Node.js with Routing

This program creates a simple HTTP server using Node.js that serves different content based on the URL requested.

Key Features:
Responds with a plain text message for the / route.
Serves an Home.html file when the /Home.html URL is accessed.

Commands
1) npm init
2) npm install nodemon

Create file index.js After that looks like this:
index.js

var http = require("http");
var fs = require("fs");
var path = require("path");
var port = 1515;

var app = http.createServer(function (req, res) {
  const url = req.url;

  if (url === "/Home.html" || url === "/") {
    const filePath = path.join(__dirname, "Home.html");

    fs.readFile(filePath, function (err, data) {
      if (err) {
        res.writeHead(404, { "Content-Type": "text/plain" });
        res.write("404 Not Found");
        res.end();
      } else {
        res.writeHead(200, { "Content-Type": "text/html" });
        res.write(data);
        res.end();
      }
    });
  } else {
    res.writeHead(200, { "Content-Type": "text/plain" });
    res.write("This is Routing Server in Node JS..!");
    res.end();
  }
});

app.listen(port, () => {
  console.log("Your server is started on ", port);
});

      <div class="row">
        <h1>This Is a Home Page..!</h1>
      </div>
    </div>
  </body>
</html>

Your server will start, and your Home.html created in the folder looks like this.
