@semantic-release/github

semantic-release plugin to publish a GitHub release and comment on released Pull Requests/Issues.

Step	Description
`verifyConditions`	Verify the presence and the validity of the authentication (set via environment variables) and the assets option configuration.
`publish`	Publish a GitHub release, optionally uploading file assets.
`addChannel`	Update a GitHub release's `pre-release` field.
`success`	Add a comment to each GitHub Issue or Pull Request resolved by the release and close issues previously open by the `fail` step.
`fail`	Open or update a GitHub Issue with information about the errors that caused the release to fail.

Install

$ npm install @semantic-release/github -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/github", {
      "assets": [
        {"path": "dist/asset.min.css", "label": "CSS distribution"},
        {"path": "dist/asset.min.js", "label": "JS distribution"}
      ]
    }],
  ]
}

With this example GitHub releases will be published with the file dist/asset.min.css and dist/asset.min.js.

Configuration

GitHub authentication

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

Follow the Creating a personal access token for the command line documentation to obtain an authentication token. The token has to be made available in your CI environment via the GH_TOKEN environment variable. The user associated with the token must have push permission to the repository.

When creating the token, the minimum required scopes are:

repo for a private repository
public_repo for a public repository

Note on GitHub Actions: You can use the default token which is provided in the secret GITHUB_TOKEN. However releases done with this token will NOT trigger release events to start other workflows. If you have actions that trigger on newly created releases, please use a generated token for that and store it in your repository's secrets (any other name than GITHUB_TOKEN is fine).
