A Lightweight Cart Package for Laravel

Features

• Secure card information storage and management
• Support for multiple payment gateways
• Recurring payment and subscription management
• Robust validation and error handling
• Highly customizable and flexible architecture

From the package's documentation, here's an example of retrieving a cart for a given user and adding an item to the cart:

$cart = Cart::query()->firstOrCreate(['user_id' => $user->id]);
$cartItem = new CartItem([
    'itemable_id' => $itemable->id,
    'itemable_type' => $itemable::class,
    'quantity' => 1,
]);
 
$cart->items()->save($cartItem);
 
// Or create and store
Cart::query()->firstOrCreateWithStoreItems(
    item: $product,
    quantity: 1,
    userId: $user->id
);

This package also allows you to store multiple items in the cart, and the cart items are polymorphic model associations. You can access the underlying model associated with the CartItem using the itemable() method:

$cartItem->itemable()->first();

Here you can see an example of how it works.
