@semantic-release/github-npm-registry

semantic-release plugin to publish an npm package to GitHub’s npm registry.

Step	Description
verifyConditions	Verify the presence of the GITHUB_TOKEN environment variable, create or update the .npmrc file with GitHub’s npm registry URL, the token and verify the token is valid.
prepare	Update the package.json version and create the npm package tarball.
publish	Publish the npm package to GitHub’s npm registry.

Install

$ npm install @semantic-release/github-npm-registry -D

Usage

The plugin can be configured in the semantic-release configuration file:

{
  "plugins": ["@semantic-release/commit-analyzer", "@semantic-release/release-notes-generator", "@semantic-release/npm"]
}

Configuration

Npm registry authentication

The npm authentication configuration is required and can be set via environment variables.

Both the token and the legacy (username, password and email) authentication are supported. It is recommended to use the token authentication. The legacy authentication is supported as the alternative npm registries Artifactory and npm-registry-couchapp only supports that form of authentication.

Note: Only the auth-only level of npm two-factor authentication is supported, semantic-release will not work with the default auth-and-writes level.

Environment variables

Variable	Description
NPM_TOKEN	Npm token created via npm token create
NPM_USERNAME	Npm username created via npm adduser or on npmjs.com
NPM_PASSWORD	Password of the npm user.
NPM_EMAIL	Email address associated with the npm user

Use either NPM_TOKEN for token authentication or NPM_USERNAME, NPM_PASSWORD and NPM_EMAIL for legacy authentication

Options

Options	Description	Default
npmPublish	Whether to publish the npm package to the registry. If false the package.json version will still be updated.	false if the package.json private property is true, true otherwise.
pkgRoot	Directory path to publish.	.
tarballDir	Directory path in which to write the the package tarball. If false the tarball is not be kept on the file system.	false

Note: The pkgRoot directory must contain a package.json. The version will be updated only in the package.json and npm-shrinkwrap.json within the pkgRoot directory.

Note: If you use a shareable configuration that defines one of these options you can set it to false in your semantic-release configuration in order to use the default value.

Npm configuration

The plugin uses the npm CLI which will read the configuration from .npmrc. See npm config for the option list.

The dist-tag can be configured in the package.json and will take precedence over the configuration in .npmrc:

{
  "publishConfig": {
    "tag": "latest"
  }
}

The registry setting will be ignored. It is hardcoded to https://npm.pkg.github.com.

Examples

The npmPublish and tarballDir option can be used to skip the publishing to the npm registry and instead, release the package tarball with another plugin. For example with the @semantic-release/github plugin:

{
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    [
      "@semantic-release/npm",
      {
        "npmPublish": false,
        "tarballDir": "dist"
      }
    ],
    [
      "@semantic-release/github",
      {
        "assets": "dist/*.tgz"
      }
    ]
  ]
}

When publishing from a sub-directory with the pkgRoot option, the package.json and npm-shrinkwrap.json updated with the new version can be moved to another directory with a postpublish npm script. For example with the @semantic-release/git plugin:

{
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    [
      "@semantic-release/npm",
      {
        "pkgRoot": "dist"
      }
    ],
    [
      "@semantic-release/git",
      {
        "assets": ["package.json", "npm-shrinkwrap.json"]
      }
    ]
  ]
}

{
  "scripts": {
    "postpublish": "cp -r dist/package.json . && cp -r dist/npm-shrinkwrap.json ."
  }
}
