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.
