npm install electron-packager --save-dev

"build":"electron-packager . myapp --platform=all --arch=all --overwrite"

فلگ بعدی معماری سیستم عامل را نشان میدهد که برای سیستم‌های 32 بیتی مقدار ia32 و برای سیستم‌های 64 بیتی مقدار x64 می‌باشد. ولی در صورتیکه همه مقادیر را در نظر دارید، می‌توانید همانند خط بالا از مقدار all استفاده کنید.

در همه حالات بالا اگر فقط تعدادی از آن‌ها را بخواهید وارد کنید، می‌توانید هر عبارت را با , از هم جدا سازید؛ مانند darwin,linux که برای این دو پلتفرم تنها نسخه اجرایی تولید می‌شود.

فلگ آخر اجباری نیست، ولی برای دفعات بعدی بسیار مناسب است. اگر از قبل یک بسته بندی وجود دارد، بسته بندی جدید بر روی قبلی‌ها رونویسی خواهد شد.

حال با دستور زیر در nodejs، عملیات بسته بندی را آغاز می‌کنیم:

npm run build

--ignore=node_modules/<package_name>
یا
--ignore=node_modules/electron_[0-9]*

--version-string.ProductName="Product"

                   Properties supported:
                   - CompanyName
                   - FileDescription
                   - OriginalFilename
                   - ProductName
                   - InternalName

دستور بسته بندی بالا را نیز می‌توان به طور خلاصه‌تر نیز نوشت :

electron-packager . --all

{
   await context.Response.WriteAsync("Hello World!");
