StaleTimes (experimental)

Warning: The staleTimes configuration is an experimental feature. This configuration strategy will likely change in the future.

staleTimes is an experimental feature that allows configuring the invalidation period of the client router cache.

This configuration option is available as of v14.2.0-canary.53.

You can enable this experimental feature & provide custom revalidation times by setting the experimental staleTimes flag:

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    staleTimes: {
      dynamic: 30,
      static: 180,
    },
  },
}
 
module.exports = nextConfig

The static and dynamic properties correspond with the time period (in seconds) based on different types of link prefetching.

• The dynamic property is used when the page is neither statically generated nor fully prefetched (i.e., with prefetch=).
  • Default: 0 seconds (not cached)
• The static property is used for statically generated pages, or when the prefetch prop on Link is set to true, or when calling router.prefetch.
  • Default: 5 minutes

Good to know:

• Loading boundaries are considered reusable for the static period defined in this configuration.
• This doesn't affect partial rendering, meaning shared layouts won't automatically be refetched on every navigation, only the page segment that changes.
• This doesn't change back/forward caching behavior to prevent layout shift and to prevent losing the browser scroll position.
