Option to add trackers to a certain torrent in WebTorrent

[Qqwy]

I'm testing out WebTorrent, switching over from torrent-stream.
One thing I noticed is that WebTorrent does not seem to have a clear way to add trackers (beside the DHT-network of course) to a certain torrent. Is there a built-in mechanism for this?
If not, I think it would be a very useful feature that might very well speed up many of the torrent requests (at least the ones not needing WebRTC, for now).

WebTorrent parses the magnet link or torrent file (which both contains the trackers) and adds the trackers to the torrent. See parse-torrent

So basically, if I want to add more trackers, I add them as '&tr=http://some.url.com&tr=http://some_other.url.com' to the end of the magnet string?

@Qqwy Correct - adding the additional trackers in the magnet uri would work.

You can also do:

var parseTorrent = require('parse-torrent')
var torrent = parseTorrent('magnet:...')

torrent.announce.push('another tracker')
client.add(torrent, function () { ... })

And, as of v0.43, you can also pass in an announce option to client.add, like this:

var WebTorrent = require('webtorrent')

var client = new WebTorrent()
client.add(torrentId, { announce: [] }, function () { ... })

This adds to the tracker list already specified in the torrentId. Cheers!
