cla6

Cla6.js

ES6 style class system.

Although originally designed for use with Node.js and installable via npm install cla6, it can also be used directly in the browser.

Cla6 is also installable via:

• bower: bower install cla6

Example

var Cla6 = require('cla6');

var Parent = Cla6('Parent', {
  constructor: function() {
    console.log('parent constructor');
  },

  parentMethod: function() {
    console.log('parent method');
  }
});

var Child = Cla6('Child').extend(Parent, {
  childMethod: function() {
    this.parentMethod();
    console.log('child method');
  },

  get accessor() {
    console.log('child getter');
  },

  set accessor(value) {
    console.log('child setter');
  }
});

child = new Child(); // parent constructor
child.childMethod(); // parent method, child method
child.accessor = child.accessor; // child getter, child setter

Why Use It

• Easy to use
• Easy to read
• Highliy compatible
• Defines classes THE RIGHT WAY

Unlike classic class definition, Cla6 defines unenumerable prototype properties:

// Classic class definition

function Klass() {
  this.foo = 'foo';
  this.bar = 'bar';
}

Klass.prototype.constructor = Klass;

Klass.prototype.baz = function() {
  return 'baz';
};

var instance = new Klass();

// prints foo, bar, baz
for (var k in instance)
  console.log(k);

// Cla6 class definition

var Klass = Cla6('Klass', {
  constructor: function() {
    this.foo = 'foo';
    this.bar = 'bar';
  },

  baz: function() {
    return 'baz';
  }
});

var instance = new Klass();

// prints foo, bar
for (var k in instance)
  console.log(k);

Plugins

Plugins can be applied by Cla6 using the following syntax:

Cla6.use(plugin);

The plugin will be called with the classe's properties object anytime before it gets created, thus the properties can be manipulated. No official plugins are yet available, please stay tuned.

Download
