Decorator Pattern
Explore the Decorator pattern to understand how it dynamically augments specific objects in Node.js without affecting all instances. Learn implementation strategies including composition, object augmentation, and Proxy-based decoration, with practical examples to enhance object behavior safely.
We'll cover the following...
Decorator pattern is a structural design pattern that consists of dynamically augmenting the behavior of an existing object. It’s different from classical inheritance because the behavior is not added to all the objects of the same class, but only to the instances that are explicitly decorated.
Implementation-wise, it’s very similar to the Proxy pattern, but instead of enhancing or modifying the behavior of the existing interface of an object, it augments it with new functionalities, as described in the illustration below.
In the above illustration, the Decorator ...
