# showError
> Nuxt provides a quick and simple way to show a full screen error page if needed.
Within the [Nuxt context](/docs/4.x/guide/going-further/nuxt-app#the-nuxt-context) you can use `showError` to show an error.
**Parameters:**
- `error`: `string | Error | Partial<{ cause, data, message, name, stack, status, statusText }>`
```ts
showError('😱 Oh no, an error has been thrown.')
showError({
status: 404,
statusText: 'Page Not Found',
})
```
The error is set in the state using [`useError()`](/docs/4.x/api/composables/use-error) to create a reactive and SSR-friendly shared error state across components.
`showError` calls the `app:error` hook.
