How to generate correct prop types when the prop-types package is not explicitly imported?

Is there a recommended way to generate prop types when the prop-types package is not explicitly imported into each component? For example, in my project, PropTypes is provided as a global through webpack's providePlugin:

config: {
    plugins: [
        new ProvidePlugin({
               PropTypes: 'prop-types',
        }),
    ]
};

So PropTypes is available to any react component—even when it is not imported.

I see the resolveToModule util looks for the prop-types import, and if it is not found, we end up with custom prop types rather than their actual type, like string or bool. It seems I can create a handler to generate prop types even when the prop-types package is not explicitly imported, but is there an already existing handler or other way to do this that addresses this case?

まず resolveToModule util と prop-types の既存の handler を読みます。webpack ProvidePlugin が明示的な prop-types の import なしで PropTypes を提供するケースを再現し、その後、既存の handler がそれをサポートしているか判断します。生成された出力が custom ではなく string や bool などの具体的な型を報告すれば完了です。
