What is node-notifier?
The node-notifier package is a Node.js module for sending native notifications on different platforms like Windows, Mac, and Linux. It provides an easy-to-use API to show system notifications using the native notification system of the operating system.
What are node-notifier's main functionalities?
Cross-platform notifications
This feature allows you to send desktop notifications across different operating systems. The code sample shows how to send a simple notification with a title and a message.
const notifier = require('node-notifier');
notifier.notify({
title: 'My notification',
message: 'Hello, this is a notification!'
});
Notification actions
This feature allows you to listen for user interactions with the notification, such as clicking on it. The code sample demonstrates how to handle a click event on the notification.
const notifier = require('node-notifier');
notifier.notify({
title: 'My notification',
message: 'Click to perform an action',
wait: true
}, (err, response, metadata) => {
if (metadata.activationType === 'clicked') {
console.log('Notification clicked!');
}
});
Custom notification sound
This feature allows you to customize the notification sound and appearance. The code sample shows how to send a notification with a custom sound and icon.
const notifier = require('node-notifier');
notifier.notify({
title: 'My notification',
message: 'With a custom sound!',
sound: true, // Only Notification Center or Windows Toasters
appIcon: '/path/to/icon.png', // Absolute path (doesn't work on balloons)
contentImage: '/path/to/image.png' // Absolute Path to Attached Image (Content Image)
});
Other packages similar to node-notifier
electron-notifications
A package specifically designed for Electron applications to show desktop notifications. It is similar to node-notifier but tailored for the Electron environment, which means it might not be suitable for non-Electron Node.js applications.
pushover-notifications
This package allows you to send notifications using the Pushover service. It differs from node-notifier in that it requires an internet connection and uses the Pushover API to send messages to devices, whereas node-notifier works offline and uses the native OS notification systems.
toastr
Toastr is a Javascript library for non-blocking notifications. It is designed for web applications and provides in-browser notifications as opposed to the system-level notifications provided by node-notifier.
node-notifier

A Node.js module for sending cross platform system notification. Using
Notification Center for Mac, notify-osd for Linux, Toasters for
Windows 8, or lovely taskbar Balloons for earlier Windows versions. If none of
these requirements are met, be it older version of Windows or OS X,
Growl is used.

Easy Usage
Show native notifications on Mac, Windows, Linux or using Growl!
var notifier = require('node-notifier');
notifier.notify({
'title': 'My notification',
'message': 'Hello, there!'
});
Requirements
- Mac OS X: >= 10.8 or Growl if earlier.
- Linux: notify-osd 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
Install
$ npm install --save node-notifier
Cross-Platform Advanced Usage
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.
var notifier = require('node-notifier');
notifier.notify({
title: 'My awesome title',
message: 'Hello from node, Mr. User!',
icon: path.join(__dirname, 'coulson.jpg'),
sound: true,
wait: true
}, function (err, response) {
});
notifier.on('click', function (notifierObject, options) {
});
notifier.on('timeout', function (notifierObject, options) {
});
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.
Example:
var NotificationCenter = require('node-notifier/notifiers/notificationcenter');
new NotificationCenter(options).notify();
var NotifySend = require('node-notifier/notifiers/notifysend');
new NotifySend(options).notify();
var WindowsToaster = require('node-notifier/notifiers/toaster');
new WindowsToaster(options).notify();
var Growl = require('node-notifier/notifiers/growl');
new Growl(options).notify();
var 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)
var 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);
Documentation
Usage NotificationCenter
Same usage and parameter setup as terminal-notifier.
Native Notification Center requires Mac OS X version 10.8 or higher. If you have
earlier versions, Growl will be the fallback. If Growl isn't installed, an error
will be returned in the callback.
Example
It is a wrapper around terminal-notifier, and you can
do all terminal-notifier can do through properties to the notify
method. E.g.
if terminal-notifier
say -message
, you can do {message: 'Foo'}
, or
if terminal-notifier
say -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.
All notification options with their defaults:
var NotificationCenter = require('node-notifier').NotificationCenter;
var notifier = new Notification({
withFallback: false,
customPath: void 0
});
notifier.notify({
'title': void 0,
'subtitle': void 0,
'message': void 0,
'sound': false,
'icon': 'Terminal Icon',
'contentImage': void 0,
'open': void 0,
'wait': false
}, function(error, response) {
console.log(response);
});
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.
Usage WindowsToaster
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 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.
toaster is used to get native Windows Toasts!
var WindowsToaster = require('node-notifier').WindowsToaster;
var notifier = new WindowsToaster({
withFallback: false,
customPath: void 0
});
notifier.notify({
title: void 0,
message: void 0,
icon: void 0,
sound: false,
wait: false,
}, function(error, response) {
console.log(response);
});
Usage Growl
var Growl = require('node-notifier').Growl;
var notifier = new Growl({
name: 'Growl Name Used'
});
notifier.notify({
title: 'Foo',
message: 'Hello World',
icon: fs.readFileSync(__dirname + "/coulson.jpg"),
wait: false,
sticky: false,
label: void 0,
priority: void 0
});
See more information about using
growly.
Usage WindowsBalloon
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.
var WindowsBalloon = require('node-notifier').WindowsBalloon;
var notifier = new WindowsBalloon({
withFallback: false,
customPath: void 0
});
notifier.notify({
title: void 0,
message: void 0,
sound: false,
time: 5000,
wait: false,
}, function(error, response) {
console.log(response);
});
See full usage on the project homepage:
notifu.
Usage NotifySend
Note: notify-send doesn't support the wait flag.
var NotifySend = require('node-notifier').NotifySend;
var notifier = new NotifySend();
notifier.notify({
title: 'Foo',
message: 'Hello World',
icon: __dirname + "/coulson.jpg",
urgency: void 0,
time: void 0,
category: void 0,
hint: void 0,
});

A very special thanks to all the modules node-notifier
uses.
