npm-prune

Synopsis#

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 those present in the node_modules folder that are not listed as any package's dependency list.

If the --omit=dev flag is specified or the NODE_ENV environment variable is set to production, this command will remove the packages specified in your devDependencies.

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, extraneous modules are pruned automatically, so you'll only need this command with the --production flag. However, in the real world, operation is not always "normal". When crashes or mistakes happen, this command can help clean up any resulting garbage.
