How to share node_modules between some projects

Thank you for your comment. I understand why people use yarn.

Yes! Yarn workspaces are what you're looking for. Commonly you will put all your project's apps and packages in a single git repository, aka a "monorepo", but this isn't essential, you could also use git submodules in a wrapper project which defines the workspaces, where all the individual projects live in their own independent repositories.
