README

A professional, variant-centric product catalog package for Laravel 12+. Designed to be a stable foundation for any application that needs structured product data — from a simple internal catalog to a full ecommerce storefront — without locking you into a specific architecture.

Suitable For

Use Case	Description
Product Catalog	Display products with filtering, search, and SEO-friendly slug routing
Online Store	Storefront with prices, discount badges, per-variant stock, and cart-ready data
Simple Ecommerce	Order integration with reserve/release stock and an audit trail of stock movements
Internal Catalog	Internal product database with product codes, cost prices, and custom metadata
Digital & Physical	Mixed catalog — physical variants (tracked stock) and digital (unlimited) in one product
Custom Inventory	Stock already managed externally (ERP, WMS, your own table) — connect it via a single interface

Features

Catalog

Products with lifecycle status: draft → published → archived
Product code (code) as the parent SKU; per-variant SKUs for child variants
Permanent slug routing — URLs stay valid even when the product name changes
Full-text search across name, code, description, and variant SKUs
Taxonomy: Brand, Category (parent–child hierarchy), Tag — all with soft delete

Variants & Options

ProductVariant as the primary sellable unit, not Product
String-based options (Color, Size, etc.) with no separate master table required
Auto-generated label from combined option values: "Red / XL"
Auto-generate SKU from product code + option values
Sale price, compare price (discount), and cost price per variant
Physical dimensions (weight, length, width, height) for shipping calculation
meta JSON for custom attributes without additional migrations

Inventory

Three policies per variant: track (deduct stock), allow (always available), deny (unavailable)
Soft-reserve (reserved_quantity) to hold stock while awaiting payment
Low-stock threshold and alerts
Append-only movement history (audit trail for every stock change)
Driver pattern — swap the stock system without changing application code
Built-in: database (stock in DB) and null (always in stock, for digital products)

Extensibility

Custom inventory driver — integrate your own stock system via a single interface
No forced image schema — integrate spatie/laravel-medialibrary or any media solution you prefer
Events: ProductPublished, ProductArchived, InventoryAdjusted
Configurable table prefix — safe to install alongside any existing schema

Why This Package

Most ecommerce packages bundle payment, cart, and order management alongside the catalog. This package does one thing well: product catalog with variant-centric inventory. You own the order flow.

Product is a presentation entity. ProductVariant is the sellable unit.
Inventory is pluggable — connect your own stock system via a single interface without touching your existing code.
No forced image schema — integrate spatie/laravel-medialibrary or your own solution.
Configurable table prefix — safe to install alongside any existing schema.
Slug routing that survives product renames (Shopee-style permanent route key).

];

Basic Usage

Products

use Aliziodev\ProductCatalog\Models\Product;
use Aliziodev\ProductCatalog\Enums\ProductType;

// Simple product (single SKU)
$product = Product::create([
    'name'              => 'Wireless Mouse',
    'code'              => 'WM-001',        // optional parent SKU / product code
    'type'              => ProductType::Simple,
    'short_description' => 'Ergonomic wireless mouse, 2.4 GHz.',
    'meta_title'        => 'Wireless Mouse — Best Price',
    'meta'              => ['warranty' => '1 year'],
]);

// Lifecycle
$product->publish();    // draft → published, fires ProductPublished event
$product->unpublish();  // published → draft
$product->archive();    // → archived, fires ProductArchived event

// State checks
$product->isPublished();
$product->isDraft();
$product->isArchived();
$product->isSimple();
$product->isVariable();

Variants & Options

use Aliziodev\ProductCatalog\Models\ProductVariant;
use Aliziodev\ProductCatalog\Enums\ProductType;

// Variable product
$product = Product::create([
    'name' => 'Running Shoes',
    'code' => 'RS-AIR',
    'type' => ProductType::Variable,
]);

// Define options
$colorOption = $product->options()->create(['name' => 'Color', 'position' => 1]);
$red  = $colorOption->values()->create(['value' => 'Red',  'position' => 1]);
$blue = $colorOption->values()->create(['value' => 'Blue', 'position' => 2]);

$sizeOption = $product->options()->create(['name' => 'Size', 'position' => 2]);
$size42 = $sizeOption->values()->create(['value' => '42', 'position' => 1]);
$size43 = $sizeOption->values()->create(['value' => '43', 'position' => 2]);

// Create variant
$variant = ProductVariant::create([
    'product_id'    => $product->id,
    'sku'           => 'RS-AIR-RED-42',
    'price'         => 850000,
    'compare_price' => 1000000,    // original price (for sale badge)
    'cost_price'    => 500000,     // internal cost
    'weight'        => 0.350,
    'length'        => 30,
    'width'         => 15,
    'height'        => 12,
    'is_default'    => true,
    'is_active'     => true,
    'meta'          => ['barcode' => '8991234567890'],
]);

// Attach option values to variant
$variant->optionValues()->sync([$red->id, $size42->id]);

// Auto-generate SKU from product code + option values
$variant->load('optionValues');
$suggested = $product->buildVariantSku($variant); // "RS-AIR-RED-42"

// Human-readable label
$variant->displayName();        // "Red / 42"

// Pricing helpers
$variant->isOnSale();           // true — compare_price > price
$variant->discountPercentage(); // 15 (int)

Inventory

use Aliziodev\ProductCatalog\Facades\ProductCatalog;

$inventory = ProductCatalog::inventory(); // resolves configured driver

// Set absolute quantity
$inventory->set($variant, 50);

// Adjust (positive = restock, negative = deduct)
$inventory->adjust($variant, -5, 'sale', $order); // $order is optional reference model

// Query
$inventory->getQuantity($variant);        // 45
$inventory->isInStock($variant);          // true
$inventory->canFulfill($variant, 10);     // true

// Built-in drivers:
// 'database' (default) — tracks stock in catalog_inventory_items
// 'null'               — always in stock, no DB writes (digital/unlimited goods)
// To use null driver: PRODUCT_CATALOG_INVENTORY_DRIVER=null in .env
// For per-variant unlimited stock use InventoryPolicy::Allow instead (more granular)

// Direct model helpers (InventoryItem)
$item = $variant->inventoryItem;
$item->availableQuantity();  // quantity - reserved_quantity
$item->reserve(3);           // increment reserved_quantity
$item->release(3);           // decrement reserved_quantity
$item->isLowStock();         // true if availableQuantity <= low_stock_threshold

Taxonomy

use Aliziodev\ProductCatalog\Models\Brand;
use Aliziodev\ProductCatalog\Models\Category;
use Aliziodev\ProductCatalog\Models\Tag;

// Brand
$brand = Brand::create(['name' => 'Nike', 'slug' => 'nike']);
$product->update(['brand_id' => $brand->id]);

// Category (supports parent–child nesting)
$apparel  = Category::create(['name' => 'Apparel',  'slug' => 'apparel']);
$shoes    = Category::create(['name' => 'Shoes',    'slug' => 'shoes', 'parent_id' => $apparel->id]);

$product->update(['primary_category_id' => $shoes->id]);

// Assign multiple categories
$product->categories()->sync([$apparel->id, $shoes->id]);

// Tags
$tag = Tag::create(['name' => 'new-arrival', 'slug' => 'new-arrival']);
$product->tags()->attach($tag);

Querying

// Status scopes
Product::published()->get();
Product::draft()->get();

// Price range (active variants only)
$product->minPrice();      // float|null
$product->maxPrice();      // float|null
$product->priceRange();    // ['min' => 850000.0, 'max' => 1200000.0] | null

// Stock scope — products with at least one purchasable active variant
// NOTE: variants without an inventoryItem record are excluded from this scope.
// Always create an inventoryItem when creating a variant, even for Allow policy.
Product::inStock()->get();

// Search across name, code, short_description, and variant SKUs
Product::search('RS-AIR')->get();

// Filter
Product::forBrand($brand)->published()->get();
Product::withTag($tag)->inStock()->get();

// Low stock alert
use Aliziodev\ProductCatalog\Models\InventoryItem;

InventoryItem::lowStock()->with('variant.product')->get();

Slug Routing

Slugs use a permanent random route_key suffix (Shopee-style). Renaming a product regenerates the slug prefix but keeps the same route key, so old URLs still resolve.

/catalog/wireless-mouse-a1b2c3d4   ← original slug
/catalog/ergonomic-mouse-a1b2c3d4  ← after rename — same route_key suffix

// Find by slug (both old and new slugs resolve)
$product = Product::findBySlug('ergonomic-mouse-a1b2c3d4');
$product = Product::findBySlugOrFail('ergonomic-mouse-a1b2c3d4');

// Scope variant
Product::published()->bySlug($slug)->firstOrFail();

Enable the built-in read-only API routes:

// config/product-catalog.php
'routes' => [
    'enabled' => true,
    'prefix'  => 'catalog',
],

GET /catalog/products
GET /catalog/products/{slug}

API Resources

use Aliziodev\ProductCatalog\Http\Resources\ProductResource;
use Aliziodev\ProductCatalog\Http\Resources\ProductVariantResource;

$product = Product::with(['brand', 'primaryCategory', 'tags', 'variants'])->findOrFail($id);

return ProductResource::make($product);

Response shape:

{
  "id": 1,
  "name": "Running Shoes",
  "code": "RS-AIR",
  "slug": "running-shoes-a1b2c3d4",
  "type": "variable",
  "status": "published",
  "featured_image_path": null,
  "brand": { "id": 1, "name": "Nike" },
  "variants": [
    {
      "id": 1,
      "sku": "RS-AIR-RED-42",
      "price": 850000,
      "compare_price": 1000000,
      "is_on_sale": true,
      "discount_percentage": 15,

      "width": 15,
      "height": 12,
      "meta": { "barcode": "8991234567890" }
    }
  ]
}

Events

Event	Fired when
`ProductPublished`	`$product->publish()`
`ProductArchived`	`$product->archive()`
`InventoryAdjusted`	Stock changes via `DatabaseInventoryProvider`

use Aliziodev\ProductCatalog\Events\ProductPublished;

class SendNewProductNotification
{
    public function handle(ProductPublished $event): void
    {
        // $event->product
    }
}

Inventory Policies

Set per InventoryItem via policy column:

Policy	Behaviour
`track`	Checks actual quantity; denies when `quantity <= reserved_quantity`
`allow`	Always in stock — overselling permitted (digital goods, pre-order)
`deny`	Always out of stock — variant is unavailable

use Aliziodev\ProductCatalog\Enums\InventoryPolicy;

$variant->inventoryItem()->create([
    'quantity'           => 0,
    'policy'             => InventoryPolicy::Allow,  // never runs out
    'low_stock_threshold' => null,
]);

Spatie Media Library Integration

This package intentionally excludes a built-in image gallery to stay compatible with any media solution your application already uses.

Install spatie/laravel-medialibrary:

composer require spatie/laravel-medialibrary
php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="medialibrary-migrations"
php artisan migrate

Extend the Product model in your application:

<?php

namespace App\Models;

use Aliziodev\ProductCatalog\Models\Product as BaseProduct;
use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;
use Spatie\MediaLibrary\MediaCollections\Models\Media;

class Product extends BaseProduct implements HasMedia
{
    use InteractsWithMedia;

    public function registerMediaCollections(): void
    {
        $this->addMediaCollection('featured')
            ->singleFile()
            ->acceptsMimeTypes(['image/jpeg', 'image/png', 'image/webp']);

        $this->addMediaCollection('gallery');
    }

    public function registerMediaConversions(?Media $media = null): void
    {
        $this->addMediaConversion('thumb')
            ->width(400)
            ->height(400)
            ->sharpen(5);

        $this->addMediaConversion('webp')
            ->format('webp')
            ->quality(80);
    }
}

Important: Laravel's service container bind() does not affect Eloquent relationships. The package's $variant->product() is hardcoded to BaseProduct::class and will still return the base model. Choose one of the two approaches below.

Approach A — Simple (recommended for most projects)

Use App\Models\Product in all your app code. When you get a product through a variant relationship and need media, re-query with your model:

// In your controllers / services — always use your extended model
use App\Models\Product;

$product = Product::with('variants')->findOrFail($id);
$product->getFirstMediaUrl('featured', 'thumb'); // ✓ works

// When coming from a variant relationship, re-query:
$product = App\Models\Product::find($variant->product_id);
$product->getFirstMediaUrl('featured', 'thumb'); // ✓ works

Approach B — Override the relationship (complete solution)

Also extend ProductVariant to return your Product:

// app/Models/ProductVariant.php
namespace App\Models;

use Aliziodev\ProductCatalog\Models\ProductVariant as BaseVariant;
use Illuminate\Database\Eloquent\Relations\BelongsTo;

class ProductVariant extends BaseVariant
{
    public function product(): BelongsTo
    {
        return $this->belongsTo(Product::class); // App\Models\Product
    }
}

Then use App\Models\ProductVariant everywhere in your app code.

Upload and retrieve:

// Upload featured image
$product->addMediaFromRequest('image')->toMediaCollection('featured');

// Upload gallery
$product->addMediaFromRequest('gallery')->toMediaCollection('gallery');

// Get URLs
$product->getFirstMediaUrl('featured', 'thumb');
$product->getMedia('gallery')->map->getUrl('webp');

Custom Inventory Driver

If your application already has its own stock system — your own inventories table, an ERP, or a third-party WMS — you don't have to use the package's catalog_inventory_items table. Implement InventoryProviderInterface and the package will talk to your system instead.

<?php

namespace App\Inventory;

use Aliziodev\ProductCatalog\Contracts\InventoryProviderInterface;
use Aliziodev\ProductCatalog\Exceptions\InventoryException;
use Aliziodev\ProductCatalog\Models\ProductVariant;
use App\Models\Inventory; // your own inventory model
use Illuminate\Database\Eloquent\Model;

class AppInventoryProvider implements InventoryProviderInterface
{
    public function getQuantity(ProductVariant $variant): int
    {
        return Inventory::where('sku', $variant->sku)->value('quantity') ?? 0;
    }

    public function isInStock(ProductVariant $variant): bool
    {
        return $this->getQuantity($variant) > 0;
    }

    public function canFulfill(ProductVariant $variant, int $quantity): bool
    {
        return $this->getQuantity($variant) >= $quantity;
    }

    public function adjust(
        ProductVariant $variant,
        int $delta,
        string $reason = '',
        ?Model $reference = null,
    ): void {
        $record = Inventory::where('sku', $variant->sku)->firstOrFail();
        $newQty = $record->quantity + $delta;

        if ($newQty < 0) {
            throw InventoryException::insufficientStock($variant, abs($delta));
        }

        $record->update(['quantity' => $newQty]);
    }

    public function set(
        ProductVariant $variant,
        int $quantity,
        string $reason = '',
        ?Model $reference = null,
    ): void {
        Inventory::updateOrCreate(
            ['sku'      => $variant->sku],
            ['quantity' => max(0, $quantity)]
        );
    }
}

use Aliziodev\ProductCatalog\Facades\ProductCatalog;

public function boot(): void
{
    ProductCatalog::extend('app', function ($app) {
        return new \App\Inventory\AppInventoryProvider;
    });
}

Activate via .env:

PRODUCT_CATALOG_INVENTORY_DRIVER=app

For more examples (ERP/WMS API, fallback strategy) see docs/custom-inventory-provider.md.

Testing

When writing tests for code that uses this package, set up your test case with migrations and factories:

// tests/TestCase.php
use Orchestra\Testbench\TestCase as OrchestraTestCase;
use Aliziodev\ProductCatalog\ProductCatalogServiceProvider;

abstract class TestCase extends OrchestraTestCase
{
    use \Illuminate\Foundation\Testing\RefreshDatabase;

    protected function getPackageProviders($app): array
    {
        return [ProductCatalogServiceProvider::class];
    }

    protected function defineDatabaseMigrations(): void
    {
        $this->loadMigrationsFrom(
            base_path('vendor/aliziodev/laravel-product-catalog/database/migrations')
        );
    }
}

For tests that need the inventory facade, swap to the null driver so no DB records are required:

// tests/Feature/CheckoutTest.php
use Aliziodev\ProductCatalog\Models\Product;
use Aliziodev\ProductCatalog\Models\ProductVariant;
use Aliziodev\ProductCatalog\Enums\InventoryPolicy;

it('can add item to cart', function () {
    $variant = ProductVariant::factory()->create(['price' => 150000]);

    // Use Allow policy — no inventory record needed
    $variant->inventoryItem()->create(['quantity' => 0, 'policy' => InventoryPolicy::Allow]);

    // ... your test assertions
});

To override the inventory driver in a specific test:

config(['product-catalog.inventory.driver' => 'null']);
