Using Node JS to proxy http and modify response

Question

I'm trying to write a front end to an API service with Node JS.

I'd like to be able to have a user point their browser at my node server and make a request. The node script would modify the input to the request, call the api service, then modify the output and pass back to the user.

I like the solution here (with Express JS and node-http-proxy) as it passes the cookies and headers directly from the user through my site to the api server.

proxy request in node.js / express

I see how to modify the input to the request, but i can't figure out how to modify the response. Any suggestions?

transformer-proxy could be useful here. I'm the author of this plugin and I'm answering here because I found this page when looking for the same question and wasn't satisfied with harmon as I don't want to manipulate HTML.

Maybe someone else is looking for this and finds it useful.
