make a http options request in typescript

To make an HTTP OPTIONS request in TypeScript, we can use the http module provided by Node.js. Here's an example:

index.ts
import * as http from 'http';

const options = {
  hostname: 'example.com',
  port: 80,
  path: '/',
  method: 'OPTIONS',
};

const req = http.request(options, (res) => {
  console.log(`statusCode: ${res.statusCode}`);
  console.log(`headers: ${JSON.stringify(res.headers)}`);
});

req.on('error', (error) => {
  console.error(error);
});

req.end();

In this example, we first define the request options, including the hostname, port, path, and method (which is set to 'OPTIONS' for this request).

We then use the http.request method to create the request, passing in the options and a callback function to handle the response. Inside the callback, we log the response status code and headers.

If an error occurs, we log it using the console.error method.

Finally, we call req.end() to actually send the request.

Note that this example assumes that the server at example.com supports HTTP OPTIONS requests. If it does not, the request will fail. Additionally, this example uses the http module, which only works in Node.js. If you need to make HTTP requests in a browser environment, you'll need to use a different approach.
