-When bundling to CommonJS, i.e `output.format === 'cjs'`, make sure that you do not set `output.exports` to `'named'`. The default value of `'auto'` will usually work, but you can also set it explicitly to `'default'`. That makes sure that Rollup assigns the default export that was generated for your CommonJS entry point to `module.exports`, and semantics do not change.
