Incremental Static Regeneration

• In this example, three posts fetch data using granular ISR.
• Caches responses are fresh for 100 seconds.
• Try navigating to each post and noting the timestamp of when the page was rendered. Refresh the page after 100 seconds to trigger a revalidation for the next request. Refresh again to see the revalidated page.
• Note that the fetch cache can be persisted across builds.
