electron-packager vs WiX Toolset

electron-packager bundles Electron app source code with a renamed Electron executable and supporting files into folders ready for distribution. It works as a command-line tool or a Node.js library called through JavaScript. Packager can find or download a matching Electron release and build for a selected platform and architecture, all valid combinations, or the host combination. Output targets include Windows, macOS—including Mac App Store targets—and Linux; these are also the listed host platforms. Documented target architectures include x86, x86_64, arm64, universal macOS, Linux armv7l, and Linux mips64el, though some depend on Electron versions. CLI options include a regular-expression ignore filter for files and folders. Electron Forge uses Packager internally, and installer tools can use its output folders to create distributables. The free, open-source Node.js tool requires Node.js 22.12.0 or higher, and local installation is recommended. Signing a macOS or Mac App Store bundle requires building on a macOS host. The project also notes that even a minimal zipped app is approximately the size of the matching zipped Electron binary.
