Electron Windows Production Bundle Command Line Arguments - windows

Question

I'm building an Electron App using electron-builder on macOS.
In my code I access the command line args like this:
const cmd = electron.remote.app.commandLine;
const val = cmd.hasSwitch('myArg')
? cmd.getSwitchValue('myArg')
: undefined;
This works fine for the production build on macOS when providing the arguments:
./my-electron-app.app/Contents/MacOS/my-electron-app --myArg=foo
// or:
open my-electron-app.app --args -myArg=foo
But on Windows I can't get it working.
Here's what I tried using cmd.exe:
my-electron-app.exe --myArg=foo
my-electron-app.exe -myArg=foo
my-electron-app.exe /myArg=foo
my-electron-app.exe myArg=foo
When logging electron.remote.process.argv[1] I can see the passed arguments on macOS and Windows, but hasSwitch and getSwitchValue won't give me the value.
What am I doing wrong? Or is there a better way to get cross platform command line arguments working?

Answer 1

I'm gonna take a guess that this is because of the capital letters in your switch. See this closed issue:
This is intentional. The hasSwitch API is a direct wrapper of the Chromium CommandLine class, which behaves this way on purpose.
From Chromium source:
Switch names must be lowercase.
Though it's not totally clear to me yet why Mac doesn't suffer from the same problem.
