Any libraries that can make accessing Google APIs as a service account simpler for NodeJS?

Background: My idea is to create a primarily content-heavy website (think news articles or blog posts) written entirely in nodejs. Since creating content on Google Drive (Google Docs) in particular is very simple, what I would like to do is have Nodejs retrieve the website's content from Google Docs.

Challenge: As far as I can tell, the correct way to do this according to Google is to create a Service Account so that the application can access the files stored on Google Drive without requiring user-intervention in the form of a confirmation. Google provides three libraries--java, python, and php--for server-to-server requests. Does anyone know of anything similar already written by the Node community? I am aware of node-oauth but I've searched through it's source and haven't found anything referencing private keys, which are required for server-to-server interaction, which I'm taking to mean it's not supported. Writing one is also an option, but I'd like to avoid that if at all possible. Looking at the Google-written Java Oauth2 client library makes it pretty clear that it's not an easy task.

Thanks in advance!
