[node.js] Remove menubar from Electron app

How do I remove this menu-bar from my electron apps:

Also it says "Hello World"(is this because I downloaded electron pre-built, and will go away once I package the application?). I didn't code these into the html, so I don't know how to get it out!-

These solutions has bug. When use solutions at below, windows has delay at closing.

Menu.setApplicationMenu(null),
&&
const updateErrorWindow = new BrowserWindow({autoHideMenuBar: true});

I used solution at below. This is better for now.

const window= new BrowserWindow({...});
window.setMenuBarVisibility(false);

As of 7.0.0, most of the above solutions no longer work. BrowserWindow.setMenu() has been replaced by Menu.setApplicationMenu(), which now changes the menu on all windows. setMenu(), removeMenu() no longer do anything, Which by the way are still mentioned in the docs.

setAutoHideMenuBar() still works, but could be a nuisance if you planned to use Alt as a hotkey modifier. Once menu is visible you have to click away from window (loose focus) to hide menu again.

If your application has more than one window, you can't set/remove menus separately on each window. The only way to remove a menu is to use the frameless window approach. That happens to be what I want in my current application, but not a good solution in all cases.

2020 Update, the only bl**dy thing that worked for me:

Menu.setApplicationMenu(new Menu());

Most of the answers here are not valid for newer versions. With the version of 9.0 or upper, Menu.setApplicationMenu(null); should work. By the way, Menu exported from electron package: const {Menu} = require('electron');

The menu can be hidden or auto-hidden (like in Slack or VS Code - you can press Alt to show/hide the menu).

Relevant methods:

---- win.setMenu(menu) - Sets the menu as the window’s menu bar, setting it to null will remove the menu bar. (This will remove the menu completly)

mainWindow.setMenu(null)

---- win.setAutoHideMenuBar(hide) - Sets whether the window menu bar should hide itself automatically. Once set the menu bar will only
show when users press the single Alt key.

mainWindow.setAutoHideMenuBar(true)

There is also the method for making a frameless window as shown bellow:

(no close button no anything. Can be what we want (better design))

const { BrowserWindow } = require('electron')
let win = new BrowserWindow({ width: 800, height: 600, frame: false })
win.show()

Edit: (new)

win.removeMenu() Linux Windows Remove the window's menu bar.

https://electronjs.org/docs/api/browser-window#winremovemenu-linux-windows

Added win.removeMenu() to remove application menus instead of using win.setMenu(null)

That is added from v5 as per:

https://github.com/electron/electron/pull/16570

https://github.com/electron/electron/pull/16657

Electron v7 bug

For Electron 7.1.1 use Menu.setApplicationMenu instead of win.removeMenu()

as per this thread:
https://github.com/electron/electron/issues/16521

And the big note is: you have to call it before creating the BrowserWindow! Or it will not work!

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

Menu.setApplicationMenu(null);

const browserWindow = new BrowserWindow({/*...*/});

UPDATE (Setting autoHideMenuBar on BrowserWindow construction)

As by @kcpr comment! We can set the property and many on the constructor

That's available on the latest stable version of electron by now which is 8.3!
But too in old versions i checked for v1, v2, v3, v4!
It's there in all versions!

As per this link
https://github.com/electron/electron/blob/1-3-x/docs/api/browser-window.md

And for the v8.3
https://github.com/electron/electron/blob/v8.3.0/docs/api/browser-window.md#new-browserwindowoptions

The doc link
https://www.electronjs.org/docs/api/browser-window#new-browserwindowoptions

From the doc for the option:

autoHideMenuBar Boolean (optional) - Auto hide the menu bar unless the Alt key is pressed. Default is false.

Here a snippet to illustrate it:

let browserWindow = new BrowserWindow({
    width: 800,
    height: 600,
    autoHideMenuBar: true // <<< here
})

@"electron": "^7.1.1" : 

mainWindow = new browserWindow({ height: 500, width: 800});
//mainWindow.setAutoHideMenuBar(true);
mainWindow.autoHideMenuBar = true;

Working as expected without menu in browser.

According to the official documentation @ https://github.com/electron/electron/blob/v8.0.0-beta.1/docs/api/menu.md the proper way to do this now since 7.1.2 and I have tested it on 8.0 as well is to :

const { app, Menu } = require('electron')

Menu.setApplicationMenu(null)

Following the answer from this issue, you must call Menu.setApplicationMenu(null) before the window is created

Use this:

mainWindow = new BrowserWindow({width: 640, height: 360})
mainWindow.setMenuBarVisibility(false)

Reference: https://github.com/electron/electron/issues/1415

I tried mainWindow.setMenu(null), but it didn't work.

For Electron 7.1.1, you can use this:

const {app, BrowserWindow, Menu} = require('electron')
Menu.setApplicationMenu(false)

Before this line at main.js:

mainWindow = new BrowserWindow({width: 800, height: 900})

mainWindow.setMenu(null) //this will r menu bar

setMenu(null); is the best answer, autohidemenu will display on the start of the application

    function createWindow(){
        const win = new BrowserWindow({
            width: 1500,
            height: 800,
            webPreferences:{
                nodeIntergration: true
            }
        });
        win.setMenu(null);
    win.loadFile("index.html");
    }
    app.whenReady().then(createWindow);

When you package your app the default menu won't be there anymore, if this is bugging you during development then you can call setMenu(null) on the browser window as suggested by @TonyVincent.

set autoHideMenuBar to true while creating the browserWindow

mainWindow = new BrowserWindow({
    autoHideMenuBar: true,
    width: 1200,
    height: 800
})
