Retry Utils

This lib aims to apply retry patterns for various needed situations.

Usage

retryPromise - Implements retries for a Promise with exponential backoff. The retryPromise method apply a fuzz factor of 50% in either direction. So if the ideal delay is 1000ms, the actual delay will be randomly chosen between 500ms and 1500ms. Configuration:

retryParameters: {
  action: 'Callback to be executed',
  maxAttempts: 'The maximum number of attempts that should be retried'
  baseDelay: 'The delay before the first retry, in milliseconds',
  backOffFactor: 'The multiplier for successive retry delays'
}

Examples:

retryPromise:

import { retryPromise } from 'retry-utils'

const getSomething = () => {
  return fetch(`http://httpbin.org/status/500`)
    .then((response) => {
      if (response.ok) return response
      throw new Error(response.statusText)
    })
}

let retryParameters: {
  action: getSomething,
  maxAttempts: 5,
  baseDelay: 1000,
  backOffFactor: 3
}

retryPromise(retryParameters)
  .then(() => console.log('Retry success'))
  .catch(() => console.log('Retry error'))
