React View Transitions Demo

Why it's ranked here

Worth ten minutes because the examples connect animation mechanics to common product behavior. The paired branches make the changes easier to isolate, while the working gallery shows how transitions interact with routing, asynchronous content, filtering, and immediate feedback.

What's good

The patterns cover more than decorative page changes. Shared photos preserve visual continuity, skeletons yield to loaded content, filtered items animate during reordering, and optimistic state keeps sort controls responsive. Reduced-motion rules disable every transition animation, while isolated header and search elements remain visually stable.

Tradeoffs

This is a private application, not a reusable component package. Its content comes from a fixed local photo collection, so it does not demonstrate remote data or persistence. The documented agent workflow is nondeterministic and may miss pages or patterns, requiring inspection and follow-up prompts.

How to use it well

Use it when prototyping motion in a React and Next.js interface or teaching an agent specific transition patterns. Compare the plain and animated branches, then port only the relevant techniques. It does not replace a production gallery backend, a component library, or deterministic automation.
