Documentation

autoRetry(fn, options) ⇒ function

Higher order function that makes any promise-returning-function retryable with a jitter'd exponential backoff.

// Construct a new function to only retry once
const requestWithRetry = autoRetry(requestPromise, { maxRetries: 1 });


// Set a minimum backoff interval to 2 seconds
const requestWithRetry = autoRetry(requestPromise, { backoffBase: 2000 });
