How do i create a google places like API in Nodejs using express

I am trying to create a RESTful service in Node.js using express like the Google places API which should be in the following format.

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=%1,%2&radius=%3&name=%4&key=AIzaSyAh4t-qlMYrxnk0XF0Yiu9ZXVFDNfPTCFs

Its very unlike the standard way of passing params to an express app which expects in the following format /google/nearbysearch/place/:location=%1,%2/radius/:radius=%3 and etc..

The challenge here is how to use express and decrypt the response to easily parsing the params to a call. I did extensive research but could not find any links on google or stackOverflow. Thanks for the help.

I hear and have checked out restify (http://mcavage.me/node-restify/) where it allows to pass regex strings to the request url. How do they achieve such in Node.js (solutions without using express will also be helpful).

Thanks Anurag
