➖ 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 will handle the rest.

✅ Only one dependency, and one peer-dependency.

✅ Works on macOS, Windows and most Linuxes. See details.

✅ 💥 3.6kB minified + gzipped 💥

Installation

yarn add menubar

Usage

Starting with your own new project, run these commands:

$ yarn add menubar
$ touch myApp.js
$ touch index.html

Fill index.html with some HTML, and myApp.js like this:

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

const mb = menubar();

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

Then use electron to run the app:

$ electron myApp.js

Alternatively, see examples/hello-world folder for a simple working example.

Menubar Class

The return value of menubar() is a Menubar class instance, which has these properties:

• app: the Electron App instance,
• window: the Electron Browser Window instance,
• tray: the Electron 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

See the reference API docs.

menubar() Options

You can pass an optional options object into the menubar({ ... }) function:

• dir (default process.cwd()) - the app source directory
• index (default file:// + opts.dir + index.html) - The URL to load the menubar's browserWindow with. The url can be a remote address (e.g. http://) or a path to a local HTML file using the file:// protocol.
• 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 [e-mail] 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.
• loadUrlOptions - (default undefined) The options passed when loading the index URL in the menubar's browserWindow. Everything browserWindow.loadURL supports is supported; this object is simply passed onto browserWindow.loadURL
• 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'

See the reference API docs.

Events

The Menubar class is an event emitter:

• ready - when menubar's tray icon has been created and initialized, i.e. when menubar is ready to be used. Note: this is different than Electron app's ready event, which happens much earlier in the process
• create-window - the line before new BrowserWindow() is called
• before-load - after create window, before loadUrl (can be used for require("@electron/remote/main").enable(webContents))
• after-create-window - the line after all window init code is done and url was loaded
• 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
• To create a native menu, you can use tray.setContextMenu(contextMenu), and pass this custom tray to menubar: const mb = menubar({ tray });. See this example for more information.
• To avoid a flash when opening your menubar app, you can disable backgrounding the app using the following: mb.app.commandLine.appendSwitch('disable-backgrounding-occluded-windows', 'true');
