How to count the number of installed packages, including dependencies

Question

Is there an easy way to obtain a count of installed npm packages, both global and local to an application?

For example, after running create-react-app [1], I get screens-full of packages and dependencies installed when I enter the npm ls command.

How to find a count ("cardinality") of said packages and dependencies eludes me. Tyvm, Keith :^)
