Tag a published version.
[DEPRECATED] npm tag <name>@<version> [<tag>] See `dist-tag`
THIS COMMAND IS DEPRECATED. See npm-dist-tag for details.
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.
Tags can be used to provide an alias instead of version numbers. For example, npm currently uses the tag "next" to identify the upcoming version, and the tag "latest" to identify the current version.
A project might choose to have multiple streams of development, e.g., "stable", "canary".
Tags must share a namespace with version numbers, because they are specified in the same slot: npm install <pkg>@<version> vs npm install <pkg>@<tag>.
Tags that can be interpreted as valid semver ranges will be rejected. For example, v1.4 cannot be used as a tag, because it is interpreted by semver as >=1.4.0 <1.5.0. See https://github.com/npm/npm/issues/6082.
The simplest way to avoid semver problems with tags is to use tags that do not begin with a number or the letter v.
