doXFromUI

doXFromUI is a naming convention used in software development to indicate a method or function that performs operation X in response to a user interface event. The suffix FromUI signals that the method is initiated by UI interaction and typically acts as a bridge to the application's business logic or domain layer. It is not a formal library term, but a descriptive pattern observed in many codebases to clarify responsibility and origin of the action.

In practice, a UI event such as a button click triggers doXFromUI, which collects and validates user input and then invokes a use case, service, or domain method that carries out the actual work. For example, a method named doCreateUserFromUI might validate form data and then call a backend service to create the user. When the operation is asynchronous, teams may adopt a variant such as doXFromUIAsync to reflect that the call may involve awaiting a result or a remote request.

Design considerations for doXFromUI include maintaining a thin UI layer that delegates business logic to the domain layer, handling errors gracefully, and ensuring that UI concerns such as validation messages do not leak into domain code. It is also important to consider asynchronous programming models, thread safety, and user feedback during long-running operations.

Relation to broader patterns: the approach aligns with the command pattern and with architectural patterns like MVC, MVVM, or Clean Architecture, where UI actions delegate to controllers, view models, or use-case services. DoXFromUI can improve readability by signaling the source of a transformation, but it should be used consistently and not as a substitute for clear separation of concerns.
