Front Controller Pattern
The front controller design pattern means that all requests that come for a resource in an application will be handled by a single handler and then dispatched to the appropriate handler for that type of request. The front controller may use other helpers to achieve the dispatching mechanism.
Components are:
- Controller: The controller is the initial contact point for handling all requests in the system. The controller may delegate to a helper to complete authentication and authorization of a user or to initiate contact retrieval.
- View: A view represents and displays information to the client. The view retrieves information from a model. Helpers support views by encapsulating and adapting the underlying data model for use in the display.
- Dispatcher: A dispatcher is responsible for view management and navigation, managing the choice of the next view to present to the user, and providing the mechanism for vectoring control to this resource.
- Helper: A helper is responsible for helping a view or controller complete its processing. Thus, helpers have numerous responsibilities, including gathering data required by the view and storing this intermediate model, in which case the helper is sometimes referred to as a value bean.
Latest Design Patterns for Web Development
Design patterns are typical solutions to common problems in software design. Rather than being a code solution, they are general concepts you can implement in your software to expect certain behavior from it. Design patterns are not specific to any programming language or technology, but they can be implemented in different ways depending on the specific technology being used.
Design patterns are used in web development to create applications that are maintainable, efficient, and scalable. They provide a way to structure code and data in a way that is both easy to understand and maintain.
