util-retry

A thin and lightweight utilty to wrap an async function and makes it retryable. If all retires failed, the last attampt error will be sent back.

Example #1

const retry = require('util-retry');

var request = retry(api); // try calling api function 3 times

request({...options as required by the api}, callback );

Other Examples

const retry = require('util-retry');

// try calling api function 5 times
var request = retry(5, api);

// same as above
var request = retry({times: 5}, api);

// set 10 seconds to wait between retries.
var request = retry({times: 5, wait: 10000}, api);

retry([options], task)

• options: <Number>|<Object>

  • times: Unsigned int. Retry limitation. Default: 3.
  • wait : Milliseconds. The interval time to wait between retries. Default: 0

  If options is a number, it means times

• task

  Normal async function, nodejs style callback is always the last argument.
