make a http connect request in typescript

To make an HTTP connect request in TypeScript, we can use the built-in http module that is available in Node.js.

Here is an example of how to make a connect request in TypeScript using http:

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

const connectOptions = {
  host: 'example.com',
};
 
const conn = http.request(connectOptions);

conn.on('connect', (res, socket, head) => {
  console.log('connected');
  // Do something with the socket, e.g. via a TCP tunnel
  socket.write('GET / HTTP/1.1\r\n' +
               'Host: example.com\r\n' +
               'Connection: close\r\n' +
               '\r\n');
  socket.on('data', (chunk) => {
    console.log(chunk.toString());
  });
  socket.on('end', () => {
    console.log('disconnected');
  });
});

conn.end();

In this example, we first import the http module. We then define our connect request options including the host we want to connect to. We then create a new http.request() object and pass in the options.

We listen for the connect event which is emitted when the server accepts the connection. We then have access to the socket object which we can use to send data to and receive data from the server.

Finally, we end the connection by calling the end() method on the http.request object.

This is just a basic example, and we can customize the connect request further by adding more options and event listeners as needed.
