This works well on my mac and windows. Can't get it to work on a linux sadly.

To pass the arguments to the wrapped node.js script, add this after settings the args:

var processArgs = process.argv.splice(2);
args = args.concat(processArgs);

To pass on the exit code of the wrapper process, add this at the end:

app.on('close', (code) => {
	process.exit(code);
});
