While i did see quite a bit of options for node, i haven't been playing around with ORMs in Node too much. ORMs to me refer to those used with relational databases and I haven't done that yet in Node.js. i've just been using MongoDB (mongoose) and Redis (node_redis) - both of which have good libraries.

Also remember that the very nature of JavaScript might make the classic idea of how an ORM is implemented a little different.
