What problem does this feature solve?

Related issue: #494

What does the proposed API look like?

If we can add a CI to detect duplicate dependencies, it will help us to unify the version of 3rd party dependencies and reduce duplicate dependencies.

@tunahan-guler This issue is about the duplicate package problem in this modern.js repository.

Can you describe the problem you are currently facing?

[tunahan-guler]

@chenjiahan I use my own library in my main project and subproject. I didn't add these as shared. I wonder if this will cause a problem.

I understand that your topic may not be in line with our current discussion. To manage shared dependencies, you should take care of this aspect yourself. You can explore options such as the pnpm workspace or any other suitable alternative.
