Websocket chat error in node.js socket.io
Question
Welcome all! I have made a chat with websocket, the best of all is that it includes php, for this I installed this websocket (server side), in a different way.
The problem is the following, when I run the server, and I open the page from localhost/path .. there is an error in the browser,
"Uncaught ReferenceError: io is not defined" at: "var socket = io();" from index.php, chat1.rar file
The server side appears to work, node chat.js
I've been watching for a week how to fix it,
I leave below the mentioned code.
chat.js (server side)
var express = require( 'express' );
var http = require('http');
var socket = require('socket.io');
var bodyParser = require('body-parser')
var PORT = process.env.PORT || 8080;
var fs= require('fs');
var app = express();
var server = http.createServer( app );
var io = socket.listen( server );
io.on('connection',function(socket){
var channel = 'channel-a';
socket.join(channel);
socket.on('message',function(msj){
io.sockets.in(channel).emit('message',msj,socket.id);
});
socket.on('disconnect',function(){
console.log("Desconectado : %s",socket.id);
});
});
server.listen( 1334, function() {
console.log('lisning to port 1334');
});
And index.php (client side)
<!DOCTYPE html>

var mensaje = $("#msg").val();
if(mensaje=='') return false;
if(mensaje==' ') return false;
socket.emit('message',mensaje);
$("#msg").val('').focus();
return false;
});
});
socket.on('message',function(msg,id){
//output.innerHTML += '<p><strong>' + id + ': </strong>' + msg + '</p>';
$('#message').append($('<p><strong>' + id + ': </strong>' + msg + '</p>'));
//$('#message').append($('<div class="msg new-chat-message">').text(id+': '+msg));
//$('#message').append($('<div class="msg new-chat-message">').html('<span class="member-name">' + id + '</span>: ' + msg));
$('.chat-window').scrollTop($('#message').height());
//$("#message").append($('<li>').text(id+' : ' +msg));
});
socket.on('change channel',function(channel){
$("#message").html('').append($('<li>').text('system : Bienvenido al Canal '+channel+' !'));
});
</script>
<div class="col-md-12">

Change this:
<script src="node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js">
To:
<script src="/socket.io/socket.io.js">
And see what happens.
