Won't unreferenced files be packaged? about rollup HOT 9 OPEN

There is actually en-US.d.ts, but there is no en-US.js file

from rollup.

I want to keep these files from being discarded by treeshake。
locale inludes:
| -- en.ts
| -- zh.ts
| -- index.ts

from rollup.

How can those files be needed when nothing imports them?

Thanks for the feedback！

For example, when I was developing a component library. I may only quote and use a certain language by default, but not all languages.

If the user wants to switch languages ​​during use, they can manually import it from '/module/locale/fr_FR'; then pass it to the component. So the component uses another language.

like https://ant.design/docs/react/i18n

import { ConfigProvider } from 'antd';
import frFR from 'antd/locale/fr_FR';

return (
  <ConfigProvider locale={frFR}>
    <App />
  </ConfigProvider>
);

from rollup.

But the current situation, for example, my locale includes multiple languages, but if I only reference one default language, then the other languages ​​will not be included in the built package, but they are actually needed. Is there any way to solve this problem?

If you want users to be able to manually import anything, you need to make all languages entry points. Otherwise even if they were bundled, they would just end up in some file and would be entirely unusable.

I understand what you mean, but if I quote it like this, I can't package it into /esm. Is there any better solution? Does treeshake support it? If supported, how to configure it?

from rollup.

Not sure I understand you. By entry point I mean adding all languages as entry points to the input option.

Sorry, maybe I don't understand what you mean. Would you mind helping me change the code so that files in _locale can also be packaged into the /esm/_locale/ directory? The en_US.js file is now missing
