Rename .zip file generated by electron packager - electron

Question

Electron-packager generates folder my-app-win32-x64 but I want this file to be only my-app. I want rest to be removed. I understand electron packager generates .zip file. When this is unzipped it retains the same name.
I tried editing index.js under electron-packager. I am not able to understand this .zip file is generated. So that I can edit the name in which elctron-packager generates this file.
Directory structure:
my-app
/scripts
...
...
/win64
/my-app-win32-x64 //this directory name must be just my-app
my-app.exe
/app
Build script:
"build": "electron-packager --out winx64 --overwrite --platform win32 --appname my-app . --icon=./my_logo.ico --executable-name my-app"

Answer 1

I don't understand how this relates to any ZIP file at all. electron-packager creates a directory structure with an executable, folders, etc., but no ZIP file.
Electron-packager creates a directory {out}/{appname}-win32-x64 where {out} and {appname} are the given command line parameters.
Since you want this output directory to have a different name, you could simply rename it after it's created.
Linux/Mac:
"build": "electron-packager ... && mv win64/my-app-win32-x64 win64/my-app"
Windows:
"build": "electron-packager ... && ren win64\my-app-win32-x64 win64\my-app"
The && runs the second command only if the first one completes successfully (non-zero exit code).
