What is the proper way to implement commandline support in an electron app without showing the gui, but executing the code and closing the application?

I couldn't find any samples online of a proper way to implement this. I was wondering if i should replace the app.on("ready", createWindow); with a different method like init() that checks if there are any commandline args otherwise proceed as normal like the following...

import { app, BrowserWindow, nativeTheme } from "electron";
import path from "path";

let mainWindow;

function createWindow() {
  /**
   * Initial window options
   */
  console.log("running application....");
  mainWindow = new BrowserWindow({
    width: 1000,
    height: 960,
    useContentSize: true,
    webPreferences: {
      contextIsolation: true,
      enableRemoteModule: true,
      preload: path.resolve(__dirname, process.env.QUASAR_ELECTRON_PRELOAD),
    },
  });

  mainWindow.loadURL(process.env.APP_URL);

  if (process.env.DEBUGGING) {
    // if on DEV or Production with debug enabled
    mainWindow.webContents.openDevTools();
  } else {
    // we're on production; no access to devtools pls
    mainWindow.webContents.on("devtools-opened", () => {
      mainWindow.webContents.closeDevTools();
    });
  }

  mainWindow.on("closed", () => {
    mainWindow = null;
  });
}

function processArgs() {
  console.log("running commandline....");
}

app.on("ready", createWindow); // REPLACE createWindow with init method that checks and then calls createWindow is no args are supplied?

app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", () => {
  if (mainWindow === null) {
    createWindow();
  }
});
