React Contentful not building with VITE

[bondia]

I moved an old project that uses "react-contenful" to use Vite instead of Webpack.
On dev mode it runs OK but when building "react-contentful" it fails on the browser.

index.4dc67e6f.js:41 Uncaught ReferenceError: require is not defined

The problem is that it is using require in client side.

const { createClient } = require('contentful');

Might be that it needs an import instead?
Any idea what is the underlying issue here?

Thanks a lot!
