MVP Architecture
MVP (Model-View-Presenter) is a software architectural pattern that separates an application into three interconnected components: the Model (data and business logic), the View (user interface), and the Presenter (mediator that handles user input and updates the View). It is derived from the MVC pattern but emphasizes a clearer separation of concerns, with the Presenter acting as a middle layer to decouple the View from the Model, making the code more testable and maintainable. This pattern is commonly used in desktop, web, and mobile applications to structure code for better scalability and easier unit testing.
Developers should learn MVP when building applications that require a clean separation between UI and business logic, especially in scenarios where testability and maintainability are priorities, such as in large-scale enterprise projects or mobile apps (e.g., Android development). It is particularly useful for reducing the complexity of user interface code, as the Presenter handles all interaction logic, allowing the View to be passive and easily mockable for testing. Use cases include GUI applications, web frontends with complex state management, and projects where multiple developers need to work on different layers independently.
