New library for Emoji shortcodes!

I have been spending my time developing a NodeJS library that makes it easy to use the universal emoji shortcodes that can be found here:
http://www.emoji-cheat-sheet.com/

It follows a simple usage syntax where you simply pass in a string containing shortcodes, and get a string containing the appropriate Unicode characters as a result:

var codex = require("emoji-codex"); 

var string = "Hello! :relaxed:";

var translated = codex.translate(string);

You can find it here:
https://github.com/entropy-js/emoji-codex

Or simply:

npm install emoji-codex 

Let me know what you think!
