torrent-tracker-health

Get health info for torrents. This module is based on torrent-tracker and returns the number of seeds and peers.

Quickstart

npm install torrent-tracker-health

Usage

var torrentHealth = require('torrent-tracker-health');
var magnet = 'magnet:?xt=urn:btih:9A7290F4021048D2C176A84828E441FCB5400FB1&dn=charlie+chaplin+15+short+films+1914+1917+dvdrip&tr=udp://tracker.coppersurfer.tk:6969/announce&tr=udp://glotorrents.pw:6969/announce&tr=udp://tracker.openbittorrent.com:80/announce';

torrentHealth(magnet).then(function (res) {
    console.log('seeds:', res.seeds);
    console.log('peers:', res.peers);
    console.log('ratio:', +(Math.round((res.peers > 0 ? res.seeds / res.peers : res.seeds) +'e+2') + 'e-2'));
}).catch(function (err) {
    console.log('error:', err);
});

Options

• blacklist: prevent forcefully to connect to the said tracker(s)

  • a String, a RegExp, an Array of Strings or an Array of RegExps
  • example: prevents connection to any tracker on openbittorrent.com and any tracker using port 80

    torrentHealth(magnet, {
        blacklist: ['openbittorrent.com', ':80']
    });

• timeout: timeout in milliseconds before a call to the tracker ends. Defaults on 400.

  • example: don't try to connect to tracker for more than 10 seconds

    torrentHealth(magnet, {
        timeout: 10000
    });

• force: force a tracker to be added to the magnet's list of trackers.

  • a String, an Array of Strings
  • example: add udp://mycustomtracker.com:6969/announce to the list of trackers

    torrentHealth(magnet, {
        force: ['udp://mycustomtracker.com:6969/announce']
    });

• debug: print various messages to console.log. Default to false

  • example:

    torrentHealth(magnet, {
        debug: true
    });

Going further

• The module can accept different inputs.

  • By default, it is: torrentHealth(magnet [, options, debug])
  • An object can be used alone:

    torrentHealth({
        uri: magnet,
        timeout: 1000,
        force: ['udp://mycustomtracker.com:6969/announce'],
        blacklist: ['openbittorrent'],
        debug: true
    });

• If the module couldn't contact any of the trackers, it will give an output of:

{
    seeds: 0,
    peers: 0
}

• The output contains a results Array, which has information on specific trackers that were called, and their respective responses.
