How can I use absolute paths in my React styleguidist component library?

Question

I have a React component library that is used in a React app. The component library is setup using Styleguidist and webpack. I've setup webpack to use absolute paths using:

webpackConfig: {
  resolve: {
    modules: [path.resolve(__dirname, 'src/'), 'node_modules'],
  }
}

This works within the context of the component library. When I build the component library, the package looks like this:

/core
  /components
    /Table
    /Row

When I import the components into my app, I get an error:

Module not found: Can't resolve components/Row in /Users/myusername/Sites/mysite/node_modules/@mypackage/core/components/Table

I understand why the paths don't match in the context of node_modules, but I would've expected Webpack to transform those import paths during the build process. Is there something I'm missing? Or is this not possible?

While Styleguidist uses webpack, it turns out the build script we were using does not, so the webpack config is irrelevant. Instead, our build script (https://www.npmjs.com/package/cod-scripts) uses babel.

We ended up having to add a separate babel.config.js file to define absolute paths for babel using the babel-plugin-module-resolver package.

npm install babel-plugin-module-resolver --saveDev
npm install @babel/preset-react --saveDev

babel.config.js

module.exports = {
  plugins: [
    [
      'module-resolver',
      {
        root: ['./src'],
      },
    ],
  ],
  presets: ['@babel/preset-react'],
};
