Automatically add exponential retry abilities to any function that returns a promise, only rejecting after the retries fail.
$ npm install auto-retryconst requestPromise = require('request-promise');
const autoRetry = require('auto-retry');
// Construct a new function with automatic retry capabilities
const requestWithRetry = autoRetry(requestPromise);
// Make a request
requestWithRetry('http://www.vimeo.com')
.then((response) => {
// Process html as usual
})
.catch((error) => {
// Only called after 3 failed attempts
});Higher order function that makes any promise-returning-function retryable with a jitter'd exponential backoff.
