# refreshCookie > Refresh useCookie values manually when a cookie has changed 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/app.vue] ``` Since [Nuxt v3.12.0](https://github.com/nuxt/nuxt/releases/tag/v3.12.0), the experimental `cookieStore` option is enabled by default. It automatically refreshes the `useCookie` value when cookies change in the browser. ## Type ```ts [Signature] export function refreshCookie (name: string): void ``` --- - [Source](https://github.com/nuxt/nuxt/blob/main/packages/nuxt/src/app/composables/cookie.ts)
