Linking directory in ReactJS project

I found that users of Create-React-App script have issues with building few projects that are based on the same "core" library. Let's imagine that you have a ui directory where you keep all UI React components. And you have two projects - blog and shop.

Now you wish to use the shared UI components in both these projects. But if you will create a symlink to a "raw" source code (where you use ES2015) - you will see that your code can't be imported, because it expects that they should be already compiled.
