rob-util is a NodeJs module I authored for basic common functions that would get shared between various node modules.

var ru = require('rob-util');

This method abstracts the task of throwing an error on a async method.

This is what an standard async throw method will look like typically: function getContact(id, cb) { db.getContact(id, function(err, data) { if(err) throw err; cb(null, data); }); }

This can get reduced to: function getContact(id, cb) { db.getContact(id, ru.cb.callbackThrow(cb)); }
