create a http server with a head route in javascript

To create a HTTP server with a HEAD route in JavaScript, you will need to use the built-in http module in Node.js. Here's an example code:

index.tsx
const http = require('http');

const PORT = 3000;

const handleRequest = (request, response) => {
  if (request.method === 'HEAD' && request.url === '/data') {
    // your HEAD route code here
    response.writeHead(200, { 'Content-Type': 'text/plain' });
    response.end();
  }
};

const server = http.createServer(handleRequest);

server.listen(PORT, () => {
  console.log(`Server listening on port ${PORT}`);
});

In this example, we create a handleRequest function that will be called every time a request is made to the server. We check if the request method is HEAD and the URL is /data, and if so, we execute the code inside the if block.

We then create the server using http.createServer, passing in the handleRequest function. Finally, we start the server by calling its listen method and passing in a port number.

You can replace the code inside the if block with whatever functionality you want your HEAD route to have.
