objectjs

Extendable object in javascript

Installing

npm install objectjs

Using

var ObjectJs = require('objectjs');
 
///////////////////////////////////////////////////
// Create object A
///////////////////////////////////////////////////
A = ObjectJs.extend({
  value: null,
  init: function() {
    this.value = 0;
  },
  get: function() {
    return this.value;
  },
  set: function(value) {
    this.value = value;
  }
});
 
// A.init will be called automatically
// A.value is equal 0
// A.get() will return 0
// if A.set(100) then A.value and A.get() will be equal 100
 
///////////////////////////////////////////////////
// Extend A object
///////////////////////////////////////////////////
A.extend({
  init: function() {
    this.value = 200;
  },
  get: function() {
    return 'value=' + this._super();
  },
  test: function(){
    return 'hello moto';
  }
});
 
// A.value is equal 200
// A.get() is equal `value=200`. `this._super` will refer to parent function which return `this.value`
// A.test() is equal `hello moto`
 

Note:

• this._super() does not work in async because it will be cleared up at the end of the function. You may need to use var _super = this._super before call async.
• You can extend many levels as you want.
• Be careful with this object. Take advantage of the best practice below:
