I wrote this, but errors come up and i dont know how to fix
var http = require('http');
var clientHtml = require('fs').readFileSync('client.html');
var plainHttpServer = http.createServer(function (request, response) {
response.writeHead(200, { 'Content-Type': 'text/html' });
response.end(clientHtml);
}).listen(8080);
var files = require('fs');
var io = require('socket.io').listen(plainHttpServer);
io.set('origins', ['localhost:8080', '127.0.0.1:8080']);
and this error comes, i don't know how to fix, tell me
var io = require('socket.io').listen(plainHttpServer);

TypeError: require(...).listen is not a function
require('socket.io')
returns the socket.io Server class. It's a class, not an instance and thus not something you call .listen()
on. Depending upon what exactly you're trying to accomplish, there are a number of different ways you can use that Server class as you can see here in the doc . For example, you can do this:
const Server = require('socket.io');
const io = new Server(somePort);
or this:
const io = require('socket.io')(somePort);
or to share an existing http server:
const io = require('socket.io')(plainHttpServer);
The below snippet worked for me:
const io = require('socket.io')(server);
...
server.listen(3000)

Do Simply Updated Code here:
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);
server.listen(process.env.PORT || 3000);
console.log('Server is running ');
you need to add cors properly to this and set client request url in cors
const { Server } = require("socket.io")
const cors = require("cors");
app.use(cors());
const server = http.createServer(app)
const io = new Server(server,{
cors: {
origin: "http://localhost:3002" <--- here add client req url
}
});
