but it is not an option. It’s not a tool for packaging programs.
Building an electron program is no different than building it in GTK or QT in the sense that they are just the GUI toolkit and they do not do packaging.
It’s a framework for programs to have their GUI wrapped inside a browser, so they are cross platform.
But electron doesn’t create packages. You can package an electron program using Flatpak, snap, apt, AppImage, pacman, or whatever.
