# node-notifier [![NPM version][npm-image]][npm-url] [![Install size][size-image]][size-url] [![Build Status][travis-image]][travis-url]

Send cross platform native notifications using Node.js. Notification Center for macOS,
`notify-osd`/`libnotify-bin` for Linux, Toasters for Windows 8/10, or taskbar balloons for
earlier Windows versions. Growl is used if none of these requirements are met.
[Works well with Electron](#within-electron-packaging).

## Actions Example Windows SnoreToast

![Actions Example](https://raw.githubusercontent.com/mikaelbr/node-notifier/master/example/windows-actions-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 for native notifications, or Growl if earlier.
- **Linux**: `notify-osd` or `libnotify-bin` installed (Ubuntu should have this by default)
- **Windows**: >= 8, or task bar balloons for Windows < 8. Growl as fallback. Growl takes precedence over Windows balloons.
- **General Fallback**: Growl

See [documentation and flow chart for reporter choice](./DECISION_FLOW.md).

## Install

```shell
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 some way or another on most 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, does not apply to Windows Toasters as they always wait or notify-send as it does not support the wait option
  },
  function (err, response, metadata) {
    // Response is response from notification
    // Metadata contains activationType, activationAt, deliveredAt
  }
);

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

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

If you want super fine-grained control, you can customize each reporter individually,
allowing you to tune specific options for different systems.

See below for documentation on each reporter.

**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 reporters (or you're lazy):

```javascript
// 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);
```

### Usage: `NotificationCenter`

Same usage and parameter setup as [**`terminal-notifier`**](https://github.com/julienXX/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

Because `node-notifier` wraps around [**`terminal-notifier`**](https://github.com/julienXX/terminal-notifier),
you can do anything `terminal-notifier` can, just by passing properties to the `notify`
method.

For example:

- if `terminal-notifier` says `-message`, you can do `{message: 'Foo'}`
- if `terminal-notifier` says `-list ALL`, you can do `{list: 'ALL'}`.

Notification is the primary focus of this module, so listing and activating do work,
but they aren'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: undefined // Relative/Absolute path to binary if you want to use your own fork of terminal-notifier
});

notifier.notify(
  {
    title: undefined,
    subtitle: undefined,
    message: undefined,
    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: undefined, // Absolute Path to Attached Image (Content Image)
    open: undefined, // 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: undefined, // String. Label for cancel button
    actions: undefined, // String | Array<String>. Action label or list of labels in case of dropdown
    dropdownLabel: undefined, // 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:** The `wait` option is shorthand for `timeout: 5`. This just sets a timeout
for 5 seconds. It does _not_ make the notification sticky!

As of Version 6.0 there is a default `timeout` set of `10` to ensure that the application closes properly. In order to remove the `timeout` and have an instantly closing notification (does not support actions), set `timeout` to `false`. If you are using `action` it is recommended to set `timeout` to a high value to ensure the user has time to respond.

_Exception:_ If `reply` is defined, it's recommended to set `timeout` to a either
high value, or to nothing at all.

---

**For macOS notifications: `icon`, `contentImage`, and all forms of `reply`/`actions` require 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.

- [Example: input](./example/macInput.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/mac.noindex/terminal-notifier.app/Contents/MacOS/terminal-notifier`

**Spotlight clarification**

`terminal-notifier.app` resides in a `mac.noindex` folder to prevent Spotlight from indexing the app.

### Usage: `WindowsToaster`

**Note:** There are some limitations for images in native Windows 8 notifications:

- The image must be a PNG image
- The image must be smaller than 1024×1024 px
- The image must be less than 200kb
- The image must be specified 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 keep your paths cross-platform.

---

**Windows 10 Fall Creators Update (Version 1709) Note:**

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

The default behaviour is to have the underlying toaster applicaton as `appID`.
This works as expected, but shows `SnoreToast` as text in the notification.

With the Fall Creators Update, Notifications on Windows 10 will only work as
expected if a valid `appID` is specified. Your `appID` must be exactly the same
value that was registered during the installation of your app.

You can find the ID of your App by searching the registry for the `appID` you
specified at installation of your app. For example: If you use the squirrel
framework, your `appID` will be something like `com.squirrel.your.app`.

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

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

notifier.notify(
  {
    title: undefined, // String. Required
    message: undefined, // String. Required if remove is not defined
    icon: undefined, // String. Absolute path to Icon
    sound: false, // Bool | String (as defined by http://msdn.microsoft.com/en-us/library/windows/apps/hh761492.aspx)
    id: undefined, // Number. ID to use for closing notification.
    appID: undefined, // String. App.ID and app Name. Defaults to no value, causing SnoreToast text to be visible.
    remove: undefined, // Number. Refer to previously created notification to close.
    install: undefined // 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: undefined,
  priority: undefined
});
```

See more information about using [growly](https://github.com/theabraham/growly/).

### Usage: `WindowsBalloon`

For earlier versions of Windows, taskbar balloons are used (unless
fallback is activated and Growl is running). The balloons notifier uses a great
project called [**`notifu`**](http://www.paralint.com/projects/notifu/).

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

var notifier = new WindowsBalloon({
  withFallback: false, // Try Windows Toast and Growl first?
  customPath: undefined // Relative/Absolute path if you want to use your fork of notifu
});

notifier.notify(
  {
    title: undefined,
    message: undefined,
    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',

  wait: false, // Defaults no expire time set. If true expire time of 5 seconds is used
  timeout: 10, // Alias for expire-time, time etc. Time before notify-send expires. Defaults to 10 seconds.

  // .. and other notify-send flags:
  'app-name': 'node-notifier',
  urgency: undefined,
  category: undefined,
  hint: undefined
});
```

See flags and options on the man page [`notify-send(1)`](http://manpages.ubuntu.com/manpages/gutsy/man1/notify-send.1.html)

## Common Issues

### Windows: `SnoreToast` text

See note on "Windows 10 Fall Creators Update" in Windows section.
_**Short answer:** update your `appID`._

### Windows and WSL2

If you don't see notifications within WSL2, you might have to change premission of exe vendor files (snoreToast).
[See issue for more info](https://github.com/mikaelbr/node-notifier/issues/353)

### 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)

There’s even more info [here](https://github.com/mikaelbr/node-notifier/issues/61#issuecomment-163560801)
<https://github.com/mikaelbr/node-notifier/issues/61#issuecomment-163560801>.

### macOS: Custom icon without Terminal icon

Even if you define an icon in the configuration object for `node-notifier`, you will
see a small Terminal icon in the notification (see the example at the top of this
document).

This is the way notifications on macOS work. They always show the icon of the
parent application initiating the notification. For `node-notifier`, `terminal-notifier`
is the initiator, and it has the Terminal icon defined as its icon.

To define your custom icon, you need to fork `terminal-notifier` and build your
custom version with your icon.

See [Issue #71 for more info](https://github.com/mikaelbr/node-notifier/issues/71)
<https://github.com/mikaelbr/node-notifier/issues/71>.

### 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.

You can do so with the following command:

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

### Using with pkg

For issues using with the pkg module. Check this issue out: https://github.com/mikaelbr/node-notifier/issues/220#issuecomment-425963752

### Using Webpack

When using `node-notifier` inside of `webpack`, you must add the snippet below to your `webpack.config.js`.

This is necessary because `node-notifier` loads the notifiers from a binary, so it
needs a relative file path. When webpack compiles the modules, it supresses file
directories, causing `node-notifier` to error on certain platforms.

To fix this, you can configure webpack to keep the relative file directories.
Do so by append the following code to your `webpack.config.js`:

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