@semantic-release/npm

Set of semantic-release plugins for publishing to a npm registry.

verifyConditions

Verify the presence of the NPM_TOKEN environment variable, create or update the .npmrc file with the token and verify the token is valid.

getLastRelease

Determine the last release of the package on the npm registry.

publish

Update the package.json version, create the npm package tarball and publish to the npm registry.

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 at this point.

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. | true | | 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 contains a package.json. The version will be updated only in the package.json and npm-shrinkwrap.json within the pkgRoot directory.

Npm configuration

The plugins are based on npm and will use the configuration from .npmrc. See npm config for the option list.

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

{
  "publishConfig": {
    "registry": "https://registry.npmjs.org/",
    "tag": "latest"
  }
}

Usage

The plugins are used by default by semantic-release so no specific configuration is requiered to use them.

Each individual plugin can be disabled, replaced or used with other plugins in the package.json:

{
  "release": {
    "verifyConditions": ["@semantic-release/npm", "verify-other-condition"],
    "getLastRelease": "custom-get-last-release",
    "publish": ["@semantic-release/npm", "custom-publish"]
  }
}

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 github plugin:

{
  "release": {
    "verifyConditions": ["@semantic-release/npm", "@semantic-release/git", "@semantic-release/github"],
    "getLastRelease": "@semantic-release/git",
    "publish": [
      {
        "path": "@semantic-release/npm",
        "npmPublish": false,
        "tarballDir": "dist"
      },
      {
        "path": "@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 git plugin:

{
  "release": {
    "verifyConditions": ["@semantic-release/npm", "@semantic-release/git"],
    "getLastRelease": "@semantic-release/npm",
    "publish": [
      {
        "path": "@semantic-release/npm",
        "pkgRoot": "dist"
      },
      {
        "path": "@semantic-release/git",
        "assets": ["package.json", "npm-shrinkwrap.json"]
      },
    ]
  },
  "scripts": {
    "postpublish": "cp -r dist/package.json . && cp -r dist/npm-shrinkwrap.json ."
  }
}
