### Synopsis

    npm dist-tag add <pkg>@<version> [<tag>]
    npm dist-tag rm <pkg> <tag>
    npm dist-tag ls [<pkg>]

    aliases: dist-tags

### Description

Add, remove, and enumerate distribution tags on a package:

- add: Tags the specified version of the package with the specified tag, or the `--tag` config if not specified. If you have two-factor authentication on auth-and-writes then you’ll need to include a one-time password on the command line with `--otp <one-time password>`, or at the OTP prompt.

- rm: Clear a tag that is no longer in use from the package. If you have two-factor authentication on auth-and-writes then you’ll need to include a one-time password on the command line with `--otp <one-time password>`, or at the OTP prompt.

- ls: Show all of the dist-tags for a package, defaulting to the package in the current prefix. This is the default action if none is 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 any other commands that resolve and install dependencies, such as `npm dedupe`, `npm update`, and `npm audit fix`.)

Publishing a package sets the `latest` tag to the published version unless the `--tag` option is used. For example, `npm publish --tag=beta`.

By default, `npm install <pkg>` (without any `@<version>` or `@<tag>` specifier) installs the `latest` tag.

### Purpose

Tags can be used to provide an alias instead of version numbers.

For example, a project might choose to have multiple streams of development and use a different tag for each stream, e.g., `stable`, `beta`, `dev`, `canary`.

By default, the `latest` tag is used by npm to identify the current version of a package, and `npm install <pkg>` (without any `@<version>` or `@<tag>` specifier) installs the `latest` tag. Typically, projects only use the `latest` tag for stable release versions, and use other tags for unstable versions such as prereleases.

The `next` tag is used by some projects to identify the upcoming version.

Other than `latest`, no tag has any special significance to npm itself.

### Caveats

This command used to be known as `npm tag`, which only created new tags, and so had a different syntax.

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`.
