I'm trying to use webtorrent in node. Here's my main class that serves as an interface between my code and webtorrent:

'use strict';

const EventEmitter = require('events').EventEmitter;
const WebTorrent = require('webtorrent');
let wtClient = new WebTorrent();

var normalize = (data) => {
  for(let key in data) {

    if(typeof data[key] === 'function' || key[0] === '_') {
      delete data[key];
    }
  }
};

class Client extends EventEmitter {
    constructor () {
      super();
      EventEmitter.call(this);

    }
    status () {

      return new Promise((resolve, reject) => {
        setTimeout(() => {
          return resolve('online');
        }, 250);
        setTimeout(() => {
          this.emit('client:status');
        }, 1250);
      });
    }
    addTorrent (opts) {
      return new Promise((resolve, reject) => {
        try {
          let torrent = wtClient.add(opts.source, (torrent) => {
            this.emit('torrent:' + torrent.infoHash + ':loaded', normalize(torrent));
            resolve(normalize(torrent));
          });

          torrent.on('download', (chunkSize) => {
            console.log(chunkSize);
            this.emit('torrent:' + torrent.infoHash + ':download', chunkSize);
          });
        } catch(err) {
          reject(err);
        }
      });
    }
  };

module.exports = Client;

And then to call it in browser:

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);
});

And here is the output of DEBUG=webtorrent,bittorrent-protocol npm start

root@ubuntu-512mb-lon1-01:~/pTorrent# DEBUG=webtorrent,bittorrent-protocol npm start

This issue is caused by your normalize function. You're calling normalize(torrent) which removes everything that starts with _ which is deleting a bunch of internal properties of the torrent.

You shouldn't delete properties from the torrent object.
