const { BrowserWindow, app, ipcMain, autoUpdater ,Notification, dialog, Menu } = require('electron');
const path = require('path');

let win = null;

let version = app.getVersion()
console.log(version)
autoUpdater.autoDownload = false;
autoUpdater.autoInstallOnAppQuit = true;

const isDev = !app.isPackaged;

function createWindow() {
  win = new BrowserWindow({
    width: 1200,
    height: 800,
    backgroundColor: "white",
    webPreferences: {
      nodeIntegration: false,
      worldSafeExecuteJavaScript: true,
      contextIsolation: true,
      preload: path.join(__dirname, 'preload.js'),
      sandbox: false
    }
  })

  win.loadFile('index.html');
  if (isDev) win.webContents.openDevTools()
}

if (isDev) {
  const ignoredPattern = /Input|Output|node_modules|[\/\\]\./;
  require('electron-reload')(__dirname, {
    electron: path.join(__dirname, 'node_modules', '.bin', 'electron'),
    ignored: ignoredPattern
  })
}

const template = [
  {
    id: "home",
    label: "Home",
    submenu: [
      {
        label: `Current Version v${app.getVersion()}`,
        click: async() => {

      click() {
        app.quit();
        }
      }
    ]
  }
]

//if mac add empty object to menuTemplate
if (process.platform == "darwin") {
  template.unshift({ label: "" }); //adding it to the beggining of the array
}

const menu = Menu.buildFromTemplate(template);
Menu.setApplicationMenu(menu);

ipcMain.on('notify', (_, message) => {
  new Notification({ title: 'Notifiation', body: message }).show();
})

ipcMain.handle('get-app-path', () => {
  return app.getAppPath();
});


app.whenReady().then( () => { createWindow() })

const url = `${server}/update/${process.platform}/${app.getVersion()}`

autoUpdater.setFeedURL({ url })

setInterval(() => {
  autoUpdater.checkForUpdates()
}, 1000)

autoUpdater.on('update-available', (info) => {
  new Notification({ title: 'Notifiation', body: info }).show();
  dialog.showMessageBox({

    message: `Current version ${app.getVersion()} .A new update is available. Do you want to download and install it now?`,
    buttons: ['Yes', 'No'],
  }).then((result) => {
    if(result.response === 0) {
      let la = template2[0];
      la.submenu[0].label = 'Downloading latest version';
      autoUpdater.downloadUpdate();
    }
  });
    // autoUpdater.downloadUpdate();
});
