GitHub Action for [Semantic Release][semantic-url].

## Usage
### Step1: Set any [Semantic Release Configuration](https://github.com/semantic-release/semantic-release/blob/master/docs/usage/configuration.md#configuration) in your repository.

### Step2: [Add Secrets](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets) in your repository for the [Semantic Release Authentication](https://github.com/semantic-release/semantic-release/blob/master/docs/usage/ci-configuration.md#authentication) Environment Variables.

### Step3: Add a [Workflow File](https://help.github.com/en/articles/workflow-syntax-for-github-actions) to your repository to create custom automated processes.

#### Basic Usage:
```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
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](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line). If using the `@semantic-release/git` plugin for protected branches, avoid persisting credentials as part of `actions/checkout@v4` 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][github-packages-registry],
then make sure that you configure this in your `package.json` file:

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

### Inputs
| Input Parameter | Required | Description |
|:-----------------:|:--------:|--------------------------------------------------------------------------------------------------------------------------|
| semantic_version | false | Specify version range for semantic-release. [[Details](#semantic_version)] |
| branches | false | The branches on which releases should happen.[[Details](#branches)]
Support for **semantic-release above v16**. |
| branch | false | The branch on which releases should happen.[[Details](#branch)]
Only support for **semantic-release older than v16**. |
| extra_plugins | false | Extra plugins for pre-install. [[Details](#extra_plugins)] |
| dry_run | false | Whether to run semantic release in `dry-run` mode. [[Details](#dry_run)] |
| ci | false | Whether to run semantic release with CI support. [[Details](#ci)]
Support for **semantic-release above v16**. |
| extends | false | Use a sharable configuration [[Details](#extends)] |
| working_directory | false | Use another working directory for semantic release [[Details](#working_directory)] |
| tag_format | false | Specify format of tag (useful for monorepos) |
| repository_url | false | The Git repository url. If no repository url specified, current repository will be used by default. |

#### semantic_version
> {Optional Input Parameter} Specify version range for semantic-release.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
semantic_version: 19.0.5 # It is recommended to specify a version range
# for semantic-release when using
# semantic-release-action lower than @v4
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```

If no version range is specified with `cycjimmy/semantic-release-action@v4` then [semantic-release](https://github.com/semantic-release/semantic-release/) version [21.1.1](https://github.com/semantic-release/semantic-release/releases/tag/v21.1.1) is used.

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

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
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](https://semantic-release.gitbook.io/semantic-release/usage/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**.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
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](https://semantic-release.gitbook.io/semantic-release/usage/plugins#default-plugins). When using this option, please make sure that these plugins are also mentioned in your [semantic release config's plugins](https://semantic-release.gitbook.io/semantic-release/usage/configuration#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](https://semantic-release.gitbook.io/semantic-release/usage/configuration#configuration-file) as shown bellow:

Github Action Workflow:
```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
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:
```diff
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.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
dry_run: true
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```

#### ci
> {Optional Input Parameter} Whether to run semantic release with CI support (default true).
`ci` supports for **semantic-release above v16**.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
ci: false
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```

`ci` can be used, e.g in combination with `dry_run` when generating the next release version in pull requests, where `semantic_release` would normally block the execution.

#### extends
The action can be used with `extends` option to extend an existing [sharable configuration](https://semantic-release.gitbook.io/semantic-release/usage/shareable-configurations) of semantic-release. Can be used in combination with `extra_plugins`.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
# You can extend an existing shareable configuration.
# And you can specify version range for the shareable configuration if you prefer.
extends: |
@semantic-release/apm-config@^9.0.0
@mycompany/override-config
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```

#### working_directory
This action run semantic release in the github provided workspace by default. You can override it by setting another working directory.

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
# You can select another working directory like a subdirectory for example.
working_directory: ./code
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```

#### tag_format
The default tag format on semantic-release is `v{version}`. You can override that behavior using this option (helpful when you are using monorepos)

```yaml
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Semantic Release
uses: cycjimmy/semantic-release-action@v4
with:
tag_format: custom-v${version}
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
```
