Add a --skip-dev-dependencies flag

[JohnBerd]

Feature request description

There are too many false positives in devDependencies React Native project, and I would like to add this tool to my CI without having to change the .depcheckrc each time I add a dev dependency.

It would be great to have an option to skip the devDependencies

Cheers!

So we actually used to have this option, then we deprecated it and finally removed it, there were too many issues with it... You can see here: #450

What false positives do you get?

Thank you for your quick answer!

Such a shame. Sorry for not having found this issue, so I have exactly the same problem.
For example with babel, types, typescript, eslint modules.
Anyway I don't want the devDependencies to be checked at all.

Dear code owners,
I am also looking for --skip-dev-dependencies flag implementation, but for another case:

I would like to use it to identify the incorrect situation, where some "dev dependency" is used in production code. Example of my expected usage: depcheck . --ignore-patterns test* --skip-dev-dependencies.

I am able to make code changes and provide the Pull Request for this new feature. But first, I would like to get "approval" from code owners that this feature makes sense for him.
