Electron Apps in the Windows Store

Electron-Windows-Store: A CLI that takes the packaged output of your Electron app, then converts it into an AppX package. This allows you to submit your Electron app to the Windows Store 📦. You can also distribute your app as an .appx without using the Windows Store, allowing users to just double-click your .appx to automatically install it.

To install this command line tool, get it directly from npm:

npm install -g electron-windows-store

Then, configure your PowerShell:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

To turn an Electron app into an AppX package, run:

electron-windows-store --input-directory C:\myelectronapp  --output-directory C:\output\myelectronapp --package-version 1.0.0.0 --package-name myelectronapp

This tool supports two methods to create AppX packages: Either using manual file copy operations, or using Windows Containers. The first option requires only the Windows 10 SDK, while the second option also requires the Desktop App Converter.

Usage

Before running the Electron-Windows-Store CLI, let's make sure we have all the prerequisites in place. You will need:

• Windows 10 with at least the Anniversary Update (if your Windows has been updated before 2018, you're good).
• Windows 10 SDK from here
• Node 8 or above (to check, run node -v)

Package Your Electron Application

Package the application using electron-packager (or something similar). Make sure to remove node_modules that you don't need in your final application.

The output should look roughly like this:

├── Ghost.exe
├── LICENSE
├── content_resources_200_percent.pak
├── node.dll
├── pdf.dll
├── resources
│   ├── app
│   └── atom.asar
├── snapshot_blob.bin
├── [... and more files]

Convert with File Copying

From an elevated PowerShell (run it "as Administrator"), run electron-windows-store with the required parameters, passing both the input and output directories, the app's name and version. If you don't pass these parameters, we will simply ask you for them.

electron-windows-store --input-directory C:\myelectronapp  --output-directory C:\output\myelectronapp --package-version 1.0.0.0 --package-name myelectronapp

These are all options for the CLI:

  -h, --help                                 output usage information
  -V, --version                              output the version number
  -c, --container-virtualization             Create package using Windows Container virtualization
  -b, --windows-build                        Display Windows Build information
  -i, --input-directory <path>               Directory containing your application
  -o, --output-directory <path>              Output directory for the appx

  -d, --deploy <true|false>                  Should the app be deployed after creation?
  --identity-name <name>                     Name for identity
  --publisher <publisher>                    Publisher to use (example: CN=developmentca)
  --publisher-display-name <publisherDisplayName> Publisher display name to use
  --make-pri <true|false>                    Use makepri.exe (you don't need to unless you know you do)

  --cert-pass <cert-pass>                    Password to use when signing the application (only necessary if a p12 certication is used)
  --desktop-converter <desktop-converter>    Path to the desktop converter tools
  --expanded-base-image <base-image>         Path to the expanded base image
  --makeappx-params <params>                 Additional parameters for Make-AppXPackage (example: --makeappx-params "/l","/d")
  --signtool-params <params>                 Additional parameters for signtool.exe (example: --makeappx-params "/l","/d")
  --create-config-params <params>            Additional parameters for makepri.exe "createconfig" (example: --create-config-params "/l","/d")')
  --create-pri-params <params>               Additional parameters for makepri.exe "new" (example: --create-pri-params "/l","/d")')
  --verbose <true|false>                     Enable debugging (similar to setting a DEBUG=electron-windows-store environment variable)

Programmatic Usage

You can call this package directly. All options correspond to the CLI options and are equally optional. There is one exception: You can provide a finalSay function, which will be executed right before makeappx.exe is being called. This allows you to modify the output folder right before we turn it into a package.

const convertToWindowsStore = require('electron-windows-store')

convertToWindowsStore({
   containerVirtualization: false,
   inputDirectory: 'C:\\input\\',
   outputDirectory: 'C:\\output\\',
   packageVersion: '1.0.0.0',
   packageName: 'Ghost',
   packageDisplayName: 'Ghost Desktop',
   packageDescription: 'Ghost for Desktops',
   packageExecutable: 'app/Ghost.exe',
   assets: 'C:\\assets\\',
   manifest: 'C:\\AppXManifest.xml',
   deploy: false,
   publisher: 'CN=developmentca',
   windowsKit: 'C:\\windowskit',
   devCert: 'C:\\devcert.pfx',
   certPass: 'abcd',
   desktopConverter: 'C:\\desktop-converter-tools',
   expandedBaseImage: 'C:\\base-image.wim',
   makeappxParams: ['/l'],
   signtoolParams: ['/p'],
   makePri: true,
   createConfigParams: ['/a'],
   createPriParams: ['/b'],
   protocol: "ghost-app",
   finalSay: function () {
     return new Promise((resolve, reject) => resolve())
   }
})

Convert with Container Virtualization

The Desktop App Converter is capable of running an installer and your app during conversion inside a Windows Container. This requires installation of the Desktop App Converter and has more advanced requirements.

⚠️ The vast majority of Electron apps should be packaged using "File Copying". Unless you know that you need your appx to be created using a Windows container, use the "File Copying" method described above.

💻 Ensure that your computer is capable of running containers: You'll need a 64 bit (x64) processor, hardware-assisted virtualization and second Level Address Translation (SLAT). You will also need Windows 10 Enterprise Edition.

💡 Before running the CLI for the first time, you will have to setup the "Windows Desktop App Converter". This will take a few minutes, but don't worry - you only have to do this once. Download and the Desktop App Converter from here. You will receive two files: DesktopAppConverter.zip and BaseImage-14316.wim.

1. Unzip DesktopAppConverter.zip. From an elevated PowerShell (opened with "run as Administrator"., ensure that your systems execution policy allows us to run everything we intended to run by calling Set-ExecutionPolicy bypass.
2. Then, run the installation of the Desktop App Converter, passing in the location of the Windows .ase Image (downloaded as BaseImage-14316.wim), by calling .\DesktopAppConverter.ps1 -Setup -BaseImage .\BaseImage-14316.wim.
3. If running the above command prompts you for a reboot, please restart your machine and run the above command again after a successful restart.

Then, run electron-windows-store with the --container-virtualization flag!

What is the CLI Doing?

Once executed, the tool goes to work: It accepts your Electron app as an input. Then, it archives your application as app.zip. Using an installer and a Windows Container, the tool creates an "expanded" AppX package - including the Windows Application Manifest (AppXManifest.xml) as well as the virtual file system and the virtual registry inside your output folder.

Once we have the expanded AppX files, the tool uses the Windows App Packager (MakeAppx.exe) to create a single-file AppX package from those files on disk. Finally, the tool can be used to create a trusted certificate on your computer to sign the new AppX pacakge. With the signed AppX package, the CLI can also automatically install the package on your machine.

Configuration

💡 The first time you run this tool, it needs to know some settings. It will ask you only once and store your answers in your profile folder in a .electron-windows-store file. You can also provide these values as a parameter when running the CLI.

{
  "publisher": "CN=developmentca",
  "windowsKit": "C:\\Program Files (x86)\\Windows Kits\\10\\bin\\x64",
  "devCert": "C:\\Tools\\DesktopConverter\\Certs\\devcert.pfx",
  "desktopConverter": "C:\\Tools\\DesktopConverter",
  "expandedBaseImage": "C:\\ProgramData\\Microsoft\\Windows\\Images\\BaseImage-14316\\"
}

Using all the fancy Windows APIs

You can pair up your Electron app with a little invisible UWP side-kick, enabling your Electron app to call all WinRT APIs. Check out an example over here.

Devices

The compiled AppX package still contains a win32 executable - and will therefore not run on Xbox, HoloLens, or Phones.
