A Node.js module for sending notifications on native Mac, Windows (post and pre 8) and Linux (or Growl as fallback)


A Node.js module for sending cross platform system notifications. Using Notification Center for Mac, notify-osd/libnotify-bin for Linux, Toasters for Windows 8/10, or taskbar Balloons for earlier Windows versions. If none of these requirements are met, Growl is used.

Show a native notification on Mac, Windows, Linux:

const notifier = require('node-notifier');
// String 
// Object 
  'title': 'My notification',
  'message': 'Hello, there!'
  • Mac OS X: >= 10.8 or Growl if earlier.
  • Linux: notify-osd or libnotify-bin installed (Ubuntu should have this by default)
  • Windows: >= 8, task bar balloon if earlier or Growl if that is installed.
  • General Fallback: Growl

Growl takes precedence over Windows balloons.

See documentation and flow chart for reporter choice

$ npm install --save node-notifier

Standard usage, with cross-platform fallbacks as defined in the reporter flow chart. All of the options below will work in a way or another on all platforms.

const notifier = require('node-notifier');
const path = require('path');
  title: 'My awesome title',
  message: 'Hello from node, Mr. User!',
  icon: path.join(__dirname, 'coulson.jpg'), // Absolute path (doesn't work on balloons) 
  sound: true, // Only Notification Center or Windows Toasters 
  wait: true // Wait with callback, until user action is taken against notification 
}, function (errresponse) {
  // Response is response from notification 
notifier.on('click', function (notifierObjectoptions) {
  // Triggers if `wait: true` and user clicks notification 
notifier.on('timeout', function (notifierObjectoptions) {
  // Triggers if `wait: true` and notification closes 

You can also specify what reporter you want to use if you want to customize it or have more specific options per system. See documentation for each reporter below.


const NotificationCenter = require('node-notifier/notifiers/notificationcenter');
new NotificationCenter(options).notify();
const NotifySend = require('node-notifier/notifiers/notifysend');
new NotifySend(options).notify();
const WindowsToaster = require('node-notifier/notifiers/toaster');
new WindowsToaster(options).notify();
const Growl = require('node-notifier/notifiers/growl');
new Growl(options).notify();
const WindowsBalloon = require('node-notifier/notifiers/balloon');
new WindowsBalloon(options).notify();

Or if you are using several (or you are lazy): (note: technically, this takes longer to require)

const nn = require('node-notifier');
new nn.NotificationCenter(options).notify();
new nn.NotifySend(options).notify();
new nn.WindowsToaster(options).notify(options);
new nn.WindowsBalloon(options).notify(options);
new nn.Growl(options).notify(options);

Same usage and parameter setup as terminal-notifier.

Native Notification Center requires Mac OS X version 10.8 or higher. If you have an earlier version, Growl will be the fallback. If Growl isn't installed, an error will be returned in the callback.

Wrapping around terminal-notifier, you can do all terminal-notifier can do through properties to the notify method. E.g. if terminal-notifier says -message, you can do {message: 'Foo'}, or if terminal-notifier says -list ALL, you can do {list: 'ALL'}. Notification is the primary focus for this module, so listing and activating do work, but isn't documented.

const NotificationCenter = require('node-notifier').NotificationCenter;
var notifier = new NotificationCenter({
  withFallback: false, // Use Growl Fallback if <= 10.8 
  customPath: void 0 // Relative path if you want to use your fork of terminal-notifier 
  'title': void 0,
  'subtitle': void 0,
  'message': void 0,
  'sound': false, // Case Sensitive string for location of sound file, or use one of OS X's native sounds (see below) 
  'icon': 'Terminal Icon', // Absolute Path to Triggering Icon 
  'contentImage': void 0, // Absolute Path to Attached Image (Content Image) 
  'open': void 0, // URL to open on Click 
  'wait': false // Wait for User Action against Notification 
}, function(errorresponse) {

For Mac OS notifications, icon and contentImage requires OS X 10.9.

Sound can be one of these: Basso, Blow, Bottle, Frog, Funk, Glass, Hero, Morse, Ping, Pop, Purr, Sosumi, Submarine, Tink. If sound is simply true, Bottle is used.

See specific Notification Center example.

Note: There are some limitations for images in native Windows 8 notifications: The image must be a PNG image, and cannot be over 1024x1024 px, or over over 200Kb. You also need to specify the image by using an absolute path. These limitations are due to the Toast notification system. A good tip is to use something like path.join or path.delimiter to have cross-platform pathing.

Windows 10 Note: You might have to activate banner notification for the toast to show.

From mikaelbr/gulp-notify#90 (comment)

You can make it work by going to System > Notifications & Actions. The 'toast' app needs to have Banners enabled. (You can activate banners by clicking on the 'toast' app and setting the 'Show notification banners' to On)

toaster is used to get native Windows Toasts!

const WindowsToaster = require('node-notifier').WindowsToaster;
var notifier = new WindowsToaster({
  withFallback: false, // Fallback to Growl or Balloons? 
  customPath: void 0 // Relative path if you want to use your fork of toast.exe 
  title: void 0,
  message: void 0,
  icon: void 0, // Absolute path to Icon 
  sound: false, // true | false. 
  wait: false, // Wait for User Action against Notification 
}, function(errorresponse) {
const Growl = require('node-notifier').Growl;
var notifier = new Growl({
  name: 'Growl Name Used', // Defaults as 'Node' 
  host: 'localhost',
  port: 23053
  title: 'Foo',
  message: 'Hello World',
  icon: fs.readFileSync(__dirname + "/coulson.jpg"),
  wait: false, // Wait for User Action against Notification 
  // and other growl options like sticky etc. 
  sticky: false,
  label: void 0,
  priority: void 0

See more information about using growly.

For earlier Windows versions, the taskbar balloons are used (unless fallback is activated and Growl is running). For balloons, a great project called notifu is used.

const WindowsBalloon = require('node-notifier').WindowsBalloon;
var notifier = new WindowsBalloon({
  withFallback: false, // Try Windows Toast and Growl first? 
  customPath: void 0 // Relative path if you want to use your fork of notifu 
  title: void 0,
  message: void 0,
  sound: false, // true | false. 
  time: 5000, // How long to show balloon in ms 
  wait: false, // Wait for User Action against Notification 
}, function(errorresponse) {

See full usage on the project homepage: notifu.

Note: notify-send doesn't support the wait flag.

const NotifySend = require('node-notifier').NotifySend;
var notifier = new NotifySend();
  title: 'Foo',
  message: 'Hello World',
  icon: __dirname + "/coulson.jpg",
  // .. and other notify-send flags: 
  urgency: void 0,
  time: void 0,
  category: void 0,
  hint: void 0,

See flags and options on the man pages

You can also use node-notifier as a CLI (as of v4.2.0).

$ notify -h
# notify 
## Options 
   * --help (alias -h)
   * --title (alias -t)
   * --subtitle (alias -st)
   * --message (alias -m)
   * --icon (alias -i)
   * --sound (alias -s)
   * --open (alias -o)
## Example 
   $ notify -t "Hello" -m "My Message" -s --open
   $ notify -t "Agent Coulson" --icon -m "Well, that's new. "
   $ notify -m "My Message" -s Glass
   $ echo "My Message" | notify -t "Hello"

You can also pass message in as stdin:

➜ echo "Message" | notify
# Works with existing arguments
➜ echo "Message" | notify -"My Title"
➜ echo "Some message" | notify -"My Title" -s

node-notifier is made possible through Open Source Software. A very special thanks to all the modules node-notifier uses.

When using node-notifier within a tmux session, it can cause a hang in the system. This can be solved by following the steps described in this comment:

See more info here:

If packaging your Electron app as an asar, you will find node-notifier will fail to load. Due to the way asar works, you cannot execute a binary from within an asar. As a simple solution, when packaging the app into an asar please make sure you --unpack the vendor folder of node-notifier, so the module still has access to the notification binaries. To do this, you can do so by using the following command:

asar pack . app.asar --unpack "./node_modules/node-notifier/vendor/**"
