electronJS / OSX - open file with my application, how to use the Apple event?

Question

My application is an Electron.js app

I type this command in the terminal to open a file with my app:

open "/Users/Bob/Pictures/test.jpg" -a myApp

In my process.argv I get an Apple event, something like '-psn_0_#######', How do I use this event to get the jpg?

Answer 1

On windows you parse process.argv (in the main process) to get the filepath. but on mac you need to listen to the 'open-file' event. This can be done like this:

app.on('will-finish-launching', () => {
    app.on('open-file', (event, path) => {
        // do something
    });
});
