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 👜 !!!

🗃️ Do you love Lorenzo's Multi Sidebar for Starlight?

... then you'll appreciate that The Bag's Starlight support got you covered from day one: View transition support starting with the first npm release of @lorenzo_lewis/starlight-multi-sidebar!

Improved Support for swap()-related Topics!!

VtBotDebug now shows the changes that are made to the DOM during swap.

Support for swap() replacements is now automatically synced with Astro's main development. Astro extents the semantics of the swap() functions? All extensions are supported by The Bag and are available for your individual swaps!

More Starlight Improvements:

The selection of optional Starlight components keeps growing:

Ever wished clicking on Starlight's previous page and next page links would slide content from the left respectively from the right? Now you can enable <PageOrder /> on Starlight sites. This automatically alters the direction of the view transition. Visit a page further down the sidebar and get a forward navigation, visit a page further up, and you get a back navigation.

Eliminate the Pseudo-Scrolling of the Main Section: With <PageOffset />, The Bag offers a simple to use component that eliminates pseudo scrolling effects induced by morph transitions on elements that are larger than the viewport. Especially useful to get a smooth and neat transition animation for your main content.

Recently learned tricks

Improved Sidebar Handling: When you navigate to a page that has its entry within a collapsed category, the category is now automatically turned open. If the current page marker is outside the visible part of the sidebar, it is automatically scrolled into view. New: Support for your own customizations!

If you want to use transition:persist inside the main content area, you can do that now! As of v1.7.8 the <ReplacementSwap /> component handles data-astro-transition-persist attributes within the replaced DOM trees in the same way as Astro's built-in swap() function does.

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. |Component|Brotli bytes added| |-------|-----------------| Animation Style ✨| ~0.1k BrakePad 🦥 | ~0.2k Linter 🧹 | ~1.9k LoadingIndicator ⏳ | ~0.4k Move 🚟 | ~0.2k NoScroll 📜 | ~0.1k PageOffset 📄⇞ | ~0.1k Portal 🚪 | ~0.2k ReplacementSwap ↹ | ~0.5k Starlight … 🌟 | ~3.0k Swing 🎷 | ~0.1k VtBotDebug 🐛 | ~2.8k Zoom 🔎 | ~0.1k

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.
