]
 
logging({
  instance: instance,
  servers: servers
})
 
function startHttp () {
  var server = http.createServer()
  websocket.createServer({
    server: server
  }, instance.handle)
  server.listen(8880)
  return server
}
 
function startHttps () {
  var server = https.createServer({
    key: fs.readFileSync(path.join(__dirname, 'certs', 'key.pem')),
    cert: fs.readFileSync(path.join(__dirname, 'certs', 'cert.pem'))
  })
  websocket.createServer({
    server: server
  }, instance.handle)
  server.listen(8881)
  return server
}
 
function startNet () {
  return net.createServer(instance.handle).listen(8882)
}
 
function startTLS () {
  return tls.createServer({
    key: fs.readFileSync(path.join(__dirname, 'certs', 'key.pem')),
    cert: fs.readFileSync(path.join(__dirname, 'certs', 'cert.pem'))
  }, instance.handle).listen(8883)
}

This will logs something like:
