socket.io client side in node js

Question

Am I doing something wrong? When I run node client.js. I am getting this error message:

/web/ws/node_modules/socket.io/node_modules/engine.io/lib/server.js:358
  var listeners = server.listeners('request').slice(0);
                         ^
TypeError: Object http://localhost:8080 has no method 'listeners'

    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

Here is my code:

var io = require('socket.io');
var socket = io('ws://localhost:8080');
  socket.on('connect', function () {
    socket.send('hi');
    socket.on('message', function (msg) {
      // my msg
    });
  });

Please suggest something. where I am doing the mistake ?

The problem here is that you are trying to use socket.io package which is for configuring the server.

Instead you need to use socket.io-client package to be able to act as a client.
