useError

Usage

The useError composable returns the global Nuxt error that is being handled and is available on both client and server. It provides a reactive, SSR-friendly error state across your app.

const error = useError()

You can use this composable in your components, pages, or plugins to access or react to the current Nuxt error.

Type

interface NuxtError<DataT = unknown> {
  statusCode: number
  statusMessage: string
  message: string
  data?: DataT
  error?: true
}

export const useError: () => Ref<NuxtError | undefined>

Parameters

This composable does not take any parameters.

Return Values

Returns a Ref containing the current Nuxt error (or undefined if there is no error). The error object is reactive and will update automatically when the error state changes.

Example

<script setup lang="ts">
const error = useError()

if (error.value) {
  console.error('Nuxt error:', error.value)
}
</script>
