staleTimes

staleTimes is an experimental feature that enables caching of page segments in the client-side router cache.

You can enable this experimental feature and 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.
