Connecting to MongoHQ with Node.js MongoDB Native

I'm using MongoHQ for a Node.js app I'm deploying on Heroku and couldn't find it plainly documented anywhere how to connect to MongoHQ using node-mongodb-native, so enjoy:

/**
 * NOTE: whitespace added for readability
 *
 * EXAMPLE OPTIONS:
 * var options = {
 *     host: 'flame.mongohq.com',
 *     port: 27087,
 *     db: 'your_db',
 *     username: 'your_username',
 *     password: 'your_password'
 * };
 *

DataProvider = function(options) {

    //store this for later use
    var _parent = this;

    //connect to the db
    this.db = new Db(
        options.db,
        new Server(
            options.host,
            options.port,
            {auto_reconnect: true},
            {}
        )
    );

    //open the db connection and then authenticate
    this.db.open(function(err) {
        _parent.db.authenticate(
            options.username,
            options.password,
            function(err) {
                if (err) {
                   console.log(err);
                }
            }
        );
    });

});
