A simple promise retry implementation that will retry a promise X times before rejecting.
Works with any compliant promise library in Node or the browser;
npm install --save retryable-promise
You pass in a function that returns a promise as the first argument and it will retry it up to 3 times until failing. It returns a promise that you can chain from like normal.
You can also optionally pass in an options object as the second argument. It accepts a maxRetry key to alter how many times it will retry the promise before failing. By default, a retry will be attempted immediately however, you can use the timeout key with a value of milliseconds to wait before retrying.
For example, to retry a promise up to 5 times and wait 1 second between each attempt:
return retryablePromise(yourPromise(), {
maxRetries: 5,
timeout: 1000
});
