This is my first module for tata power

let http = require("http");
let fs = require("fs");
let companyName = "Tata Power Ltd";

let server = http.createServer(function(req, res){
    if(req.url=="/favicon.ico" ){
        res.write("");
        res.end();
    }else if(req.url =="/"){
        var htmldata = fs.readFileSync("./index.html"+req.url);
        res.writeHead(200, {"Content-Type":"text/html"});
        let temphtml = htmldata.toString().replace("{{compname}}",companyName);
        res.write(temphtml);
        res.end();
    }else{
        fs.readFile("./"+req.url, function(err, data){
            if(err){
                res.writeHead(404, {"Content-Type":"text/html"});
                res.write("<h1> No Donuts for you </h1>");
                res.end();
            }else{
                res.writeHead(200, {"Content-Type":"text/html"});
                data.toString().replace("{{compname}}","Hello There")
                let temphtml = data.toString().replace("{{compname}}",companyName);
                res.write(temphtml);
                res.end();
            }
        });
       
    }
});

server.listen(4040, "localhost", function(err){
    if(err){
        console.log(err)
    }else{
        console.log("server is now live on localhost:4040")
    }
})
