Usage

Server

var PeerServer = require('peer').PeerServer({ port: 80, debug: true });

Client

<script type="text/javascript" src="/client/dist/peer.js"></script>

First peer

var connections = {};

p1 = new Peer({ host: 'localhost', port: '8000' });
p1.on('ready', function(id) {
  console.log(id); // => 'some_id_1'
});

p1.on('connection', function(connection) {
  // Sends a message to the other peer. This can even be a blob or JSON.
  connection.send('Hi there!');
  connection.send({ file: new Blob([1, 2, 3])});

  // Probably want to save the connection object.
  connections[connection.metadata.username] = connection;

  if (connection.metadata.username == 'spy') {
    connection.close();
  } else {
    // Add handler for connection data.
    connection.on('data', function(data) {
      console.log(data);
    }
  }
});

Second Peer

p2 = new Peer({ server: 'localhost' });
p2.on('ready', function(id) {
  console.log(id);

  p2.connect('some_id_1', { username: 'friend' }, function(err, connection) {
    connection.send('Hi, bye.');

    connection.close();
  });
});
