Singleton Class Extended

Based on singleton-class. The main change is remove the class initialize (new MyClass). The instance created on first `instance` getter call. The constructor logic moved to __initialize method.

Only allows one instance of the singleton to be created

Usage

• npm install --save singleton-class-extended
• Extend the Singleton class with your own

const Singleton = require('singleton-class-extended');
 
class MyClass extends Singleton {
  __initialize(){
    // Use this method as constructor
    this.name = 'bob';
    // Do other things
  }
}
 
console.log(MyClass.instance.name);
