Overview

Guide for implementing smooth, native-feeling animations using React's View Transition API (`<ViewTransition>` component, `addTransitionType`, and CSS view transition pseudo-elements). Use this skill whenever the user wants to add page transitions, animate route changes, create shared element animations, animate enter/exit of components, animate list reorder, implement directional (forward/back) navigation animations, or integrate view transitions in Next.js. Also use when the user mentions view transitions, `startViewTransition`, `ViewTransition`, transition types, or asks about animating between UI states in React without third-party animation libraries.

React View Transitions

Animate between UI states using the browser's native document.startViewTransition. Declare what with <ViewTransition>, trigger when with startTransition / useDeferredValue / Suspense, control how with CSS classes. Unsupported browsers skip animations gracefully.

When to Animate

Every <ViewTransition> should communicate a spatial relationship or continuity. If you can't articulate what it communicates, don't add it.

Implement all applicable patterns from this list, in this order:

Priority	Pattern	What it communicates
1	Shared element (`name`)	"Same thing — going deeper"
2	Suspense reveal	"Data loaded"
3	List identity (per-item `key`)	"Same items, new arrangement"
4	State change (`enter`/`exit`)	"Something appeared/disappeared"
5	Route change (page-level)	"Going to a new place"

This is an implementation order, not a "pick one" list. Implement every pattern that fits the app. Only skip a pattern if the app has no use case for it.

Choosing Animation Style

Context	Animation	Why
Hierarchical navigation (list → detail)	Type-keyed `nav-forward` / `nav-back`	Communicates spatial depth
Lateral navigation (tab-to-tab)	Bare `<ViewTransition>` (fade) or `default="none"`	No depth to communicate
Suspense reveal	`enter`/`exit` string props	Content arriving
Revalidation / background refresh	`default="none"`	Silent — no animation needed

Reserve directional slides for hierarchical navigation (list → detail) and ordered sequences (prev/next photo, carousel, paginated results). For ordered sequences, the direction communicates position: "next" slides from right, "previous" from left. Lateral/unordered navigation (tab-to-tab) should not use directional slides — it falsely implies spatial depth.

Availability

Next.js: Do not install react@canary — the App Router already bundles React canary internally. ViewTransition works out of the box. npm ls react may show a stable-looking version; this is expected.
Without Next.js: Install react@canary react-dom@canary (ViewTransition is not in stable React).
Browser support: Chromium 125+ (React needs the v2 object form of startViewTransition), Firefox 144+, Safari 18.2+. Graceful degradation on unsupported browsers.

Implementation Workflow

When adding view transitions to an existing app, follow references/implementation.md step by step. Start with the audit — do not skip it. Use references/css-recipes.md for the applicable CSS and adapt it to the app.

Core Concepts

The `<ViewTransition>` Component

import { ViewTransition } from 'react';

<ViewTransition>
  <Component />
</ViewTransition>

React auto-assigns a unique view-transition-name and calls document.startViewTransition behind the scenes. Never call startViewTransition yourself.

Animation Triggers

Trigger	When it fires
enter	`<ViewTransition>` first inserted during a Transition
exit	`<ViewTransition>` first removed during a Transition
update	DOM mutations inside a `<ViewTransition>`, or the boundary itself changing size/position due to an immediate sibling. With nested VTs, mutation applies to the innermost one
share	Named VT unmounts and another with same `name` mounts in the same Transition

Only startTransition, useDeferredValue, or Suspense activate VTs. Regular setState does not animate.

Critical Placement Rule

<ViewTransition> only activates enter/exit if it appears before any DOM nodes:

// Works
<ViewTransition enter="auto" exit="auto">
  <div>Content</div>
</ViewTransition>

// Broken — div wraps the VT, suppressing enter/exit
<div>
  <ViewTransition enter="auto" exit="auto">
    <div>Content</div>
  </ViewTransition>
</div>

Styling with View Transition Classes

Props

Values: "auto" (browser cross-fade), "none" (disabled), "class-name" (custom CSS), or { [type]: value } for type-specific animations.

<ViewTransition default="none" enter="slide-in" exit="slide-out" share="morph" />

If default is "none", all triggers are off unless explicitly listed.

CSS Pseudo-Elements

::view-transition-old(.class) — outgoing snapshot
::view-transition-new(.class) — incoming snapshot
::view-transition-group(.class) — container
::view-transition-image-pair(.class) — old + new pair

See references/css-recipes.md for ready-to-use animation recipes.

Transition Types

Tag transitions with addTransitionType so VTs can pick different animations based on context. Call it multiple times to stack types — different VTs in the tree react to different types:

startTransition(() => {
  addTransitionType('nav-forward');
  addTransitionType('select-item');
  router.push('/detail/1');
});

Pass an object to map types to CSS classes. Works on enter, exit, and share:

<ViewTransition
  enter={{ 'nav-forward': 'slide-from-right', 'nav-back': 'slide-from-left', default: 'none' }}
  exit={{ 'nav-forward': 'slide-to-left', 'nav-back': 'slide-to-right', default: 'none' }}
  share={{ 'nav-forward': 'morph-forward', 'nav-back': 'morph-back', default: 'morph' }}
  default="none"
>
  <Page />
</ViewTransition>

enter and exit don't have to be symmetric. For example, fade in but slide out directionally:

<ViewTransition
  enter={{ 'nav-forward': 'fade-in', 'nav-back': 'fade-in', default: 'none' }}
  exit={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
  default="none"
>

TypeScript: ViewTransitionClassPerType requires a default key in the object.

For apps with multiple pages, extract the type-keyed VT into a reusable wrapper:

export function DirectionalTransition({ children }: { children: React.ReactNode }) {
  return (
    <ViewTransition
      enter={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
      exit={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
      default="none"
    >
      {children}
    </ViewTransition>
  );
}

`router.back()` and Browser Back Button

router.back() and the browser's back/forward buttons carry no transition types, so type-keyed animations (directional slides) resolve to their default and don't play — untyped shared-element morphs still apply. For typed animations, use router.push() with an explicit URL.

Types and Suspense

Types are available during navigation but not during subsequent Suspense reveals (separate transitions, no type). Use type maps for page-level enter/exit; use simple string props for Suspense reveals.

Shared Element Readiness

A shared element transition can pair elements only when both the old and new views are rendered in the same Transition. If incoming content suspends, only its fallback exists for that update; the resolved content appears in a later Suspense transition and can be animated separately.

Shared Element Transitions

Same name on two VTs — one unmounting, one mounting — creates a shared element morph:

<ViewTransition name="hero-image">
  <img src="/thumb.jpg" onClick={() => startTransition(() => onSelect())} />
</ViewTransition>

// On the other view — same name
<ViewTransition name="hero-image">
  <img src="/full.jpg" />
</ViewTransition>

Only one VT with a given name can be mounted at a time — use unique names (photo-${id}). Watch for reusable components: if a component with a named VT is rendered in both a modal/popover and a page, both mount simultaneously and break the morph. Either make the name conditional (via a prop) or move the named VT out of the shared component into the specific consumer.
share takes precedence over enter/exit. Think through each navigation path: when no matching pair forms (e.g., the target page doesn't have the same name), enter/exit fires instead. Consider whether the element needs a fallback animation for those paths.
Two ways a wired-up morph silently never fires: (1) default="none" with no explicit share prop — share resolves to none; (2) type-keyed share where the navigation never adds the type — a plain link click resolves the map's default. Every link that should morph must add the type (transitionTypes on next/link, or addTransitionType).
Never use a fade-out exit on pages with shared morphs — use a directional slide instead.

Common Patterns

Enter/Exit

{show && (
  <ViewTransition enter="fade-in" exit="fade-out"><Panel /></ViewTransition>
)}

List Reorder

{items.map(item => (
  <ViewTransition key={item.id}><ItemCard item={item} /></ViewTransition>
))}

Trigger inside startTransition. Avoid wrapper <div>s between list and VT.

Layout Displacement Morph

Only content inside an activated boundary animates position — everything else teleports to its new layout spot. Wrap the sibling content below a growing/shrinking list in a bare <ViewTransition> so it glides instead of jumping. See Layout Displacement Morph.

Composing Shared Elements with List Identity

Shared elements and list identity are independent concerns — don't confuse one for the other. When a list item contains a shared element (e.g., an image that morphs into a detail view), use two nested <ViewTransition> boundaries:

{items.map(item => (
  <ViewTransition key={item.id}>                                      {/* list identity */}
    <Link href={`/items/${item.id}`}>
      <ViewTransition name={`item-image-${item.id}`} share="morph">   {/* shared element */}
        <Image src={item.image} />
      </ViewTransition>
      <p>{item.name}</p>
    </Link>
  </ViewTransition>
))}

The outer VT handles list reorder/enter animations. The inner VT handles the cross-route shared element morph. Missing either layer means that animation silently doesn't happen.

Force Re-Enter with `key`

<ViewTransition key={searchParams.toString()} enter="slide-up" default="none">
  <ResultsGrid />
</ViewTransition>

Caution: If wrapping <Suspense>, changing key remounts the boundary and refetches.

Suspense Fallback to Content

Simple cross-fade:

<ViewTransition>
  <Suspense fallback={<Skeleton />}><Content /></Suspense>
</ViewTransition>

Directional reveal:

<Suspense fallback={<ViewTransition exit="slide-down"><Skeleton /></ViewTransition>}>
  <ViewTransition enter="slide-up" default="none"><Content /></ViewTransition>
</Suspense>

For more patterns, see references/patterns.md.

How Multiple VTs Interact

Every VT matching the trigger fires simultaneously in a single document.startViewTransition. VTs in different transitions (navigation vs later Suspense resolve) don't compete.

# React View Transitions

Animate between UI states using the browser's native `document.startViewTransition`. Declare *what* with `<ViewTransition>`, trigger *when* with `startTransition` / `useDeferredValue` / `Suspense`, control *how* with CSS classes. Unsupported browsers skip animations gracefully.

## When to Animate

Every `<ViewTransition>` should communicate a spatial relationship or continuity. If you can't articulate what it communicates, don't add it.

Implement **all** applicable patterns from this list, in this order:

| Priority | Pattern | What it communicates |
|----------|---------|---------------------|
| 1 | **Shared element** (`name`) | "Same thing — going deeper" |
| 2 | **Suspense reveal** | "Data loaded" |
| 3 | **List identity** (per-item `key`) | "Same items, new arrangement" |
| 4 | **State change** (`enter`/`exit`) | "Something appeared/disappeared" |
| 5 | **Route change** (page-level) | "Going to a new place" |

This is an implementation order, not a "pick one" list. Implement every pattern that fits the app. Only skip a pattern if the app has no use case for it.

### Choosing Animation Style

| Context | Animation | Why |
|---------|-----------|-----|
| Hierarchical navigation (list → detail) | Type-keyed `nav-forward` / `nav-back` | Communicates spatial depth |
| Lateral navigation (tab-to-tab) | Bare `<ViewTransition>` (fade) or `default="none"` | No depth to communicate |
| Suspense reveal | `enter`/`exit` string props | Content arriving |
| Revalidation / background refresh | `default="none"` | Silent — no animation needed |

Reserve directional slides for hierarchical navigation (list → detail) and ordered sequences (prev/next photo, carousel, paginated results). For ordered sequences, the direction communicates position: "next" slides from right, "previous" from left. Lateral/unordered navigation (tab-to-tab) should not use directional slides — it falsely implies spatial depth.

## Implementation Workflow

When adding view transitions to an existing app, **follow [references/implementation.md](references/implementation.md) step by step.** Start with the audit — do not skip it. Use [references/css-recipes.md](references/css-recipes.md) for the applicable CSS and adapt it to the app.

---

## Core Concepts

### The `<ViewTransition>` Component

```jsx
import { ViewTransition } from 'react';

<ViewTransition>
  <Component />
</ViewTransition>
```

React auto-assigns a unique `view-transition-name` and calls `document.startViewTransition` behind the scenes. Never call `startViewTransition` yourself.

### Animation Triggers

| Trigger | When it fires |
|---------|--------------|
| **enter** | `<ViewTransition>` first inserted during a Transition |
| **exit** | `<ViewTransition>` first removed during a Transition |
| **update** | DOM mutations inside a `<ViewTransition>`, or the boundary itself changing size/position due to an immediate sibling. With nested VTs, mutation applies to the innermost one |
| **share** | Named VT unmounts and another with same `name` mounts in the same Transition |

Only `startTransition`, `useDeferredValue`, or `Suspense` activate VTs. Regular `setState` does not animate.

### Critical Placement Rule

`<ViewTransition>` only activates enter/exit if it appears **before any DOM nodes**:

```jsx
// Works
<ViewTransition enter="auto" exit="auto">
  <div>Content</div>
</ViewTransition>

// Broken — div wraps the VT, suppressing enter/exit
<div>
  <ViewTransition enter="auto" exit="auto">
    <div>Content</div>
  </ViewTransition>
</div>
```

---

## Styling with View Transition Classes

### Props

Values: `"auto"` (browser cross-fade), `"none"` (disabled), `"class-name"` (custom CSS), or `{ [type]: value }` for type-specific animations.

```jsx
<ViewTransition default="none" enter="slide-in" exit="slide-out" share="morph" />
```

If `default` is `"none"`, all triggers are off unless explicitly listed.

### CSS Pseudo-Elements

- `::view-transition-old(.class)` — outgoing snapshot
- `::view-transition-new(.class)` — incoming snapshot
- `::view-transition-group(.class)` — container
- `::view-transition-image-pair(.class)` — old + new pair

See [references/css-recipes.md](references/css-recipes.md) for ready-to-use animation recipes.

---

## Transition Types

Tag transitions with `addTransitionType` so VTs can pick different animations based on context. Call it multiple times to stack types — different VTs in the tree react to different types:

```jsx
startTransition(() => {
  addTransitionType('nav-forward');
  addTransitionType('select-item');
  router.push('/detail/1');
});
```

Pass an object to map types to CSS classes. Works on `enter`, `exit`, **and** `share`:

```jsx
<ViewTransition
  enter={{ 'nav-forward': 'slide-from-right', 'nav-back': 'slide-from-left', default: 'none' }}
  exit={{ 'nav-forward': 'slide-to-left', 'nav-back': 'slide-to-right', default: 'none' }}
  share={{ 'nav-forward': 'morph-forward', 'nav-back': 'morph-back', default: 'morph' }}
  default="none"
>
  <Page />
</ViewTransition>
```

`enter` and `exit` don't have to be symmetric. For example, fade in but slide out directionally:

```jsx
<ViewTransition
  enter={{ 'nav-forward': 'fade-in', 'nav-back': 'fade-in', default: 'none' }}
  exit={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
  default="none"
>
```

**TypeScript:** `ViewTransitionClassPerType` requires a `default` key in the object.

For apps with multiple pages, extract the type-keyed VT into a reusable wrapper:

```jsx
export function DirectionalTransition({ children }: { children: React.ReactNode }) {
  return (
    <ViewTransition
      enter={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
      exit={{ 'nav-forward': 'nav-forward', 'nav-back': 'nav-back', default: 'none' }}
      default="none"
    >
      {children}
    </ViewTransition>
  );
}
```

### `router.back()` and Browser Back Button

`router.back()` and the browser's back/forward buttons carry **no transition types**, so type-keyed animations (directional slides) resolve to their `default` and don't play — untyped shared-element morphs still apply. For typed animations, use `router.push()` with an explicit URL.

### Types and Suspense

Types are available during navigation but **not** during subsequent Suspense reveals (separate transitions, no type). Use type maps for page-level enter/exit; use simple string props for Suspense reveals.

### Shared Element Readiness

A shared element transition can pair elements only when both the old and new views are rendered in the same Transition. If incoming content suspends, only its fallback exists for that update; the resolved content appears in a later Suspense transition and can be animated separately.

---

## Shared Element Transitions

Same `name` on two VTs — one unmounting, one mounting — creates a shared element morph:

```jsx
<ViewTransition name="hero-image">
  <img src="/thumb.jpg" onClick={() => startTransition(() => onSelect())} />
</ViewTransition>

// On the other view — same name
<ViewTransition name="hero-image">
  <img src="/full.jpg" />
</ViewTransition>
```

- Only one VT with a given `name` can be mounted at a time — use unique names (`photo-${id}`). Watch for reusable components: if a component with a named VT is rendered in both a modal/popover *and* a page, both mount simultaneously and break the morph. Either make the name conditional (via a prop) or move the named VT out of the shared component into the specific consumer.
- `share` takes precedence over `enter`/`exit`. Think through each navigation path: when no matching pair forms (e.g., the target page doesn't have the same name), `enter`/`exit` fires instead. Consider whether the element needs a fallback animation for those paths.
- Two ways a wired-up morph silently never fires: (1) `default="none"` with no explicit `share` prop — share resolves to none; (2) type-keyed `share` where the navigation never adds the type — a plain link click resolves the map's `default`. Every link that should morph must add the type (`transitionTypes` on `next/link`, or `addTransitionType`).
- Never use a fade-out exit on pages with shared morphs — use a directional slide instead.

---

## Common Patterns

### Enter/Exit

```jsx
{show && (
  <ViewTransition enter="fade-in" exit="fade-out"><Panel /></ViewTransition>
)}
```

### List Reorder

```jsx
{items.map(item => (
  <ViewTransition key={item.id}><ItemCard item={item} /></ViewTransition>
))}
```

Trigger inside `startTransition`. Avoid wrapper `<div>`s between list and VT.

### Layout Displacement Morph

Only content inside an activated boundary animates position — everything else teleports to its new layout spot. Wrap the sibling content below a growing/shrinking list in a bare `<ViewTransition>` so it glides instead of jumping. See [Layout Displacement Morph](references/patterns.md#layout-displacement-morph).

### Composing Shared Elements with List Identity

Shared elements and list identity are independent concerns — don't confuse one for the other. When a list item contains a shared element (e.g., an image that morphs into a detail view), use two nested `<ViewTransition>` boundaries:

```jsx
{items.map(item => (
  <ViewTransition key={item.id}>                                      {/* list identity */}
    <Link href={`/items/${item.id}`}>
      <ViewTransition name={`item-image-${item.id}`} share="morph">   {/* shared element */}
        <Image src={item.image} />
      </ViewTransition>
      <p>{item.name}</p>
    </Link>
  </ViewTransition>
))}
```

The outer VT handles list reorder/enter animations. The inner VT handles the cross-route shared element morph. Missing either layer means that animation silently doesn't happen.

### Force Re-Enter with `key`

```jsx
<ViewTransition key={searchParams.toString()} enter="slide-up" default="none">
  <ResultsGrid />
</ViewTransition>
```

**Caution:** If wrapping `<Suspense>`, changing `key` remounts the boundary and refetches.

### Suspense Fallback to Content

Simple cross-fade:
```jsx
<ViewTransition>
  <Suspense fallback={<Skeleton />}><Content /></Suspense>
</ViewTransition>
```

Directional reveal:
```jsx
<Suspense fallback={<ViewTransition exit="slide-down"><Skeleton /></ViewTransition>}>
  <ViewTransition enter="slide-up" default="none"><Content /></ViewTransition>
</Suspense>
```

For more patterns, see [references/patterns.md](references/patterns.md).

Skill purpose: Guide for implementing smooth, native-feeling animations using React's View Transition API (`<ViewTransition>` component, `addTransitionType`, and CSS view transition pseudo-elements). Use this skill whenever the user wants to add page transitions, animate route changes, create shared element animations, animate enter/exit of components, animate list reorder, implement directional (forward/back) navigation animations, or integrate view transitions in Next.js. Also use when the user mentions view transitions, `startViewTransition`, `ViewTransition`, transition types, or asks about animating between UI states in React without third-party animation libraries.
