Facade Pattern
Provide a unified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.
Facade pattern provides a simplified interface to a library, a framework, or any other complex set of classes.
Core Design Challenge
"How do we simplify interaction with a complex set of internal libraries?"
What You'll Learn:
- ✦Providing a simplified interface to a complex subsystem
- ✦Defining entry points to decouple callers from subsystem internals
- ✦Reducing dependencies and improving codebase manageability
- ✦Exposing simple methods without hiding the underlying subsystem
