Hey !! this is Irusha and in this post you are gonna to learn about the request and response in nodejs and lets jump into code directly.

you got to create a views folder in which you will be creating about.html, home.html and 404.html and outside the folder you got to create server.js. And we will run the following code .Its simple and easy !! you gottta....

server.js

const http = require("http");
const fs = require("fs");

const server = http.createServer((req, res) => {
  console.log(req.url, req.method);

  res.setHeader("Content-Type", "text/html");
  let path = "./views/";
  switch (req.url) {
    case "/":
      path += "index.html";
      break;
    case "/about":
      path += "about.html";
      break;
    default:
      path += "404.html";
      break;
  }
  fs.readFile(path, (err, data) => {
    if (err) {
      console.log(err);
      res.end();
    } else {
      //res.write(data);
      res.end(data);
    }
  });
});

server.listen(3000, "localhost", () => {
  console.log("listening to the 3000 local host");
});
