		// abort retrying if the resource doesn't exist

## API

### pRetry(input, [options])

Returns a `Promise` that is fulfilled when calling `input` returns a fulfilled promise. If calling `input` returns a rejected promise, `input` is called again until the max retries are reached, it then rejects with the last rejection reason.

It doesn't retry on `TypeError` as that's a user error.

#### input

Type: `Function`

Receives the number of attempts as the first argument and is expected to return a `Promise` or any value.

#### options

Type: `Object`

Options are passed to the [`retry`](https://github.com/tim-kos/node-retry#retryoperationoptions) module.

### pRetry.AbortError(message|error)

Abort retrying and reject the promise.

### message

Type: `string`

Error message.

### error

Type: `Error`

Custom error.
