How to play?

[DiegoRBaquero]

You don't need to bundle if you are already using the minified standalone file. (You could remove the first line) and use your main.js

About the errors, are you using nvm? I can't imagine another reason as to why root couldn't access /root/.node-gyp/4.2.2

[extensionsapp]

I not using nvm and it is necessary?
I use main.js, but empty page.

[DiegoRBaquero]

Does the torrent gets logged in the browser?

I can download it here: https://btorrent.xyz/#976674fc52bb8e61499e701033a5a4759b5f0d60

You don't need to install WebTorrent's npm package. You can use the webtorrent.min.js

index.html

<!DOCTYPE html>

    <meta charset="UTF-8">
    <title>Title</title>

</head>
<body>

</body>

<script src="https://cdn.jsdelivr.net/webtorrent/latest/webtorrent.min.js"></script>

<script src="main.js"></script>

</html>

main.js

var client = new WebTorrent();

var torrentId = 'magnet:?xt=urn:btih:976674fc52bb8e61499e701033a5a4759b5f0d60';

client.add(torrentId, function (torrent) {

    console.log(torrent);

    var file = torrent.files[0];
    file.appendTo('body');
});

If you're using root try adding --unsafe-perm when installing dependencies and chown the node-gyp folder.

There's an ancient issue regarding this behaviour nodejs/node-gyp#454

[extensionsapp]

It works only your example

[DiegoRBaquero]

Ah, that explains why. This has been answered many times.

It's because WebTorrent in the browser cannot connect to TCP/uTP peers. Public torrents are seeded mostly by desktop clients and are not in the webrtc network.

Check this:

webtorrent/instant.io#93 Is very similar

webtorrent-hybrid dont install.

[DiegoRBaquero]

You can't use webtorrent-hybrid in a website. If you are simply trying to stream a torrent to your pc just use webtorrent download '<HASH>' --vlc this will stream the torrent to VLC

You cannot stream public torrents to a website using WebTorrent.
