Artifacts in GitHub actions

Artifacts are data generated by workflows that can be passed to subsequent jobs.

Workflows

Official workflows

The https://github.com/actions/upload-artifact and the https://github.com/actions/download-artifact actions by GitHub for storing and retrieving artifact(s) in the same workflow.

Artifacts across two different workflows

The https://github.com/dawidd6/action-download-artifact action downloads and extracts uploaded artifact(s) associated with a given (different) workflow.

Link to artifacts in pull requests

The https://github.com/tonyhallett/artifacts-url-comments action creates comment(s) in pull request and/or associated issues containing the URL to artifacts from the workflow run being watched.
