Youtube channel RSS url

Since i dont have a Youtube account, but i still want to be subscribed to some great channels, i use their RSS url. The problem with this is that although they are available, Youtube doesnt make them public in their website. So i always return to this excellent answer. As i dont want to lose it, im going to copy it here.

If you have the ChannelID, you can make it with the following way https://www.youtube.com/feeds/videos.xml?channel_id=ChannelID.

Or you can always execute this snippet in the console devtools to get the url.

for (var arrScripts = document.getElementsByTagName('script'), i = 0; i < arrScripts.length; i++) {
    if (arrScripts[i].textContent.indexOf('externalId') != -1) {
        var channelId = arrScripts[i].textContent.match(/\"externalId\"\s*\:\s*\"(.*?)\"/)[1];
        var channelRss = 'https://www.youtube.com/feeds/videos.xml?channel_id=' + channelId;
        var channelTitle = document.title.match(/\(?\d*\)?\s?(.*?)\s\-\sYouTube/)[1];
        console.log('The rss feed of the channel \'' + channelTitle + '\' is:\n' + channelRss);
        break;
    }
}

Another option is to add this Subscribe bookmarklet to your bookmarks and just click it.
