A library called Flashheart is also a suitable alternative. It's a rest client designed to be easy to use and supports retries.

For example, configure Flashheart to retry 10 times, with a delay of 500ms between requests:

const client = require('flashheart').createClient({
  retries: 10,
  retryTimeout: 500
});

const url = "https://www.example.com/";
client.get(url, (err, body) => {
   if (err) {
      console.error('handle error: ', err);
      return;
   }
   console.log(body);
});
