      bail(new Error('Unauthorized'));
      return;

    return data.substr(0, 500);
  },

    retries: 5,
  }

API

retry(retrier : Function, opts : Object) => Promise
  • The supplied function can be async or not. In other words, it can be a function that returns a Promise or a value.
  • The supplied function receives two parameters
    1. A Function you can invoke to abort the retrying (bail)
    2. A Number identifying the attempt. The absolute first attempt (before any retries) is 1.
  • The opts are passed to node-retry. Read its docs
    • retries: The maximum amount of times to retry the operation. Default is 10.
    • factor: The exponential factor to use. Default is 2.
    • minTimeout: The number of milliseconds before starting the first retry. Default is 1000.
    • maxTimeout: The maximum number of milliseconds between two retries. Default is Infinity.
    • randomize: Randomizes the timeouts by multiplying with a factor between 1 to 2. Default is true.
    • onRetry: an optional Function that is invoked after a new retry is performed. It's passed the Error that triggered it as a parameter.
