    Class.extend Build Status

    Backbone's .extend like inheritance helper for Node.js

    Usage

    You basically got two options:

    // 1. Extend from the blank class
    var Base = require('class-extend');
    var Sub = Base.extend();
     
    // 2. Add the .extend helper to a class
    MyClass.extend = require('class-extend').extend;

    .extend()

    .extend allow you to assign prototype and static methods.

    If no constructor method is assigned, the parent constructor method will be called by default.

    // Extend a class
    var Sub = Parent.extend({
      // Overwrite the default constructor
      constructor: function () {},
     
      // Sub class prototypes methods
      hello: function () { console.log('hello'); }
    }, {
      // Constructor static methods
      hey: function () { console.log('hey'); }
    });
     
    Sub.hey();
    // LOG: hey
     
    var instance = new Sub();
    instance.hello();
    // LOG: hello

    .__super__

    Sub classes are assigned a __super__ static property pointing to their parent prototype.

    var Sub = Parent.extend();
    assert(Sub.__super__ === Parent.prototype);
