Facades can be … - Selection from Learning JavaScript Design Patterns [Book] Programmatic Example Taking our computer example from above. So, As the name suggests, it means the face of the building. Facade design pattern can be applied at any point of development, usually when the number of interfaces grow and system gets complex. Definition The Façade design pattern defines a unified, higher-level interface to wrap a complicated set of interfaces in a subsystem. TravelFacade offers a simple interface to book one of the following options: Flight Booking, Train Booking, Hotel Booking, Flight + Hotel booking, and Train + Hotel booking. This can be used to simplify a number of complicated object interactions into a single interface.

It is a simple pattern that may seem trivial but it is powerful and extremely useful. A Facade Pattern says that just "just provide a unified and simplified interface to a set of interfaces in a subsystem, therefore it hides the complexities of the subsystem from the client". Facade pattern provides a simplified interface to a complex subsystem. JavaScript design patterns #5. The Façade pattern provides an interface which shields clients from complex functionality in one or more subsystems. A Facade is used when an easier or simpler interface to an underlying object is desired. Communication between these two layers takes place via a well-defined API. Often referred to as the "Gang of Four" book the full title is "Design Patterns - Elements of Reusable Object-Oriented Software". It falls under the structural desing pattern category. This API, or façade, hides the complexities of the business objects and their interactions from the presentation layer. In plain words. In this video, join Emmanuel Henri as he goes through the main principles of the facade pattern with syntax examples.
