ReferenceError: exports is not defined

[danez]

Since #702 react-codemirror throws an error for me. I haven't had time to dig deeper, but it seems that the commons file is loaded, but because of "type:module" it is interpreted as ESM.

This is how I import in my source:

import { useCallback } from 'react';
import { useTheme } from 'next-themes';
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
import { json } from '@codemirror/lang-json';
import { EditorView } from '@codemirror/view';

...

ref: reactjs/react-docgen#976

@danez I see that it is needed in many places, especially in Vite projects. So are you suggesting that I should remove it or keep it? Removing it might affect certain use cases, but keeping it could cause issues like the one you encountered. What do you think?

Technically the type: module is wrong because not all files in the packed package are esm.

Maybe it would be better to remove the type:module again and instead use *.cjs and *.mjs extension for commonjs/esm. Then nodejs will do the correct thing.
Not sure though if it solves the vite problem.

Could also leave the type:module and only change commonjs to generate *.cjs files. I will try that tomorrow.

Have the same error. 4.23.8 runs perfectly but with 4.23.9 I get the "exports is not defined" error.
