Simple and powerful class system for node js
npm install appolo-class --savevar Rectangle = Class.define({ area: function () { return 25; } }); var rectangle = new Rectangle();creating class with constractor
var Rectangle = Class.define({ constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); var rectangle = new Rectangle(5, 5); console.log(rectangle.area()) // 25var Rectangle = Class.define({ constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); var Square = Class.define({ $config: { extends: Rectangle }, constructor: function (side) { this.callParent(this, side, side); } }); var square = new Square(6); console.log(square.area()) // 36you can also use Class.define fucntion
var Rectangle = Class.define({ constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); var Square = Rectangle.define({ constructor: function (side) { this.callParent(side, side); } }); var square = new Square(6); console.log(square.area()) // 36use this.callParent function to call the parent method
var Rectangle = Class.define({ constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); var Square = Rectangle.define({ constructor: function (side) { this.callParent(side, side); } }); var Cube = Square.define({ constructor: function (side) { this.callParent(side); this.side = side; }, area: function () { return 6 * this.callParent() }, volume: function () { return Math.pow(this.side,3); } }); var cube = new Cube(5); console.log(cube.area()) //150; console.log(cube.volume()) //125;var Rectangle = Class.define({ $config: { statics: { MIN_SIDE: 1, MAX_SIDE: 150 } }, constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); console.log(Rectangle.MIN_SIDE) //1; var rectangle = new Rectangle(5, 5); console.log(rectangle.MIN_SIDE.should.equal(1)) //1;used to add protoype functions from other classes
var Events = Class.define({ bind: function (event, fn) { return true; }, unbind: function (event, fn) { return true; } }); var Rectangle = Class.define({ $config: { mixins: [Events] }, constructor: function (width, height) { this.height = height; this.width = width; }, area: function () { return this.width * this.height; } }); var rectangle = new Rectangle(5, 5); rectangle.bind('test',function(){}) rectangle.unbind('test',function(){})create class on the global scope
Class.define('Test.Position.Base', { constructor: function (symbol, amount, side) { this.symbol = symbol; this.amount = amount; this.side = side; } }); Position.define('Test.Position.Long', { constructor: function (symbol, amount) { this.callParent( symbol, amount, 2); } }); Position.define("Test.Position.Short", { constructor: function (symbol, amount) { this.callParent(symbol, amount, 2); } }); var short = new Test.Position.Short(); var long = new Test.Position.Long();you can define the class name
var Position = Class.define({ constructor: function (symbol, amount, side) { this.symbol = symbol; this.amount = amount; this.side = side; } }); var Long = Position.define({ $config: { name: "long" }, constructor: function (symbol, amount) { this.callParent( symbol, amount, 2); } }); var Short = Position.define({ $config: { name: "short" }, constructor: function (symbol, amount) { this.callParent(symbol, amount, 2); } }); var short = new Short(); var long = new Long(); consloe.log(short.constructor.name) // short console.log(long.constructor.name) //long;define properties with getter and setter functions. if a property in defined to be a member and a getter or setter is not implemented then erro will be trown
var Rectangle = Class.define({ $config: { members: ['area','name'] }, constructor: function (width, height) { this.height = height; this.width = width; }, getArea: function () { return this.width * this.height; }, getName:function(){ return this._name; }, setName:function(value){ this._name = value; } }); var rectangle = new Rectangle(5, 5); console.log(rectangle.area) //25; rectangle.area = 10 // error not implementedyou can your custom plugins to the class system by adding callback function the function will be called with 3 arguments
config- config object of the classklass- class referanceparent- parent class referance
Class.addPlugin(function(config,klass,parent){ //do something }); grunt testThe appolo class library is released under the MIT license. So feel free to modify and distribute it as you wish.
