NAME

       npm-prune - Remove extraneous packages

   Synopsis
         npm prune [[<@scope>/]<pkg>...] [--production] [--dry-run] [--json]

   Description
       This  command  removes  "extraneous"  packages.   If a package name is provided, then only
       packages matching one of the supplied names are removed.

       Extraneous packages are packages that are not listed on the parent package's  dependencies
       list.

       If  the  --production  flag  is  specified  or the NODE_ENV environment variable is set to
       production, this command will remove  the  packages  specified  in  your  devDependencies.
       Setting --no-production will negate NODE_ENV being set to production.

       If the --dry-run flag is used then no changes will actually be made.

       If  the  --json  flag  is  used  then  the changes npm prune made (or would have made with
       --dry-run) are printed as a JSON object.

       In  normal  operation  with  package-locks  enabled,   extraneous   modules   are   pruned
       automatically  when  modules  are  installed  and  you'll  only need this command with the
       --production flag.

       If you've disabled package-locks then extraneous modules will not be removed and  it's  up
       to you to run npm prune from time-to-time to remove them.
