I'm trying to get the title tag of a url with cheerio. But, I'm getting empty string values. This is my code:

app.get('/scrape', function(req, res){



    url = 'http://nrabinowitz.github.io/pjscrape/';



    request(url, function(error, response, html){

        if(!error){

                        var $ = cheerio.load(html);



            var title, release, rating;

            var json = { title : , release : , rating : };



            $('title').filter(function(){

                //var data = $(this);

                var data = $(this);

                        title = data.children().first().text();            

                        release = data.children().last().children().text();



                json.title = title;

                json.release = release;

            })



            $('.star-box-giga-star').filter(function(){

                var data = $(this);

                rating = data.text();



                json.rating = rating;

            })

        }





        fs.writeFile('output.json', JSON.stringify(json, null, 4), function(err){



            console.log('File successfully written! - Check your project directory for the output.json file');



        })



        // Finally, we'll just send out a message to the browser reminding you that this app does not have a UI.

        res.send('Check your console!')

    })

});
