--- title: refresh description: API Reference for the refresh function. --- `refresh` allows you to refresh the client router from within a [Server Action](/docs/app/getting-started/updating-data). ## Usage `refresh` can **only** be called from within Server Actions. It cannot be used in Route Handlers, Client Components, or any other context. ## Parameters ```tsx refresh(): void; ``` ## Returns `refresh` does not return a value. ## Examples ```ts filename="app/actions.ts" switcher 'use server' import { refresh } from 'next/cache' export async function createPost(formData: FormData) { const title = formData.get('title') const content = formData.get('content') // Create the post in your database const post = await db.post.create({ data: { title, content }, }) refresh() } ``` ```js filename="app/actions.js" switcher 'use server' import { refresh } from 'next/cache' export async function createPost(formData) { const title = formData.get('title') const content = formData.get('content') // Create the post in your database const post = await db.post.create({ data: { title, content }, }) refresh() } ``` ### Error when used outside Server Actions ```ts filename="app/api/posts/route.ts" switcher import { refresh } from 'next/cache' export async function POST() { // This will throw an error refresh() } ```
