Menubar

High level way to create menubar desktop applications with Electron.

This module provides boilerplate for setting up a menubar application using Electron. All you have to do is point it at your index.html and menubar icon and this will handle opening/closing a window when you click/blur.

Works on Mac OS, Windows and some Linuxes (Tested on Xfce4, your mileage may vary - patches welcome!).

Mac OS

Windows

Installation

yarn add menubar

Usage

Create a myApp.js like this:

const { menubar } = require('menubar');

const mb = menubar();

mb.on('ready', () => {
  console.log('app is ready');
  // your app code here
});

Make sure there is also a index.html file in the same folder as myApp.js, then use Electron to run the app:

$ electron myApp.js

See the example/ folder for a working example.

The return value of mb is a Menubar class instance, which subclasses EventEmitter and has these additional properties:

{
  app: the electron require('app') instance,
  window: the electron require('browser-window') instance,
  tray: the electron require('tray') instance,
  positioner: the electron-positioner instance,
  setOption(option, value): change an option after menubar is created,
  getOption(option): get an menubar option,
  showWindow(): show the menubar window,
  hideWindow(): hide the menubar window
}

Options

You can pass an optional options object into the menubar constructor:

• dir (default process.cwd()) - the app source directory
• index (default file:// + opts.dir + index.html) - the html to load for the pop up window
• browserWindow - BrowserWindow options to be passed to the BrowserWindow constructor, see Electron docs. Some interesting fields to passed down are:
  • x (default undefined) - the x position of the window
  • y (default undefined) - the y position of the window
  • width (default 400) - window width
  • height (default 400) - window height
  • alwaysOnTop (default false) - if true, the window will not hide on blur
• icon (default opts.dir + IconTemplate.png) - the png icon to use for the menubar. A good size to start with is 20x20. To support retina, supply a 2x sized image (e.g. 40x40) with @2x added to the end of the name, so icon.png and icon@2x.png and Electron will automatically use your @2x version on retina screens.
• tooltip (default empty) - menubar tray icon tooltip text
• tray (default created on-the-fly) - an electron Tray instance. if provided opts.icon will be ignored
• preloadWindow (default false) - Create BrowserWindow instance before it is used -- increasing resource usage, but making the click on the menubar load faster.
• showOnAllWorkspaces (default true) - Makes the window available on all OS X workspaces.
• windowPosition (default trayCenter and trayBottomCenter on Windows) - Sets the window position (x and y will still override this), check positioner docs for valid values.
• showDockIcon (default false) - Configure the visibility of the application dock icon.
• showOnRightClick (default false) - Show the window on 'right-click' event instead of regular 'click'
• width deprecated - Please use options.browserWindow.width, see Electron docs for more info on this field.
• height deprecated - Please use options.browserWindow.height, see Electron docs for more info on this field.
• x deprecated - Please use options.browserWindow.x, see Electron docs for more info on this field.
• y deprecated - Please use options.browserWindow.y, see Electron docs for more info on this field.
• alwaysOnTop deprecated - Please use options.browserWindow.alwaysOnTop, see Electron docs for more info on this field.

Events

The return value of the menubar constructor is an event emitter:

• ready - when the app has been created and initialized
• create-window - the line before new BrowserWindow is called
• after-create-window - the line after all window init code is done
• show - the line before window.show is called
• after-show - the line after window.show is called
• hide - the line before window.hide is called (on window blur)
• after-hide - the line after window.hide is called
• after-close - after the .window (BrowserWindow) property has been deleted
• focus-lost - emitted if always-on-top option is set and the user clicks away

Tips

• Use mb.on('after-create-window', callback) to run things after your app has loaded. For example you could run mb.window.openDevTools() to open the developer tools for debugging, or load a different URL with mb.window.loadUrl()
• Use mb.on('focus-lost') if you would like to perform some operation when using the option browserWindow.alwaysOnTop: true
• To restore focus of previous window after menubar hide, use mb.on('after-hide', () => { mb.app.hide() } ) or similar
