View Transitions

Learn how to use the View Transitions API with React Router for smooth page transitions.

​
Overview

The View Transitions API allows you to create smooth, animated transitions between different states of your application. React Router integrates with this API to provide seamless page transitions.

​
Browser Support

The View Transitions API is supported in:
  • Chrome/Edge 111+
  • Safari 18+
  • Firefox (experimental)
React Router gracefully degrades in browsers without support.

​
Enabling View Transitions

Enable view transitions on navigation: 
import { Link } from "react-router";

export default function Navigation() {
  return (
    <nav>
      <Link to="/" viewTransition>
        Home
      </Link>
      <Link to="/about" viewTransition>
        About
      </Link>
      <Link to="/products" viewTransition>
        Products
      </Link>
    </nav>
  );
}

​
Programmatic Navigation

Use view transitions with navigate: 
import { useNavigate } from "react-router";

export default function ProductCard({ product }) {
  const navigate = useNavigate();

  function handleClick() {
    navigate(`/products/${product.id}`, {
      viewTransition: true,
    });
  }

  return (
    <div onClick={handleClick}>
      <img src={product.image} alt={product.name} />
      <h3>{product.name}</h3>
    </div>
  );
}

​
Form Submissions

Animate form submission transitions: 
import { Form } from "react-router";

export default function ContactForm() {
  return (
    <Form method="post" viewTransition>
      <input type="email" name="email" />
      <textarea name="message" />
      <button type="submit">Send</button>
    </Form>
  );
}

​
Custom Animations

Define custom transition animations with CSS: 
/* Default fade transition */
::view-transition-old(root),
::view-transition-new(root) {
  animation-duration: 0.3s;
}

/* Slide transition */
@keyframes slide-from-right {
  from {
    transform: translateX(100%);
  }
}

@keyframes slide-to-left {
  to {
    transform: translateX(-100%);
  }
}

::view-transition-old(root) {
  animation: 0.3s ease-out both slide-to-left;
}

::view-transition-new(root) {
  animation: 0.3s ease-out both slide-from-right;
}

​
Named Transitions

Animate specific elements independently: 
// Product list page
export default function Products({ loaderData }: Route.ComponentProps) {
  return (
    <div>
      {loaderData.products.map((product) => (
        <article
          key={product.id}
          style={{ viewTransitionName: `product-${product.id}` }}
        >
          <img src={product.image} alt={product.name} />
          <h3>{product.name}</h3>
          <Link to={`/products/${product.id}`} viewTransition>
            View Details
          </Link>
        </article>
      ))}
    </div>
  );
}

// Product detail page
export default function ProductDetail({ loaderData }: Route.ComponentProps) {
  return (
    <div>
      <article
        style={{ viewTransitionName: `product-${loaderData.product.id}` }}
      >
        <img src={loaderData.product.image} alt={loaderData.product.name} />
        <h1>{loaderData.product.name}</h1>
        <p>{loaderData.product.description}</p>
      </article>
    </div>
  );
}
Style named transitions: 
::view-transition-old(product-*),
::view-transition-new(product-*) {
  /* Animate position and size */
  animation-duration: 0.4s;
  animation-timing-function: ease-in-out;
}

​
Conditional Transitions

Apply transitions based on conditions: 
import { useNavigate, useLocation } from "react-router";

export default function Gallery({ loaderData }: Route.ComponentProps) {
  const navigate = useNavigate();
  const location = useLocation();

  function openImage(imageId: string) {
    // Only use view transition when navigating forward
    const useTransition = !location.state?.fromDetail;

    navigate(`/gallery/${imageId}`, {
      viewTransition: useTransition,
      state: { fromGallery: true },
    });
  }

  return (
    <div className="gallery">
      {loaderData.images.map((image) => (
        <img
          key={image.id}
          src={image.thumbnail}
          onClick={() => openImage(image.id)}
          style={{ viewTransitionName: `image-${image.id}` }}
        />
      ))}
    </div>
  );
}
Prevent transitions for skip links: 
export default function Layout() {
  return (
    <div>
      <a href="#main" onClick={(e) => e.stopPropagation()}>
        Skip to content
      </a>
      <nav>
        <Link to="/" viewTransition>Home</Link>
        <Link to="/about" viewTransition>About</Link>
      </nav>
      <main id="main">
        <Outlet />
      </main>
    </div>
  );
}

​
Animation Direction

Change animation based on navigation direction: 
import { useNavigate, useLocation } from "react-router";
import { useEffect } from "react";

export default function Pages() {
  const location = useLocation();

  useEffect(() => {
    // Add data attribute for CSS to use
    const direction = location.state?.direction || "forward";
    document.documentElement.dataset.direction = direction;
  }, [location]);

  return <Outlet />;
}

function useDirectionalNavigate() {
  const navigate = useNavigate();

  return (to: string, direction: "forward" | "back" = "forward") => {
    navigate(to, {
      viewTransition: true,
      state: { direction },
    });
  };
}
CSS for directional animations: 
/* Forward navigation */
[data-direction="forward"] ::view-transition-old(root) {
  animation: slide-to-left 0.3s ease-out;
}

[data-direction="forward"] ::view-transition-new(root) {
  animation: slide-from-right 0.3s ease-out;
}

/* Back navigation */
[data-direction="back"] ::view-transition-old(root) {
  animation: slide-to-right 0.3s ease-out;
}

[data-direction="back"] ::view-transition-new(root) {
  animation: slide-from-left 0.3s ease-out;
}

​
Loading States

Animate loading states during transitions: 
import { useNavigation } from "react-router";
import { useEffect } from "react";

export default function Root() {
  const navigation = useNavigation();

  useEffect(() => {
    document.documentElement.dataset.loading = 
      navigation.state === "loading" ? "true" : "false";
  }, [navigation.state]);

  return <Outlet />;
}

[data-loading="true"] ::view-transition-new(root) {
  /* Add a loading indicator during transition */
  position: relative;
}

[data-loading="true"] ::view-transition-new(root)::after {
  content: "";
  position: absolute;
  top: 50%;
  left: 50%;
  width: 40px;
  height: 40px;
  margin: -20px 0 0 -20px;
  border: 3px solid #ccc;
  border-top-color: #000;
  border-radius: 50%;
  animation: spin 0.6s linear infinite;
}

@keyframes spin {
  to {
    transform: rotate(360deg);
  }
}

​
Reduced Motion

Respect user’s motion preferences: 
@media (prefers-reduced-motion: reduce) {
  ::view-transition-old(root),
  ::view-transition-new(root) {
    animation: none !important;
  }
}

​
JavaScript Control

Access the transition object for advanced control: 
import { useViewTransitionState } from "react-router";

export default function Component() {
  const isTransitioning = useViewTransitionState("/about");

  return (
    <div>
      {isTransitioning && <p>Transitioning to About...</p>}
    </div>
  );
}

​
Best Practices

  1. Keep animations short - 200-400ms for most transitions
  2. Use meaningful animations - Match the user’s mental model
  3. Respect reduced motion - Honor prefers-reduced-motion
  4. Test performance - Ensure smooth 60fps animations
  5. Provide fallbacks - Work in browsers without View Transitions support
  6. Use named transitions sparingly - Only for key elements
  7. Consider mobile - Simpler animations work better on slower devices
  8. Test across browsers - Support varies across browsers
