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.

node-simple-http.js

// module dependencies
const http = require('http');
const url = require('url');
/**
* request - 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
* 
*/
var _request = function(reqUrl, options, cb){
    // incase no options passed in
    if (typeof options === "function") {
        cb = options; options = {};
    }
    // 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
    const 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', res => {
        res.body = '';
        res.setEncoding('utf-8');
        // concat chunks
        res.on('data', chunk => { res.body += chunk });
        // when the response has finished
        res.on('end', () => {
            // fire callback
            cb(res.body, res);
        });
    });
    // end the request
    req.end();
};
// exporting the function
module.exports = {
    request: _request
};

// Simple example (defaults to GET)
const simpleHttp = require('./node-simple-http');

var simpleHttp.request('http://mysite.local:82/new-user', (body, res) => {
    // do your stuff
});

// More complex example 2
simpleHttp.request('http://mysite.local:82/new-user', {
    method: 'POST',
    params:{
        name: 'Tester',
        email: '[email protected]',
        password: '****'
    }
}, (body, res) => {
    // do your stuff
});
