Read Windows command line option in Electron renderer process

Question

I have a deployed Electron App in Windows. I'm trying to add a command line option on the .exe.

"C:\Program Files\MyApp.exe" -debug

How I can read the debug flag inside my App? I tried with process.argv, but the debug variable isn't there.

Answer 1

All your arguments are inside the process.argv array. So if you are trying to access the arguments from the main process you can just use the following:

//the command you called is always argv[0]
process.argv[0] == "C:\Program Files\MyApp.exe"

//every other argument, separated by spaces, is in the array in order
process.argv[1] == "-debug"

If you are trying to access them from a renderer process however, you need to use electron remote.

const remote = require('electron').remote

//the command you called is always argv[0]
remote.process.argv[0] == "C:\Program Files\MyApp.exe"

//every other argument, separated by spaces, is in the array in order
remote.process.argv[1] == "-debug"
