Presenter Pattern
The Presenter Pattern is a software design pattern used in user interface (UI) development to separate the presentation logic from the UI components, typically in the context of Model-View-Presenter (MVP) architecture. It acts as an intermediary between the view (UI) and the model (data/business logic), handling user input, updating the view, and coordinating with the model to process data. This pattern improves testability, maintainability, and separation of concerns by decoupling the UI from the underlying business rules.
Developers should learn and use the Presenter Pattern when building applications with complex UIs, especially in desktop, web, or mobile development where testability and clean architecture are priorities. It is particularly useful in scenarios requiring unit testing of presentation logic without UI dependencies, such as in enterprise applications or when following MVP, MVVM, or similar patterns to enhance code organization. For example, in Android development with MVP, it helps manage UI state and business logic interactions efficiently.
