所以这是一个使用 webtorrent 的简单函数：

addTorrent (opts) {
  return new Promise((resolve, reject) => {
    try {
      console.log('in try catch');
      let torrent = wtClient.add(opts.source, (torrent) => {
        console.log('client.add callback');
        var nled = normalize(torrent);
        console.log('normalized ', torrent.infoHash);
        resolve(nled);
      });
      console.log('after add')
      torrent.on('download', (chunkSize) => {
        console.log(chunkSize);
        this.emit('torrent:' + torrent.infoHash + ':download', chunkSize);
      });
      console.log('after on');
    } catch(err) {
      console.log(pe.render(err));
      process.exit(1);
      reject(err);
    }
  });
}

并称之为：

var MAGNET_URI = 'magnet:?xt=urn:btih:09e37f73e51f403bb543517f0d0a2e1283d61eb0&dn=archlinux-2015.12.01-dual.iso&tr=udp://tracker.archlinux.org:6969&tr=http://tracker.archlinux.org:6969/announce';
socketClient.connect().then(() => {
    console.log('Connected to webtorrent');
    return socketClient.status();
}).then((res) => {
    console.log(res);
    return socketClient.addTorrent({source: MAGNET_URI});
}).then((data) => {
    console.log('Added torrent:', data);
}).catch((err) => {
    console.log(err);
});

这是输出：

并16384重复，直到内存不足。

编辑：经过一番研究，事实证明 16384 是每个 x 以非常高的速率接收的字节（因为我在 VPS 上）。我的 torrent 将在几秒钟内成功下载（在 /tmp/webtorrent/ 中找到它：D）

但是，这并不能解决由resolve();线路引起的 RangeError

RangeError 是由我的 normalize 函数引起的，它会留下对象并使其太大。
