About

It's a library for Electron, NW.js and PWAs, it can be used on a basic website but it's useless ¯\(ツ)/¯

Main features

Compatible with any version of Electron 🎉
Works with Electron, NW.js and probably others 🤷‍♂️
Fully compatible with Progressive Web Apps and Window Controls Overlay 🔥
Works without any dependencies, so it won't break in the next major release of Electron 👀
Very small footprint (< 30 kB) 👣
Options and methods very similar to custom-electron-titlebar 📖

Demo

You can see a demo of this library in a PWA here: https://6c65726f79.github.io/custom-titlebar/

Notes:

Check the list of compatible browsers.
If the install button doesn't appear, try reloading and reopening the tab several times.
You may need to manually enable Window Controls Overlay until Chrome 98 is released: chrome://flags/#enable-desktop-pwas-window-controls-overlay

Inpiration

This package is highly inspired by custom-electron-titlebar.

Motivations

I needed a custom titlebar for Electron 14 to replace the unmaintained custom-electron-titlebar, but I couldn't find any interesting ones, so I made it myself.

Not yet implemented

~~MenuItem role, icon, radio~~ Done!
~~Icons theme~~ Done!
Submenu scrollbar
Keyboard controls

Q&A

Can I use this package without `@electron/remote`?

Absolutely! Check out the advanced examples to see how it's done.

How to fix Content Security Policy errors?

Simply add style-src 'unsafe-inline' in the Content-Security-Policy meta tag.

How long before this package becomes unmaintained too?

This package doesn't rely on the Electron or NW.js API so it doesn't need as much maintenance as other packages. Even if I stop maintaining it and the API change dramatically, you could modify your code to match the new API. So theoretically this package can't become obsolete.

Methods

getMenuItemById

Returns the MenuItem with the specified id.

const titlebar = new Titlebar({
  menu: [{label: 'Item 1', id: 'item1'}]
});

const menuItem = titlebar.getMenuItemById('item1');

console.log(menuItem.label); // Item 1

updateOptions

This method updates all parameters that are specified.

titlebar.updateOptions({
  menu: Menu.getApplicationMenu(),
  condensed: 'true',
  titleHorizontalAlignment: 'left'
});

updateTitle

This method update the title of the titlebar. If you change the content of the title tag, you should call this method to update the title.

document.title = 'My new title';
titlebar.updateTitle();

// Or you can do as follows and avoid writing document.title
titlebar.updateTitle('New Title');

updateMenu

Deprecated: This method will be removed in v1.0.0, use updateOptions instead.

This method updates or creates the menu. You can use an array of MenuItem from Electron/NW.js, or directly Menu.getApplicationMenu() in Electron.

// With a menu template
const menu = [
  {
    label: 'Item 1',
    submenu: [
      {
        label: 'Subitem 1',
        click: () => console.log('Clicked on subitem 1')
      },
      {
        type: 'separator'
      },
      {
        label: 'Subitem 2',
        click: () => console.log('Clicked on subitem 2')
      },
    ]
  },
  {
    label: 'Item 2',
    submenu: [
      {
        label: 'Subitem checkbox',
        type: 'checkbox',
        checked: true
      },
      {
        type: 'separator'
      },
      {
        label: 'Subitem with submenu',
        submenu: [
          {
            label: 'Submenu item 1',
            accelerator: 'Ctrl+T'
          }
        ]
      }
    ]
  }
];
titlebar.updateMenu(menu);

// Or with getApplicationMenu in Electron
titlebar.updateMenu(Menu.getApplicationMenu());

// Disable menu
titlebar.updateMenu();

dispose

This method removes the titlebar completely and all recorded events.

titlebar.dispose();
