Server.js

const http  = require('http');
const url = require('url');
const path = require('path');
const fs = require('fs');

const mimeTypes = {
    "html" : "text/html",
    "jpeg" : "text/jpeg",
    "jpg"  : "text/jpg",
    "png"  : "text/png",
    "js"  : "text/javaScript",
    "css"  : "text/css"
};
http.createServer(function(req,res){
     var  uri = url.parse(req,url).pathname;
    let fileName = path.join(process.cwd(),unescape(url));
    Console.console.log('Loading'+uri);
    let stats;
    try {
        stats = fs.lstatSync(fileName);
    } catch (error) {
        res.writeHead(404,{'Content-type':'text/plain'});
        res.write('404 Not Found\n');
        res.end();
        return;
    }
    if(stats.isFile){
        let mimeType = mimeTypes[path.extname(fileName).split(".").reverse()[0]];
        res.writeHead(200,{'Content-type':MimeType});

        let fileStream = fs.createReadStream(fileName);
        fileStream.pipe(res);
    }else if(stats.isDirectory()){
        res.writeHead(302,{
            'location' : 'index.html'
        });
        res.end();
    }else{
        res.writeHead(500,{'Content-type':'text/plain'});
        res.write('500 Internal error\n');
        res.end();
    }
    
}).listen(3000);

This is the my custom setup of server ,but it is not working ,How to handle this type of issue I take reference from internet ,but I am not able to find my mistake how can I setup my own server setup. which is the better way to define custom server setup

The error is coming from this line:

var  uri = url.parse(req,url).pathname;

It needs to be:

var  uri = url.parse(req.url).pathname;

The function url.parse() expects a string (see in the error: "The "url" argument must be of type string"), but instead it's getting an object (req). Changing it to req.url gets you the url prop on the req object.
