An example repository demonstrating how to set up a pnpm monorepo.
first is the public package that is external-facing.
second is the internal package that is not published, but has types and functions used by first.
The repository shows how to build the package in a way that allows exporting types and source of first without
having the reference on second which will not be published.
Note that after building, first/dist/lib.js does not contain a reference to foo as it is not important.
This demonstrates how this setup allows importing types from second without bloating the bundle size of first.
