Here’s a simple example of how you can dynamically route a server in pure vanilla NodeJS without any packages :

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

  if (req.url === "/about") {
    res.end("This is the About page");
  } else if (req.url === "/contacts") {
    res.end("This is the contacts page");
  } else {
    res.end("Hello from the server");
  }
});

server.listen(8000, "localhost", () => {
  console.log("Server started successfully!");
});

Steps :

• http module activated by ‘requiring http’
• Server started on port 8000 (localhost:8000/)
• Activated the server by using the request(req), response(res) cycle
• ‘/about’ and ‘/contacts’ the routes which shows the messages
