Status: Experimental

Library for configuring retry, concurrency of async operations.

Retry

Utility to configure automatic retries.

Installation

npm install @async-task/retry

Usage

import { retryPolicy, fixedBackoffStrategy } from '@task-runner/retry'

const retry = retryPolicy.config({
  attempts: 3,
  timeout: 10000,
  backoff: fixedBackoffStrategy({ delay: 200, maxDelay: 5000}),
});

const task = () => {
  return fetch('https://example.com/data');
}

const main = async () => {
  try {
    const result = retry.run(task);

    // handle result
  } catch (error) {
    // handle error
  }
}

main();

Retry Config

• attempts: number

  Maximum number of times to retry function.

• timeout?: number

  Overall timeout in milliseconds

• backoff?: Function

  Backoff strategy to use for increasing delay in-between retries. Available strategity are: fixedBackoffStrategy, linearBackoffStrategy, exponentialBackoffStrategy

• jitter?: 'full' | 'none'

  Adds randomness to backoff duration to spread the retries around in time and minimize collisions.
