Retry async operations with custom backoff strategies
[work in progress] Wrap an async function with retry logic.
$ npm install retry-on-error
var retry = require'retry-on-error';
- timeout -- a number representing the time in ms to wait between retrys or
a function that accepts the attempt number as its only parameter and
returns the time in ms to wait after that attempt number. Numbers are
use for static timeouts, and functions can be used for custom backoff
strategies. This module also includes functions to create common
backoff strategies. See backoff strategy section below.
- accept -- predicate function that takes the same arguments
as the callback, and returns truthy if the execution should be
accepted as success and falsey if the execution should be
considered a failure/error. The default accept function follows the node
callback pattern where the first parameter to the callback represents
- minTimeout and maxTimtout -- used to coerce the result of the timeout
- maxAttempts -- the maximum number number of attempts before
giving up and returning the last error.
