How to get rid of multiple messages after reconnecting to webSockets?

Question

JavaScript

Hello, I decided to use socket.io. Everything was fine until a few messages from the server began to arrive.
After reconnection, incoming messages from the server were duplicated. As if after the disconnect was triggered, the socket.onmessage event handler was not deleted.

socket = io.connect('http://locahost/');

socket.on('connect', function () {
  socket.on('reconnect', function(){
    console.log('Пеподключился');
  });
  
  socket.on('disconnect', function(){
    console.log('Отключился');
  });

  socket.on('message', function(obj) {
    console.log('Пришло сообщение');
  });
});

Answer 1

do not bind events inside the connection.
when reconnecting, the connect event fires and again all socket.ons are bound.
As a result, as many reconnects as many duplicates

Answer 2

Do you have socket.io working? Is it installed via npm?
