SvelteKit Storybook TypeScript Package Import Issue

[Snuffkin1234]

Summary

Hello,
I'm working on a component library in SvelteKit using Svelte 5, TypeScript, and Storybook 8.4. My tsconfig is set to Nodenext, which has the side effect of requiring file extensions on imports. Sometimes Storybook works fine, and sometimes I get an error like this, [plugin:vite:import-analysis] Failed to resolve import "../enums/cssClasses/cardClasses.js" from "src/package/components/ClickableCard.svelte". Does the file exist?

The file is literally cardClasses.ts, but I need to import it as cardClasses.js, so the package will work after running svelte-package. How can I make this work with Storybook?

I could just point Storybook at the dist folder instead of src but that would remove a lot of the usefulness of Storybook for incremental debugging.

Thanks!
