Importing moment.js in to a Code Task

We have been using moment.js to format dates imported via Salesforce outbound message connections. This works well in a survey where we can include the script src in the header of the survey and then add a Javascript block at the top of our survey. However, when we need a formatted date in a survey invitation email we usually will push the formatting responsibility back in to Salesforce where we have a formula field handle the work. The resulting string is then imported and used as a merge field in the email.
Now we have Code Tasks which at first glance appear to be a great tool for formatting Salesforce imported data for use in our survey invitation emails. The question is can we import moment.js ? Is there a way to do this or is a similar feature available already in the implementation of node.js that supports the Code Tasks?
