In SFCC's MVC architecture, what does a controller do?

In SFCC's MVC architecture, the controller plays a crucial role in bridging the user interface and the business logic of the application. It is responsible for processing user inputs, which can include actions such as form submissions or other interactions. Once the controller receives these inputs, it manipulates the necessary data, possibly interacting with models or services to perform any required business logic. After processing, it determines which view should be rendered as the response, effectively directing the flow of information and rendering the appropriate interface for the user.

This role ensures that the application responds dynamically to user actions, providing a seamless experience and maintaining the responsibility of each architectural component. By managing user inputs and orchestrating data interactions, the controller is fundamental in MVC, making it the key player for the operations that keep the user experience fluent and responsive.
