semantic-release-github-pullrequest

This plugin is a plugin for semantic-release.

It automatically creates a pull request containing changes for any files you want to publish in your repository, like release notes of your newly published release.


| Step | Description |
| ------------------ | ------------------------------------------------------------------------------------------------ |
| verifyConditions | Verify that all needed configuration is present. |
| publish | Create a branch to upload all assets and create the pull request on the base branch on GitHub. |

Install

Add the plugin to your npm-project:

``console
npm install semantic-release-github-pullrequest -D
`

Usage

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

`json
{
"plugins": [
"@semantic-release/commit-analyzer",
"@semantic-release/release-notes-generator",
[
"semantic-release-github-pullrequest", {
"assets": ["CHANGELOG.md"],
"baseRef": "main"
}
]
]
}
`

With this example, a GitHub pull request will be created, with the content of CHANGELOG.md file, on the main branch.

Configuration

$3

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_RELEASE or 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 no workflows will be triggered in the Pull Request, providing it to be merged.
You can use GH_TOKEN or GITHUB_TOKEN with the secret _GITHUB_TOKEN_ to create the release, and use GH_TOKEN_RELEASE with this plugin to create the Pull Request.
