Update View Transitions Docs

📋 General description or bullet points (if proposing new content)

Add "Removing <ViewTransitions/> Component section

• "What needs to change?"
• "What can I keep?"
• "How do I reuse my custom animations?"

Maybe add tracking of browser support, I personally will volunteer for keeping this updated

As of right now:

• Chrome and Edge support level 2
• Safari added level 1, I haven't found a good issue to track level 2
• Firefox has plans for level 1 in new couple months, Bugzilla

Great call out to document removing the component!

As for updating statuses... is there a predictable static link for checking each browser's status? I would prefer if we didn't have to ourselves literally say "Browser X, level Y support" but could have one link that never needs updating that is e.g.[current adoption status of Browser X](link we don't have to update)

Or, if some other source we trust is updating statuses, I would be OK to link to even a non-official source that we find reliable and have faith will themselves be updating.

How about the View Transitions API Docs In MDN?

[sarah11918]

That link looks amazing, exactly what I was thinking of! :raised_hands:

[OliverSpeir]

That link covers level 1 Astro needs level 2 to be able to replace the ViewTransitions component

Granted, mdn is currently a bit in transition between level 1 and 2 for the documentation, but liruifengv's link is fine. The startViewTransition table shows level 1 support and the @viewTransition table shows level 2 support.

@martrapp posted his page recently https://events-3bg.pages.dev/jotter/api/references/#w3c-drafts ... would this work? (lol, Martin just commented)

[OliverSpeir]

Also worth noting that we need to explain that transition persist won’t be supported by the browsers

[sarah11918]

Great addition! Looking for someone to run with this and make an initial draft PR for docs!

Just checking to see whether anyone is interested in picking this one up! We've got the link mentioned above for browser support, and a section on removing the component would be welcome!
