npm-unpublish(1) -- Remove a package from the registry

SYNOPSIS

npm unpublish <name>[@<version>]

WARNING

It is generally considered bad behavior to remove versions of a library that others are depending on!

Consider using the deprecate command instead, if your intent is to encourage users to upgrade.

There is plenty of room on the registry.

DESCRIPTION

This removes a package version from the registry, deleting its entry and removing the tarball.

If no version is specified, or if all versions are removed then the root package entry is removed from the registry entirely.
