I use railway.js in production for a social bookmarking tool. I come from a rails background but a Rails API has some up and downs. I wanted to try node and have been very impressed. I use railway.js to serve up the iOS API (private beta) and the public beta website. It serves 800 reqs/min on a shared m1.small with one process and I've had no issues with it at all.
It plays a lot more smoothly with MongoDB and I find it far simpler to hook into more modern functionality with Websockets and client side JS rendering. I had a few issues with jugglingdb (which I forked and fixed) and it's all going smoothly.
I still use Rails for some sites but Node and railway.js let me bootstrap the whole API on MongoDB in a few days and get very acceptable performance.
