var peer = client.getClientList().pop().name;
client.peerMsg(message, peer, function(err, response) {});

Send file

var filepath = '/Users/luphia/Documents/Workspace/Playground/logo.png';
var peer = client.getClientList().pop().name;
client.peerFile(filepath, peer, function(err, response) {});

var savePath = '/Users/luphia/Desktop/';

client.on('message', function (data) {
  console.log('%s: %s', data.from, JSON.stringify(data.content));

client.on('file', function (data) {
  console.log('recieve file [%s] from %s', data.from, data.name);
  data.r2x.save(savePath + data.name);
});

client.on('message', function (d) {
  var file = d.content.file;
  if(file) {

  }
  else {
    console.log(d);
  }
});
