i cant get socket.io address

This is the html of the code

<!DOCTYPE html>
<head>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
    <script src="/socket.io/socket.io.js"></script>
</head>

This is the JavaScript

var express = require('express')
var bodyParser = require('body-parser')
var app = express()
var http = require('http').Server(app)
var io = require('socket.io')(http)
    
app.use(express.static(__dirname))
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({extended: false}))

var server = http.listen(3000, () => {
    console.log('server is listening on port', server.address().port)
})

It gives this error on node

node:events:505
    throw er; // Unhandled 'error' event
    ^
    
Error: listen EADDRINUSE: address already in use :::3000
    at Server.setupListenHandle [as _listen2] (node:net:1380:16)

        syscall: 'listen',
        address: '::',
        port: 3000
    }

And on web inspect this error

GET http://localhost:3000/socket.io/socket.io.js net::ERR_ABORTED 404 (Not Found)

I don't know know if I understood this right, But I think it isn't getting the socket file.
