Esmodule version of the introduction of hast-util-from-dom leads to errors...

[rxliuli]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch rehype-mathjax@3.1.0 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/rehype-mathjax/lib/renderer.js b/node_modules/rehype-mathjax/lib/renderer.js

First, I am not a member of this project, but I am original author of this package.
I have been also faced this problem about a decade month ago.
I guess this is an issue of hast-util-from-dom, which package should be compiled as an esmodule.
The es6 and esmodule support is the ongoing task of this porject. Please read unifiedjs/rfcs#4 .

This is also definitely something your bundler can fix. And some of them do. So you might be able to solve it there.

I tried it in the create-react-app failed, I believe that most applications will fail.

webpack 4 has a lot of bugs. But you’re out of luck. CRA prevents you from working on that.

I don't know if WebPack has an error, but I know that if WebPack / Rollup can't be compatible, it will use it very unfriendly.

Webpack 5, Rollup, and Node support the way it is now. Your patch will break them.
For CRA, see: facebook/create-react-app#9994.

We (+ much more of the JS ecosystem) are moving to full ESM over the coming months: unifiedjs/unified#121

CRA migration WebPack 5 is a long-term process, so far, it has been completed 24%, then, the remark-math will be unavailable during this time before really complete. I am not opposing to support better ESModule standards, just want to remind, do compatibility processing. . .for example, now I can't use the CRA and ROLLUP package, so I can only use Patch-Node to modify until a certain time Remark-Math directly introduces no problem.

I use the remark-math project, use the Rollup package. https://github.com/rxliuli/joplin-search-intergration/blob/ff95928d5e/rollup.config.js

Why did you mention CRA before if you are now talking about (+ the links you share) Rollup?

do compatibility processing

This package is CJS. It uses a require to load a dual CJS/ESM package. Your bundler should use the CJS file. If it doesn’t, it’s either a bug there or it has to be configured in some way.

So how should rollup configure the hast-util-from-dom using a CommonJS version of rehype-mathjax?

Re this earlier message by @tani, what was your solution?

@rxliuli Can you answer this earlier question?
Otherwise, can you make a small reproduction: your project is giant, and I don’t have time to debug everything?

Because I also need to use MarkDown in the CRA project in the production environment, ITMDOWN-IT is currently used, but I want to unify them.

Forget it, I temporarily close this problem. Anyway, the question has been temporarily solved, and there is at least other options if not. . .
