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.

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

• [require]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
• [require]asset_name : path + filename
• [optional]asset_label : is optionnal for your tagging

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. https://github.com/octocat/Hello-World/releases/download/v1.0.0/latest.installer.exe

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:

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

        with:
          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: https://jasonet.co/posts/new-features-of-github-actions/#passing-data-to-future-steps 
          asset_name: ./latest.installer.exe # path + filename
          asset_label: latest

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.
