How do you connect to SocketIO server to server? (2022)

[Pic2490]

I've been on Stackoverflow and have seen solutions to this question but I've tried them and they're outdated.

I start server code and then I open another terminal and run client code but nothing happens. Also sorry in advance for formatting

//Server
import express from 'express'
import chalk from 'chalk'
import http from 'http'
import { Server } from 'socket.io'

const app = express()

//Socket.io
const httpServer = http.createServer(app)
const io = new Server(httpServer)

io.on("connection", (socket) => {

console.log(chalk.bold.blue("Someone Connected"))  

socket.on("room", (room) =>{
   
    console.log(chalk.blue("Someone joined a room"))
    socket.join(room)
})

})

app.get('/', (req, res) => {
res.send("Hello World")
})

const port = process.env.PORT || 3001
httpServer.listen(port, () => {
console.log(chalk.green("Server started port: ${port}"))
})

//Client
import { io } from "socket.io-client"
import chalk from 'chalk'

const socket = io()

socket.on('connect', function () {
console.log(chalk.green('Connected'))
});
