# Pagerless for Remix and React Router

> Export handleError from the server entry. Shopify apps built on the Remix or React Router template work the same way.

## Set up

```bash
npm i pagerless
```

```ts
export { handleError } from "pagerless/remix";
```

```ts
export { handleError } from "pagerless/react-router";
```

## What it catches

- Errors in loaders, actions and rendering.
- Skips aborted requests and thrown 4xx responses.
- Reports 5xx and crashes only, never 4xx, and leaves the response, logs and error exactly as they were.
- On Node it also starts the SDK: uncaught errors and unhandled rejections, status and latency per route, failing outbound calls (Stripe, OpenAI, Supabase and others named), a heartbeat every 60 seconds and a deploy marker.

## Questions

### Does connect recognise Shopify apps?

Yes. When it finds `@shopify/shopify-app-*` it labels the service a Shopify app and makes the same change.
