My favorite part of Rails was that it was highly opinionated. There was a right way to do things, and really no wrong way (or else it was not rails).
I have also been impressed with the lean-ness of Node. When dealing with APIs, it seems like Node simply works.
I got a note about this blog post in my email that seemed exactly perfect for what I was searching for: an opinionated approach to Node. Granted, this is not a framework, but a collection of independent components that works well to provide a Rails-like experience in Node.
Love to hear your thoughts on the technologies discussed. And give https://twitter.com/stevensunflash a follow if you like this work.
