In Node.js I Can't find the “require('http')” dependacy for using a URL to get image size

Question

I am trying to use the image-size module to get the width of an image via URL. I followed their directions explicitly but can't find the "HTTP" module anywhere (which this seems to require).

I'm fairly new to node.js. Here is my code:

    var url = require('/usr/lib/node_modules/url');
    //  var http = require('/usr/lib/node_modules/http'); *** Can't find this to download
    var imgSize = require('/usr/lib/node_modules/image-size/');

    var imgUrl = 'http://my.nintendo.com/static/images/common/ogp/my-nintendo.png';
    var options = url.parse(imgUrl);

    http.get(options, function (response) {
      var chunks = [];
      response.on('data', function (chunk) {
        chunks.push(chunk);
      }).on('end', function() {
        var buffer = Buffer.concat(chunks);
        console.log(imgSize(buffer));
      });
    });

Here is a link to the package on NPM: https://www.npmjs.com/package/image-size

You must require like this at the top of your file:

var url = require('url');
var http = require('http');

var sizeOf = require('image-size');

You have the module installed in your project node_modules folder?
