Minor Changes

View Transitions 🚀

We're excited to release experimental support for the the View Transitions API in React Router! You can now trigger navigational DOM updates to be wrapped in document.startViewTransition to enable CSS animated transitions on SPA navigations in your application. (#10916)

The simplest approach to enabling a View Transition in your React Router app is via the new <Link unstable_viewTransition> prop. This will cause the navigation DOM update to be wrapped in document.startViewTransition which will enable transitions for the DOM update. Without any additional CSS styles, you'll get a basic cross-fade animation for your page.

If you need to apply more fine-grained styles for your animations, you can leverage the unstable_useViewTransitionState hook which will tell you when a transition is in progress and you can use that to apply classes or styles:

function ImageLink(to, src, alt) {
  const isTransitioning = unstable_useViewTransitionState(to);
  return (
    <Link to={to} unstable_viewTransition>
      <img
        src={src}
        alt={alt}
        style={{
          viewTransitionName: isTransitioning ? "image-expand" : "",
        }}
      />
    </Link>
  );
}

You can also use the <NavLink unstable_viewTransition> shorthand which will manage the hook usage for you and automatically add a transitioning class to the <a> during the transition:

a.transitioning img {
  view-transition-name: "image-expand";
}

<NavLink to={to} unstable_viewTransition>
  <img src={src} alt={alt} />
</NavLink>

For an example usage of View Transitions, check out our fork of the awesome Astro Records demo.
