next-cache-components

To cache specific parts of a Next.js page, enable cacheComponents in next.config and use the use cache directive on individual components. This allows you to selectively cache static or cached segments while keeping other parts of the same route fully dynamic.

The best way to control cache invalidation in Next.js partial prerendering is by leveraging cacheLife and cacheTag. You use cacheLife to define the duration of cached content and cacheTag to selectively invalidate specific cached segments when underlying data changes.

Yes, Next.js 16 supports mixing static, cached, and dynamic content within a single route using Cache Components. By annotating specific components with the use cache directive, you can balance performance and data freshness across complex interfaces like dashboards and feeds.

You should use the use cache directive in React server components when building routes that mix static and dynamic content, such as user panels or feeds. It allows you to selectively prerender expensive segments, reducing server load while preserving necessary interactivity.

To enable Cache Components in Next.js 16, you must toggle the cacheComponents setting in your next.config file. Once enabled, you can progressively annotate pages and components with use cache directives and cacheLife to manage caching behavior.
