Describe the bug

Some libraries don't work with Svelte 5 out of the box. It will probably be impossible to make every library compatible given that some use stuffsvelte/internal (which they really shouldn't) and everything in there changed, but those who don't should be closely investigated. Feel free to post libraries you found that don't work in here, ideally along with a small reproduction (repro or "install and use component X").

Won't / can't fix

• @tanstack/svelte-table, because it usessvelte/internal in a way that can't be backportedSvelte 5 support: ERROR: No matching export in "a" for import "b" TanStack/table#5213 - but a new version of the library is underway with Svelte 5 support! In the meantime there's also a drop-in replacement available athttps://www.npmjs.com/package/tanstack-table-8-svelte-5
• cmdk-sv / shadcn-svelte search box - manually interacts with the DOM, needs change in the libraryFiltering breaks on Svelte-5 huntabyte/cmdk-sv#92
• Vercel AI SDK Svelte wrapper - a dependency of that library is usingbeforeUpdate, the dependency likely needs to be switched out for something elseSvelte 5 Support vercel/ai#3107

Fixed

• svelte-confetti
• svelte-range-slider-pips (throughfix: better interop of$state with actions/$: statements #10543)
