jsclass-mixin

Mixin JavaScript ES6 based classes made easy & simple.

What Make "jsclass-mixin" Unique

Among other mixin libraries, jsclass-mixin focuses on sticking to ES6 class defining style, thous archiving high level code readability. Code says more than thousand words.

  class Base{
    constructor(a, b){};
  };

  class MixA{
    constructor(a, b){};
    hello(){
      console.log("I am MixA");
    }
  };

  class MixB{
    constructor(c, d){}};
  };

  class MixinSample extends mix(Base, MixA, MixB){
    constructor(a, b, c, d){
      //calling Base constructor
      super(a, b);

      //calling Mixin classes' constructor
      MixA.new(a, b);
      MixB.new(c, d);
    };
  }

How to Use

Just extend your class using mix function.

Some Notes

Method "new()" is Attached Automatically

To archive high level code readability, jsclass-mixin offers a constructor alternative. So developers are able to control mixin classes initialization sequence, and confirm it at a glance within his/her class constructor. The constructor alternative method, "new()" is attached as a static method of mixin classes. Developer can pass a set of arguments as s/he defined in the original constructor to initialize the class as it was originally designed.

Function Ready

"jsclass-mixin" mixies not only properties, but also functions from mixin classes.

No Limitation and Assumption

Developer can use any class as mixin class. Developers does not need to design special class for mixin, "jsclass-mixin" accepts any/every ES6 class!

"instanceof" Works

Mixed classes can now test with normal instanceof operator.

  class MixinSample extends mix(Base, MixA, MixB){
  }

  let obj = new MixinSample();

  //below codes return true
  obj instanceof Base;
  obj instanceof MixA;
  obj instanceof MixB;

"super" Alternative for Mixed Class ([email protected])

While it is not possible to access mixed classes over-ridden methods using super key word, jsclass-mixin provides alternative way to it. You can use mixed property to access mixed classes overriden method.

  class MixinSample extends mix(Base, MixA, MixB){
    hello(){
      console.log("I am MixinSample");
    }
  }

  let obj = new MixinSample();

  obj.hello();
  > I am MixinSample

  //access over-ridden method this way
  obj.mixed.hello();
  > I am MixA
