This GitHub Action (written in JavaScript) wraps the GitHub Release API, specifically the Upload a Release Asset endpoint, to allow you to leverage GitHub Actions to upload release assets.

GitHub Actions status



Create a workflow .yml file in your repositories .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file. You also will need to have a release to upload your asset to, which could be created programmatically by @actions/create-release as show in the example workflow.


For more information on these inputs, see the API Documentation

  • upload_url: The URL for uploading assets to the release, which could come from another GitHub Action, for example the @actions/create-release GitHub Action


For more information on these outputs, see the API Documentation for an example of what these outputs look like

  • id: The ID of the asset
  • browser_download_url: The URL users can navigate to in order to download the release asset. i.e.

Example workflow - upload a release asset

On every push to a tag matching the pattern v*, create a release and upload a release asset. This Workflow example assumes you have the @actions/create-release Action in a previous step:

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

name: Upload Release Asset

    name: Upload Release Asset
    runs-on: ubuntu-latest
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build project # This would actually build your project, using zip for an example artifact
        run: |
          zip --junk-paths my-artifact
      - name: Create Release
        id: create_release
        uses: actions/create-release@v1
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          draft: false
          prerelease: false
      - name: Upload Release Asset
        id: upload-release-asset 
        uses: actions/upload-release-asset@v1
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          upload_url: ${{ steps.create_release.outputs.upload_url }} # This pulls from the CREATE RELEASE step above, referencing it's ID to get its outputs object, which include a `upload_url`. See this blog post for more info: 
          asset_path: ./
          asset_content_type: application/zip

This will upload a release artifact to an existing release, outputting the browser_download_url for the asset which could be handled by a third party service, or by GitHub Actions for additional uses. For more information, see the GitHub Documentation for the upload a release asset endpoint.
