let brWin;

app.on('ready', async () => {

  await new Promise(resolve => session.defaultSession.clearStorageData({storages: ['cookies', 'localstorage', 'cachestorage']}, () => {
    console.log('storages cleared\n');
    resolve();
  }));
  
  brWin = new BrowserWindow({
    width: 1366,
    height: 768,
    webPreferences: {
      nodeIntegration: false,
    },
  });
  
  brWin.webContents.on('did-start-navigation', (event, url, isInPlace, isMainFrame, frameProcessId, frameRoutingId) => {
    if (isMainFrame && !isInPlace)
      console.log('did-start-navigation: %s\n', url);
  });

  brWin.webContents.on('did-navigate', (event, url, httpResponseCode, httpStatusText) => {
    console.log('did-navigate: %i %s\n', httpResponseCode, url);
  });
  
  brWin.webContents.on('did-fail-load', (event, errorCode, errorDescription, validatedURL, isMainFrame, frameProcessId, frameRoutingId) => {
    if (isMainFrame)
