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

let win  

const createWindow = ()=> { 
    win = new BrowserWindow({
        width:800,
        height: 600,
        resizable: false   })
 
     win.loadFile('index.html')
 }  

app.whenReady().then(createWindow)

Then when I run I say electron main.js in the terminal and it takes for ever to load my window
