function useQueryClient(id): QueryClient;

Retrieves the QueryClient installed by VueQueryPlugin, via Vue's inject. Must be called inside setup() or another function that supports an injection context.

Parameters

id

string = ''

The queryClientKey passed to VueQueryPlugin — only needed when multiple QueryClients are installed in the same app.

Returns

QueryClient

Throws

If called outside an injection context, or if no QueryClient was installed via VueQueryPlugin.

Example

<script setup lang="ts">
import { useQueryClient } from '@tanstack/vue-query'

const queryClient = useQueryClient()

function invalidate() {
  queryClient.invalidateQueries({ queryKey: ['todos'] })
}
</script>
