revalidate (route segment config)

Sets the default ISR revalidation interval for a route segment.

Since Next 13 (App Router) Spec ↗

Syntax

export const revalidate = false | 0 | number

Returns

number | false — Seconds before the cache is considered stale.

Examples

// Revalidate the whole page at most every hour (ISR)
export const revalidate = 3600

export default async function Page() {
  const posts = await getPosts()
  return <PostList posts={posts} />
}

// Disable caching for this segment
export const revalidate = 0

Notes

`false` (default) caches indefinitely until manually revalidated; a number sets a time-based revalidation in seconds (Incremental Static Regeneration); `0` opts out of caching entirely. A `fetch`'s own `next.revalidate` can be shorter but not longer than the segment value. Exported from `layout.js`/`page.js`/`route.js`.
