Vite CJS / ESModule warning

[jhwz]

When running a svelte-kit server with the project vite outputs the following warning:

@cfworker/uuid doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix.

It's no big problem, setting:

ssr: {
    noExternal: ['@cfworker/uuid']
}

in vite.config.js resolves the issue, but would be nice to have the warning removed.

This affects other modules as well

@cfworker/cosmos doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix.

Hi @jdanyow — I hit this issue with @cfworker/uuid while trying out Remix using Vite for Cloudflare Pages.

I'm not sure if the fix is as simple as it looks on the surface, but I'd love to see a fix that makes Vite happy.
