npm list only dev or prod depedencies

Question

I am trying to ls only the production dependencies from package.json following the docs

So I am doing

npm list -depth 0 -prod

or

npm list -depth 0 -only prod

But npm seems to ignore it and it lists both dependencies and devDependencies

Any idea how I can achieve that?

Answer 1

I found out that the command is not supported on 3.7.3 so I updated my npm version to 3.8.7 and the following command does the job

npm list -prod -depth 0

Answer 2

npm list -depth 0 -prod true Lists the dependencies and npm list -depth 0 -dev true lists the devDependencies. Those work for me. You are missing the true after the -prod or -dev flag.
