    Traditional MSI Installers

    Most Electron developers use the official windows-installer to create Windows installers. It does not require Administrator privileges and comes bundled with an automatic updater. If your app targets consumers, it will likely be the better choice.

    However, if you need to create a traditional MSI the way Microsoft intended for software to be installed, this module is your friend. It creates a standalone MSI that installs your application to Program Files or any user-defined directory, much like the installers for Office, Node.js, or other popular apps. It allows up- and downgrades. For more details, see: Should I use this?

    Prerequisites

    Before using this module, make sure to install the Wix toolkit v3. Only the command line tools are required. If you are using AppVeyor or another Windows CI system, it is likely already installed.

    npm i --save-dev electron-wix-msi
    

    Whats new?

    Version 3 is a major release for this toolkit. Many internals were reworked and V3 delivers improvements listed below. Please look out for the **🆕 icon throughout this documentation for new parameter.

    New install folder structure

    A new folder structure allows to update the MSI installation while your app is running without temporarily corrupting the installation. If files are locked during an update then the MSI engine schedules file operation after the next reboot. While files that are not locked will be overwritten immediately. That can cause unexpected behavior of your app. The version-based folder structure avoids these problems and leads to a more robust user experience.

    C:\Program Files\
    └─ Kittens
         └─ app-x.x.x // version of the MSI
         └─ .installInfo // contains information about the installation
         └─ kittens.exe // stub executable that launches the newest version
         └─ Update.exe // optional auto updater 

    Auto launch feature

    Auto updating was a long missing feature for MSIs. No more!. The integration of special Squirrel.Windows version allows us to enable auto-updating. This feature is optional and can be enabled/disabled at package time, install time and can even be controlled at run time of your App. See end user documentation

    Auto update feature

    Auto updating was a long missing feature for MSIs. No more! The integration of a special Squirrel.Windows version allows us to enable auto-updating. This feature is completely optional and can be enabled/disabled at package time, install time and can even be controlled at run time of your App.

    Desktop shortcut

    Your App will now also have a shortcut on the Desktop.

    Usage

    Creating an installer is a three-step process:

    import { MSICreator } from 'electron-wix-msi';
    
    // Step 1: Instantiate the MSICreator
    const msiCreator = new MSICreator({
      appDirectory: '/path/to/built/app',
      description: 'My amazing Kitten simulator',
      exe: 'kittens',
      name: 'Kittens',
      manufacturer: 'Kitten Technologies',
      version: '1.1.2',
      outputDirectory: '/path/to/output/folder'
    });
    
    // Step 2: Create a .wxs template file
    const supportBinaries = await msiCreator.create();
    
    // 🆕 Step 2a: optionally sign support binaries if you
    // sign you binaries as part of of your packaging script
    supportBinaries.forEach(async (binary) => {
      // Binaries are the new stub executable and optionally
      // the Squirrel auto updater.
      await signFile(binary);
    });
    
    // Step 3: Compile the template to a .msi file
    await msiCreator.compile();
