Answer 1

function contentType(ext) {
    var ct;

    switch (ext) {
    case '.html':
        ct = 'text/html';
        break;
    case '.css':
        ct = 'text/css';
        break;
    case '.js':
        ct = 'text/javascript';
        break;
    default:
        ct = 'text/plain';
        break;
    }

    return {'Content-Type': ct};
}



    var PATH = 'C:/Users/DELL P26E/node_modules'
    var http = require("http");
    var fs = require('fs');
    var url = require("url");
    var path = require("path")
    var fileName = "D:/index.html";

    var server = http.createServer (function (request, response) {




        var dir = "D:/";
        var uri = url.parse(request.url).pathname;
        if (uri == "/")
        {
            uri = "index.html";
        }
        var filename = path.join(dir, uri);



        fs.readFile( filename,
            function (err, data)
            {
                console.log(err)
                if (err)
                {
                    response.writeHead(500);
                    return response.end('Error loading index.html');
                }

                var ext = path.extname(filename)
                response.setHeader('content-type',contentType(ext));
                response.writeHead(200);
                response.end(data);
            });


    }).listen(3000);

    console.log('Server running on 8124') ;
