This page will guide you through how to create layouts and pages, and link between them.\n\n## Creating a page\n\nA **page** is UI that is rendered on a specific route. To create a page, add a [`page` file](/docs/app/api-reference/file-conventions/page) inside the `app` directory and default export a React component. For example, to create an index page (`/`):\n\n\n\n```tsx filename=\"app/page.tsx\" switcher\nexport default function Page() {\n return

Hello Next.js!

\n}\n```\n\n```jsx filename=\"app/page.js\" switcher\nexport default function Page() {\n return

Hello Next.js!

\n}\n```\n\n## Creating a layout\n\nA layout is UI that is **shared** between multiple pages. On navigation, layouts preserve state, remain interactive, and do not rerender.\n\nYou can define a layout by default exporting a React component from a [`layout` file](/docs/app/api-reference/file-conventions/layout). The component should accept a `children` prop which can be a page or another [layout](#nesting-layouts).\n\nFor example, to create a layout that accepts your index page as child, add a `layout` file inside the `app` directory:\n\n\n\n```tsx filename=\"app/layout.tsx\" switcher\nexport default function DashboardLayout({\n children,\n}: {\n children: React.ReactNode\n}) {\n return (\n \n \n {/* Layout UI */}\n {/* Place children where you want to render a page or nested layout */}\n
{children}
\n \n \n )\n}\n```\n\n```jsx filename=\"app/layout.js\" switcher\nexport default function DashboardLayout({ children }) {\n return (\n \n \n {/* Layout UI */}\n {/* Place children where you want to render a page or nested layout */}\n
{children}
\n \n \n )\n}\n```\n\nThe layout above is called a [root layout](/docs/app/api-reference/file-conventions/layout#root-layout) because it's defined at the root of the `app` directory. The root layout is **required** and must contain `html` and `body` tags.\n\n## Creating a nested route\n\nA nested route is a route composed of multiple URL segments. For example, the `/blog/[slug]` route is composed of three segments:\n\n- `/` (Root Segment)\n- `blog` (Segment)\n- `[slug]` (Leaf Segment)\n\nIn Next.js:\n\n- **Folders** are used to define the route segments that map to URL segments.\n- **Files** (like `page` and `layout`) are used to create UI that is shown for a segment.\n\nTo create nested routes, you can nest folders inside each other. For example, to add a route for `/blog`, create a folder called `blog` in the `app` directory. Then, to make `/blog` publicly accessible, add a `page.tsx` file:\n\n\n\n```tsx filename=\"app/blog/page.tsx\" switcher\n// Dummy imports\nimport { getPosts } from '@/lib/posts'\nimport { Post } from '@/ui/post'\n\nexport default async function Page() {\n const posts = await getPosts()\n\n return (\n
    \n {posts.map((post) => (\n \n ))}\n
\n )\n}\n```\n\n```jsx filename=\"app/blog/page.js\" switcher\n// Dummy imports\nimport { getPosts } from '@/lib/posts'\nimport { Post } from '@/ui/post'\n\nexport default async function Page() {\n const posts = await getPosts()\n\n return (\n
    \n {posts.map((post) => (\n \n ))}\n
\n )\n}\n```\n\nYou can continue nesting folders to create nested routes. For example, to create a route for a specific blog post, create a new `[slug]` folder inside `blog` and add a `page` file:\n\n\n\n```tsx filename=\"app/blog/[slug]/page.tsx\" switcher\nfunction generateStaticParams() {}\n\nexport default function Page() {\n return

Hello, Blog Post Page!

\n}\n```\n\n```jsx filename=\"app/blog/[slug]/page.js\" switcher\nfunction generateStaticParams() {}\n\nexport default function Page() {\n return

Hello, Blog Post Page!

\n}\n```\n\nWrapping a folder name in square brackets (e.g. `[slug]`) creates a [dynamic route segment](/docs/app/api-reference/file-conventions/dynamic-routes) which is used to generate multiple pages from data. e.g. blog posts, product pages, etc.\n\n## Nesting layouts\n\nBy default, layouts in the folder hierarchy are also nested, which means they wrap child layouts via their `children` prop. You can nest layouts by adding `layout` inside specific route segments (folders).\n\nFor example, to create a layout for the `/blog` route, add a new `layout` file inside the `blog` folder.\n\n\n\n```tsx filename=\"app/blog/layout.tsx\" switcher\nexport default function BlogLayout({\n children,\n}: {\n children: React.ReactNode\n}) {\n return
{children}
\n}\n```\n\n```jsx filename=\"app/blog/layout.js\" switcher\nexport default function BlogLayout({ children }) {\n return
{children}
\n}\n```\n\nIf you were to combine the two layouts above, the root layout (`app/layout.js`) would wrap the blog layout (`app/blog/layout.js`), which would wrap the blog (`app/blog/page.js`) and blog post page (`app/blog/[slug]/page.js`).\n\n## Creating a dynamic segment\n\n[Dynamic segments](/docs/app/api-reference/file-conventions/dynamic-routes) allow you to create routes that are generated from data. For example, instead of manually creating a route for each individual blog post, you can create a dynamic segment to generate the routes based on blog post data.\n\nTo create a dynamic segment, wrap the segment (folder) name in square brackets: `[segmentName]`. For example, in the `app/blog/[slug]/page.tsx` route, the `[slug]` is the dynamic segment.\n\n```tsx filename=\"app/blog/[slug]/page.tsx\" switcher\nexport default async function BlogPostPage({\n params,\n}: {\n params: Promise<{ slug: string }>\n}) {\n const { slug } = await params\n const post = await getPost(slug)\n\n return (\n
\n

{post.title}

\n

{post.content}

\n
\n )\n}\n```\n\n```jsx filename=\"app/blog/[slug]/page.js\" switcher\nexport default async function BlogPostPage({ params }) {\n const { slug } = await params\n const post = await getPost(slug)\n\n return (\n

[The static `metadata` object](#static-metadata)\n2. [The dynamic `generateMetadata` function](#generated-metadata)\n3. Special [file conventions](/docs/app/api-reference/file-conventions/metadata) that can be used to add static or dynamically generated [favicons](#favicons) and [OG images](#static-open-graph-images).\n\nWith all the options above, Next.js will automatically generate the relevant `` tags for your page, which can be inspected in the browser's developer tools.\n\nThe `metadata` object and `generateMetadata` function exports are only supported in Server Components.\n\n## Default fields\n\nThere are two default `meta` tags that are always added even if a route doesn't define metadata:\n\n- The [meta charset tag](https://developer.mozilla.org/docs/Web/HTML/Element/meta#attr-charset) sets the character encoding for the website.\n- The [meta viewport tag](https://developer.mozilla.org/docs/Web/HTML/Viewport_meta_tag) sets the viewport width and scale for the website to adjust for different devices.\n\n```html\n\n\n```\n\nThe other metadata fields can be defined with the `Metadata` object (for [static metadata](#static-metadata)) or the `generateMetadata` function (for [generated metadata](#generated-metadata)).\n\n## Static metadata\n\nTo define static metadata, export a [`Metadata` object](/docs/app/api-reference/functions/generate-metadata#metadata-object) from a static [`layout.js`](/docs/app/api-reference/file-conventions/layout) or [`page.js`](/docs/app/api-reference/file-conventions/page) file. For example, to add a title and description to the blog route:\n\n```tsx filename=\"app/blog/layout.tsx\" switcher\nimport type { Metadata } from 'next'\n\nexport const metadata: Metadata = {\n title: 'My Blog',\n description: '...',\n}\n\nexport default function Layout() {}\n```\n\n```jsx filename=\"app/blog/layout.js\" switcher\nexport const metadata = {\n title: 'My Blog',\n description: '...',\n}\n\nexport default function Layout() {}\n```\n\nYou can view a full list of available options, in the [`generateMetadata` documentation](/docs/app/api-reference/functions/generate-metadata#metadata-fields).\n\n## Generated metadata\n\nYou can use [`generateMetadata`](/docs/app/api-reference/functions/generate-metadata) function to `fetch` metadata that depends on data. For example, to fetch the title and description for a specific blog post:\n\n```tsx filename=\"app/blog/[slug]/page.tsx\" switcher\nimport type { Metadata, ResolvingMetadata } from 'next'\n\ntype Props = {\n params: Promise<{ slug: string }>\n searchParams: Promise<{ [key: string]: string | string[] | undefined }>\n}\n\nexport async function generateMetadata(\n { params, searchParams }: Props,\n parent: ResolvingMetadata\n): Promise {\n const slug = (await params).slug\n\n // fetch post information\n const post = await fetch(`https://api.vercel.app/blog/${slug}`).then((res) =>\n res.json()\n )\n\n return {\n title: post.title,\n description: post.description,\n }\n}\n\nexport default function Page({ params, searchParams }: Props) {}\n```\n\n```jsx filename=\"app/blog/[slug]/page.js\" switcher\nexport async function generateMetadata({ params, searchParams }, parent) {\n const slug = (await params).slug\n\n // fetch post information\n const post = await fetch(`https://api.vercel.app/blog/${slug}`).then((res) =>\n res.json()\n )\n\n return {\n title: post.title,\n description: post.description,\n }\n}\n\nexport default function Page({ params, searchParams }) {}\n```\n\n### Streaming metadata\n\nFor dynamically rendered pages, Next.js streams metadata separately, injecting it into the HTML once `generateMetadata` resolves, without blocking UI rendering.\n\nStreaming metadata improves perceived performance by allowing visual content to stream first.\n\nStreaming metadata is **disabled for bots and crawlers** that expect metadata to be in the `` tag (e.g. `Twitterbot`, `Slackbot`, `Bingbot`). These are detected by using the User Agent header from the incoming request.\n\nYou can customize or **disable** streaming metadata completely, with the [`htmlLimitedBots`](/docs/app/api-reference/config/next-config-js/htmlLimitedBots#disabling) option in your Next.js config file.\n\nPrerendered pages don’t use streaming since metadata is resolved at build time.\n\nLearn more about [streaming metadata](/docs/app/api-reference/functions/generate-metadata#streaming-metadata).\n\n### Memoizing data requests\n\nThere may be cases where you need to fetch the **same** data for metadata and the page itself. To avoid duplicate requests, you can use React's [`cache` function](https://react.dev/reference/react/cache) to memoize the return value and only fetch the data once. For example, to fetch the blog post information for both the metadata and the page:\n\n```ts filename=\"app/lib/data.ts\" highlight={5} switcher\nimport { cache } from 'react'\nimport { db } from '@/app/lib/db'\n\n// getPost will be used twice, but execute only once\nexport const getPost = cache(async (slug: string) => {\n const res = await db.query.posts.findFirst({ where: eq(posts.slug, slug) })\n return res\n})\n```\n\n```js filename=\"app/lib/data.js\" highlight={5} switcher\nimport { cache } from 'react'\nimport { db } from '@/app/lib/db'\n\n// getPost will be used twice, but execute only once\nexport const getPost = cache(async (slug) => {\n const res = await db.query.posts.findFirst({ where: eq(posts.slug, slug) })\n return res\n})\n```\n\n```tsx filename=\"app/blog/[slug]/page.tsx\" switcher\nimport { getPost } from '@/app/lib/data'\n\nexport async function generateMetadata({\n params,\n}: {\n params: Promise<{ slug: string }>\n}) {\n const { slug } = await params\n const post = await getPost(slug)\n return {\n title: post.title,\n description: post.description,\n }\n}\n\nexport default async function Page({\n params,\n}: {\n params: Promise<{ slug: string }>\n}) {\n const { slug } = await params\n const post = await getPost(slug)\n return
{post.title}
\n}\n```\n\n```jsx filename=\"app/blog/[slug]/page.js\" switcher\nimport { getPost } from '@/app/lib/data'\n\nexport async function generateMetadata({ params }) {\n const { slug } = await params\n const post = await getPost(slug)\n return {\n title: post.title,\n description: post.description,\n }\n}\n\nexport default async function Page({ params }) {\n const { slug } = await params\n const post = await getPost(slug)\n return
{post.title}
\n}\n```\n\n## File-based metadata\n\nThe following special files are available for metadata:\n\n- [favicon.ico, apple-icon.jpg, and icon.jpg](/docs/app/api-reference/file-conventions/metadata/app-icons)\n- [opengraph-image.jpg and twitter-image.jpg](/docs/app/api-reference/file-conventions/metadata/opengraph-image)\n- [robots.txt](/docs/app/api-reference/file-conventions/metadata/robots)\n- [sitemap.xml](/docs/app/api-reference/file-conventions/metadata/sitemap)\n\nYou can use these for static metadata, or you can programmatically generate these files with code.\n\n## Favicons\n\nFavicons are small icons that represent your site in bookmarks and search results. To add a favicon to your application, create a `favicon.ico` and add to the root of the app folder.\n\n **Good to know**: HTML is also generated for the initial visit.\n\n### Prefetching\n\nPrefetching is the process of loading a route in the background before the user navigates to it. This makes navigation between routes in your application feel instant, because by the time a user clicks on a link, the data to render the next route is already available client side.\n\nNext.js automatically prefetches routes linked with the [`` component](/docs/app/api-reference/components/link) when they enter the user's viewport.\n\n```tsx filename=\"app/layout.tsx\" switcher\nimport Link from 'next/link'\n\nexport default function Layout({ children }: { children: React.ReactNode }) {\n return (\n \n \n \n {children}\n \n \n )\n}\n```\n\n```jsx filename=\"app/layout.js\" switcher\nimport Link from 'next/link'\n\nexport default function Layout({ children }) {\n return (\n \n \n \n {children}\n \n \n )\n}\n```\n\nHow much of the route is prefetched depends on whether it's static or dynamic:\n\n- **Static Route**: the full route is prefetched.\n- **Dynamic Route**: prefetching is skipped, or the route is partially prefetched if [`loading.tsx`](/docs/app/api-reference/file-conventions/loading) is present.\n\nBy skipping or partially prefetching dynamic routes, Next.js avoids unnecessary work on the server for routes the users may never visit. However, waiting for a server response before navigation can give the users the impression that the app is not responding.\n\n\n\nTo improve the navigation experience to dynamic routes, you can use [streaming](#streaming).\n\n### Streaming\n\nStreaming allows the server to send parts of a dynamic route to the client as soon as they're ready, rather than waiting for the entire route to be rendered. This means users see something sooner, even if parts of the page are still loading. See the [Streaming guide](/docs/app/guides/streaming) for a deep dive into how streaming works in Next.js.\n\nFor dynamic routes, it means they can be **partially prefetched**. That is, shared layouts and loading skeletons can be requested ahead of time.\n\n\n\nTo use streaming, create a `loading.tsx` in your route folder:\n\n\n\n```tsx filename=\"app/dashboard/loading.tsx\" switcher\nexport default function Loading() {\n // Add fallback UI that will be shown while the route is loading.\n return \n}\n```\n\n```jsx filename=\"app/dashboard/loading.js\" switcher\nexport default function Loading() {\n // Add fallback UI that will be shown while the route is loading.\n return \n}\n```\n\nBehind the scenes, Next.js will automatically wrap the `page.tsx` contents in a `` boundary. The prefetched fallback UI will be shown while the route is loading, and swapped for the actual content once ready.\n\n> **Good to know**: You can also use [``](https://react.dev/reference/react/Suspense) to create loading UI for nested components.\n\nBenefits of `loading.tsx`:\n\n- Immediate navigation and visual feedback for the user.\n- Shared layouts remain interactive and navigation is interruptible.\n- Improved Core Web Vitals: [TTFB](https://web.dev/articles/ttfb), [FCP](https://web.dev/articles/fcp), and [TTI](https://web.dev/articles/tti).\n\nTo further improve the navigation experience, Next.js performs a [client-side transition](#client-side-transitions) with the `` component.\n\n### Client-side transitions\n\nTraditionally, navigation to a server-rendered page triggers a full page load. This clears state, resets scroll position, and blocks interactivity.\n\nNext.js avoids this with client-side transitions using the `` component. Instead of reloading the page, it updates the content dynamically by:\n\n- Keeping any shared layouts and UI.\n- Replacing the current page with the prefetched loading state or a new page if available.\n\nClient-side transitions are what makes a server-rendered apps _feel_ like client-rendered apps. And when paired with [prefetching](#prefetching) and [streaming](#streaming), it enables fast transitions, even for dynamic routes.\n\nNext.js also handles [scrolling to the top of the page](/docs/app/api-reference/components/link#scroll) during client-side transitions. If content scrolls behind a sticky or fixed header after navigation, you can fix this with CSS [`scroll-padding-top`](/docs/app/api-reference/components/link#scroll-offset-with-sticky-headers).\n\n## What can make transitions slow?\n\nThese Next.js optimizations make navigation fast and responsive. However, under certain conditions, transitions can still _feel_ slow. Here are some common causes and how to improve the user experience:\n\n### Dynamic routes without `loading.tsx`\n\nWhen navigating to a dynamic route, the client must wait for the server response before showing the result. This can give the users the impression that the app is not responding.\n\nWe recommend adding `loading.tsx` to dynamic routes to enable partial prefetching, trigger immediate navigation, and display a loading UI while the route renders.\n\n```tsx filename=\"app/blog/[slug]/loading.tsx\" switcher\nexport default function Loading() {\n return \n}\n```\n\n```jsx filename=\"app/blog/[slug]/loading.js\" switcher\nexport default function Loading() {\n","exit_code":0,"status":"completed"}} +{"type":"item.started","item":{"id":"item_6","type":"command_execution","command":"/bin/bash -lc \"printf '%s\\\\n' '--- app router migration headings ---'; rg -n '\"'^#{1,3} |Root layout|Metadata|Link|_app|_document|Step'\"' node_modules/next/dist/docs/01-app/02-guides/migrating/app-router-migration.md | head -100; printf '%s\\\\n' '--- relevant migration section ---'; sed -n '210,500p' node_modules/next/dist/docs/01-app/02-guides/migrating/app-router-migration.md; printf '%s\\\\n' '--- source files ---'; for f in pages/_app.tsx pages/_document.tsx pages/index.tsx pages/about.tsx next.config.ts tsconfig.json; do echo \\\"### \"'$f\"; sed -n '\"'1,260p' \\\"\"'$f\"; done'","aggregated_output":"","exit_code":null,"status":"in_progress"}} +{"type":"item.completed","item":{"id":"item_6","type":"command_execution","command":"/bin/bash -lc \"printf '%s\\\\n' '--- app router migration headings ---'; rg -n '\"'^#{1,3} |Root layout|Metadata|Link|_app|_document|Step'\"' node_modules/next/dist/docs/01-app/02-guides/migrating/app-router-migration.md | head -100; printf '%s\\\\n' '--- relevant migration section ---'; sed -n '210,500p' node_modules/next/dist/docs/01-app/02-guides/migrating/app-router-migration.md; printf '%s\\\\n' '--- source files ---'; for f in pages/_app.tsx pages/_document.tsx pages/index.tsx pages/about.tsx next.config.ts tsconfig.json; do echo \\\"### \"'$f\"; sed -n '\"'1,260p' \\\"\"'$f\"; done'","aggregated_output":"--- app router migration headings ---\n13:## Upgrading\n15:### Node.js Version\n19:### Next.js Version\n39:### ESLint Version\n61:## Next Steps\n65:- [Upgrade new features](#upgrading-new-features): A guide to help you upgrade to new features such as the improved Image and Link Components.\n68:## Upgrading New Features\n72:Upgrading to Next.js 13 does **not** require using the App Router.

The UI preferences stored in cookies stream in at request time.\n316-\n317:Reading `cookies()` here doesn't opt-in the whole route into dynamic rendering, the way the previous rendering model did. The Suspense boundary provides fallback UI where the runtime access streams, while static and cached content still ship in the initial HTML.\n318-\n319:Just as `` contains async access, an **error boundary** contains failures: wrap them around a subtree that might error during rendering. Use [`catchError`](/docs/app/api-reference/functions/catchError) for component-level boundaries, or the [`error.js`](/docs/app/api-reference/file-conventions/error) file convention for route-level boundaries.\n320-\n321:As you build, consider that inside [`generateMetadata`](/docs/app/api-reference/functions/generate-metadata#with-cache-components) and [`generateViewport`](/docs/app/api-reference/functions/generate-viewport#with-cache-components), uncached fetches or runtime data access surface the same insights and errors as in your page, guiding you to the rendering you intend.

One set of elements disappears, another appears, with no visual connection between them. A user selects a photo thumbnail to view it in detail on another page. They are the same image, but nothing on screen communicates that.\n\nApps that need these transitions typically rely on complex animation libraries that manage mount/unmount lifecycles, track element positions across routes, and coordinate timing manually, to animate how elements enter, exit, and move between states.\n\nReact's `` component integrates with the browser's [View Transitions API](https://developer.mozilla.org/en-US/docs/Web/API/View_Transition_API) to handle this declaratively. You name the elements that should persist, and the browser animates between their old and new positions.\n\nThis guide walks through four patterns that cover the most common cases: morphing shared elements, animating loading states, adding directional navigation, and crossfading content within the same route.\n\n## Example\n\nAs an example, we'll build a photography gallery called _Frames_.\n\nWe'll start by morphing a thumbnail into a hero image (shared elements), then animate the loading skeleton into real content (Suspense reveals), add directional slides for forward and back navigation (route transitions), and finish with crossfades for switching between photographer tabs (same-route transitions).\n\nYou can find the resources used in this example here:\n\n- [Demo](https://react-view-transitions-demo.labs.vercel.dev)\n- [Code](https://github.com/vercel-labs/react-view-transitions-demo)\n\nBefore starting, enable view transitions in your Next.js config:\n\n```ts filename=\"next.config.ts\"\nimport type { NextConfig } from 'next'\n\nconst nextConfig: NextConfig = {\n experimental: {\n viewTransition: true,\n },\n}\n\nexport default nextConfig\n```\n\nApp Router uses [React canary releases](https://react.dev/blog/2023/05/03/react-canaries), which contain all stable React 19 changes as well as newer features like `ViewTransition`. You do not need to install `react@canary` yourself.\n\n> [!NOTE]\n> The View Transitions API is supported in all major browsers, though some animations may behave differently in Safari. Without browser support, your application works normally, the transitions simply do not animate.\n\nThen import the `ViewTransition` component from React:\n\n```tsx\nimport { ViewTransition } from 'react'\n```\n\n`` animations are activated by [Transitions](https://react.dev/reference/react/useTransition), [``](https://react.dev/reference/react/Suspense), and [`useDeferredValue`](https://react.dev/reference/react/useDeferredValue). Regular `setState` calls do not trigger them. In Next.js, route navigations are transitions, so `` animations activate automatically during navigation.\n\n### Step 1: Morph a thumbnail into a hero image\n\nThe gallery displays photos in a grid. Clicking a photo opens a detail page with a larger version of the same image. Without transitions, the thumbnail disappears and the hero appears. Nothing connects them visually. The user has to scan the detail page to confirm they clicked the right photo.\n\nIn motion design, when an object persists across a cut, it communicates continuity. The viewer understands they are looking at the same thing, not a replacement. This is the most important transition pattern: **shared element morphing**.\n\nWrap both the grid thumbnail and the detail hero in `` with the same `name`:\n\n```tsx filename=\"components/photo-grid.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\nimport Link from 'next/link'\n\nfunction PhotoGrid({ photos }) {\n return (\n
\n {photos.map((photo) => (\n \n \n {photo.title}\n \n \n ))}\n
\n )\n}\n```\n\n```tsx filename=\"app/photo/[id]/photo-content.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\n\nasync function PhotoContent({ id }) {\n const photo = await getPhoto(id)\n\n return (\n \n {photo.title}\n \n )\n}\n```\n\nThe `name` prop creates identity. React finds elements with the same name on the old and new pages, then animates between their size and position automatically. No additional props are needed for the morph to work.\n\nIf we click a thumbnail now, the image scales and repositions from its grid cell to the hero slot. Navigating back reverses the morph. The user sees one object moving, not two objects swapping.\n\n#### Customizing the morph animation\n\nThe morph works without any CSS. To customize it, add `share=\"morph\"`. This assigns the `morph` class to the view transition, which you can target with CSS pseudo-elements. For example, to soften the morph mid-flight with a [`blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur) keyframe:\n\n```tsx\n\n {photo.title}\n\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(.morph) {\n animation-duration: 400ms;\n}\n::view-transition-image-pair(.morph) {\n animation-name: via-blur;\n}\n@keyframes via-blur {\n 30% {\n filter: blur(3px);\n }\n}\n```\n\nThe blur hides pixel-level interpolation artifacts during the transition. At 400ms, the morph is slow enough to register but fast enough to feel direct.\n\n### Step 2: Animate loading states with Suspense reveals\n\nThe photo detail page loads its content asynchronously. While data is in flight, a Suspense boundary shows a skeleton. When the data resolves, the skeleton is replaced by the real content.\n\nWithout a transition, the swap is instant. The skeleton vanishes and the content pops in.\n\nIn motion design, vertical direction encodes hierarchy. Content sliding up communicates arrival. Content sliding down communicates departure. The pair together creates a handoff: the placeholder yields to the real thing.\n\nWrap the Suspense fallback in a `ViewTransition` with an exit animation, and the content in a `ViewTransition` with an enter animation:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function PhotoPage({ params }) {\n const { id } = await params\n\n return (\n \n \n
\n }\n >\n \n \n \n
\n )\n}\n```\n\nThe `default=\"none\"` prop prevents this `ViewTransition` from animating during unrelated transitions, like the shared element morph from Step 1. Without it, every transition on the page would trigger every `ViewTransition`'s animation.\n\nThe CSS animations use asymmetric timing. The exit is fast (150ms). The enter is slower (210ms) and delayed until the exit completes:\n\n```css filename=\"app/globals.css\"\n:root {\n --duration-exit: 150ms;\n --duration-enter: 210ms;\n}\n\n::view-transition-old(.slide-down) {\n animation:\n var(--duration-exit) ease-out both fade reverse,\n var(--duration-exit) ease-out both slide-y reverse;\n}\n::view-transition-new(.slide-up) {\n animation:\n var(--duration-enter) ease-in var(--duration-exit) both fade,\n 400ms ease-in both slide-y;\n}\n\n@keyframes fade {\n from {\n filter: blur(3px);\n opacity: 0;\n }\n to {\n filter: blur(0);\n opacity: 1;\n }\n}\n@keyframes slide-y {\n from {\n transform: translateY(10px);\n }\n to {\n transform: translateY(0);\n }\n}\n```\n\nThe asymmetry is deliberate. Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n
\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n
\n
\n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n--- link transitionTypes ---\n }}\n >\n Dashboard\n \n )\n}\n```\n\n```jsx filename=\"app/page.js\" switcher\nimport Link from 'next/link'\n\nexport default function Page() {\n return (\n {\n // Only executes during SPA navigation\n console.log('Navigating...')\n\n // Optionally prevent navigation\n // e.preventDefault()\n }}\n >\n Dashboard\n \n )\n}\n```\n\n> **Good to know**: While `onClick` and `onNavigate` may seem similar, they serve different purposes. `onClick` executes for all click events, while `onNavigate` only runs during client-side navigation. Some key differences:\n>\n> - When using modifier keys (`Ctrl`/`Cmd` + Click), `onClick` executes but `onNavigate` doesn't since Next.js prevents default navigation for new tabs.\n> - External URLs won't trigger `onNavigate` since it's only for client-side and same-origin navigations.\n> - Links with the `download` attribute will work with `onClick` but not `onNavigate` since the browser will treat the linked URL as a download.\n\n### `transitionTypes`\n\n\n\nA list of transition types to apply to the navigation.

React finds elements with the same name on the old and new pages, then animates between their size and position automatically. No additional props are needed for the morph to work.\n\nIf we click a thumbnail now, the image scales and repositions from its grid cell to the hero slot. Navigating back reverses the morph. The user sees one object moving, not two objects swapping.\n\n#### Customizing the morph animation\n\nThe morph works without any CSS. To customize it, add `share=\"morph\"`. This assigns the `morph` class to the view transition, which you can target with CSS pseudo-elements. For example, to soften the morph mid-flight with a [`blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur) keyframe:\n\n```tsx\n\n {photo.title}\n\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(.morph) {\n animation-duration: 400ms;\n}\n::view-transition-image-pair(.morph) {\n animation-name: via-blur;\n}\n@keyframes via-blur {\n 30% {\n filter: blur(3px);\n }\n}\n```\n\nThe blur hides pixel-level interpolation artifacts during the transition. At 400ms, the morph is slow enough to register but fast enough to feel direct.\n\n### Step 2: Animate loading states with Suspense reveals\n\nThe photo detail page loads its content asynchronously. While data is in flight, a Suspense boundary shows a skeleton. When the data resolves, the skeleton is replaced by the real content.\n\nWithout a transition, the swap is instant. The skeleton vanishes and the content pops in.\n\nIn motion design, vertical direction encodes hierarchy. Content sliding up communicates arrival. Content sliding down communicates departure. The pair together creates a handoff: the placeholder yields to the real thing.\n\nWrap the Suspense fallback in a `ViewTransition` with an exit animation, and the content in a `ViewTransition` with an enter animation:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function PhotoPage({ params }) {\n const { id } = await params\n\n return (\n \n \n \n }\n >\n \n \n \n \n )\n}\n```\n\nThe `default=\"none\"` prop prevents this `ViewTransition` from animating during unrelated transitions, like the shared element morph from Step 1. Without it, every transition on the page would trigger every `ViewTransition`'s animation.\n\nThe CSS animations use asymmetric timing. The exit is fast (150ms). The enter is slower (210ms) and delayed until the exit completes:\n\n```css filename=\"app/globals.css\"\n:root {\n --duration-exit: 150ms;\n --duration-enter: 210ms;\n}\n\n::view-transition-old(.slide-down) {\n animation:\n var(--duration-exit) ease-out both fade reverse,\n var(--duration-exit) ease-out both slide-y reverse;\n}\n::view-transition-new(.slide-up) {\n animation:\n var(--duration-enter) ease-in var(--duration-exit) both fade,\n 400ms ease-in both slide-y;\n}\n\n@keyframes fade {\n from {\n filter: blur(3px);\n opacity: 0;\n }\n to {\n filter: blur(0);\n opacity: 1;\n }\n}\n@keyframes slide-y {\n from {\n transform: translateY(10px);\n }\n to {\n transform: translateY(0);\n }\n}\n```\n\nThe asymmetry is deliberate. Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n\n--- remaining guide ---\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n \n \n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n\n--- files ---\n 1\timport type { Metadata } from 'next'\n 2\timport './globals.css'\n 3\t\n 4\texport const metadata: Metadata = {\n 5\t title: 'Product Gallery',\n 6\t description: 'A simple product gallery',\n 7\t}\n 8\t\n 9\texport default function RootLayout({\n 10\t children,\n 11\t}: Readonly<{\n 12\t children: React.ReactNode\n 13\t}>) {\n 14\t return (\n 15\t \n 16\t {children}\n 17\t \n 18\t )\n 19\t}\n 1\timport { Suspense } from 'react'\n 2\timport { ProductGrid } from './ProductGrid'\n 3\timport { ProductGridSkeleton } from './ProductSkeleton'\n 4\t\n 5\texport default function Home() {\n 6\t return (\n 7\t

The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\nnode_modules/@types/react/ts5.0/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/ts5.0/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/ts5.0/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/ts5.0/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/ts5.0/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/@types/react/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/next/dist/client/link.d.ts:99: * About\nnode_modules/next/dist/client/link.d.ts:102: transitionTypes?: string[];\nnode_modules/next/dist/client/app-dir/link.d.ts:180: * About\nnode_modules/next/dist/client/app-dir/link.d.ts:183: transitionTypes?: string[];\nnode_modules/next/dist/client/components/app-router-instance.d.ts:28:export declare function dispatchNavigateAction(href: string, navigateType: NavigateAction['navigateType'], scrollBehavior: ScrollBehavior, linkInstanceRef: LinkInstance | null, transitionTypes: string[] | undefined, prefetchIntent: RouterTransitionPrefetchIntent | null): void;\nnode_modules/next/dist/shared/lib/app-router-context.shared-runtime.d.ts:14: transitionTypes?: string[];\n","exit_code":0,"status":"completed"}} +{"type":"item.started","item":{"id":"item_9","type":"command_execution","command":"/bin/bash -lc \"sed -n '325,350p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; sed -n '35,115p' node_modules/@types/react/canary.d.ts; cat node_modules/@types/react/package.json | sed -n '1,100p'\"","aggregated_output":"","exit_code":null,"status":"in_progress"}} +{"type":"item.completed","item":{"id":"item_9","type":"command_execution","command":"/bin/bash -lc \"sed -n '325,350p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; sed -n '35,115p' node_modules/@types/react/canary.d.ts; cat node_modules/@types/react/package.json | sed -n '1,100p'\"","aggregated_output":"Directional slides simulate physical movement across the viewport.

A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\ndeclare module \".\" {\n export function

One set of elements disappears, another appears, with no visual connection between them. A user selects a photo thumbnail to view it in detail on another page. They are the same image, but nothing on screen communicates that.\n\nApps that need these transitions typically rely on complex animation libraries that manage mount/unmount lifecycles, track element positions across routes, and coordinate timing manually, to animate how elements enter, exit, and move between states.\n\nReact's `` component integrates with the browser's [View Transitions API](https://developer.mozilla.org/en-US/docs/Web/API/View_Transition_API) to handle this declaratively. You name the elements that should persist, and the browser animates between their old and new positions.\n\nThis guide walks through four patterns that cover the most common cases: morphing shared elements, animating loading states, adding directional navigation, and crossfading content within the same route.\n\n## Example\n\nAs an example, we'll build a photography gallery called _Frames_.\n\nWe'll start by morphing a thumbnail into a hero image (shared elements), then animate the loading skeleton into real content (Suspense reveals), add directional slides for forward and back navigation (route transitions), and finish with crossfades for switching between photographer tabs (same-route transitions).\n\nYou can find the resources used in this example here:\n\n- [Demo](https://react-view-transitions-demo.labs.vercel.dev)\n- [Code](https://github.com/vercel-labs/react-view-transitions-demo)\n\nBefore starting, enable view transitions in your Next.js config:\n\n```ts filename=\"next.config.ts\"\nimport type { NextConfig } from 'next'\n\nconst nextConfig: NextConfig = {\n experimental: {\n viewTransition: true,\n },\n}\n\nexport default nextConfig\n```\n\nApp Router uses [React canary releases](https://react.dev/blog/2023/05/03/react-canaries), which contain all stable React 19 changes as well as newer features like `ViewTransition`. You do not need to install `react@canary` yourself.\n\n> [!NOTE]\n> The View Transitions API is supported in all major browsers, though some animations may behave differently in Safari. Without browser support, your application works normally, the transitions simply do not animate.\n\nThen import the `ViewTransition` component from React:\n\n```tsx\nimport { ViewTransition } from 'react'\n```\n\n`` animations are activated by [Transitions](https://react.dev/reference/react/useTransition), [``](https://react.dev/reference/react/Suspense), and [`useDeferredValue`](https://react.dev/reference/react/useDeferredValue). Regular `setState` calls do not trigger them. In Next.js, route navigations are transitions, so `` animations activate automatically during navigation.\n\n### Step 1: Morph a thumbnail into a hero image\n\nThe gallery displays photos in a grid. Clicking a photo opens a detail page with a larger version of the same image. Without transitions, the thumbnail disappears and the hero appears. Nothing connects them visually. The user has to scan the detail page to confirm they clicked the right photo.\n\nIn motion design, when an object persists across a cut, it communicates continuity. The viewer understands they are looking at the same thing, not a replacement. This is the most important transition pattern: **shared element morphing**.\n\nWrap both the grid thumbnail and the detail hero in `` with the same `name`:\n\n```tsx filename=\"components/photo-grid.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\nimport Link from 'next/link'\n\nfunction PhotoGrid({ photos }) {\n return (\n
\n {photos.map((photo) => (\n \n \n {photo.title}\n \n \n ))}\n
\n )\n}\n```\n\n```tsx filename=\"app/photo/[id]/photo-content.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\n\nasync function PhotoContent({ id }) {\n const photo = await getPhoto(id)\n\n return (\n \n {photo.title}\n \n )\n}\n```\n\nThe `name` prop creates identity. React finds elements with the same name on the old and new pages, then animates between their size and position automatically. No additional props are needed for the morph to work.\n\nIf we click a thumbnail now, the image scales and repositions from its grid cell to the hero slot. Navigating back reverses the morph. The user sees one object moving, not two objects swapping.\n\n#### Customizing the morph animation\n\nThe morph works without any CSS. To customize it, add `share=\"morph\"`. This assigns the `morph` class to the view transition, which you can target with CSS pseudo-elements. For example, to soften the morph mid-flight with a [`blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur) keyframe:\n\n```tsx\n\n {photo.title}\n\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(.morph) {\n animation-duration: 400ms;\n}\n::view-transition-image-pair(.morph) {\n animation-name: via-blur;\n}\n@keyframes via-blur {\n 30% {\n filter: blur(3px);\n }\n}\n```\n\nThe blur hides pixel-level interpolation artifacts during the transition. At 400ms, the morph is slow enough to register but fast enough to feel direct.\n\n### Step 2: Animate loading states with Suspense reveals\n\nThe photo detail page loads its content asynchronously. While data is in flight, a Suspense boundary shows a skeleton. When the data resolves, the skeleton is replaced by the real content.\n\nWithout a transition, the swap is instant. The skeleton vanishes and the content pops in.\n\nIn motion design, vertical direction encodes hierarchy. Content sliding up communicates arrival. Content sliding down communicates departure. The pair together creates a handoff: the placeholder yields to the real thing.\n\nWrap the Suspense fallback in a `ViewTransition` with an exit animation, and the content in a `ViewTransition` with an enter animation:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function PhotoPage({ params }) {\n const { id } = await params\n\n return (\n \n \n
\n }\n >\n \n \n \n
\n )\n}\n```\n\nThe `default=\"none\"` prop prevents this `ViewTransition` from animating during unrelated transitions, like the shared element morph from Step 1. Without it, every transition on the page would trigger every `ViewTransition`'s animation.\n\nThe CSS animations use asymmetric timing. The exit is fast (150ms). The enter is slower (210ms) and delayed until the exit completes:\n\n```css filename=\"app/globals.css\"\n:root {\n --duration-exit: 150ms;\n --duration-enter: 210ms;\n}\n\n::view-transition-old(.slide-down) {\n animation:\n var(--duration-exit) ease-out both fade reverse,\n var(--duration-exit) ease-out both slide-y reverse;\n}\n::view-transition-new(.slide-up) {\n animation:\n var(--duration-enter) ease-in var(--duration-exit) both fade,\n 400ms ease-in both slide-y;\n}\n\n@keyframes fade {\n from {\n filter: blur(3px);\n opacity: 0;\n }\n to {\n filter: blur(0);\n opacity: 1;\n }\n}\n@keyframes slide-y {\n from {\n transform: translateY(10px);\n }\n to {\n transform: translateY(0);\n }\n}\n```\n\nThe asymmetry is deliberate. Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n
\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n
\n
\n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n--- link transitionTypes ---\n }}\n >\n Dashboard\n \n )\n}\n```\n\n```jsx filename=\"app/page.js\" switcher\nimport Link from 'next/link'\n\nexport default function Page() {\n return (\n {\n // Only executes during SPA navigation\n console.log('Navigating...')\n\n // Optionally prevent navigation\n // e.preventDefault()\n }}\n >\n Dashboard\n \n )\n}\n```\n\n> **Good to know**: While `onClick` and `onNavigate` may seem similar, they serve different purposes. `onClick` executes for all click events, while `onNavigate` only runs during client-side navigation. Some key differences:\n>\n> - When using modifier keys (`Ctrl`/`Cmd` + Click), `onClick` executes but `onNavigate` doesn't since Next.js prevents default navigation for new tabs.\n> - External URLs won't trigger `onNavigate` since it's only for client-side and same-origin navigations.\n> - Links with the `download` attribute will work with `onClick` but not `onNavigate` since the browser will treat the linked URL as a download.\n\n### `transitionTypes`\n\n\n\nA list of transition types to apply to the navigation.

One set of elements disappears, another appears, with no visual connection between them. A user selects a photo thumbnail to view it in detail on another page. They are the same image, but nothing on screen communicates that.\n\nApps that need these transitions typically rely on complex animation libraries that manage mount/unmount lifecycles, track element positions across routes, and coordinate timing manually, to animate how elements enter, exit, and move between states.\n\nReact's `` component integrates with the browser's [View Transitions API](https://developer.mozilla.org/en-US/docs/Web/API/View_Transition_API) to handle this declaratively. You name the elements that should persist, and the browser animates between their old and new positions.\n\nThis guide walks through four patterns that cover the most common cases: morphing shared elements, animating loading states, adding directional navigation, and crossfading content within the same route.\n\n## Example\n\nAs an example, we'll build a photography gallery called _Frames_.\n\nWe'll start by morphing a thumbnail into a hero image (shared elements), then animate the loading skeleton into real content (Suspense reveals), add directional slides for forward and back navigation (route transitions), and finish with crossfades for switching between photographer tabs (same-route transitions).\n\nYou can find the resources used in this example here:\n\n- [Demo](https://react-view-transitions-demo.labs.vercel.dev)\n- [Code](https://github.com/vercel-labs/react-view-transitions-demo)\n\nBefore starting, enable view transitions in your Next.js config:\n\n```ts filename=\"next.config.ts\"\nimport type { NextConfig } from 'next'\n\nconst nextConfig: NextConfig = {\n experimental: {\n viewTransition: true,\n },\n}\n\nexport default nextConfig\n```\n\nApp Router uses [React canary releases](https://react.dev/blog/2023/05/03/react-canaries), which contain all stable React 19 changes as well as newer features like `ViewTransition`. You do not need to install `react@canary` yourself.\n\n> [!NOTE]\n> The View Transitions API is supported in all major browsers, though some animations may behave differently in Safari. Without browser support, your application works normally, the transitions simply do not animate.\n\nThen import the `ViewTransition` component from React:\n\n```tsx\nimport { ViewTransition } from 'react'\n```\n\n`` animations are activated by [Transitions](https://react.dev/reference/react/useTransition), [``](https://react.dev/reference/react/Suspense), and [`useDeferredValue`](https://react.dev/reference/react/useDeferredValue). Regular `setState` calls do not trigger them. In Next.js, route navigations are transitions, so `` animations activate automatically during navigation.\n\n### Step 1: Morph a thumbnail into a hero image\n\nThe gallery displays photos in a grid. Clicking a photo opens a detail page with a larger version of the same image. Without transitions, the thumbnail disappears and the hero appears. Nothing connects them visually. The user has to scan the detail page to confirm they clicked the right photo.\n\nIn motion design, when an object persists across a cut, it communicates continuity. The viewer understands they are looking at the same thing, not a replacement. This is the most important transition pattern: **shared element morphing**.\n\nWrap both the grid thumbnail and the detail hero in `` with the same `name`:\n\n```tsx filename=\"components/photo-grid.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\nimport Link from 'next/link'\n\nfunction PhotoGrid({ photos }) {\n return (\n
\n {photos.map((photo) => (\n \n \n {photo.title}\n \n \n ))}\n
\n )\n}\n```\n\n```tsx filename=\"app/photo/[id]/photo-content.tsx\"\nimport { ViewTransition } from 'react'\nimport Image from 'next/image'\n\nasync function PhotoContent({ id }) {\n const photo = await getPhoto(id)\n\n return (\n \n {photo.title}\n \n )\n}\n```\n\nThe `name` prop creates identity. React finds elements with the same name on the old and new pages, then animates between their size and position automatically. No additional props are needed for the morph to work.\n\nIf we click a thumbnail now, the image scales and repositions from its grid cell to the hero slot. Navigating back reverses the morph. The user sees one object moving, not two objects swapping.\n\n#### Customizing the morph animation\n\nThe morph works without any CSS. To customize it, add `share=\"morph\"`. This assigns the `morph` class to the view transition, which you can target with CSS pseudo-elements. For example, to soften the morph mid-flight with a [`blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur) keyframe:\n\n```tsx\n\n {photo.title}\n\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(.morph) {\n animation-duration: 400ms;\n}\n::view-transition-image-pair(.morph) {\n animation-name: via-blur;\n}\n@keyframes via-blur {\n 30% {\n filter: blur(3px);\n }\n}\n```\n\nThe blur hides pixel-level interpolation artifacts during the transition. At 400ms, the morph is slow enough to register but fast enough to feel direct.\n\n### Step 2: Animate loading states with Suspense reveals\n\nThe photo detail page loads its content asynchronously. While data is in flight, a Suspense boundary shows a skeleton. When the data resolves, the skeleton is replaced by the real content.\n\nWithout a transition, the swap is instant. The skeleton vanishes and the content pops in.\n\nIn motion design, vertical direction encodes hierarchy. Content sliding up communicates arrival. Content sliding down communicates departure. The pair together creates a handoff: the placeholder yields to the real thing.\n\nWrap the Suspense fallback in a `ViewTransition` with an exit animation, and the content in a `ViewTransition` with an enter animation:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function PhotoPage({ params }) {\n const { id } = await params\n\n return (\n \n \n
\n }\n >\n \n \n \n
\n )\n}\n```\n\nThe `default=\"none\"` prop prevents this `ViewTransition` from animating during unrelated transitions, like the shared element morph from Step 1. Without it, every transition on the page would trigger every `ViewTransition`'s animation.\n\nThe CSS animations use asymmetric timing. The exit is fast (150ms). The enter is slower (210ms) and delayed until the exit completes:\n\n```css filename=\"app/globals.css\"\n:root {\n --duration-exit: 150ms;\n --duration-enter: 210ms;\n}\n\n::view-transition-old(.slide-down) {\n animation:\n var(--duration-exit) ease-out both fade reverse,\n var(--duration-exit) ease-out both slide-y reverse;\n}\n::view-transition-new(.slide-up) {\n animation:\n var(--duration-enter) ease-in var(--duration-exit) both fade,\n 400ms ease-in both slide-y;\n}\n\n@keyframes fade {\n from {\n filter: blur(3px);\n opacity: 0;\n }\n to {\n filter: blur(0);\n opacity: 1;\n }\n}\n@keyframes slide-y {\n from {\n transform: translateY(10px);\n }\n to {\n transform: translateY(0);\n }\n}\n```\n\nThe asymmetry is deliberate. Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n
\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n
\n \n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n--- link transitionTypes ---\n }}\n >\n Dashboard\n \n )\n}\n```\n\n```jsx filename=\"app/page.js\" switcher\nimport Link from 'next/link'\n\nexport default function Page() {\n return (\n {\n // Only executes during SPA navigation\n console.log('Navigating...')\n\n // Optionally prevent navigation\n // e.preventDefault()\n }}\n >\n Dashboard\n \n )\n}\n```\n\n> **Good to know**: While `onClick` and `onNavigate` may seem similar, they serve different purposes. `onClick` executes for all click events, while `onNavigate` only runs during client-side navigation.

React finds elements with the same name on the old and new pages, then animates between their size and position automatically. No additional props are needed for the morph to work.\n\nIf we click a thumbnail now, the image scales and repositions from its grid cell to the hero slot. Navigating back reverses the morph. The user sees one object moving, not two objects swapping.\n\n#### Customizing the morph animation\n\nThe morph works without any CSS. To customize it, add `share=\"morph\"`. This assigns the `morph` class to the view transition, which you can target with CSS pseudo-elements. For example, to soften the morph mid-flight with a [`blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur) keyframe:\n\n```tsx\n\n {photo.title}\n\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(.morph) {\n animation-duration: 400ms;\n}\n::view-transition-image-pair(.morph) {\n animation-name: via-blur;\n}\n@keyframes via-blur {\n 30% {\n filter: blur(3px);\n }\n}\n```\n\nThe blur hides pixel-level interpolation artifacts during the transition. At 400ms, the morph is slow enough to register but fast enough to feel direct.\n\n### Step 2: Animate loading states with Suspense reveals\n\nThe photo detail page loads its content asynchronously. While data is in flight, a Suspense boundary shows a skeleton. When the data resolves, the skeleton is replaced by the real content.\n\nWithout a transition, the swap is instant. The skeleton vanishes and the content pops in.\n\nIn motion design, vertical direction encodes hierarchy. Content sliding up communicates arrival. Content sliding down communicates departure. The pair together creates a handoff: the placeholder yields to the real thing.\n\nWrap the Suspense fallback in a `ViewTransition` with an exit animation, and the content in a `ViewTransition` with an enter animation:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function PhotoPage({ params }) {\n const { id } = await params\n\n return (\n \n \n \n }\n >\n \n \n \n \n )\n}\n```\n\nThe `default=\"none\"` prop prevents this `ViewTransition` from animating during unrelated transitions, like the shared element morph from Step 1. Without it, every transition on the page would trigger every `ViewTransition`'s animation.\n\nThe CSS animations use asymmetric timing. The exit is fast (150ms). The enter is slower (210ms) and delayed until the exit completes:\n\n```css filename=\"app/globals.css\"\n:root {\n --duration-exit: 150ms;\n --duration-enter: 210ms;\n}\n\n::view-transition-old(.slide-down) {\n animation:\n var(--duration-exit) ease-out both fade reverse,\n var(--duration-exit) ease-out both slide-y reverse;\n}\n::view-transition-new(.slide-up) {\n animation:\n var(--duration-enter) ease-in var(--duration-exit) both fade,\n 400ms ease-in both slide-y;\n}\n\n@keyframes fade {\n from {\n filter: blur(3px);\n opacity: 0;\n }\n to {\n filter: blur(0);\n opacity: 1;\n }\n}\n@keyframes slide-y {\n from {\n transform: translateY(10px);\n }\n to {\n transform: translateY(0);\n }\n}\n```\n\nThe asymmetry is deliberate. Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n\n--- remaining guide ---\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n \n \n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n\n--- files ---\n 1\timport type { Metadata } from 'next'\n 2\timport './globals.css'\n 3\t\n 4\texport const metadata: Metadata = {\n 5\t title: 'Product Gallery',\n 6\t description: 'A simple product gallery',\n 7\t}\n 8\t\n 9\texport default function RootLayout({\n 10\t children,\n 11\t}: Readonly<{\n 12\t children: React.ReactNode\n 13\t}>) {\n 14\t return (\n 15\t \n 16\t {children}\n 17\t \n 18\t )\n 19\t}\n 1\timport { Suspense } from 'react'\n 2\timport { ProductGrid } from './ProductGrid'\n 3\timport { ProductGridSkeleton } from './ProductSkeleton'\n 4\t\n 5\texport default function Home() {\n 6\t return (\n 7\t

\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\n ::view-transition-old(*),\n ::view-transition-new(*),\n ::view-transition-group(*) {\n animation-duration: 0s !important;\n animation-delay: 0s !important;\n }\n}\n```\n\nWithout animation, content swaps instantly, which is the browser's default behavior. A more refined approach would preserve crossfades and opacity transitions while removing positional movement. See [\"No Motion Isn't Always prefers-reduced-motion\"](https://css-tricks.com/nuking-motion-with-prefers-reduced-motion/) for more on this.\n\n### Step 4: Crossfade content within the same route\n\nThe gallery has a photographer section with tabs. Each tab shows a different photographer's photos, but the route structure is the same: `/collection/[slug]`. Clicking between tabs does not feel like navigating to a new page. It feels like switching content within the same container.\n\nA directional slide would be wrong here. Slides communicate \"going to a new place.\" A crossfade communicates \"same place, different content.\" The container persists (continuity), only the grid inside changes (swap).\n\nUse a `ViewTransition` with `key` set to the current slug. When the key changes, React triggers a transition between the old and new content:\n\n```tsx filename=\"app/collection/[slug]/page.tsx\"\nimport { Suspense, ViewTransition } from 'react'\n\nexport default async function CollectionPage({ params }) {\n const { slug } = await params\n\n return (\n }>\n \n \n \n \n )\n}\n```\n\nThe `share=\"auto\"` and `enter=\"auto\"` props tell React to use its default crossfade animation. The `name` prop gives the container an identity so React knows what to animate. The `key={slug}` change is what triggers the transition.\n\nIf we click between photographer tabs, the grid crossfades. The tab bar and surrounding layout do not move. Only the photo grid transitions between states.\n\n## Next steps\n\nYou now know how to use view transitions to communicate meaning during navigation. Shared elements communicate continuity across routes. Suspense reveals animate loading handoffs. Directional slides encode navigation history. Crossfades signal content changes within the same location.\n\nEach pattern answers a different question for the user:\n\n| Pattern | What it communicates |\n| ---------------------- | ------------------------------- |\n| Shared element (morph) | \"Same thing, going deeper\" |\n| Suspense reveal | \"Data loaded\" |\n| Directional slide | \"Going forward / coming back\" |\n| Same-route crossfade | \"Same place, different content\" |\n\nFor API details and more patterns:\n\n- [View transition configuration](/docs/app/api-reference/config/next-config-js/viewTransition)\n- [Link `transitionTypes` prop](/docs/app/api-reference/components/link#transitiontypes)\n- [`useRouter`](/docs/app/api-reference/functions/use-router), which also supports `transitionTypes` in `push()` and `replace()`\n- [React `ViewTransition` component](https://react.dev/reference/react/ViewTransition)\n- [Complete CSS from this guide](https://github.com/vercel-labs/react-view-transitions-demo/blob/main/src/app/globals.css) — all keyframes and view transition rules in one file\n\n--- files ---\n 1\timport type { Metadata } from 'next'\n 2\timport './globals.css'\n 3\t\n 4\texport const metadata: Metadata = {\n 5\t title: 'Product Gallery',\n 6\t description: 'A simple product gallery',\n 7\t}\n 8\t\n 9\texport default function RootLayout({\n 10\t children,\n 11\t}: Readonly<{\n 12\t children: React.ReactNode\n 13\t}>) {\n 14\t return (\n 15\t \n 16\t {children}\n 17\t \n 18\t )\n 19\t}\n 1\timport { Suspense } from 'react'\n 2\timport { ProductGrid } from './ProductGrid'\n 3\timport { ProductGridSkeleton } from './ProductSkeleton'\n 4\t\n 5\texport default function Home() {\n 6\t return (\n 7\t

Old content should leave quickly so it does not compete for attention. New content should arrive more gently so the user has time to register it. The `var(--duration-exit)` delay on the enter animation means the new content waits for the old content to finish leaving before it appears.\n\nIf we refresh the page, the skeleton slides down and fades out, and a moment later the real content slides up and fades in.\n\n### Step 3: Add directional motion for navigation\n\nThe gallery now has morphing images and animated loading states. But navigating between pages still has no directional signal. Forward and back navigations look identical. The user cannot tell from the animation whether they moved deeper into the app or returned to a previous page.\n\nIn film and animation, horizontal direction encodes spatial position. Moving left means progressing forward (like turning a page in a left-to-right language). Moving right means going back. This convention is so ingrained that violating it feels disorienting.\n\nUse the `transitionTypes` prop on `` to tag forward navigations:\n\n```tsx filename=\"components/photo-grid.tsx\"\n\n {/* photo thumbnail */}\n\n```\n\nThe same pattern works for any navigation within the app. For example, previous/next arrows on a photo detail page can use `nav-back` and `nav-forward` to animate in the corresponding direction.\n\nFor links that return the user to a previous page, use `nav-back`:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n ← Gallery\n\n```\n\nThe transition type is not automatic. You decide which links are \"forward\" and which are \"back\" based on your app's navigation hierarchy.\n\nThen wrap page content in a `ViewTransition` that maps transition types to directional animations:\n\n```tsx filename=\"app/photo/[id]/page.tsx\"\n\n {/* page content */}\n\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n>\n> - When using modifier keys (`Ctrl`/`Cmd` + Click), `onClick` executes but `onNavigate` doesn't since Next.js prevents default navigation for new tabs.\n> - External URLs won't trigger `onNavigate` since it's only for client-side and same-origin navigations.\n> - Links with the `download` attribute will work with `onClick` but not `onNavigate` since the browser will treat the linked URL as a download.\n\n### `transitionTypes`\n\n\n\nA list of transition types to apply to the navigation.

When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play.

This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\nnode_modules/@types/react/ts5.0/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/ts5.0/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/ts5.0/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/ts5.0/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/ts5.0/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/@types/react/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/next/dist/client/link.d.ts:99: * About\nnode_modules/next/dist/client/link.d.ts:102: transitionTypes?: string[];\nnode_modules/next/dist/client/app-dir/link.d.ts:180: * About\nnode_modules/next/dist/client/app-dir/link.d.ts:183: transitionTypes?: string[];\nnode_modules/next/dist/client/components/app-router-instance.d.ts:28:export declare function dispatchNavigateAction(href: string, navigateType: NavigateAction['navigateType'], scrollBehavior: ScrollBehavior, linkInstanceRef: LinkInstance | null, transitionTypes: string[] | undefined, prefetchIntent: RouterTransitionPrefetchIntent | null): void;\nnode_modules/next/dist/shared/lib/app-router-context.shared-runtime.d.ts:14: transitionTypes?: string[];\n", + "exitCode": 0 + }, + "success": true + }, + "raw": { + "type": "item.completed", + "item": { + "id": "item_8", + "type": "command_execution", + "command": "/bin/bash -lc \"sed -n '245,330p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; rg -n \\\"interface ViewTransition|type ViewTransition|ViewTransitionProps|transitionTypes\\\" node_modules/@types/react node_modules/next/dist -g '*.d.ts' | sed -n '1,160p'\"", + "aggregated_output": " {/* page content */}\n
\n```\n\nThe `enter` and `exit` props accept an object keyed by transition type. When a navigation carries the `nav-forward` type, the exit animation slides old content left and the enter animation slides new content in from the right. The `default: \"none\"` ensures that transitions without a type (like initial page loads) produce no animation.\n\nThe CSS for directional slides:\n\n```css filename=\"app/globals.css\"\n::view-transition-old(.nav-forward) {\n --slide-offset: -60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-forward) {\n --slide-offset: 60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n::view-transition-old(.nav-back) {\n --slide-offset: 60px;\n animation:\n 150ms ease-in both fade reverse,\n 400ms ease-in-out both slide reverse;\n}\n::view-transition-new(.nav-back) {\n --slide-offset: -60px;\n animation:\n 210ms ease-out 150ms both fade,\n 400ms ease-in-out both slide;\n}\n\n@keyframes slide {\n from {\n translate: var(--slide-offset);\n }\n to {\n translate: 0;\n }\n}\n```\n\nThe 60px offset is enough to communicate direction without making the user track a fast-moving element across the screen.\n\n#### Anchoring the header\n\nDuring directional slides, the header should not move. A sliding header breaks the user's spatial anchor. They need one fixed reference point to understand that the _content_ moved, not the entire viewport.\n\nAssign the header a `viewTransitionName` and suppress its animation in CSS:\n\n```tsx filename=\"components/header.tsx\"\n
\n {/* navigation links */}\n
\n```\n\n```css filename=\"app/globals.css\"\n::view-transition-group(site-header) {\n animation: none;\n z-index: 100;\n}\n::view-transition-old(site-header) {\n display: none;\n}\n::view-transition-new(site-header) {\n animation: none;\n}\n```\n\nThe `display: none` on the old snapshot prevents a flash where both old and new headers are briefly visible. The `z-index: 100` ensures the header renders above the sliding content.\n\nIf we navigate forward to a photo, content slides left. If we click the \"← Gallery\" link (tagged with `nav-back`), content slides right. The header stays fixed throughout both transitions.\n\nBrowser-initiated back navigations (the back button or swipe gestures) do not carry a transition type, so the directional slide does not play. The shared element morph from Step 1 still applies if both pages have matching `name` props.\n\n#### Respecting reduced motion\n\nDirectional slides simulate physical movement across the viewport. This is the most common trigger for motion sensitivity. Morphs, reveals, and crossfades carry less risk since they affect smaller areas or rely on opacity rather than position.\n\nThe simplest approach is to disable all animation durations:\n\n```css filename=\"app/globals.css\"\n@media (prefers-reduced-motion: reduce) {\nnode_modules/@types/react/ts5.0/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/ts5.0/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/ts5.0/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/ts5.0/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/ts5.0/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/ts5.0/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/@types/react/experimental.d.ts:142: interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:39: export interface ViewTransitionInstance {\nnode_modules/@types/react/canary.d.ts:41: * The {@link ViewTransitionProps name} that was used in the corresponding {@link ViewTransition} component or `\"auto\"` if the `name` prop was omitted.\nnode_modules/@types/react/canary.d.ts:46: export type ViewTransitionClassPerType = Record<\"default\" | (string & {}), \"none\" | \"auto\" | (string & {})>;\nnode_modules/@types/react/canary.d.ts:47: export type ViewTransitionClass = ViewTransitionClassPerType | ViewTransitionClassPerType[string];\nnode_modules/@types/react/canary.d.ts:49: export interface ViewTransitionProps {\nnode_modules/@types/react/canary.d.ts:109: export const ViewTransition: ExoticComponent;\nnode_modules/next/dist/client/link.d.ts:99: * About\nnode_modules/next/dist/client/link.d.ts:102: transitionTypes?: string[];\nnode_modules/next/dist/client/app-dir/link.d.ts:180: * About\nnode_modules/next/dist/client/app-dir/link.d.ts:183: transitionTypes?: string[];\nnode_modules/next/dist/client/components/app-router-instance.d.ts:28:export declare function dispatchNavigateAction(href: string, navigateType: NavigateAction['navigateType'], scrollBehavior: ScrollBehavior, linkInstanceRef: LinkInstance | null, transitionTypes: string[] | undefined, prefetchIntent: RouterTransitionPrefetchIntent | null): void;\nnode_modules/next/dist/shared/lib/app-router-context.shared-runtime.d.ts:14: transitionTypes?: string[];\n", + "exit_code": 0, + "status": "completed" + } + } + }, + { + "type": "tool_call", + "tool": { + "name": "shell", + "originalName": "command_execution", + "args": { + "command": "/bin/bash -lc \"sed -n '325,350p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; sed -n '35,115p' node_modules/@types/react/canary.d.ts; cat node_modules/@types/react/package.json | sed -n '1,100p'\"", + "_extractedCommand": "/bin/bash -lc \"sed -n '325,350p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; sed -n '35,115p' node_modules/@types/react/canary.d.ts; cat node_modules/@types/react/package.json | sed -n '1,100p'\"" + } + }, + "raw": { + "type": "item.started", + "item": { + "id": "item_9", + "type": "command_execution", + "command": "/bin/bash -lc \"sed -n '325,350p' node_modules/next/dist/docs/01-app/02-guides/view-transitions.md; sed -n '35,115p' node_modules/@types/react/canary.d.ts; cat node_modules/@types/react/package.json | sed -n '1,100p'\"", + "aggregated_output": "", + "exit_code": null, + "status": "in_progress" + } + } + }, + { + "type": "tool_result", + "tool": { + "name": "shell", + "originalName": "command_execution", + "result": { + "output": "Directional slides simulate physical movement across the viewport.
