How to get number of video views with YouTube API?

Here is a small code snippet to get Youtube video views from URL using Javascript

Demo of below code

    function videoViews() {
var rex = /[a-zA-Z0-9\-\_]{11}/,
    videoUrl = $('input').val() === '' ? alert('Enter a valid Url'):$('input').val(),
    videoId = videoUrl.match(rex),
    jsonUrl = 'http://gdata.youtube.com/feeds/api/videos/' + videoId + '?v=2&alt=json',
   embedUrl = '//www.youtube.com/embed/' + videoId,
   embedCode = '<iframe width="350" height="197" src="' + embedUrl + '" frameborder="0" allowfullscreen></iframe>'


//Get Views from JSON
$.getJSON(jsonUrl, function (videoData) {
    var videoJson = JSON.stringify(videoData),
        vidJson = JSON.parse(videoJson),
        views = vidJson.entry.yt$statistics.viewCount;
    $('.views').text(views);
});

//Embed Video
$('.videoembed').html(embedCode);}

Why using any api key to retrieve a portion of public html!

Simplest unix command line demonstrative example, using curl, grep and cut.

curl https://www.youtube.com/watch?v=r-y7jzGxKNo | grep watch7-views-info | cut -d">" -f8 | cut -d"<" -f1

Yes, it get the full html page, this loss has no meaning against the countless advantages.

Using youtube-dl and jq:

views() {
    id=$1
    youtube-dl -j https://www.youtube.com/watch?v=$id |
        jq -r '.["view_count"]'
}
