This package is a modular and extensible library designed to strengthen cart management within the Laravel ecosystem. It is classified under the following headings:

• Core Cart: Functions to add, remove, update quantity, and clear cart items.
• Persistence Layer: Durable storage via a migration for cart_items with a JSON-enabled options column and the CartItem model.
• Interface & Contracts: Abstractions through CartInterface, ProductResolverInterface, and TaxCalculatorInterface.
• Events System: ItemAdded, ItemUpdated, ItemRemoved, and CartCleared events.
• Calculators: Subtotal, tax, and total calculation via DefaultCartCalculator and DefaultTaxCalculator.
• Configurable Resolver: Configure the model and tax rate (tax_rate) in config/cart.php.
• Actions: Extendable action framework with examples like MailAction for sending emails.
• Facade & Helpers: Provides a Cart facade and helper functions.

• Cart Management

  • Add/remove/update/clear items (addItem, removeItem, updateQuantity, clear)
  • List items (items) and calculate total (total)

• Database Support

  • DefaultTaxCalculator: percentage-based tax calculation

• Facade

  • Provides the Cart facade

1. Require the package via Composer:

   composer require taskinbirtan/ecommerce.cart

2. Register the service provider and facade (if auto-discovery is disabled) in config/app.php:

   Taskinbirtan\EcommerceCart\CartServiceProvider::class,
   
   'Cart' => Taskinbirtan\EcommerceCart\Facades\Cart::class,

3. Publish the configuration file:

   php artisan vendor:publish --provider="Taskinbirtan\EcommerceCart\CartServiceProvider" --tag=config

4. Run the migrations:

   php artisan migrate

Note: The default migration file is named 1919_05_19_commemorate_ataturk.php in honor of Atatürk and to celebrate Youth and Sports Day, commemorating the beginning of the Turkish War of Independence and marking the date this project was initiated.

config/cart.php:

return [
    'product_model' => App\\Models\\Product::class,
    'tax_rate'      => 18, // percentage
];

use Cart;

Cart::addItem($productId, $quantity = 1, ['color' => 'red']);

Cart::removeItem($productId);

Cart::updateQuantity($productId, $newQuantity);

Cart::clear();

$items = Cart::items();
$total = Cart::total();

You can listen to the following events to react to cart changes:

• Taskinbirtan\EcommerceCart\Events\ItemAdded
• Taskinbirtan\EcommerceCart\Events\ItemUpdated
• Taskinbirtan\EcommerceCart\Events\ItemRemoved
• Taskinbirtan\EcommerceCart\Events\CartCleared

Example listener:

public function handle(ItemAdded $event)
{
    // $event->item
}

This package can be tested with Pest & PHPUnit:

vendor/bin/pest

In future versions, we aim to cover e-commerce components beyond Cart with the following modules:

• Product Catalog: CRUD operations, detail pages, variation support (color, size, etc.)
• Category Management: Multi-level category/ subcategory hierarchy and category-based filtering
• Inventory & Stock Tracking: Warehouse-based stock management, critical stock alerts
• Order Management: Creating orders, status updates, and customer notifications
• Payment Integrations: Stripe, PayPal, local banks, and installment options
• Shipping & Logistics: Carrier API integration, shipment tracking
• Coupons & Discounts: Percentage- and amount-based promo codes, usage rules
• Customer Accounts: Registration/login, profile, address book, order history
• Invoicing & Returns: PDF invoice generation, return request management
• Multi-Language & Multi-Currency: Localization infrastructure, currency rate updates
• Reporting & Analytics: Sales, customer, and stock reports with graphical displays
• Search & Filtering Infrastructure: Elasticsearch/Algolia integration, advanced filters
• UI/UX Components: Responsive theme and demo components (Tailwind, jQuery)
• Security & Performance: Rate limiting, cache (Redis), scalable architecture recommendations

• Fork the repository
• Create a new branch (git checkout -b feature/fooBar)
• Commit your changes (git commit -am 'Add some fooBar')
• Push to the branch (git push origin feature/fooBar)
• Open a pull request
