create a http server with a put route in javascript

To create an HTTP server with a PUT route in Node.js, you can use the built-in http module. Here's an example code snippet that creates an HTTP server with a PUT route:

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

const server = http.createServer((req, res) => {
  if (req.method === 'PUT' && req.url === '/put-data') {
    let body = '';
    req.on('data', data => {
      body += data;
    });
    req.on('end', () => {
      console.log('PUT data:', body);
      res.end('Successfully received PUT request\n');
    });
  } else {
    res.statusCode = 404;
    res.end('Invalid route\n');
  }
});

server.listen(3000, () => {
  console.log('Server started on port 3000');
});

In this code, we create a server using the createServer() method of the http module. Inside the server callback, we check if the request method is PUT and the URL matches /put-data. If this is true, we listen for a data event and concatenate the data to the body variable, which we log to the console and send back as a response. If the method or URL don't match, we return a 404 error as the response. Finally, we listen for incoming requests on port 3000.
