Utilizing Google Closure Library with Angular 6

I am looking to integrate the google closure library into my angular 6 application. To achieve this, I have utilized the following commands:

npm install google-closure-compiler
and 
npm install google-closure-library
.

My application can be successfully compiled and run. However, upon attempting to execute the tests using ng test, I encountered error messages: 

ERROR in ./node_modules/google-closure-library/closure/goog/bootstrap/nodejs.js
Module not found: Error: Can't resolve 'fs' in './node_modules/google-closure-library/closure/goog/bootstrap'

ERROR in ./node_modules/google-closure-library/closure/goog/promise/testsuiteadapter.js
Module not found: Error: Can't resolve 'promises_aplus_tests' in './node_modules/google-closure-library/closure/goog/promise/testsuiteadapter.js'

I followed the angular official demo example and simply added the tests along with installing these two libraries. It seems like I may need to configure the karma.conf.js, but I'm unsure how to proceed. Can anyone provide guidance on resolving this issue?

If you're experiencing issues, consider including the following in your webpack setup

node: {
  fs: 'empty'
}

For a practical example, check out how it's done in this repository
