Question

When I attempt to open a file with a double click in my Electron app, Argv[1] gives me an unexpected value

When attempting to open a file by double-clicking, I encounter an issue while using electron-packager to build the application for the Mac App Store.

Although I have set up the electron app to launch when a file is double-clicked, it appears that the filename of the opened file is not sent as a command line parameter to the app.

Instead of receiving the requested file path in argv[1], I am getting -psn_0_857362. I had anticipated argv[1] would contain the file path, but this does not seem to be the case.

Below is a simplified version of the code snippet used in main.js:

ipcMain.on(
'getOpenFile',
function( e ) {

    let data = null;

    if ( process.argv.length >= 2 ) {
        data = process.argv[1];
    }

    e.returnValue = data;

}
);

I am puzzled as to why the file path is not being displayed. Is there a limitation imposed by the Mac App Store or is there another step required to enable the expected functionality?

If you are using macOS, it may be necessary to handle the app event known as open-file from the main process like this:

app.on('open-file', (event, path) =>
{
    event.preventDefault();
    console.log(path);
});
