# Pagerless for Deno

> One import from npm. Deno gets its own build.

URL: https://pagerless.dev/integrations/deno
Updated: 2026-10-22

## Set up

```ts
import "npm:pagerless/auto";
```

With a package.json, `import "pagerless/auto"` works too.

## What it catches

- Uncaught errors and unhandled rejections.
- Errors from `Deno.serve` handlers, re-thrown unchanged.
- Failing `fetch` calls.
- Sends before the process exits.

## Questions

### Does it work on Deno Deploy?

It uses the same Deno APIs; set `PAGERLESS_KEY` in the project's environment variables.
