GitHub as a file server

Abuse GitHub unpublicized attachment API to serve a file.

Especially useful for hosting image files that can be referenced in markdown files.

Usage

1. Install

   brew install j178/tap/github-s3
   # or
   go install github.com/j178/github-s3/cmd/github-s3@latest

2. Login to your GitHub account, and obtain cookie named user_session from GitHub web browser session.
3. Run

   export GITHUB_SESSION=<github-user-session>   
   github-s3 <path-to-file>

If you don't want to obtain the cookie manually, you can use github-s3-auto to automatically find the cookie from your web browser session.

go install github.com/j178/github-s3/cmd/github-s3-auto@latest

github-s3-auto <path-to-file>

Use in GitHub Actions

  build:
    runs-on: ubuntu-latest
    steps:
      - name: Upload files to GitHub
        uses: j178/github-s3@v1
        with:
          files: <list-of-paths-to-file>
