Electron - How to know when renderer window is ready

Question

In my main process I create a renderer window:

var mainWindow = new BrowserWindow({
    height: 600,
    width: 800,
    x: 0,
    y: 0,
    frame: false,
           


        

Answer 1

A listener on "mainWindow" doesn't worked for me. I used instead "mainWindow.webContents".

mainWindow.webContents.once('dom-ready', () => {});
