# GitHub Action - Releases API
This GitHub Action (written in JavaScript) wraps the [GitHub Release API](https://developer.github.com/v3/repos/releases/), specifically the [Create a Release](https://developer.github.com/v3/repos/releases/#create-a-release) endpoint, to allow you to leverage GitHub Actions to create releases.

## Usage
### Pre-requisites
Create a workflow `.yml` file in your repositories `.github/workflows` directory. An [example workflow](#example-workflow---create-a-release) is available below. For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file).

### Inputs
For more information on these inputs, see the [API Documentation](https://developer.github.com/v3/repos/releases/#input)

- `tag_name`: The name of the tag for this release
- `release_name`: The name of the release
- `draft`: `true` to create a draft (unpublished) release, `false` to create a published one. Default: `false`
- `prerelease`: `true` to identify the release as a prerelease. `false` to identify the release as a full release. Default `false`

### Outputs
For more information on these outputs, see the [API Documentation](https://developer.github.com/v3/repos/releases/#response-4) for an example of what these outputs look like

- `id`: The release ID
- `html_url`: The URL users can navigate to in order to view the release. i.e. `https://github.com/octocat/Hello-World/releases/v1.0.0`
- `upload_url`: The URL for uploading assets to the release, which could be used by GitHub Actions for additional uses, for example the [`@actions/upload-release-asset](https://www.github.com/actions/upload-release-asset) GitHub Action

### Example workflow - create a release
On every `push` to a tag matching the pattern `v*`, [create a release](https://developer.github.com/v3/repos/releases/#create-a-release):

```yaml
on:
  push:
    # Sequence of patterns matched against refs/tags
    tags:
      - 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10

name: Create Release

jobs:
  build:
    name: Create Release
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@master
      - name: Create Release
        id: create_release
        uses: actions/create-release@master
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          draft: false
          prerelease: false
```

This will create a [Release](https://help.github.com/en/articles/creating-releases), as well as a [`release` event](https://developer.github.com/v3/activity/events/types/#releaseevent), which could be handled by a third party service, or by GitHub Actions for additional uses, for example the [`@actions/upload-release-asset](https://www.github.com/actions/upload-release-asset) GitHub Action.
