# Usage

```yaml
- uses: actions/delete-package-versions@v1
  with:
  # Can be a single package version id, or a comma separated list of package version ids.
  # Defaults to an empty string.
  package-version-ids:
  
  # Owner of the repo hosting the package.
  # Defaults to the owner of the repo executing the workflow.
  # Required if deleting a version from a package hosted in a different repo than the one executing the workflow.
  owner:

  # Repo hosting the package.
  # Defaults to the repo executing the workflow.
  # Required if deleting a version from a package hosted in a different repo than the one executing the workflow.
  repo:

  # Name of the package.
  # Defaults to an empty string.
  # Required if `package-version-ids` input is not given.
  package-name:

  # The number of old versions to delete starting from the oldest version.
  # Defaults to 1.
  num-old-versions-to-delete:

  # The token used to authenticate with GitHub Packages.
  # Defaults to github.token.
  # Required if deleting a version from a package hosted in a different repo than the one executing the workflow.
  #   If `package-version-ids` is given the token only needs the delete packages scope.
  #   If `package-version-ids` is not given the token needs the delete packages scope and the read packages scope
  token:
```

### Delete a specific version of a package hosted in the same repo as the workflow

To delete a specific version of a package that is hosted in the same repo as the one executing the workflow the __package-version-ids__ input is required.

Package version ids can be retrieved via the [GitHub GraphQL API][api]

__Example__

```yaml
- uses: actions/delete-package-versions@v1
  with:
    package-version-ids: 'MDE0OlBhY2thZ2VWZXJzaW9uOTcyMDY3'
```

### Delete a specific version of a package hosted in a different repo than the workflow

To delete a specific version of a package that is hosted in a different repo than the one executing the workflow the __package-version-ids__, and __token__ inputs are required.

Package version ids can be retrieved via the [GitHub GraphQL API][api]. 

The [token][token] only needs the delete packages scope. It is recommended [to store the token as a secret][secret]. In this example the [token][token] was stored as a secret named __GITHUB_PAT__.

__Example__

```yaml
- uses: actions/delete-package-versions@v1
  with:
    package-version-ids: 'MDE0OlBhY2thZ2VWZXJzaW9uOTcyMDY3'
    token: ${{ secrets.GITHUB_PAT }}
```

<br>

### Delete multiple specific versions of a package hosted in the same repo as the workflow

To delete multiple specifc versions of a package that is hosted in the same repo that is executing the workflow the __package-version-ids__ input is required. 

The __package-version-ids__ input should be a comma separated string of package version ids. Package version ids can be retrieved via the [GitHub GraphQL API][api].

__Example__

```yaml
- uses: actions/delete-package-versions@v1
  with:
    package-version-ids: 'MDE0OlBhY2thZ2VWZXJzaW9uOTcyMDY3, MDE0OlBhY2thZ2VWZXJzaW9uOTcyMzQ5, MDE0OlBhY2thZ2VWZXJzaW9uOTcyMzUw'
```

```yaml
- uses: actions/delete-package-versions@v1
  with:
    package-name: 'test-package'
```

### Delete oldest version of a package hosted in a different repo than the workflow

To delete the oldest version of a package that is hosted in a different repo than the one executing the workflow the __package-name__, __owner__, __repo__, and __token__ inputs are required.

The [token][token] needs the delete packages and read packages scope. It is recommended [to store the token as a secret][secret]. In this example the [token][token] was stored as a secret named __GITHUB_PAT__.

__Example__

```yaml
- uses: actions/delete-package-versions@v1

    owner: 'github'
    repo: 'packages'
    package-name: 'test-package'
    token: ${{ secrets.GITHUB_PAT }}
```

### Delete oldest x number of versions of a package hosted in the same repo as the workflow

To delete the oldest x number of versions of a package hosted in the same repo that is executing the workflow the __package-name__, and __num-old-versions-to-delete__ inputs are required.

__Example__

Delete the oldest 3 version of a package hosted in the same repo as the workflow

```yaml
- uses: actions/delete-package-versions@v1
  with:

    num-old-versions-to-delete: 3
```

### Delete oldest x number of versions of a package hosted in a different repo than the workflow

To delete the oldest x number of versions of a package hosted in a different repo than the one executing the workflow the __package-name__, __num-old-versions-to-delete__, __owner__, __repo__, and __token__ inputs are required.

The [token][token] needs the delete packages and read packages scope. It is recommended [to store the token as a secret][secret]. In this example the [token][token] was stored as a secret named __GITHUB_PAT__.
