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