node-notifier

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.

README

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');
var path = require('path');

notifier.notify({
  title: 'My awesome title',
  message: 'Hello from node, Mr. User!',
  icon: path.join(__dirname, 'coulson.jpg'), // absolute path (not balloons)
  sound: true, // Only Notification Center or Windows Toasters
  wait: true // wait with callback until user action is taken on notification
}, function (err, response) {
  // response is response from notification
});

notifier.on('click', function (notifierObject, options) {
  // Happens if `wait: true` and user clicks notification
});

notifier.on('timeout', function (notifierObject, options) {
  // Happens 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.

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);

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, // use Growl if <= 10.8?
  customPath: void 0 // Relative path if you want to use your fork of terminal-notifier
});

notifier.notify({
  'title': void 0,
  'subtitle': void 0,
  'message': void 0,
  'sound': false, // Case Sensitive string of sound file (see below)
  'icon': 'Terminal Icon', // Set icon? (Absolute path to image)
  'contentImage': void 0, // Attach image? (Absolute path)
  'open': void 0, // URL to open on click
  'wait': false // if wait for notification to end
}, 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, // Fallback to Growl or Balloons?
  customPath: void 0 // Relative path if you want to use your fork of toast.exe
});

notifier.notify({
  title: void 0,
  message: void 0,
  icon: void 0, // absolute path to an icon
  sound: false, // true | false.
  wait: false, // if wait for notification to end
}, function(error, response) {
  console.log(response);
});

Usage Growl

var Growl = require('node-notifier').Growl;

var notifier = new Growl({
  name: 'Growl Name Used', // Defaults as 'Node'
  host: 'localhost',
  port: 23053
});

notifier.notify({
  title: 'Foo',
  message: 'Hello World',
  icon: fs.readFileSync(__dirname + "/coulson.jpg"),
  wait: false, // if wait for user interaction

  // and other growl options like sticky etc.
  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, // Try Windows 8 and Growl first?
  customPath: void 0 // Relative path if you want to use your fork of notifu
});

notifier.notify({
  title: void 0,
  message: void 0,
  sound: false, // true | false.
  time: 5000, // How long to show balloons in ms
  wait: false, // if wait for notification to end
}, 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",

  // .. 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

CLI

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

$ notify -h
