Publish to npm

With a package.json in the current directory, release-it will let npm bump the version in package.json (and package-lock.json if present), and publish to the npm registry.

  • If only the publish step should be skipped, use npm.publish: false.
  • If package.json should be ignored, its version should not be bumped, and nothing should be published to npm, use --no-npm or "npm": false in the release-it configuration.

Prerequisite checks

To prevent issues later in the process, release-it first checks whether the npm registry is up, the user is authenticated with npm and is a collaborator for the current package.

Some instances of npm registries, such as Nexus, do not support npm ping, npm whoami and/or npm access. If the error is a E400 or E404, release-it will give a warning but continue.

To skip these checks, use npm.skipChecks.

Skip publish

To bump the version in package.json with the release, but not publish to the registry:

{
  "npm": {
    "publish": false
  }
}

In case there is a package.json, but no npm-related tasks should be executed, use "npm": false (or --no-npm).

Ignore version

To ignore the version from package.json, (and use the latest Git tag instead):

{
  "npm": {
    "ignoreVersion": true
  }
}

Or --npm.ignoreVersion from the command line.

Tags

Use e.g. --npm.tag=beta to tag the package in the npm repository. With the --preRelease=beta shorthand, the npm dist-tag will have the same value (unless --npm.tag is used to override this). The default tag is "latest".

For a pre-release, the default tag is "next". The tag will be derived from the pre-release version (e.g. version 2.0.0-alpha.3 will result in tag "alpha"), unless overridden by setting npm.tag.

Public scoped packages

A scoped package (e.g. @user/package) is either public or private. By default, npm publish will publish a scoped package as private. Note that scoped packages require a paid account.

In order to publish a scoped package to the public registry, specify this at the root of package.json:

{
  "publishConfig": {
    "access": "public"
  }
}

The default value for private packages is "restricted".

Publish to private registry

The default registry is https://registry.npmjs.org. The publish to another registry, update or set the publishConfig in package.json. For example:

{
  "publishConfig": {
    "registry": "https://npm.pkg.github.com"
  }
}

Config public path of registry

The default public path is /package. To customize an alternative path, update or set the publishConfig. For example, if a third-party tool such as Verdaccio is used to build a private server to proxy npm registry, then the URL address of the web user interface is http://{{host}}-/web/detail/{{packageName}}:

{
  "publishConfig": {
    "publicPath": "/-/web/detail"
  }
}

Yarn

Using Yarn? It adds or overwrites global environment variable(s), causing authentication issues or not being able to publish. Set the publishConfig.registry value so release-it will use the --registry argument with this value for each npm command.

{
  "publishConfig": {
    "registry": "https://registry.npmjs.org"
  }
}

Two-factor authentication

In case two-factor authentication (2FA) is enabled for the package, release-it will ask for the one-time password (OTP).

The OTP can be provided from the command line (--npm.otp=123456). However, providing the OTP without a prompt basically defeats the purpose of 2FA (also, the OTP expires after a short period).

Publish path

Use npm.publishPath to publish only a specific folder. For example, set npm.publishPath to "dist". The default value is the current (root) folder (".").

Extra arguments

Use npm.versionArgs and/or npm.publishArgs to pass extra arguments to npm version and npm publish, respectively. Example:

{
  "npm": {
    "versionArgs": ["--allow-same-version", "--workspaces-update=false"],
    "publishArgs": ["--include-workspace-root"]
  }
}

Use npm.allowSameVersion to prevent throwing error when setting the new version to the same value as the current version. This option may become deprecated, it is recommended to use versionArgs for this.

Monorepos

Monorepos do not require extra configuration, but release-it handles only one package at a time. Also see how Git steps can be skipped. This is useful if, for instance, tagging the Git repo should be skipped.

To bump multiple package.json files in a monorepo to the same version, use the @release-it/bumper plugin.

Also see this monorepo recipe.

For Yarn workspaces, see the release-it-yarn-workspaces plugin.
