Error importing svelte.ts files with a library

[nevil2]

I have a private Svelte library (topo-editor) which uses .svelte.ts files.

When I install this library in another SvelteKit application, I get errors such as:

Unexpected token (1:12) [plugin vite-plugin-svelte-module:optimize-svelte]

    node_modules/topo-editor/src/lib/edit/TextModal.svelte:17:7:
      17 │ } from './textManager.svelte.js';
         ╵        ~~~~~~~~~~~~~~~~~~~~~~~~~

It is the same whether the import is .svelte, .svelte.ts or .svelte.js.

Can you tell me how to fix.

Needed to add to vite.config.js

optimizeDeps: {
	exclude: ['svelte-library']
}
