Base Service #

A BaseService is a class in Laravel that is used to encapsulate the logic around a component, and they may do more than one thing. The Laravel service is a powerful tool for managing class dependencies and performing dependency injection.

A BaseService is basically just a class that handles one thing (single responsibility), so that the functionality that the class provides, can be reused in multiple other parts of the application.

By using a BaseController, developers can reduce the amount of code duplication and make it easier to maintain their application. Additionally, it can help enforce best practices and improve code organization by centralizing common functionality.

In our application, we have created a BaseService named Service inside app/Http/Services folder where different function can be defined which can be extended by other services.
