This article introduces 5 TypeScript design patterns. There is a certain reference value, and friends in need can refer to it, and I hope it will be helpful to everyone.

However, they can be divided into three distinct groups: Structural patterns deal with relationships between different components (or classes) and form new structures, to provide new functionality. Examples of structural patterns are Composite, Adapter, and Decorator. Behavioral patterns abstract the common behavior between components into an independent entity.

It is a creational pattern because it ensures that no matter how many times we try to instantiate a class, we only have one instance available. Singleton patterns for handling things like database connections, since we want to handle one at a…
