I recently bought a PSP and wanted to know the best ISO files and wrote a scraper to retrieve games ISOs titles that received a high rating and send them to a csv. Any recommendations as to readability, and/or better code optimizations?

var request = require('request');
var cheerio = require('cheerio');
var json2csv = require('json2csv');
var fs = require('fs');

var url = 'http://goo.gl/cc4HRc';
var pspISOs = [];

request(url, function (error, response, html) {
  if (!error && response.statusCode === 200) {
    var $ = cheerio.load(html);
    $('.gamelist').each(function () {
    var titles = $(this).text();
    var ratings = +parseFloat($(this)
    pspISOs.push({ title: titles, rating: ratings });
  var topISOs = pspISOs.filter(function (iso) {
    return iso.rating >= 4.81;
  var columns = Object.keys(topISOs[0]);
  json2csv({ data: topISOs, fields: columns }, function (err, csv) {
    if (err) console.log(err);
      fs.writeFile('psp_iso.csv', csv, function (err) {
      if (err) throw err;

After revisiting this, and even though I prefer to handle tasks like this with node, it is possible to write a bash script using curl, and/or xpath that accomplishes this same task. The ratings could filtered with a regex pattern within grep just to lay down a few ideas. Again, this is just an alternative solution.
