A semantic-release plugin to publish npm packages with Yarn. Comes with built-in support for monorepos.

 {
   "branches": ["main"],
   "plugins": [
     "@semantic-release/commit-analyzer",
     "@semantic-release/release-notes-generator",
-    "@semantic-release/npm",
+    "semantic-release-yarn",
     "@semantic-release/github",
     "@semantic-release/git"
   ]
 }

yarn add --dev semantic-release-yarn

Note: this plugin only works with Yarn 2 and higher.

Use this plugin instead of the default @semantic-release/npm. The plugin must be added in the semantic-release configuration, for example:

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

Providing a NPM access token in your configuration is required and can be set either via environment variables or the .yarnrc.yml file.

Make sure your access token has write access to the package you want to publish:

• When using a classic/legacy token, it must be either:
  • A "Publish" token if you're not using 2FA or if 2FA is disabled for write operations (The "Require two-factor authentication for write actions" is unchecked in your 2FA settings)
  • An "Automation" token if 2FA is enabled for write operations (The "Require two-factor authentication for write actions" is checked in your 2FA settings)
• When using a granular access token make sure it has "Read and write" permissions on the package you want to publish.

Note: only the npmAuthToken is supported. The legacy npmAuthIdent (username:password) authentication is strongly discouraged and not supported by this plugin.

Currently, simple monorepo versioning and publishing is supported. All workspaces versions will be aligned (a.k.a. fixed/locked mode) and when a new release is due, all workspaces will be published to the NPM registry.

Monorepos are detected by the presence of a workspaces option in the root package.json file, for example:

{
  "workspaces": ["packages/*"]
}

You can set the mainWorkspace plugin option to use in notifications of new releases (e.g. in issue and pull request comments made by the @semantic-release/github plugin.

See our roadmap for further implementation status.

Most other Yarn options could be specified as environment variables as well. Just prefix the names and write them in snake case. Refer to the Yarnrc files documentation to see all options.

Note: the configuration set by environment variables will take precedence over configuration set in the .yarnrc.yml file.

Options can also be set in a .yarnrc.yml file. See Yarnrc files for the complete list of option.

The registry can be configured in the package.json and will take precedence over the configuration in environment variables and the .yarnrc.yml file:

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

Note: the @semantic-release/npm plugin supports setting the publishConfig.tag option. However, Yarn 2 doesn't seem to > support this.

These options can be added to the semantic-release configuration, for example:

{
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    [
      "semantic-release-yarn",
      {
        "npmPublish": false
      }
    ],
    "@semantic-release/github"
  ]
}

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

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-yarn",
      {
        "npmPublish": false,
        "tarballDir": "dist"
      }
    ],
    [
      "@semantic-release/github",
      {
        "assets": "dist/*.tgz"
      }
    ]
  ]
}

After cloning this repository, optionally install husky so you never commit incorrectly formatted code:

yarn husky install

• Monorepo support
  • Support for fixed versions
  • Support for private/non-private root package
  • Support for channels
  • Support for release information for each workspace
  • Support for independant versions (probably impossible without custom analyze-commits plugin)
• Get rid of CJS build once upstream PR 2607 lands
• Since we're using the latest AggregateError package, semantic-release is not picking up our error stack and we get a generic error message instead of a well formatted one. Hope this can be fixed once upstream PR #2631 lands
