getting JSON from an http request in NodeJS

I am having trouble returning JSON from an http GET request using NodeJS. I am fairly new to http, javascript, and NodeJS.

Reading through examples and documentation, this is what I have come up with:

var http = require('http');

var options = {
    host: 'some.host.com',
    path: '/some/path'
};

var callback = function(response) {
    var raw = '';
    response.on('data', function(d) {
    raw += d;
    });
    response.on('end', function() {
    var data = JSON.parse(raw);
    });
    return data;
};

http.request(options, callback).end()

I have also tried returning data from inside the response.on scope without any luck. Note that with CURL I can get data without a problem.

1. What am I doing wrong and how can I fix the above cod to get the JSON?

Thanks for all the help!
