Simply generates a UUID in both Node.js and the browser. This code was taken from Jeff Ward (jcward.com) and http://stackoverflow.com/questions/105034/how-to-create-a-guid-uuid-in-javascript/21963136#21963136. I simply wanted to turn it into a bower package and an npm package for simplicity.
Install via Bower
bower install simple-uuid --save
In your HTML
<script src="bower_components/simple-uuid/uuid.js"></script>
In your code
var uuid = UUID.generate();
NPM
npm install simply-uuid --save
In your code
var UUID = require('simple-uuid');
var uuid = UUID.generate();
