### Cache Components (Next.js 16+)

Cache Components enable Partial Prerendering (PPR) - mix static, cached, and dynamic content in a single route.

### Enable Cache Components

// next.config.ts
import type { NextConfig } from 'next'

const nextConfig: NextConfig = {
  cacheComponents: true,
}

export default nextConfig

This replaces the old experimental.ppr flag.

### Three Content Types

With Cache Components enabled, content falls into three categories:

### 1. Static (Auto-Prerendered)

Synchronous code, imports, pure computations - prerendered at build time:

export default function Page() {
  return (
    <header>
      <h1>Our Blog</h1>  {/* Static - instant */}
      <nav>...</nav>
    </header>
  )
}

### 2. Cached (use cache)

Async data that doesn't need fresh fetches every request:

async function BlogPosts() {
  'use cache'
  cacheLife('hours')

  const posts = await db.posts.findMany()
  return <PostList posts={posts} />
}

### 3. Dynamic (Suspense)

Runtime data that must be fresh - wrap in Suspense:

import { Suspense } from 'react'

export default function Page() {
  return (
    <>
      <BlogPosts />  {/* Cached */}

      <Suspense fallback={<p>Loading...</p>}>
        <UserPreferences />  {/* Dynamic - streams in */}
      </Suspense>
    </>
  )
}

async function UserPreferences() {
  const theme = (await cookies()).get('theme')?.value
  return <p>Theme: {theme}</p>
}

### File Level

'use cache'

export default async function Page() {
  // Entire page is cached
  const data = await fetchData()
  return <div>{data}</div>
}

### Component Level

export async function CachedComponent() {
  'use cache'
  const data = await fetchData()
  return <div>{data}</div>
}

### Function Level

export async function getData() {
  'use cache'
  return db.query('SELECT * FROM posts')
}

### Built-in Profiles

'use cache'                    // Default: 5m stale, 15m revalidate

'use cache: remote'           // Platform-provided cache (Redis, KV)

'use cache: private'          // For compliance, allows runtime APIs

### cacheLife() - Custom Lifetime

import { cacheLife } from 'next/cache'

async function getData() {
  'use cache'
  cacheLife('hours')  // Built-in profile
  return fetch('/api/data')
}

Built-in profiles: 'default', 'minutes', 'hours', 'days', 'weeks', 'max'

### Inline Configuration

async function getData() {
  'use cache'
  cacheLife({
    stale: 3600,      // 1 hour - serve stale while revalidating
    revalidate: 7200, // 2 hours - background revalidation interval
    expire: 86400,    // 1 day - hard expiration
  })
  return fetch('/api/data')
}

### cacheTag() - Tag Cached Content

import { cacheTag } from 'next/cache'

async function getProducts() {
  'use cache'
  cacheTag('products')
  return db.products.findMany()
}

async function getProduct(id: string) {
  'use cache'
  cacheTag('products', \`product-${id}\`)
  return db.products.findUnique({ where: { id } })
}

### updateTag() - Immediate Invalidation

Use when you need the cache refreshed within the same request:

'use server'

import { updateTag } from 'next/cache'

export async function updateProduct(id: string, data: FormData) {
  await db.products.update({ where: { id }, data })
  updateTag(\`product-${id}\`)  // Immediate - same request sees fresh data
}

### revalidateTag() - Background Revalidation

Use for stale-while-revalidate behavior:

'use server'

import { revalidateTag } from 'next/cache'

export async function createPost(data: FormData) {
  await db.posts.create({ data })
  revalidateTag('posts')  // Background - next request sees fresh data
}

### Runtime Data Constraint

Cannot access cookies(), headers(), or searchParams inside use cache.

### Solution: Pass as Arguments

// Wrong - runtime API inside use cache
async function CachedProfile() {
  'use cache'
  const session = (await cookies()).get('session')?.value  // Error!
  return <div>{session}</div>
}

// Correct - extract outside, pass as argument
async function ProfilePage() {
  const session = (await cookies()).get('session')?.value
  return <CachedProfile sessionId={session} />
}

async function CachedProfile({ sessionId }: { sessionId: string }) {
  'use cache'
  // sessionId becomes part of cache key automatically
  const data = await fetchUserData(sessionId)
  return <div>{data.name}</div>
}

### Exception: use cache: private

For compliance requirements when you can't refactor:

async function getData() {
  'use cache: private'
  const session = (await cookies()).get('session')?.value  // Allowed
  return fetchData(session)
}

### Cache Key Generation

Cache keys are automatic based on:

Build ID - invalidates all caches on deploy
Function ID - hash of function location
Serializable arguments - props become part of key
Closure variables - outer scope values included

async function Component({ userId }: { userId: string }) {
  const getData = async (filter: string) => {
    'use cache'
    // Cache key = userId (closure) + filter (argument)
    return fetch(\`/api/users/${userId}?filter=${filter}\`)
  }
  return getData('active')
}

### Complete Example

import { Suspense } from 'react'
import { cookies } from 'next/headers'
import { cacheLife, cacheTag } from 'next/cache'

export default function DashboardPage() {
  return (
    <>
      {/* Static shell - instant from CDN */}
      <header><h1>Dashboard</h1></header>
      <nav>...</nav>

      {/* Cached - fast, revalidates hourly */}
      <Stats />

      {/* Dynamic - streams in with fresh data */}
      <Suspense fallback={<NotificationsSkeleton />}>
        <Notifications />
      </Suspense>
    </>
  )
}

async function Stats() {
  'use cache'
  cacheLife('hours')
  cacheTag('dashboard-stats')

  const stats = await db.stats.aggregate()
  return <StatsDisplay stats={stats} />
}

async function Notifications() {
  const userId = (await cookies()).get('userId')?.value
  const notifications = await db.notifications.findMany({
    where: { userId, read: false }
  })
  return <NotificationList items={notifications} />
}

### Migration from Previous Versions

Old ConfigReplacementexperimental.pprcacheComponents: truedynamic = 'force-dynamic'Remove (default behavior)dynamic = 'force-static''use cache' + cacheLife('max')revalidate = NcacheLife({ revalidate: N })unstable_cache()'use cache' directive

### Migrating unstable_cache to use cache

unstable_cache has been replaced by the use cache directive in Next.js 16. When cacheComponents is enabled, convert unstable_cache calls to use cache functions:

Before (unstable_cache):

import { unstable_cache } from 'next/cache'

const getCachedUser = unstable_cache(
  async (id) => getUser(id),
  ['my-app-user'],
  {
    tags: ['users'],
    revalidate: 60,
  }
)

export default async function Page({ params }: { params: Promise<{ id: string }> }) {
  const { id } = await params
  const user = await getCachedUser(id)
  return <div>{user.name}</div>
}

After (use cache):

import { cacheLife, cacheTag } from 'next/cache'

async function getCachedUser(id: string) {
  'use cache'
  cacheTag('users')
  cacheLife({ revalidate: 60 })
  return getUser(id)
}

export default async function Page({ params }: { params: Promise<{ id: string }> }) {
  const { id } = await params
  const user = await getCachedUser(id)
  return <div>{user.name}</div>
}

Key differences:

No manual cache keys - use cache generates keys automatically from function arguments and closures. The keyParts array from unstable_cache is no longer needed.
Tags - Replace options.tags with cacheTag() calls inside the function.
Revalidation - Replace options.revalidate with cacheLife({ revalidate: N }) or a built-in profile like cacheLife('minutes').
Dynamic data - unstable_cache did not support cookies() or headers() inside the callback. The same restriction applies to use cache, but you can use 'use cache: private' if needed.

### Limitations

Edge runtime not supported - requires Node.js
Static export not supported - needs server
Non-deterministic values (Math.random(), Date.now()) execute once at build time inside use cache

For request-time randomness outside cache:

import { connection } from 'next/server'

async function DynamicContent() {
  await connection()  // Defer to request time
  const id = crypto.randomUUID()  // Different per request
  return <div>{id}</div>
}
