    Cannot find module 'vfile/do-not-use-conditional-minpath' from 'dist/index.mjs'

don't know why, can't search for this.

My usage is simple

import { unified } from 'unified';
import remarkParse from 'remark-parse';
import { VFile } from 'vfile';
import retidStringify, { IOptions } from './retid-stringify';
import { Root as MdastRoot, Content as MdastContent } from 'mdast';

export const md2tidProcessor = unified().use(remarkParse).use(retidStringify);

export async function md2tid(markdownString: string): Promise<string> {
  const vFile = new VFile({ path: 'fileName', value: markdownString });
  const file = await md2tidProcessor.process(vFile);
  return file.value as string;
}

export function toString(value: MdastRoot | MdastContent | string, options: IOptions) {
  if (typeof value === 'string') {
    value = { type: 'paragraph', children: [{ type: 'text', value }] };
  }

  if (value.type !== 'root') {
    value = { type: 'root', children: [value] };
  }

  return unified().use(retidStringify, options).stringify(value);
}

Found it on bundled file, but don't know why

import { decodeString as decodeString$1 } from 'micromark-util-decode-string';
import { toString as toString$2 } from 'mdast-util-to-string';
import { ok } from 'devlop';
import { path } from 'vfile/do-not-use-conditional-minpath';
import { proc } from 'vfile/do-not-use-conditional-minproc';
import { isUrl, urlToPath } from 'vfile/do-not-use-conditional-minurl';

Sounds like you need to fix your bundler. This should work

Adding on the stack trace includes jest.

[email protected]/node_modules/jest-resolve/build/resolver.js:324:11

Jest is known to have problems with ES modules (ESM). They have experimental ESM support https://jestjs.io/docs/ecmascript-modules but it has been experimental for years and has known bugs.

Consider dropping Jest entirely if you can, there are alternatives like node:test and vitest which do fully support ESM.
Or you could wrap jest with another tool like vite https://hung.dev/posts/jest-vite

Okay, I did spend some time make rollup + jest work with esm. I will switch to vite to see if it works.

If you are stuck using jest, you will need to add entries to the moduleNameMapper in jest config to point jest to the absolute path for these files:

moduleNameMapper: {
    ...,
    "vfile/do-not-use-conditional-minpath": "<rootDir>/node_modules/vfile/lib/minpath.browser.js",
    "vfile/do-not-use-conditional-minproc": "<rootDir>/node_modules/vfile/lib/minproc.browser.js",
    "vfile/do-not-use-conditional-minurl": "<rootDir>/node_modules/vfile/lib/minurl.browser.js",
  },
