📝 Provide detailed reproduction steps (if any)

1. Open this stack blitz demo: https://stackblitz.com/edit/vitejs-vite-ovlnsp?file=src%2FMultiRootEditor.tsx
2. Try to import any translations/ file like in these docs (https://ckeditor5.github.io/docs/nightly/ckeditor5/latest/getting-started/setup/ui-language.html#npm)

✔️ Expected result

No errors. Translations should be properly typed.

❌ Actual result

Cannot find module `ckeditor5/translations/pl.js` or its corresponding type declarations.

When I downloaded this demo and ran it locally, I got the following error:

Cannot find module 'ckeditor5/translations/pl.js' or its corresponding type declarations.
  There are types at '/home/praca/Pobrane/vitejs-vite-75ppwy/node_modules/ckeditor5/dist/translations/pl.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.ts(2307)

This happens because "moduleResolution" in this project is set to "Node". According to the TypeScript documentation:

'node10' (previously called 'node') for Node.js versions older than v10, which only support CommonJS require. You probably won’t need to use node10 in modern code.

It looks like this issue is caused by the exports field in the package.json files in ckeditor5 and ckeditor5-premium-features, for which support was added in Node 12.

We could fix this by adding the following to exports in both packages:

"./dist/translations/*.js": {
  "types": "./dist/translations/*.d.ts",
  "import": "./dist/translations/*.js"
}

This would allow importing translations like so:

import coreTranslations from 'ckeditor5/dist/translations/pl.js';
//                                      ^^^^
import commercialTranslations from 'ckeditor5-premium-features/dist/translations/pl.js';
//                                                             ^^^^

However, since exports is supported as of Node 12 and this TypeScript configuration is discouraged, I think we can ignore this issue unless we get more feedback about it.

I have the same problem. How to solve it?
This doesn't work either
import translations from 'ckeditor5/dist/translations/ru.js';

[filipsobol]

This issue was resolved in 42.0.2. If you update to 42.0.2 or newer, you should be able to import translations like so:

import translations from 'ckeditor5/translations/ru.js';

I have the latest version
"ckeditor5": "43.0.0",

it helped me

// @ts-expect-error
import translations from 'ckeditor5/translations/ru.js';

If @ts-expect-error resolved this, then it's probably caused by using moduleResolution: 'node' in TypeScript, which should only be used with Node 10 and older. If you use TypeScript 5.0 or newer, you can change 'node' to 'bundler' to fix it. Otherwise, you can refer to the docs.
