## Installation

npm install popsicle-retry --save
```

## Usage

```js
import { retry } from "popsicle-retry";

const send = retry(transport);
const res = await send(req);

### Methods

- **retry(fn, shouldRetry?)** Wraps a request function with retry support. Accepts a second function that returns a delay, or `-1` (default is `retries()`).
- **retryAllowed(error?, request?)** Check if a request should be retried. Defaults to `5xx` and unavailable errors.
- **retries(count?, isRetryAllowed?)** An exponential back-off function, defaulting to 3 retries.
