View Transitions API ​

Problem ​

Implement view transitions api in a production-friendly way with @vielzeug/routeit while keeping setup and cleanup explicit.

Runnable Example ​

The snippet below is copy-paste runnable in a TypeScript project with @vielzeug/routeit installed.

Enable browser-native page transitions:

ts
const router = createRouter({ viewTransition: true });

router.on('/', renderHome).on('/gallery', renderGallery).start();

// Override per-navigation
router.navigate('/gallery', { viewTransition: false });

Expected Output ​

  • The example runs without type errors in a standard TypeScript setup.
  • The main flow produces the behavior described in the recipe title.

Common Pitfalls ​

  • Forgetting cleanup/dispose calls can leak listeners or stale state.
  • Skipping explicit typing can hide integration issues until runtime.
  • Not handling error branches makes examples harder to adapt safely.
