::note
`refreshNuxtData` re-fetches all data from the server and updates the page as well as invalidates the cache of [`useAsyncData`](/docs/api/composables/use-async-data) , `useLazyAsyncData`, [`useFetch`](/docs/api/composables/use-fetch) and `useLazyFetch`.
::
## Type
```ts
refreshNuxtData(keys?: string | string[])
```
**Parameters:**
* `keys`:
**Type**: `String | String[]`
`refreshNuxtData` accepts a single or an array of strings as `keys` that are used to fetch the data. This parameter is **optional**. All [`useAsyncData`](/docs/api/composables/use-async-data) and [`useFetch`](/docs/api/composables/use-fetch) are re-fetched when no `keys` are specified.
## Refresh All Data
This example below refreshes all data being fetched using [`useAsyncData`](/docs/api/composables/use-async-data) and [`useFetch`](/docs/api/composables/use-fetch) on the current page.
```vue [pages/some-page.vue]
<script setup lang="ts">
const refreshing = ref(false)
const refreshAll = async () => {
refreshing.value = true
try {
await refreshNuxtData()
} finally {
refreshing.value = false
}
}
</script>
<template>
<div>
<button :disabled="refreshing" @click="refreshAll">
Refetch All Data
</button>
</div>
</template>
```
## Refresh Specific Data
This example below refreshes only data where the key matches to `count`.
```vue [pages/some-page.vue]
<script setup lang="ts">
const { pending, data: count } = await useLazyAsyncData('count', () => $fetch('/api/count'))
const refresh = () => refreshNuxtData('count')
</script>
<template>
<div>
{{ pending ? 'Loading' : count }}
</div>
<button @click="refresh">Refresh</button>
</template>
```
