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

not mentioned in the previous answers, loadURL returns a promise that resolves at the same time the 'did-finish-load' event is fired; i.e., they're essentially equivalent, except one's a promise, and the other's a callback.
