Add without starting download?

[btmdave]

Is there anyway to add a torrent and get it's info, but not start downloading?

From the command line you can list the files in a torrent using the --list option:

$ webtorrent --list "magnet:?xt=urn:btih:a97cf38232f073cbe83c34197437edfd702237c0&dn=Sintel+4k+UHD+ENG+FLAC+ITA+ENG+Sub+DMRip+1744p+X265+ZMachine&xl=3489948077&dl=3489948077"

0   : Sintel.4k.UHD.ENG.FLAC.ITA.ENG.Sub.DMRip.1744p.X265_ZMachine.mkv (3.49 GB)

From the API, there's no simple way to do this at the moment, but you can print out the metadata and then remove the torrent from the client. That would do the trick.

var WebTorrent = require('webtorrent')
var client = new WebTorrent()
client.add(magnetUri, function (torrent) {
  console.log(torrent.parsedTorrent) // or torrent.metadata, torrent.files, etc.  
  client.remove(torrent)
})

@feross how would I go with getting seeder / leecher list from a set of trackers in an array (or from a parsed torrent) without downloading the torrent? I'm a bit confused on this one.

Thanks in advance!

How about

client.add(magnetUri, function (torrent) {
  torrent.files.forEach(file => file.deselect())
})

That way you wouldn't be downloading any files, but still stay in the swarm, i guess. Would that work?

@Svenskunganka Please open a new issue for your question (it has nothing to do with this issue).

@alexeisavca You solution would work 👍

@btmdave You can do this:

client.add(torrentId, function (torrent) {
  // gets called once we have the torrent metadata
  console.log(torrent.files) // access the metadata, etc.
  torrent.destroy()
})

The callback is called as soon as the client has the torrent metadata (and before downloading has started), so destroying the torrent immediately will allow you to just access the metadata.
