Adapter Design Pattern



JavaScript Dev

The adapter pattern helps us to connect or communicate with two or more than two interfaces that are not compatible with each other. In a simple word if we have to consume data from a source which our current implementation doesn't support then we can use this pattern to communicate with incompatible sources.

When to use

  • Accessing data from incompatible sources or interfaces.
  • Don't want to modify legacy code because of its dependency but need to use it anyhow.
  • Scenario where you have to follow open/closed principle
  • You could extend each subclass and put the missing function- ality into new child classes. However, you’ll need to duplicate the code across all of these new classes, which smells bad.
