This utility is available since [Nuxt v3.10](/blog/v3-10).
|
|
::
|
|
|
|
## Purpose
|
|
|
|
The `refreshCookie` function is designed to refresh cookie value returned by `useCookie`.
|
|
|
|
This is useful for updating the `useCookie` ref when we know the new cookie value has been set in the browser.
|
|
|
|
## Usage
|
|
|
|
```vue [app.vue]
|
|
<script setup lang="ts">
|
|
const tokenCookie = useCookie('token')
|
|
|
|
const login = async (username, password) => {
|
|
const token = await $fetch('/api/token', { ... }) // Sets `token` cookie on response
|
|
refreshCookie('token')
|
|
}
|
|
|
|
const loggedIn = computed(() => !!tokenCookie.value)
|
|
</script>
|
|
```
|
|
|
|
::callout{to="/docs/guide/going-further/experimental-features#cookiestore"}
|
|
You can enable experimental `cookieStore` option to automatically refresh `useCookie` value when cookie changes in the browser.
|

|
|
|
|
## Type
|
|
|
|
```ts
|
|
refreshCookie(name: string): void
|
|
```
