How to add an icon to electron application

I've got my electron build files for a win .exe and installer but the icons aren't mine. In my main.js file, I have code to attach the icon but I can only make it work inside of the createWindow function. Outside the function, I get an error message. The .exe will run and I get my icon, though it's I get an error in doing so; the installer won't work at all. I've tried going through several tutorials but none of them solve this problem.

main.js

const {app, BrowserWindow, Tray} = require('electron')
const path = require('path')
const url = require('url')

let win

function createWindow () {
  const appIcon = new Tray('icon/app.png')
  win = new BrowserWindow({ width: 1920, height: 1080, icon: 'icon/app.ico' })
  console.log(appIcon, win)
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'app/app.html'),
    protocol: 'file:',
    slashes: true
  }))
  win.on('closed', () => {
    win = null
  })
}

app.on('ready', createWindow)
app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})
app.on('activate', () => {
  if (win === null) {
    createWindow()
  }
})

package.json

{
  "name": "myapp",
  "version": "1.0.0",
  "description": "MyApp",
  "private": true,
  "main": "main.js",
  "build": {
    "appID": "myapp",
    "productName": "MyApp",
    "icon": "icon/app.ico"
  },
  "scripts": {
    "start": "electron ." ,
    "package": "",
  },
  "author": "Me",
  "license": "ISC",
  "devDependencies": {
    "electron": "^1.6.1"
  }
}

I'm not sure what to do from here.

Following worked for me. To display the app icon in the taskbar, you can update the icon on the fly in main.js (if using typescript then main.ts)

win.setIcon(path.join(__dirname, '/src/assets/logo-small.png'));

Worth to mention __dirname points to same directory as package.json

inside the main.js

mainWindow = new BrowserWindow({width: 800, height: 600,icon: __dirname + '/icon.ico'});

and on the installer, if you are using electron-builder

  "devDependencies": {
    "electron": "^1.4.15",
    "electron-builder": "^12.3.1"
  },

make a folder on the root and named build inside that folder add your icon.ico

sometimes you need to restart the electron or build the app 2 times

Simple solution

const nativeImage = require('electron').nativeImage;
    var image = nativeImage.createFromPath(__dirname + '/public/img/logo.png'); 
 // where public folder on the root dir

    image.setTemplateImage(true);


 // Create the browser window.
    win = new BrowserWindow({
        width: 1179,
        height: 754,
        backgroundColor: '#ffffff',
        transparent: false,
        icon: image
    })
