cache-components

To use use cache and cacheTag in Next.js server components, enable the cacheComponents flag and apply the cache directive to your functions. You then assign cacheTag labels to manage data invalidation and cacheLife to control how long the cached results persist.

Partial Prerendering (PPR) in Next.js is a caching mechanism that combines static page shells with dynamically rendered components. You need PPR to optimize rendering performance and improve responsiveness across routes by proactively caching frequently rendered server components.

You invalidate cached data in Next.js Cache Components by using tag-based invalidation. By assigning specific cacheTag values to your cached server components, you can selectively purge and refresh cached data to ensure data consistency when underlying sources update.

No, you do not need external libraries to enable cacheComponents in your Next.js project. You can adopt standard Next.js tooling and implement cache patterns like use cache and cacheLife natively once the feature is enabled in your next.config file.

cacheLife controls caching durations for Next.js server routes by defining the lifetime of cached data. When applied alongside the use cache directive, it dictates exactly how long server component results persist before expiring, allowing fine-grained performance optimization.

Next.js cache components are limited to server components and routes, requiring the cacheComponents flag in next.config. If not working, verify you are using standard Next.js tooling without unsupported external data fetching libraries that bypass the use cache directive.
