|
|
|
## Overview
|
|
|
|

|
|
|
|
## Files Created
|
|
|
|
### 1. **Facades**
|
|
|
|
#### `src/Facades/Shop.php`
|
|
- Static accessor for shop-related functionality
|
|
- Provides convenient methods for product browsing and inventory management
|
|
- Type-hinted methods for IDE autocomplete support
|
|
|
|
#### `src/Facades/Cart.php`
|
|
- Static accessor for shopping cart operations
|
|
- Simplifies cart management without needing authentication context
|
|
- Type-hinted methods for IDE autocomplete support
|
|
|
|
### 2. **Services**
|
|
|
|
#### `src/Services/ShopService.php`
|

Core implementation for shop operations:

### 3. **Service Provider Updates**
|
|
|
|
Updated `src/ShopServiceProvider.php` to:
|
|
- Bind `shop.service` to `ShopService` in the container
|
|
- Bind `shop.cart` to `CartService` in the container
|
|
- Register both facades for easy access throughout the application

## Usage Examples
|
|
|
|
### Shop Facade
|
|
|
|
```php
|
|
use Blax\Shop\Facades\Shop;
|
|
|
|
// Get featured products
|
|
$featured = Shop::featured()->with('prices')->get();
|
|
|
|
// Check stock availability
|
|
if (Shop::checkStock($product, 2)) {
|
|
// Add to cart
|
|
}
|
|
|
|
// Search products
|
|
$results = Shop::search('laptop')->paginate(10);
|
|
|
|
// Get available stock
|
|
$available = Shop::getAvailableStock($product);
|
|
```
|
|
|
|
### Cart Facade
|
|
|
|
```php
|
|
use Blax\Shop\Facades\Cart;
|
|
|
|
// Add to cart
|
|
Cart::add($product, quantity: 2, parameters: ['size' => 'L']);
|
|
|
|
// Get cart info
|
|
$total = Cart::total();
|
|
$count = Cart::itemCount();
|
|
$items = Cart::items();
|
|
|
|
// Update and manage
|
|
Cart::update($cartItem, quantity: 5);
|
|
Cart::remove($product, quantity: 1);
|
|
|
|
// Checkout
|
|
$purchases = Cart::checkout();
|
|
```
|
|
|
|
## Benefits
|
|
|
|
1. **Cleaner Code**: No need for `auth()->user()->currentCart()->getTotal()`
|
|
2. **Better Testing**: Easy to mock with `Cart::shouldReceive()`
|
|
3. **IDE Support**: Static methods provide excellent autocomplete
|
|
4. **Consistent Interface**: Unified API across the package
|
|
5. **Type Safety**: All methods are properly type-hinted
|
|
6. **Documentation**: Methods are self-documenting through type hints
|
|
|
|
## Future Improvements
|
|
|
|
Consider implementing additional facades:
|
|
- `Inventory` - For stock management
|
|
- `Purchase` - For purchase operations
|
|
- `Stripe` - For payment processing
|
|
|
|
These were outlined in the `FACADE_SUGGESTIONS.md` document and can be implemented using the same pattern.
|
|
|
|
## Integration
|
|
|
|
The facades are automatically registered in the service container through the `ShopServiceProvider`. They're ready to use immediately after the package is installed:
|
|
|
|
```php
|
|
// No additional configuration needed!
|
|
use Blax\Shop\Facades\Shop;
|
|
use Blax\Shop\Facades\Cart;
|
|
|
|
Shop::featured();
|
|
Cart::add($product);
|
|
```
