discovery-swarm

A network swarm that uses discovery-channel to find and connect to peers.

This module implements peer connection state and builds on discovery-channel which implements peer discovery. This uses TCP sockets by default and has experimental support for UTP.

npm install discovery-swarm

Usage

var swarm = require('discovery-swarm')

var sw = swarm()

sw.listen(1000)
sw.join('ubuntu-14.04') // can be any id/name/hash

sw.on('connection', function (connection) {
  console.log('found + connected to peer')
})

API

var sw = swarm()

Create a new swarm

sw.join(key)

Join a channel specified by key (usually a name, hash or id, must be a Buffer or a string). After joining will immediately search for peers advertising this key, and re-announce on a timer.

sw.leave(key)

Leave the channel specified key

sw.connecting

Number of peers we are trying to connect to

sw.queued

Number of peers discovered but not connected to yet

sw.connections

List of active connections to other peers

sw.on('connection', connection, info)

Emitted when you connect to another peer. Info is an object that contains info about the connection

{
  type: 'tcp', // the type, tcp or utp
  initiator: true, // wheather we initiated the connection or someone else did
  channel: Buffer('...'), // the channel this connetion was initiated on. only set if initiator === true
  host: '127.0.0.1', // the remote address of the peer.
  port: 8080, // the remote port of the peer.
  id: Buffer('...') // the remote peer's peer-id.
}

sw.listen(port)

Listen on a specific port. Should be called before add
