Why Does Shopware 6 Rely on OOP?

Shopware 6 is built on the Symfony framework, which is fully object-oriented. This means that developers working with Shopware should have a solid understanding of Object-Oriented Programming (OOP) to efficiently develop modules, plugins, and extensions.

What Is Object-Oriented Programming (OOP)?

OOP enables a structured, reusable, and scalable code architecture. The key concepts include:

• 📌 Classes & Objects: Creating reusable code structures
• 📌 Inheritance: Reusing and extending existing classes
• 📌 Polymorphism: Implementing different methods flexibly
• 📌 Encapsulation: Protecting data through restricted access

Example: A Simple Shopware Service Class Using OOP

In Shopware 6, you can create custom services using Dependency Injection:

namespace MyPlugin\Service;

class ProductService {
    public function getProductName(int $id): string {
        return "Product " . $id;
    }
}

Dependency Injection in Shopware 6

Shopware uses Symfony's DI system for loosely coupled services:

namespace MyPlugin\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use MyPlugin\Service\ProductService;

class ProductController extends AbstractController {
    private ProductService $productService;

    public function __construct(ProductService $productService) {
        $this->productService = $productService;
    }

    public function showProduct(int $id) {
        return $this->json(['name' => $this->productService->getProductName($id)]);
    }
}

Conclusion

OOP is essential for Shopware 6 development. By using classes, inheritance, and dependency injection, you can write clean, maintainable, and scalable code.
