#Pragma Singleton [![Build Status](https://secure.travis-ci.org/pragma-dudes/pragma-singleton.png)](http://travis-ci.org/pragma-dudes/pragma-singleton) [![NPM version](https://badge.fury.io/js/pragma-singleton.png)](http://badge.fury.io/js/pragma-singleton)

Singleton design pattern implementation which easy to use.

Just apply this to any constructor function and all 'new' operators for this constructor will return the same instance.

##Usage
To install just use NPM

```bash
npm install pragma-singleton
```

```javascript
var singleton = require('pragma-singleton');

function Constructor(someValue) {
	this.someValue = someValue;
}

var SingletonConstructor = singleton(Constructor),
	instance1 = new SingletonConstructor('value1'),
	instance2 = new SingletonConstructor('value2');

console.log(instance1 == instance2); // true, because the same instance
console.log(instance2.someValue); // value1, because the value of first created instance

```

Pragma Dudes wish you live long and prosper.
