This is a playground to test JavaScript. It runs a completely standard copy of Node.js on a virtual server created just for you. Every one of npm’s 300,000+ packages are pre-installed, so try it out:
var request = require("request");
var cheerio = require("cheerio");
request('https://news.ycombinator.com', function (error, response, html) {
if (!error && response.statusCode == 200) {
var $ = cheerio.load(html);
$('span.comhead').each(function(i, element){
var a = $(this).prev();
var rank = a.parent().parent().text();
var title = a.text();
var url = a.attr('href');
var subtext = a.parent().parent().next().children('.subtext').children();
var points = $(subtext).eq(0).text();
var username = $(subtext).eq(1).text();
var comments = $(subtext).eq(2).text();
// Our parsed meta data object
var metadata = {
rank: parseInt(rank),
title: title,
url: url,
points: parseInt(points),
username: username,
comments: parseInt(comments)
};
console.log(metadata);
});
}
});
