Magento 2 is built on a modular system where each module encapsulates a specific feature. This architecture allows developers to extend functionality without modifying core files. A typical module includes structured directories such as **Controller**, **Model**, **View**, and **etc**, ensuring separation of concerns and maintainability.

- registration.php for module registration
- module.xml for configuration declaration
- etc directory for dependency injection and routing
- Controller for handling requests
- Model for business logic
- View for frontend and admin UI

This structured approach enables developers to build scalable and flexible applications that evolve with business needs.

## Best Practices in Magento 2 Module Development

Following best practices ensures code quality, performance, and maintainability. Developers must adhere to coding standards and architectural guidelines to avoid technical debt.

### Follow Coding Standards

Magento adheres to PSR standards, which enforce consistency in code formatting, naming conventions, and structure. Clean code improves readability and reduces onboarding time for new developers.

### Use Service Contracts

Service contracts define clear APIs for modules, promoting loose coupling and backward compatibility. Interfaces should be defined in Api directories to separate logic from implementation.

### Avoid Direct Object Manager Usage

Direct usage of Object Manager leads to tightly coupled code. Instead, dependency injection should be used to manage class dependencies effectively.

### Leverage Plugins and Observers

Plugins allow developers to intercept and modify behavior without overriding core classes. Observers enable event-driven customization, making extensions more stable and upgrade-friendly.

### Repository Pattern

Repositories abstract database interactions, providing a clean interface for CRUD operations. This enhances code clarity and testability.
