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** (layout-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 |
