How to use modules from parent package in child?

Question

JavaScript

There is a package in the structure of which part of the functionality is placed in separate packages. How to organize so that child packages do not download all dependencies into node_modules, but only those that are not in the dependencies of the parent? The rest, respectively, were taken from the parent node_modules.
What other ways are there to not fill all the free space with duplicate modules?

   |- child-package-2
      |- ...
      |- package.json
