To use this library with CRA

[pannchat]

I guess if you have to write mdx-js/loader with CRA, you can't use mdx-js/loader@next.
So, I used mdx-js/loader 1.6.22, to operate mdx-js/loader normally.

And in "react-scripts": "5.0.0",
Uncaught DOMException: Failed to extract 'create element' on 'Document': The tag name supplied error occurs.

So I solved it like this.

before:
package.json
"react-scripts": "5.0.0",

after:
package.json
"react-scripts": "4.0.3",

1. you can use @mdx-js/[email protected]
2. remove node_modules , package-lock.json
3. npm install
4. and try again

I'm sorry that the translation is not smooth.
