onSuccess (required)

This function will be called every time the polling service gets a successful response. You should return true to continue polling and false to stop polling. It has the following signature:

function onSuccess(response) {
  // You can do anything with this response, may be add to an array of some state of your react component
  // return true to continue polling
  // return false to stop polling
}

onFailure (not compulsory field)

This function will be called every time the polling service gets a failure response from the api, it can be 401 or 500 or any failure status code. You can do some cleaning up of your variables or reseting the state here.

function onFailure(error) {
  // You can log this error to some logging service
  // clean up some state and variables.
}
