Tag a published version
npm tag <name>@<version> [<tag>]
Tags the specified version of the package with the specified tag, or the --tag config if not specified.
A tag can be used when installing packages as a reference to a version instead of using a specific version number:
npm install <name>@<tag>
When installing dependencies, a preferred tagged version may be specified:
npm install --tag <tag>
This also applies to npm dedupe.
Publishing a package always sets the "latest" tag to the published version.
npm help publish
npm help install
npm help dedupe
npm help registry
npm help config
npm help config
npm help npmrc
