kad-python-webrtc

This library is an extension to connect both python and webrtc nodes with kad, an implementation of the Kademlia distributed hash table for Node.js and the browser.

Manual Fix

In order to run the project at the current state the following adjustments have to be made at the dependencies (in node_modules):

node_modules/kad-webrtc/lib/contact.js

line 8: var kademlia = require('../../kad');

node_modules/kad-webrtc/lib/transport.js

line 11: var RPC = require('../../kad').RPC;

node_modules/simple-peer/index.js

line 415: replace function setActiveCandidates(item)

function setActiveCandidates (item) {
      var local = localCandidates[item.localCandidateId]
      var remote = remoteCandidates[item.remoteCandidateId]

      if (local) {
        self.localAddress = local.ipAddress
        self.localPort = Number(local.portNumber)
      } else if (typeof item.googLocalAddress === 'string') {
        // Sometimes `item.id` is undefined in `wrtc` and Chrome
        // See: https://github.com/feross/simple-peer/issues/66
        local = item.googLocalAddress.split(':')
        self.localAddress = local[0]
        self.localPort = Number(local[1])
      }
      self._debug('connect local: %s:%s', self.localAddress, self.localPort)

      if (remote) {
        self.remoteAddress = remote.ipAddress
        self.remotePort = Number(remote.portNumber)
        self.remoteFamily = 'IPv4'
      } else if (typeof item.googRemoteAddress === 'string') {
        remote = item.googRemoteAddress.split(':')
        self.remoteAddress = remote[0]
        self.remotePort = Number(remote[1])
        self.remoteFamily = 'IPv4'
      }
      self._debug('connect remote: %s:%s', self.remoteAddress, self.remotePort)
    }

Prepare

Install dependencies via npm and install wrtc manually

$ npm install
$ npm install wrtc

Compile for browser usage

To use the peer implementation in the browser perform the following steps:

Set the right server url in example/webrtc/web-socket

var serverUrl = 'ws://{CUSTOM_SERVER_IP}:9089';

Run browserify on example/webrtc-peer.js

$ browserify example/webrtc-peer -o example/webrtc-peer.browser.js

Run

For the signalling server (needed for WebRTC) run

$ node example/webrtc/server

To run the hybrid peer (connects to Python Rpc via UDP and to WebRTC Peers) run

$ node example/hybrid-peer

To run the Python Rpc peer, which communicates over UDP, run

$ node example/udp-python-peer

To run the WebRTC peer run

$ node example/webrtc-peer

To run the WebRTC peer in the browser open the following URL in the browser
