Vanilla JS template fails

Vite 8 official StackBlitz Vanilla template fails with Cannot find native binding

Describe the bug

A freshly created official StackBlitz Vanilla JS project fails to start without any modifications.

The project installs dependencies successfully, but npm run dev fails before the dev server starts with:

Error: Cannot find native binding.

Downgrading to Vite 7 immediately fixes the issue.

Reproduction

1. Create a new Vanilla JS project from the official StackBlitz template.
2. Do not modify any files.
3. Run:

npm install
npm run dev

Expected behavior

The Vite development server starts successfully.

Actual behavior

The dev server fails during Rolldown initialization.

Terminal output:

> vite-starter@0.0.0 dev
> vite

[rolldown] Downloading @rolldown/binding-wasm32-wasi@1.1.5 on WebContainer...

(node:12) ExperimentalWarning: WASI is an experimental feature and might change at any time

Error: Cannot find native binding. npm has a bug related to optional dependencies (https://github.com/npm/cli/issues/4828). Please try `npm i` again after removing both package-lock.json and node_modules directory.

Environment

• Platform: StackBlitz WebContainers
• Browser: Chrome (latest)
• OS: Ubuntu
• Project: Official StackBlitz Vanilla JS starter
• No project modifications

Versions:

vite-starter@0.0.0
└── vite@8.1.5
    └── rolldown@1.1.5

Workaround

Downgrading to Vite 7 resolves the problem:

npm install -D vite@7
npm run dev

After downgrading, the same project starts normally.

Additional notes

This appears to be specific to the Vite 8/Rolldown startup path in the StackBlitz WebContainer environment, since the identical project works after downgrading to Vite 7.
