To change the icon of your desktop app;
1- Design an icon and save it as .png (you can design an icon here).
2-Copy and save the icon in your folder.
3- Update the createWindow function with the following code :
function createWindow () {
// Create the browser window.
win = new BrowserWindow({width:1080, height: 840, minWidth:680,
icon:__dirname + '/iconName.png'})
// and load the index.html of the app.
win.loadURL(url.format({
pathname: path.join(__dirname, 'index.html'),
protocol: 'file:',
slashes: true
}))
- Replace iconName with your icon’s file name.
