Shows how easy it is to scrape a site using Node.js and cheerio.

Note: Currently doesn't work because the site was changed

var http = require('http');
var request = require('request');
var cheerio = require('cheerio');
var RSS = require('rss');

function createFeed(html) {
  var $ = cheerio.load(html);
  var feed = new RSS({
    title: 'JSHint Changelog',
    description: 'JSHint is a community-driven tool to detect errors and potential problems in JavaScript code and to enforce your teams coding conventions.',
    feed_url: 'http://feeds.feedburner.com/JSHint-Changelog',
    site_url: 'http://www.jshint.com'
  });

  // Remove the last "Hello" row
  $('.row').last().remove();

  $('.row').each(function () {
    var $this = $(this);
    var title = $this.find('h2').text();
    var date = $this.find('.span5 h3').text();

    // Remove title and date from body
    $this.find('h2, h3').remove();

    feed.item({
      title: title,
      description: $this.html(),
      url: 'http://www.jshint.com/changelog/',
      // Make the data parseable by removing the `th` after the month
      date: date.replace(/ d{1,2}w{0,2}/, function (match) {
        return ' ' + parseInt(match, 10);
      })
    });
  });

  return feed.xml();
}

http.createServer(function (req, res) {
  var serverRes = res;

  request('http://www.jshint.com/changelog/', function (err, res, body) {
    if (!err && res.statusCode === 200) {
      serverRes.writeHead(200, {
        'Content-Type': 'application/rss+xml'
      });
      serverRes.end(createFeed(body));
    }
  });
}).listen(process.env.PORT || 5000);
