# Delete Package Versions

This action deletes versions of a package from [GitHub Packages](https://github.com/features/packages). This action will only delete a maximum of 100 versions in one run.

### What It Can Do

* Create a retention policy (delete all except n most recent pre-release versions)
* Delete all package versions except n most recent versions
* Delete oldest version(s)
* Ignore version(s) from deletion through regex
* Delete version(s) of a package that is hosted from a repo having access to package
* Delete version(s) of a package that is hosted from a repo not having access to package
* Delete a single version
* Delete multiple versions
* Delete specific version(s)

# Usage

```yaml
- uses: actions/delete-package-versions@v4
  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 package.
  # Defaults to the owner of the repo executing the workflow.
  # Required if deleting a version from a package hosted in a different org than the one executing the workflow.
  owner:

  # Name of the package.
  # Required
  package-name:

  # Type of the package. Can be one of container, maven, npm, nuget, or rubygems.
  # Required
  package-type:

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

  # The number of latest versions to keep.
  # This cannot be specified with `num-old-versions-to-delete`. By default, `min-versions-to-keep` takes precedence over `num-old-versions-to-delete`.
  # When set to 0, all deletable versions will be deleted.
  # When set greater than 0, all deletable package versions except the specified number will be deleted.
  min-versions-to-keep:

  # The package versions to exclude from deletion.
  # Takes regex for the version name as input.
  # By default nothing is ignored. This is ignored when `delete-only-pre-release-versions` is true
  ignore-versions:

  # If true it will delete only the pre-release versions.
  # The number of pre-release versions to keep can be set by using `min-versions-to-keep` value with this.
  # When `min-versions-to-keep` is 0, all pre-release versions get deleted.
  # Defaults to false.
  # Cannot be used with `num-old-versions-to-delete` and `ignore-versions`.
  delete-only-pre-release-versions:

  # The token used to authenticate with GitHub Packages.
  # Defaults to github.token.
  # Required if the repo running the workflow does not have access to delete the package.
  #   For rubygems and maven package, repo has access if package is hosted in the same repo as the workflow.
  #   For container, npm and nuget package, repo has access if assigned **Admin** role under Package Settings > Manage Actions Access.
  #   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:
```

# Valid Input Combinations

`owner`, `package-name`, `package-type` and `token` can be used with the following combinations in a workflow - 

  - `num-old-versions-to-delete`
  - `min-versions-to-keep` 
  - `delete-only-pre-release-versions`
  - `ignore-versions`
  - `num-old-versions-to-delete` + `ignore-versions`
  - `min-versions-to-keep` + `ignore-versions`
  - `min-versions-to-keep` + `delete-only-pre-release-versions`

  ### Delete all pre-release versions except y latest pre-release package versions

  To delete all pre release versions except y latest pre-release package versions, the __package-name__, __min-versions-to-keep__ and __delete-only-pre-release-versions__ inputs are required.

  __Example__

  Delete all pre-release package versions except latest 10

  ```yaml
  - uses: actions/delete-package-versions@v4
    with: 
      package-name: 'test-package'
      package-type: 'npm'
      min-versions-to-keep: 10
      delete-only-pre-release-versions: "true"
  ```
  To delete all pre release versions except y latest pre-release package versions from a repo not having access to package, the __owner__, __package-name__, __token__, __min-versions-to-keep__ and __delete-only-pre-release-versions__ inputs are required.

  __Example__

  Delete all pre-release package versions except latest 10 from a repo not having access to package

  ```yaml
  - uses: actions/delete-package-versions@v4
    with: 
      owner: 'github'
      package-name: 'test-package'
      package-type: 'npm'
      token: ${{ secrets.GITHUB_PAT }}
      min-versions-to-keep: 10
      delete-only-pre-release-versions: "true"
  ```

  ### Delete all except y latest versions while ignoring particular package versions

  To delete all except y latest versions while ignoring particular package versions, the __package-name__, __min-versions-to-keep__ and __ignore-versions__ inputs are required.

  __Example__

  Delete all except latest 3 package versions excluding major versions as per semver

  ```yaml
  - uses: actions/delete-package-versions@v4

      package-type: 'npm'
      min-versions-to-keep: 3
      ignore-versions: '^(0|[1-9]\\d*)\\.0\\.0$'
  ```

  To delete all except y latest versions while ignoring particular package versions from a repo not having access to package, the __owner__, __package-name__, __token__, __min-versions-to-keep__ and __ignore-versions__ 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__

  Delete all except latest 3 package versions excluding major versions as per semver from a repo not having access to package

  ```yaml
