Composable Caching

The 'use cache' directive enables fine-grained caching at the function level. Combined with cacheTag, you can invalidate specific cache entries on demand.

Cached Timestamp

Uses cacheLife("default") preset from next.config.ts. Refresh the page - the timestamp stays the same until cache expires or is revalidated.

Cached Quote

Uses cacheLife("hours") for longer caching. Different cache tags allow independent invalidation.

Innovation distinguishes between a leader and a follower.

How it works

1. Functions with 'use cache' are cached automatically
2. cacheLife() sets how long the cache is valid
3. cacheTag() assigns tags for selective revalidation
4. revalidateTag() invalidates cache entries by tag
