Selectize and Electron stop work with webPreferences

Question

I have problem with selectize with Electron framework. It work just fine until I do not include

webPreferences: {
       nodeIntegration: true,
       contextIsolation: false
     }   

then I receive error:

Uncaught TypeError: Cannot read properties of undefined (reading 'fn')

Without this I can not use ipcRenderer. Any idea, or any idea how to communicate with Electron backend without ipcRenderer/ipcMain.

I also use Angular, so code looks like:

 const electron = require('electron');
 const {ipcRenderer} = electron;

function sendAsync(key, message) {
    ipcRenderer.send(key, message);
}

function sendSync(key, message, callback) {
    callback(ipcRenderer.sendSync(key, message));
}

var bdexApp = angular.module('bdexApp', [
    'ui.router',                // Angular flexible routing
    'selectize',
  ]);

And electron part like this:

mainWindow = new BrowserWindow({
     x: config.window.x,
     y: config.window.y,
     width: config.window.width,
     height: config.window.height,
     webPreferences: {
       nodeIntegration: true,
       contextIsolation: false
     }        
   });

Without webPreferences-nodeIntegration and CI, I receive error - require is not defined.
