# node-notifier [![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependency Status][depstat-image]][depstat-url]

A Node.js module for sending cross platform system notifications. Using
Notification Center for macOS, 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.

![Native Windows Screenshot](https://raw.githubusercontent.com/mikaelbr/node-notifier/master/example/windows.png)

## Input Example macOS Notification Center

![Input Example](https://raw.githubusercontent.com/mikaelbr/node-notifier/master/example/input-example.gif)

## Quick Usage

Show a native notification on macOS, Windows, Linux:

```javascript
const notifier = require('node-notifier');
// String
notifier.notify('Message');

// Object
notifier.notify({
  'title': 'My notification',
  'message': 'Hello, there!'
});
```

## Requirements
- **macOS**: >= 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](./DECISION_FLOW.md)

## Install
```
$ npm install --save node-notifier
```

## Cross-Platform Advanced Usage

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

```javascript
const notifier = require('node-notifier');
const path = require('path');

notifier.notify({
  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 (err, response) {
  // Response is response from notification
});

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

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

Example:
```javascript
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)

```javascript
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);
```

### Usage NotificationCenter

Same usage and parameter setup as [terminal-notifier](https://github.com/alloy/terminal-notifier).

Native Notification Center requires macOS 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.


#### Example

Wrapping around [terminal-notifier](https://github.com/alloy/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.

### All notification options with their defaults:

```javascript
const NotificationCenter = require('node-notifier').NotificationCenter;

var notifier = new NotificationCenter({
  withFallback: false, // Use Growl Fallback if <= 10.8
  customPath: void 0 // Relative/Absolute path to binary if you want to use your own fork of terminal-notifier
});

notifier.notify({
  'title': void 0,
  'subtitle': void 0,
  'message': void 0,
  'sound': false, // Case Sensitive string for location of sound file, or use one of macOS' 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 or times out. Same as timeout = 5 seconds

  // New in latest version. See `example/macInput.js` for usage
  timeout: 5, // Takes precedence over wait if both are defined.
  closeLabel: void 0, // String. Label for cancel button
  actions: void 0, // String | Array<String>. Action label or list of labels in case of dropdown
  dropdownLabel: void 0, // String. Label to be used if multiple actions
  reply: false // Boolean. If notification should take input. Value passed as third argument in callback and event emitter.
}, function(error, response, metadata) {
  console.log(response, metadata);
});
```

**Note:** `wait` option is shorthand for `timeout: 5` and doesn't make the notification sticky, but sets
timeout for 5 seconds. Without `wait` or `timeout` notifications are just fired and forgotten Without
given any response. To be able to listen for response (like activation/clicked), you have to define a timeout.
This is not true if you have defined `reply`. If using `reply` it's recommended to set a high timeout or no timeout at all.

**For macOS notifications, icon and contentImage, and all forms of reply/actions requires macOS 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](./example/advanced.js).

**Custom Path clarification**

`customPath` takes a value of a relative or absolute path to the binary of your fork/custom version of terminal-notifier.

Example: `./vendor/terminal-notifier.app/Contents/MacOS/terminal-notifier`

### 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 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)](https://github.com/mikaelbr/gulp-notify/issues/90#issuecomment-129333034)
> 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)

[Snoretoast](https://github.com/KDE/snoretoast) is used to get native Windows Toasts!

```javascript
const WindowsToaster = require('node-notifier').WindowsToaster;

var notifier = new WindowsToaster({
  withFallback: false, // Fallback to Growl or Balloons?
  customPath: void 0 // Relative/Absolute path if you want to use your fork of SnoreToast.exe
});

notifier.notify({
  title: void 0, // String. Required
  message: void 0, // String. Required if remove is not defined
  icon: void 0, // String. Absolute path to Icon
  sound: false, // Bool | String (as defined by http://msdn.microsoft.com/en-us/library/windows/apps/hh761492.aspx)
  wait: false, // Bool. Wait for User Action against Notification or times out
  id: void 0, // Number. ID to use for closing notification.
  appID: void 0, // String. App.ID. Don't create a shortcut but use the provided app id.
  remove: void 0, // Number. Refer to previously created notification to close.
  install: void 0 // String (path, application, app id).  Creates a shortcut <path> in the start menu which point to the executable <application>, appID used for the notifications.
}, function(error, response) {
  console.log(response);
});
```

### Usage Growl

```javascript
const 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, // 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](https://github.com/theabraham/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](http://www.paralint.com/projects/notifu/) is used.

```javascript
const WindowsBalloon = require('node-notifier').WindowsBalloon;

var notifier = new WindowsBalloon({
  withFallback: false, // Try Windows Toast and Growl first?
  customPath: void 0 // Relative/Absolute 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 balloon in ms
  wait: false, // Wait for User Action against Notification
  type: 'info' // The notification type : info | warn | error
}, function(error, response) {
  console.log(response);
});
```

See full usage on the [project homepage:
notifu](http://www.paralint.com/projects/notifu/).

### Usage NotifySend

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

```javascript
const 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](http://manpages.ubuntu.com/manpages/gutsy/man1/notify-send.1.html)

## Common Issues

### Use inside tmux session

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: https://github.com/julienXX/terminal-notifier/issues/115#issuecomment-104214742

See more info here: https://github.com/mikaelbr/node-notifier/issues/61#issuecomment-163560801


### Within Electron Packaging

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:

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


### Using Webpack

When using node-notifier inside of webpack, you must add the following snippet to your `webpack.config.js`. The reason this is required, is because node-notifier loads the notifiers from a binary, and so a relative file path is needed. When webpack compiles the modules, it supresses file directories, causing node-notifier to error on certain platforms. To fix/workaround this, you must tell webpack to keep the relative file directories, by doing so, append the following code to your `webpack.config.js`

```javascript
node: {
  __filename: true,
  __dirname: true
}
```
