How to use npm package in Apache NIFI's Execute script processor ?

[#1]

I am building a job in which I have to validate phone numbers and we wants to use 'google-libphonenumber' npm package. I am using javascript in executescript processor. What is the correct way to include the npm package?

You might be able to use jvm-npm as a bridge to load that module, but see the documentation on the jvm-npm site for restrictions (such as needing to be a "pure" NPM module that does not depend on the Node.js API)
