Application Controller
Noun · Development
Definitions
A component responsible for handling incoming actions or requests, coordinating application logic, and returning a response or next view. In frameworks that use controller patterns, application controllers often sit between routing and business services rather than containing all the business logic themselves.
In plain English: The part of an application that receives requests and coordinates what should happen next.
Example: "They thinned the application controller so it only validated input and delegated the real work to service classes."
