[addon-info] PropTypes missing for build-storybook

[rwieruch]

In my development environment, addon-info works perfectly fine. It shows the PropTypes for each component:

However, once I build the Storybook for production with build-storybook -c .storybook -o dist and deploy it, the PropTypes are empty:

Anything I can do about it? That's one of my components:

...

const ContentButton = ({ onClick, children, className, ...props }) => (
    <BaseButton
      onClick={onClick}
      className={cs(className, 'content')}
      {...props}
    >
      {children}
    </BaseButton>
);

ContentButton.propTypes = {
  onClick: PropTypes.func.isRequired,
  children: PropTypes.string.isRequired,
  className: PropTypes.string,
};

ContentButton.displayName = 'ContentButton';

export default ContentButton;

Any help is really appreciated.

Do you potentially have a babel plugin or are you using a library that's stripping propTypes from a bundle in prod?

I wouldn't be aware of it.

.babelrc

{
  "presets": [
    "env",
    "react",
    "stage-2",
  ],
  "env": {
    "test": {
      "presets": [
        "env",
        "react",
        "stage-2",
      ],
      "plugins": ["require-context-hook"]
    }
  }
}

webpack.config.js in .storybook/

module.exports = (storybookBaseConfig, configType) => {
  storybookBaseConfig.module.rules.push(
    {
      test: /\.(js|jsx)$/,
      exclude: /node_modules/,
      use: ['babel-loader'],
    },
    {
      test: /\.(woff(2)?|ttf|eot)(\?v=\d+\.\d+\.\d+)?$/,
      use: ['file-loader'],
    },
    {
      test: /stories\.(js|jsx)?$/,
      loaders: [require.resolve('@storybook/addon-storysource/loader')],
      enforce: 'pre',
    },
  );

  return storybookBaseConfig;
};
