Possible piece of an API for a fetch wrapper

object.js

{
  // The response was received, and the data is currently streaming.
  // Note: this can be `true` even when the request fails (if the body of
  // the error is being streamed)
  streaming: <Boolean>,

  // The response has not yet been returned by the server, OR it has been
  // returned and the headers are still streaming (it appears that the headers)
  // are immediately available at the same time that the Response object is
  // made available to you)
  awaiting: <Boolean>,

  // The response succeeded. Equal to (!error && res.ok)
  succeeded: <Boolean>,

  // The response failed for some reason. The opposite of `succeeded`. This
  // includes network errors as well as error status codes.
  // Equal to (error || !res.ok)
  failed: <Boolean>,
