@codewell/retry

Recursively retries to call a function if the execution fails.

Installation

npm install @codewell/retry

Basic Usage

import retry from '@codewell/retry';

retry(fetch)("http://example.com")
  .then(data => {
    // Do something with the returned data,
    // in this case an http response,
    // from fetch("http://example.com")
  })
  .catch(error => {
    // This is where we end up if all retries
    // failed to execute
  });

retry will make the function call fetch("http://example.com"). If it fails, retry will try to call fetch("http://example.com") for 3 times (default) before it gives up.

Configuration

retry is also configurable with options:

import retry from '@codewell/retry';

const options = {
  // Number of tries before we stop
  // Default value: 3
  maxTries: 3,

  // A function that returns number
  // of milliseconds to wait before
  // next execution
  // Default function: (retryCount) => 1000
  backoffStrategy: (retryCount) => 1000,

  // Parameter from 0-2 that sets
  // how much logging retry should do.
  // Default value: 1
  logLevel: 1,
};

retry(fetch, options)("http://example.com");

The options object is optional to pass. All options are optional to configure.
