Next Cache Components
Next Cache Components enable Partial Prerendering in Next.js 16, letting you combine prerendered static content, cached async data, and fresh dynamic sections in a single route. The `use cache` directive marks functions for caching with configurable lifetimes via `cacheLife()`, while `cacheTag()` and `updateTag()` handle invalidation. Replaces the older `experimental.ppr` flag and `unstable_cache()` API.
Next Cache Components lets you mix static, cached, and dynamic content in Next.js 16 routes for better performance.

Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
What is Next Cache Components and how does it improve Next.js performance?
Next Cache Components enable Partial Prerendering in Next.js 16, combining prerendered static content, cached async data, and fresh dynamic sections in a single route. By marking functions with the `use cache` directive, you reduce re-renders and optimize data fetching, significantly improving app performance without manual cache layer setup.
How do you implement next cache components in your Next.js application?
Next Cache Components uses the `use cache` directive to mark functions for caching. Configure cache lifetimes with `cacheLife()`, manage invalidation through `cacheTag()` and `updateTag()`, and combine static prerendered sections with dynamic content in a single route. This replaces the older `experimental.ppr` flag and `unstable_cache()` API.
What is the difference between next cache components and older caching methods?
Next Cache Components modernizes caching in Next.js 16 by replacing `experimental.ppr` and `unstable_cache()`. The new `use cache` directive provides cleaner syntax, configurable cache lifetimes via `cacheLife()`, and tag-based invalidation with `cacheTag()` and `updateTag()`, offering more efficient component-level caching.
How does nextjs caching library handle component memoization and data caching?
Next Cache Components handles both component memoization and data caching through the `use cache` directive. Mark async functions and components for caching, set lifetimes with `cacheLife()`, and invalidate cached data using `cacheTag()` and `updateTag()` for precise control over what stays fresh and what remains cached.
Can Next Cache Components reduce re-renders in React components?
Yes, Next Cache Components reduces re-renders by caching component output and async data fetching. The `use cache` directive prevents unnecessary recalculation of expensive operations, while configurable cache lifetimes ensure fresh data when needed. This cache management approach significantly decreases rendering overhead in complex applications.

Structure caching from the start in Next.js 16+ App Router projects by building a tag registry, revalidation utilities, and data-fetching functions with "use cache" directives. This skill guides you through placing cache logic on data functions rather than pages, wiring mutations to invalidation, and organizing Suspense boundaries for partial prerendering. Includes templates for tags, revalidation handlers, and patterns for personalized content near cache boundaries.
This skill covers 21 rules for implementing Partial Prerendering in Next.js 16 App Router, guiding you through enabling cacheComponents, placing Suspense boundaries, caching with 'use cache', handling runtime APIs, composing pages with parallel streaming, and building forms with mutations. Each rule corrects a specific misconception about the dynamic-by-default rendering model and shows the canonical approach for mixing static chrome with personalized or real-time content.
