npm deprecate <pkg>[@<version>] <message>

This command will update the npm registry entry for a package, providing a deprecation warning to all who attempt to install it\.

It works on version ranges https://semver\.npmjs\.com/ as well as specific versions, so you can do something like this:

npm deprecate my-thing@"< 0\.2\.3" "critical bug fixed in v0\.2\.3"

Note that you must be the package owner to deprecate something\. See the owner and adduser help topics\.

To un-deprecate a package, specify an empty string ("") for the message argument\. Note that you must use double quotes with no space between them to format an empty string\.
