Error connecting to the Socket server

Navigation

There is some way to catch if the socket server I'm trying to connect to is (off, not available etc.).

This is my code: 

 import http from 'http';
 import socket_io from 'socket.io';

In the event of my button 

  try{

  var net = require('net');
  var client = net.connect(12346, 'localhost');
  client.setEncoding('utf8');

  client.on('data', function(data) {
    console.log("Recibiendo :", arguments)
  });

  client.on('disconnect', function() {
    console.log("Error al conectarme con el servido");
  });

  client.on('end', () => {
    console.log('desconectado del servidor');
  });

  client.on('close', function() {
      console.log('Conexion cerrada');
    });

}catch(error) {
  console.log("Error al conectarme con el servidor :"+error);
}

I have no problems when I run the server, but if the socket server is stopped or I have not started it, it does not show any of my logs and the app corrupts showing me the message:

  

connect ECONNREFUSED 127.0.0.1:12346 and

     

TCPConnectWrap.afterConnect [as oncomplete]

What I need is to show a message that says error when connecting to the server.

That you must do with the event error : 

client.on('error', (err) => {
  console.log('Error al conectarse al servidor', err.message);
});
