Nexus Laravel Sales Adapter

This adapter provides Laravel-specific implementations for the Sales package, enabling integration with other Nexus packages.

Purpose

The Sales package is an atomic package that must remain independently publishable. This adapter layer provides the concrete implementations that integrate Sales with other packages like:

• Nexus\Receivable - For credit limit checking and invoice generation
• Nexus\Inventory - For stock reservation and availability checking

Installation

composer require azaharizaman/nexus-laravel-sales

Adapters Provided

ReceivableCreditLimitCheckerAdapter

Implements Nexus\Sales\Contracts\CreditLimitCheckerInterface by delegating to Nexus\Receivable\Contracts\CreditLimitCheckerInterface.

InventoryStockReservationAdapter

Implements Nexus\Sales\Contracts\StockReservationInterface by delegating to Nexus\Inventory\Contracts\ReservationManagerInterface.

ReceivableInvoiceManagerAdapter

Implements Nexus\Sales\Contracts\InvoiceManagerInterface by delegating to Nexus\Receivable\Contracts\ReceivableManagerInterface.

Service Provider

The SalesAdapterServiceProvider automatically binds the Sales interfaces to their adapter implementations when all required packages are available.

Architecture

This follows the Nexus Three-Layer Architecture:

1. Atomic Layer (packages/Sales) - Pure business logic, no external dependencies
2. Adapter Layer (adapters/Laravel/Sales) - Framework-specific implementations
3. Application Layer - Uses adapters through interfaces
