        aria-label="Add to cart"
        role="button">
    Add to Cart
</button>
```
