# npm-prune

Remove extraneous packages

## SYNOPSIS

    npm prune [[<@scope>/]<pkg>...] [--production]

## 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 `--production=false` will negate `NODE_ENV` being set to `production`.
