read-torrent

Read and parse a torrent from a resource

npm install read-torrent

Usage

var readTorrent = require('read-torrent');

readTorrent('http://my-server.com/file.torrent', function(err, torrent) {
    // we loaded a torrent from a server
});

readTorrent('mydir/file.torrent', function(err, torrent) {
    // we loaded a torrent from a file
});

The torrent result looks like this:

For convenience, read-torrent also support reading magnet uri. Resulting information is limited, though.

// "Leaves of Grass" by Walt Whitman
var uri = 'magnet:?xt=urn:btih:d2474e86c95b19b8bcfdb92bc12c9d44667cfa36&dn=Leaves+of+Grass+by+Walt+Whitman.epub&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80&tr=udp%3A%2F%2Ftracker.publicbt.com%3A80&tr=udp%3A%2F%2Ftracker.istole.it%3A6969&tr=udp%3A%2F%2Ftracker.ccc.de%3A80&tr=udp%3A%2F%2Fopen.demonii.com%3A1337'

readTorrent(uri, function(err, torrent) {
  // we loaded a torrent from a magnet uri
});

Resulting information depends on the contents of the URI, but infoHash is guaranteed for any valid magnet uri.

Command-line interface

There is also a command-line interface available if you install it with -g

npm install -g read-torrent

This installs a program called read-torrent that you simply pass a torrent file or url

read-torrent http://my-server.com/file.torrent

This will print all meta info of the torrent file to the terminal
