Thanks for the reply. This is almost exactly what I wanted to write, especially in terms of programming costs of Rails vs. nodejs.

I am working on a project with exactly the same setup now, Rails for the API and a NodeJS Proxy for the web – works beautifully and with the mature ecosystem around Rails, development of the API has been very easy and focused.

Much of the critique regarding the slowness of Rails relates to earlier versions of both Rails and Ruby, but nowadays it can match the most mature frameworks.
