man npm-deprecate (1): Deprecate a version of a package

SYNOPSIS

npm deprecate <name>[@<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 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.
