Electron Builder Action

GitHub Action for building and releasing Electron apps

This is a GitHub Action for automatically building and releasing your Electron app using GitHub's CI/CD capabilities. It uses electron-builder to package your app and release it to a platform like GitHub Releases.

GitHub Actions allows you to build your app on macOS, Windows and Linux without needing direct access to each of these operating systems.


  1. Install and configure electron-builder (v22+) in your Electron app. You can read about this in the project's docs or in my blog post.

  2. If you need to compile code (e.g. TypeScript to JavaScript or Sass to CSS), make sure this is done using a build script in your package.json file. The action will execute that script before packaging your app. However, make sure that the build script does not run electron-builder, as this action will do that for you.

  3. Add a workflow file to your project (e.g. .github/workflows/build.yml):

    name: Build/release
    on: push
        runs-on: ${{ matrix.os }}
            os: [macos-latest, ubuntu-latest, windows-latest]
          - name: Check out Git repository
            uses: actions/checkout@v1
          - name: Install Node.js, NPM and Yarn
            uses: actions/setup-node@v1
              node-version: 10
          - name: Build/release Electron app
            uses: samuelmeuli/action-electron-builder@v1
              # GitHub token, automatically provided to the action
              # (No need to define this secret in the repo settings)
              github_token: ${{ secrets.github_token }}
              # If the commit is tagged with a version (e.g. "v1.0.0"),
              # release the app after building
              release: ${{ startsWith(github.ref, 'refs/tags/v') }}



Using this the workflow above, GitHub will build your app every time you push a commit.


When you want to create a new release, follow these steps:

  1. Update the version in your project's package.json file (e.g. 1.2.3)
  2. Commit that change (git commit -am v1.2.3)
  3. Tag your commit (git tag v1.2.3). Make sure your tag name's format is v*.*.*. Your workflow will use this tag to detect when to create a release
  4. Push your changes to GitHub (git push && git push --tags)

After building successfully, the action will publish your release artifacts. By default, a new release draft will be created on GitHub with download links for your app. If you want to change this behavior, have a look at the electron-builder docs.



You can configure the action further with the following options:

  • package_root: Directory where NPM/Yarn commands should be run (default: ".")
  • build_script_name: Name of the optional NPM build script which is executed before electron-builder (default: "build")
  • skip_build: Whether the action should execute the NPM build script before running electron-builder
  • use_vue_cli: Whether to run electron-builder using the Vue CLI plugin instead of calling the command directly
  • args: Other arguments to pass to the electron-builder command, e.g. configuration overrides (default: "")
  • max_attempts: Maximum number of attempts for completing the build and release step (default: 1)

See action.yml for a list of all possible input variables.

Code Signing

If you are building for macOS, you'll want your code to be signed. GitHub Actions therefore needs access to your code signing certificates:

  • Open the Keychain Access app or the Apple Developer Portal. Export all certificates related to your app into a single file (e.g. certs.p12) and set a strong password
  • Base64-encode your certificates using the following command: base64 -i certs.p12 -o encoded.txt
  • In your project's GitHub repository, go to Settings → Secrets and add the following two variables:
    • mac_certs: Your encoded certificates, i.e. the content of the encoded.txt file you created before
    • mac_certs_password: The password you set when exporting the certificates

Add the following options to your workflow's existing action-electron-builder step:

- name: Build/release Electron app
  uses: samuelmeuli/action-electron-builder@v1
    # ...
    mac_certs: ${{ secrets.mac_certs }}
    mac_certs_password: ${{ secrets.mac_certs_password }}

The same goes for Windows code signing (windows_certs and windows_certs_password secrets).


If you are building/releasing your Linux app for Snapcraft (which is electron-builder's default), you will additionally need to install and sign in to Snapcraft. This can be done using an action-snapcraft step before the action-electron-builder step:

- name: Install Snapcraft
  uses: samuelmeuli/action-snapcraft@v1
  # Only install Snapcraft on Ubuntu
  if: startsWith(matrix.os, 'ubuntu')
    # Log in to Snap Store
    snapcraft_token: ${{ secrets.snapcraft_token }}

You can read here how you can obtain a snapcraft_token.


If you've configured electron-builder to notarize your Electron Mac app as described in this guide, you can use the following steps to let GitHub Actions perform the notarization for you:

  1. Define the following secrets in your repository's settings on GitHub:

    • api_key: Content of the API key file (with the p8 file extension)
    • api_key_id: Key ID found on App Store Connect
    • api_key_issuer_id: Issuer ID found on App Store Connect
  2. In your workflow file, add the following step before your action-electron-builder step:

    - name: Prepare for app notarization
      if: startsWith(matrix.os, 'macos')
      # Import Apple API key for app notarization on macOS
      run: |
        mkdir -p ~/private_keys/
        echo '${{ secrets.api_key }}' > ~/private_keys/AuthKey_${{ secrets.api_key_id }}.p8
  3. Pass the following environment variables to action-electron-builder:

    - name: Build/release Electron app
      uses: samuelmeuli/action-electron-builder@v1
        # ...
        # macOS notarization API key
        API_KEY_ID: ${{ secrets.api_key_id }}
        API_KEY_ISSUER_ID: ${{ secrets.api_key_issuer_id }}


For an example of the action used in production (including app notarization and publishing to Snapcraft), see Mini Diary.
