make a http connect request in javascript

To make an HTTP connect request in JavaScript, you can use the built-in XMLHttpRequest object. Here's an example of how to make a connect request:

index.tsx
const xhr = new XMLHttpRequest();
xhr.open("CONNECT", "http://example.com");

xhr.onload = () => {
  console.log(`Response received: ${xhr.status} ${xhr.statusText}`);
};

xhr.onerror = () => {
  console.log("Request failed.");
};

xhr.send();

In this example, we're creating a new XMLHttpRequest object and calling the open method to specify the HTTP method we want to use (in this case, CONNECT) and the URL of the server we want to connect to.

We then set up two event listeners: onload, which is called when the response is received, and onerror, which is called if the request fails.

Finally, we call the send method to actually send the request to the server.

Note that this example uses the CONNECT method, which is not commonly used in HTTP requests. You would typically use GET, POST, or PUT instead, depending on the specific requirements of your application.
