get connected peer list and their progress

[souravndp]

I want to use webtorrent in the browser. I need to get the list of connected peers and their progress. eg: 13.234.5.156, 95% ; 134.67.54.3, 100% etc.

I have looked into API section and found out torrent.numPeers and torrent.on('wire', function (wire) {}). but didn't find any specific tutorial/help for my requirement. torrent.numPeers returns the total number of peers but I need connected peers. Also, it is mentioned torrent.on('wire', function (wire) {}) is emitted whenever a new peer is connected for this torrent. but how to get the IP of the peer?

Is this feature available? If yes, can you please point me towards the right direction?

You'd be best scraping a tracker or creating a backend where you send that information. The wire API can be found here: https://github.com/feross/bittorrent-protocol, but you can only query the stats between you as a peer and that peer.

If the peers are TCP/UDP (Won't work on browser), you can get the IP using wire.addr

Btw, torrent.numPeers does return the number of currently connected peers.

You might be able to get the info you need by listening to the 'wire' event, actually:

torrent.on('wire', function (wire) {
  var downloaded = 0
  for (var index = 0, len = torrent.pieces.length; index < len; ++index) {
    if (wire.peerPieces.get(index)) {
      downloaded += (index === len - 1) ? torrent.lastPieceLength : torrent.pieceLength
    }
  }
  var percentComplete = (downloaded / torrent.length) * 100
  console.log('Peer ' + wire.addr + ' connected with ' + percentComplete + '% complete')
})

(Untested, but something like that should work)

@feross Thank you for your help. I will test the code later. just for information, is this okay to post such questions asking for help here? After all, the section is named as 'issues'. Or, should I post this to some place else, like StackOverflow? I would prefer to post here if this is not much a problem.

Posting questions is fine, but ideally you would chat with others on https://gitter.im/feross/webtorrent first 👍 Or if you use IRC, that chat room is linked to #webtorrent on freenode.
