TypeError: Cannot read property 'whenReady' of undefined

Question

i have a problem with electron.

TypeError: Cannot read property 'whenReady' of undefined

i use node 14.0.1 electron 10.1.2

i run my app "electron:serve": "vue-cli-service electron:serve",

my background.js

const { app, BrowserWindow } = require('electron')
const { server } = require('feature-server-core')

server.start();

function createWindow () {
    // Создаем окно браузера.

    const win = new BrowserWindow({
        width: 1400,
        height: 900,
        minWidth: 1280,
        minHeight: 800,
        closable: true,
        center: true,
        type: "tool",
        titleBarStyle: "hidden",
    })

    win.menuBarVisible = false;
// и загружаем index.html в приложении.
    win.loadURL("google.com")
}

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

    app.on('activate', function () {
        // On macOS it's common to re-create a window in the app when the
        // dock icon is clicked and there are no other windows open.
        if (BrowserWindow.getAllWindows().length === 0) createWindow()
    })
})

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
    if (process.platform !== 'darwin') app.quit()
})

Answer 1

This is the problem related to directly calling the 'index.js' with node like node index.js. You need to use electron index.js or electron .(if your file is index.js) electron is building your app.

Answer 2

npm start
