Clean Architecture — DDD in Laravel

Clean Architecture — The DDD Approach in the Laravel Ecosystem

Using Clean Architecture and Domain-Driven Design (DDD) principles when designing large and complex information systems ensures code stability and scalability.

The 3 Core Layers of the Architecture

• Domain Layer: Business logic, Entities, and Value Objects.
• Application Layer: Use cases and Command Handlers.
• Infrastructure Layer: DB, ORM, external API integrations, and cache.

final class CreateInvoiceHandler {
  public function handle(CreateInvoiceCommand $cmd): Invoice {}
}

Practical Result: Projects using the DDD approach achieve unit test coverage exceeding 85%.
