io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});

↓

module.exports = {
    connect: function(socket) {
        socket.emit('news', { hello: 'world' });
    },
    disconnect: function() {
        console.log("disconnect.");
    },
    onMyEvent: function(data) {
        console.log(data);
    }
};
