```

import { init } from "pagerless/browser";

init({ key: import.meta.env.VITE_PAGERLESS_KEY, service: "web" });
```

## What it catches

- Uncaught errors and unhandled rejections in the page, grouped by path.
- Failing fetch calls (5xx, 429, network) from pagerless 0.2.0.
- Sent when the tab is hidden.

## Questions

### Is it safe to ship the key?

Yes. Ingest keys can only send events. Use a separate key for the browser so you can revoke it alone.
