Incorrect Type in package.json, Breaks Webpack 5

[thequailman]

Hello, this repo uses the wrong type specified in the package.json:

https://github.com/commonmark/commonmark.js/blob/master/package.json#L18

Webpack thinks it's commonjs, but it uses import/export syntax and breaks the loader. See this issue for a similar repo with the same problem and a workaround until it's fixed: webpack/webpack#11597

The intent was to preserve backwards-compatibility, so the package can still be used as commonjs.
If you've got a better way to do that, let us know. I don't know much about the JS ecosystem, and the person who did the PR for modules has been unresponsive.

As you can see from bin/commonmark, you can use ESM.

See #195 -- is this a dup or a distinct issue?

I think if you're using import/export syntax in /lib, you have to set the package.json "type": to "module". I fixed the issue by adding this rule:

			{
			  test: /\.js/,
			  include: /commonmark[\\/]lib[\\/]/,
			  type: "javascript/auto"
			},

This should be fixed by #203
