Description

After upgrading my Sveltekit project to use Vite 8, my build breaks due to Lucide. The new backbone of Vite 8 (rolldown) cannot resolve some modules, see below:

bash

error during build:
Build failed with 19 errors:

I don't use those mentioned icons in my poroject.

After investigating a bit it seems that those icons like file-audio has been renamed, here into file-headphone. And that "deprecated" icon stubs in dist/icons/ reference .svelte which don't exist anymore and hence cannot be resolved by rolldown.

This only happens on Windows for me.

I assume something needs to be updated in generateAliasesFiles.ts maybe like so?

typescript

// before
const output = `export { default } from "./${iconName}${
  separateAliasesFileExtension ? iconFileExtension : ''
}";\n`;

// after
const output = `export { default } from "./${iconName}${aliasImportFileExtension}";\n`;

Steps to reproduce

Upgrade Sveltekit project to vite 8 and @sveltejs/vite-plugin-svelte to 7
Build the app on Windows (via GH workflow)
See build failing
