Uptown


Simplify prototypical inheritance. This tries to provide some simple constructs for providing functionality you get with ES6 classes, such as:

* Constructor functions
* Static class methods
* Getter and setter methods

Install

Using npm:

``sh
npm install uptown --save
`

Using cdn:

`html

`

- dist/uptown.js contains uptown and requires lodash to be loaded separately. Can be used with requirejs.
- dist/uptown.min.js contains minified uptown and dependencies (lodash).

Usage

Use extendify to add the extend method to a class (note: it mutates the original class).

The extend class method takes three options arguments:

1. Object of instance properties
1. Object of static methods and properties
1. Object of getter and setter mutators

`js
var extendify = require('uptown').extendify;

var Original = function() {};

Original.prototype.hello = function(value) {
return 'Hello, ' + value;
}

extendify(Original);

var SubClass = Original.extend({
// Specify a constructor for the new class
constructor: function() {
// Call parent constructor
Original.apply(this, arguments);
},

hello: function(value) {
// Add exclamation point
return Original.prototype.hello.call(this, value + '!')
}
}, {
// Specify static methods and properties
staticMethod: function() {}
}, {
// Specify getters and setters for the new class
foo: {
get: function() {},
set: function() {}
}
});
`

New classes may also be created using the createClass function. The createClass function works just like .extend.

`js
var createClass = require('uptown').createClass;

var Foo = createClass({
constructor: function() {
this.foo = 'bar';
}
});
