hi @walterbender I was working on this for a week I added tests for all functions. Please take a look or If you want to some changes I am happy to work on it

Hey, the tests look good but there are some issues
a-Im not sure why you changed the original synthutils file,
also please look at how the files are we exporting the files (there's an if condition, otherwise exporting modules like this throws reference errors)

And i think we are not supposed to change the package.json/lock files

[gitsofaryan]

Since your error is due to missing dependencies in package-lock.json, run:

npm install

@Shyam-Raghuwanshi It looks like this PR has been inactive for a while. Are you still working on it, or would you mind if I take over?

[walterbender]

The problem had been that somehow the dependencies were not getting set up properly. Once there were installed, it worked fine.

@walterbender i will fix

hi @walterbender please try again, I clone the branch separately and fix a dependencies issue and if you are still facing some issue please tell me
