The Bag of Tricks for Astro's View Transitions

The bag of tricks provides extensions & support around Astro's view transitions.

A current deployment of tech demos and the documentation can be found at https://events-3bg.pages.dev/

!!! NEW TRICKS ✨ IN THE BAG 👜 !!!

Brings you the latest version of @vtbag/element-crossing, with a bug fix for letting data-* properties cross over to the new page!

For details, see the CHANGELOG of the ElementCrossing.

Recently Learned Tricks

The Inspection Chamber DevTools now als work for pnpm projects!
Big shout out and "Thank You!" to Lukas for providing this fix!

New component for browser-native cross-document view transitions: The <CamShaft> component prevents the pseudo-smooth-scroll effect caused by view transition groups that exceed the height of the viewport when navigating to a different vertical scroll position.

The <TurnSignal> enables Astro's forward/backward animations provided by transition:animate to work with native cross-document @view-transition{}. Optionally you can configure the component with a total order of your site's pages, allowing it to automatically detect the transition direction.

The <ElementCrossing /> is a component for those of you who experiment with CSS-only cross-document view transitions and miss a way to preserve state of HTML elements across navigation: Transfer selected element state to the other side!

Inspection Chamber: See your view transitions like never before: examine every detail, reveal, debug, and optimize! Now, drill down into the effects of each pseudo-element introduced by the view transition API and even selectively toggle individual animations to better understand what’s happening! Summon the Inspection Chamber as a component (<InspectionChamber />) or install The Bag as an integration! and access the Chamber from the devToolbar!

Starlight Support: Ever wanted to see what your Starlight site looks like with view transitions enabled? Follow these steps to get rid of full page loads and make your Starlight site look like a SPA!

Reusable Components 🧩

• In need for extensions for view transitions because you have issues with iframes on your pages?
• Wanting support in understanding and debugging view transitions or simply want a second pair of eyes 👀 on your view transition settings?
• Looking for reusable animations or special transition effects?
• Want to use view transitions on your Starlight site?

The astro-vtbotpackage isn't a monolithic library. Use the components you need and only pay bandwidth for those.

Visit the documentation of the reusable components for detailed information.

• <Linter/>: A linter component that helps you identify problems when setting up transitions.

• <VtBotDebug/>: A Debugging component that logs the events and their data as they occur.

• <ReplacementSwap/>: An alterantive DOM swap(), which preserves elements in the original DOM to avoid reinitialization of iframes or CSS animations.

• <LoadIndicator>: Have you ever missed the visual feedback on sites with view transitions as to whether the app has noticed the click? You need a loading indicator! Here you go!

• Zoom, <Move> and Swing animations and the <AnimationsStyle/> component allows for extended styling options.

• <Portal/> component that forces all view transitions through a portal/loading page.

• <NoScroll/> keep the current vertical and horizontal scroll position when transitioning to the next page.

Tech Demos 🔥

The bag of tricks currently contains several technical demos that show examples of the implementation of various effects using the view transition events.

The sources are in this repository.

The Jotter 📓

Last but not least, the deployment also includes the ▶ Jotter ◀ with a wealth of information on transition events as well as background information and valuable tips & tricks on view transitions in Astro.

Some of the contents are technical demos, some are useful tools, and some are reusable components that you can use in your own project to handle edge cases that go beyond Astro's standard features.
