Could you explain why #73 amd #69 were linked here? They seem to be about setting a request timeout, a time period after which the request should be abandoned, like the XMLHttpRequest timeout. I don't think integrating a "retry" package will help with that.

I think that .retry and .timeout options should be added together to be honest.

(async () => {
  const frisbee = new Frisbee({
    // ...
    timeout: 10000, // 10 seconds
    retry: 0 // 0 = infinite retries
  });

  // could also use `.timeout` and `.retry` methods to set on a per-request basis
  const response = await frisbee.get('/').timeout(3000).retry(3);
}());

Sure, makes sense to use them together like that. Do I have it correct though that actually adding a timeout wouldn't require a retry package and it could be used without retries?

[niftylettuce]

Correct @kasbah, but in an ideal world we want to retry X number of times after Y number of timeout seconds per retry.
