# upload-pages-artifact

A composite Action for packaging and uploading artifact that can be deployed to [GitHub Pages][pages].

## Usage

See [action.yml](action.yml)

<!-- TODO: document custom workflow -->

## Artifact validation

While using this action is optional, we highly recommend it since it takes care of producing (mostly) valid artifacts.

A Pages artifact must:

- Be called `github-pages`
- Be a single [`gzip` archive][gzip] containing a single [`tar` file][tar]

The [`tar` file][tar] must:

- be under 10GB in size
- not contain any symbolic or hard links
- contain only files and directories

## Release instructions

In order to release a new version of this Action:

1. Locate the semantic version of the [upcoming release][release-list] (a draft is maintained by the [`draft-release` workflow][draft-release]).

2. Publish the draft release from the `main` branch with semantic version as the tag name, _with_ the checkbox to publish to the GitHub Marketplace checked. :ballot_box_with_check:

3. After publishing the release, the [`release` workflow][release] will automatically run to create/update the corresponding the major version tag such as `v0`.

   ⚠️ Environment approval is required. Check the [Release workflow run list][release-workflow-runs].
