Error in loading javascript file from node.js

I am trying to use node.js code to run the data in local host, but after I run the code, the javascript file that link inside the Admin Page.html is not running in localhost , and the font file src that wrote inside the Admin Page.html is also not running.How do i fix that? my javascript file is AdminPage.js
complete code for Admin Page.html and AdminPage.js is inside :
https://jsfiddle.net/szeYun/25x6bqLn/
var http =require('http');
var fs = require('fs');
var server = http.createServer(function(req,res){
if (req.url != '/favicon.ico'){
console.log('The request made is: '+ req.url);
}
res.writeHead(200,{'Content-Type':'text/html'});
//res.end('Hello World');
var myReadStream = fs.createReadStream(__dirname + './Admin Page.html' , 'utf8');
myReadStream.pipe(res);
});
server.listen(3000, function(){
console.log('Now the server is listenening on port 3000');
});

POST http://localhost:3000/socket.io/?EIO=3&transport=polling&t=NQUneY3 400 (Bad Request) in ejs and nodejs

I am very new to this socket.io.
I have the code this is a node server code:
var express = require("express");
var app = express();
var http = require("http").createServer(app);
var socketIO = require("socket.io")(http);
var socketID = "";
socketIO.on("connection", function (socket) {
console.log("User is conneected ", socket.id);
socketID = socket.id;
});
And here is the code for a ejs file:
......
<script src="/public/js/socket.io.js"></script>
<script>
......
var socketIO = io("http://localhost:3000");
......
</script>
......
And the socket.io.js file is here:
I tried but nothing is working. The same error pops whenever I refresh the page.
I am very new to this and I really want to get it sorted as soon as possible!!
I already have a listen function just after socket.on:
http.listen(3000, function () {
console.log("Server has started running!!");
.........................
.............
})

The below code is working for me.
var express = require('express');
var app = express();
var server = require('http').Server(app);
var io = require('socket.io')(server);
io.sockets.on('connection', function (socket) {
console.log(socket);
})
server.listen(3000, function(){
console.log('listening on *:3000');
});
<script src="/socket.io/socket.io.js" > </script>
<script>
$(function () {
var socket = io.connect();
});
</script>

socket.io.js that you have mentioned is the same as that from the https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.js... check the installed version of serail io in package.json and place the same version here in the path socket.io/2.2.0 it will work

Please Check versions of socket.io in your Frontend and Backend. It should be compatible. I had same issue so I solved it with version change. Like I had 2.2.0 in my frontend so I install 1.7.2 in backend or same as frontend.

Express js chat application:404 error on socket.io.js file

I am trying to develop a chat application using Express js(jade template ) and socket.io.Here is my app.js
var express = require('express');
var path = require('path');
var http = require('http');
var io = require('socket.io')(http);
var app = express();
//start chat with socket io
io.sockets.on('connection',function(socket){
console.log("connection");
socket.on('send message',function(data,callback){
var msg=data.trim();
if(msg==null){
callback("enter a messsage");
}else{
console.log("chat message"+msg);
io.sockets.emit('new message',{msg:msg});
}
});
});
//end socket
Here is my chat.js file on client side
$(document).ready(function(){
var socket=io.connect('http://localhost:3000');
var $message=$('#message');
var $messageForm=$('#send-message');
//opens a connection and send to sever
$messageForm.submit(function(e){
e.preventDefault();
socket.emit('send message',$message.val(),function(data){
console.log("data"+data);
});
$message.val('');
});
//read the chat messages from users
socket.on('new message',function(data){
console.log('data.msg');
});
});
chat.jade file
<form id="send-message">
<input type="text" id="message">
<input type="submit" value="submit"/>
</form>
<script src="http://localhost/api/jquery.min.js"></script>
<script src="http://localhost:3000/socket.io/socket.io.js"></script>
I will get 404 error on this file http://localhost:3000/socket.io/socket.io.js. Also get a Uncaught ReferenceError: io is not defined in chat.js script.I think this is because of missing socket.io.js file.

You have a couple of issues.
Serving static files in your jade templates you should be using something like this:
link(rel='text/javascript', href='/js/socket.io.js')
These files will normally be contained within a public directory in your express app.
Then in your app.js you should have something like:
app.use(express.static('public'));
Its explained here on the express site - http://expressjs.com/starter/static-files.html
Elsewhere
Uncaught ReferenceError: io is not defined
$(document).ready(function(){
var socket=io.connect('http://localhost:3000');
This is because you havent defined io on your client. You call connect on something called io but havent declared/defined io anywhere.
Also
You havent created a socket server on your app side. You should be doing something along the lines of:
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var port = process.env.PORT || 3000;
server.listen(port, function () {
console.log('Server listening at port %d', port);
});
io.on('connection', function (socket) {
// when the client emits 'new message', this listens and executes
socket.on('new message', function (data) {
// we tell the client to execute 'new message'
socket.broadcast.emit('new message', {
});
});
Example
Socket.io have an example chat app on github that you should use as reference.
Your chat.js would be the equivalent of their public/main.js
Your chat.jade is equivalent to their public/index.html
and your app.js matches their index.js

connection refused node js

Helle every body i desired to test sockets,when i'm connected a alert should appear, it work on the computer where Node js is in installed but not in the other computer.
The error :
Failed to load resource: net::ERR_CONNECTION_REFUSED
http://xxx.xxx.xxx.xxx:8080/socket.io/socket.io.js Uncaught

var fs = require('fs');
var io = require('socket.io');
var server = http.createServer(function(req,res){
res.writeHead(200,{'Content-Type' : 'text/html'});
fs.readFile('./index.html',function(err,content){
res.end(content);
});
}).listen(8080);
io = io.listen(server)
io.sockets.on('connection',function(client){
client.emit('connecte');
});

});
</script>
</html>
sorry for the language english is not my first language i try to learn.
Thanks

The Socket.IO docs shows how to use Socket.IO with the built-in http server. Comparing that example and your code you can see you're not using io quite right. Try something like this:
var http = require('http');
var fs = require('fs');
var io = require('socket.io');
var server = http.createServer(function(req, res){
res.writeHead(200, {'Content-Type': 'text/html'});
fs.readFile('./index.html', function(err, content) {
res.end(content);
});
});
io = io(server);
server.listen(8080);
io.on('connection', function(client) {
client.emit('connected');
});
Also on an unrelated note, you could pipe() the html file to the client instead of buffering the entire file first:
res.writeHead(200, {'Content-Type': 'text/html'});
fs.createReadStream('index.html').pipe(res);

Redis Pub/Sub not displaying published message in client using redis-cli

Hello guys i'm having a problem in redis pub/sub because my client does not show the message i've published in redis-cli. I used the codes found here in stackoverflow and i made some modification. Here is the link and code. I hope you can help me, my goal is to publish the message to the client index.html using redis publish in redis-cli. I've done this before but i can't make it work again. Thanks in advance guys.
Here is my client index.html
<html>
<head>
<title>PubSub</title>
<script src="/socket.io/socket.io.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<!-- <script src="/javascripts/socket.js"></script> -->
</head>
<body>
<div id="content"></div>
<script>
var socket = io.connect('http://localhost:3000');
var content = $('#content');
socket.on('connect', function() {
});
socket.on('message', function (message){
content.prepend(message + '<br />');
}) ;
socket.on('disconnect', function() {
console.log('disconnected');
content.html("<b>Disconnected!</b>");
});
socket.connect();
});
</script>
</body>
</html>
Here is my server.js
var express = require('express');
var app = express();
var redis = require('redis');
var http = require('http');
var server = http.createServer(app);
var socket = require('socket.io').listen(server);
var publish = redis.createClient();
app.listen(3000);
console.log("Express server listening on port 3000")
app.get('/', function (req,res) {
res.sendfile(__dirname + '/public/index.html');
});
socket.on('connection', function (client) {
var subscribe = redis.createClient();
subscribe.subscribe('pubsub');
subscribe.on("message", function (channel, message) {
publish.send(message);
});
publish.on('message', function (msg) {
});
publish.on('disconnect', function() {
subscribe.quit();
});
});

Redis will not send data to connected clients for you. You must instruct Socket.IO to emit data:
subscribe.on("message", function (channel, message) {
socket.emit('message', message);
});
