Gist to try out different API designs for node-websockets WebSocketServer.

wsserver_api.js

// for small text messages
wsserver.on('message', function(message, wssocket) {
  wsserver.broadcast(message);
});

// for large, fragmented messages
wsserver.on('stream', function(request, response) {
  response.select([2, 4, 5]);
  request.pipe(response);
});

// for ping frames
wsserver.on('pong', function(message, wssocket) {
    console.log('ping: ' + message.toString();
});

// for close frames
wsserver.on('close', function(code, wssocket) {
  wsserver.broadcast(wssocket.id + 'left us');
});
