Semantic Release Action

GitHub Action for Semantic Release.

Usage

Step1: Set any Semantic Release Configuration in your repository.

Step2: Add Secrets in your repository for the Semantic Release Authentication Environment Variables.

Step3: Add a Workflow File to your repository to create custom automated processes.

Basic Usage:

steps:
  - name: Checkout
    uses: actions/checkout@v2
  - name: Semantic Release
    uses: cycjimmy/semantic-release-action@v2
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

IMPORTANT: GITHUB_TOKEN does not have the required permissions to operate on protected branches. If you are using this action for protected branches, replace GITHUB_TOKEN with Personal Access Token. If using the @semantic-release/git plugin for protected branches, avoid persisting credentials as part of actions/checkout@v2 by setting the parameter persist-credentials: false. This credential does not have the required permission to operate on protected branches.

Private Packages

If you are using this action to publish to the npm GitHub Packages Registry, then make sure that you configure this in your package.json file:

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

Inputs

Input Parameter	Required	Description
semantic_version	false	Specify specifying version range for semantic-release. [Details]
branches	false	The branches on which releases should happen.[Details] Support for semantic-release above v16.
branch	false	The branch on which releases should happen.[Details] Only support for semantic-release older than v16.
extra_plugins	false	Extra plugins for pre-install. [Details]
dry_run	false	Whether to run semantic release in dry-run mode. [Details]
extends	false	Use a sharable configuration [Details]

semantic_version

{Optional Input Parameter} Specify specifying version range for semantic-release.
If no version range is specified, latest version will be used by default.

steps:
  - name: Checkout
    uses: actions/checkout@v2
  - name: Semantic Release
    uses: cycjimmy/semantic-release-action@v2
    with:
      semantic_version: 15.13.28  # It is recommended to specify specifying version range
                                  # for semantic-release.
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

It is recommended to manually specify a version of semantic-release to prevent errors caused during the official semantic-release upgrade.

branches

{Optional Input Parameter} The branches on which releases should happen.
branches supports for semantic-release above v16.

steps:
  - name: Checkout
    uses: actions/checkout@v2
  - name: Semantic Release
    uses: cycjimmy/semantic-release-action@v2
    with:
      semantic_version: 16
      # you can set branches for semantic-release above v16.
      branches: |    
        [
          '+([0-9])?(.{+([0-9]),x}).x',
          'master', 
          'next', 
          'next-major', 
          {
            name: 'beta', 
            prerelease: true
          }, 
          {
            name: 'alpha', 
            prerelease: true
          }
        ]
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

branches will override the branches attribute in your configuration file. If the attribute is not configured on both sides, the default is:

[
  '+([0-9])?(.{+([0-9]),x}).x',
  'master', 
  'next', 
  'next-major', 
  {name: 'beta', prerelease: true}, 
  {name: 'alpha', prerelease: true}
]

See configuration#branches for more information.

branch

{Optional Input Parameter} Similar to parameter branches. The branch on which releases should happen.
branch only supports for semantic-release older than v16.

steps:
  - name: Checkout
    uses: actions/checkout@v2
  - name: Semantic Release
    uses: cycjimmy/semantic-release-action@v2
    with:
      semantic_version: 15.13.28
      # you can set branch for semantic-release older than v16.
      branch: your-branch
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

It will override the branch attribute in your configuration file. If the attribute is not configured on both sides, the default is master.

extra_plugins

{Optional Input Parameter} Extra plugins for pre-install.

The action can be used with extra_plugins option to specify plugins which are not in the default list of plugins of semantic release. When using this option, please make sure that these plugins are also mentioned in your semantic release config's plugins array.

For example, if you want to use @semantic-release/git and @semantic-release/changelog extra plugins, these must be added to extra_plugins in your actions file and plugins in your release config file as shown bellow:

Github Action Workflow:

steps:
  - name: Checkout
    uses: actions/checkout@v2
  - name: Semantic Release
    uses: cycjimmy/semantic-release-action@v2
    with:
      # You can specify specifying version range for the extra plugins if you prefer.
      extra_plugins: |
        @semantic-release/[email protected]
        @semantic-release/git
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

Similar to parameter semantic_version. It is recommended to manually specify a version of semantic-release plugins to prevent errors caused.

Release Config:

  plugins: [
    .
+   "@semantic-release/changelog"
+   "@semantic-release/git",
  ]

dry_run

{Optional Input Parameter} Whether to run semantic release in dry-run mode.
It will override the dryRun attribute in your configuration file.

    uses: cycjimmy/semantic-release-action@v2
    with:
      dry_run: true
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

extends
