Singleton libs

Features

This package is used to transform class to singleton. Two methods:

• from a function called withSingleton
• from a decorator @singleton

Installation

npm i @qqsss777/oul-class-singleton

Usages

Functionnal pattern

Export the class with the function withSingleton, e.g.

const SampleClass = withSingleton(
    class MyClass {
      counter: number;
      name = "foo";
      constructor(value: number) {
        this.counter = value;
      }
    },
  );

export default SampleClass;

decorator pattern

First, set experimentalDecorators to true in tsconfig.json. Then add decorator @singleton at the top of the class, e.g.

@singleton
class MyClass {
    counter: number;
    name = "foo";
    constructor(value: number) {
      this.counter = value;
    }
}
