Leveraging Service Classes in Laravel: A Step-by-Step Guide

When we talk about clean and maintainable code, separating concerns comes to the forefront. One of the tools Laravel developers can employ to achieve this is the use of service classes. A service class in Laravel, or any other framework for that matter, aims to extract the business logic from controllers, making the application cleaner, more modular, and more testable.

Why Use Service Classes?

1. Separation of Concerns: By keeping the business logic away from the controllers, we ensure that controllers remain slim and focused only on handling HTTP-related tasks.
2. Reusability: Services can be reused across different parts of an application, ensuring the DRY (Don’t Repeat Yourself) principle.
