A function I made that wraps the node http.request function to make it a little more friendly. In my case I am using it for API route testing.

reqUrl.js

// module dependencies
var http = require('http'),
    url = require('url');


 /**
  * UrlReq - Wraps the http.request function making it nice for unit testing APIs.
  * 
  * @param  {string}   reqUrl   The required url in any form
  * @param  {object}   options  An options object (this is optional)
  * @param  {Function} cb       This is passed the 'res' object from your request
  * 
  */
exports.urlReq = function(reqUrl, options, cb){
    if(typeof options === "function"){ cb = options; options = {}; }// incase no options passed in

    // parse url to chunks
    reqUrl = url.parse(reqUrl);

    // http.request settings
    var settings = {
        host: reqUrl.hostname,
        port: reqUrl.port || 80,
        path: reqUrl.pathname,
        headers: options.headers || {},
        method: options.method || 'GET'
    };

    // if there are params:
    if(options.params){
        options.params = JSON.stringify(options.params);
        settings.headers['Content-Type'] = 'application/json';
        settings.headers['Content-Length'] = options.params.length;
    };

    // MAKE THE REQUEST
    var req = http.request(settings);

    // if there are params: write them to the request
    if(options.params){ req.write(options.params) };

    // when the response comes back
    req.on('response', function(res){
        res.body = '';
        res.setEncoding('utf-8');

        // concat chunks
        res.on('data', function(chunk){ res.body += chunk });

        // when the response has finished
        res.on('end', function(){
            
            // fire callback
            cb(res.body, res);
        });
    });

    // end the request
    req.end();
}


// Simple Example (defaults to GET)
mylib.urlReq('http://mysite.local:82/newUser', function(body, res){

    // do your stuff

});



// More complex Example 2
mylib.urlReq('http://mysite.local:82/newUser', {
    method: 'POST',
    params:{
        name: 'Tester',
        email: 'Tester@example.com',
        password: 'password'
    }
}, function(body, res){

    // do your stuff

});
