Deprecating npm Packages

Once your packages have been pushed to an npm hosted repository, you can mark them as deprecated. This is useful when a newer version of the package is available and you want to warn people that the old package has reached end of life, or you want to avoid usage and warn your users for some other reason.

The npm deprecate command uses a registry configuration value to inform where the package lives. To deprecate an existing package, use a command like the following:

npm deprecate --registry http://localhost:8081/repository/npm-internal/ testproject1@0.0.1 "This package is deprecated" 

If you change your mind, you can reverse this action using the same command. To un-deprecate a package, pass an empty string to the deprecate command:

npm deprecate --registry http://localhost:8081/repository/npm-internal/ testproject1@0.0.1 ""

The message text is persisted in the deprecated attribute of the packageJson section for the asset and can be viewed in the user interface.
