This module can only be imported in service workers.



```js
// @noErrors
import { self } from '$app/service-worker';
```

## self

The execution context of a service worker. This export exists to make it easier to
use service workers with the correct types, provided the importing module is governed
by a `tsconfig.json` that extends [`$app/tsconfig/service-worker`](/docs/kit/$app-tsconfig-service-worker).
