### How they appear to the user

Users see notifications in the following ways:

- Badging the app’s icon
- Progress indicator (OSX based on https://github.com/hokein/DockProgressBar)


### Supported Platforms

- __Android / Amazon FireOS__ (via [ShortcutBadger][shortcut_badger])
- __Browser__ (via [favico.js][favico_js])
- __iOS 10+__
- __OSX__
- __Windows__ (Phone and Desktop)


## Installation

The plugin can be installed via [Cordova-CLI][CLI] and is publicly available on [NPM][npm].

Execute from the projects root folder:

    $ cordova plugin add cordova-plugin-badge

Or install a specific version:

    $ cordova plugin add cordova-plugin-badge@VERSION

Or install the latest head version:

    $ cordova plugin add https://github.com/katzer/cordova-plugin-badge.git

Or install from local source:

    $ cordova plugin add <path> --nofetch --nosave


## Usage

The plugin creates the object `cordova.plugins.notification.badge` and is accessible after *deviceready* has been fired.

```js
document.addEventListener('deviceready', function () {
    // cordova.plugins.notification.badge is now available
}, false);
```

### Set the badge number

Badge numbers cannot be negative. The maximum might be restricted by the OS.
A callback is optional and will be invoked with the current badge number.

```js
cordova.plugins.notification.badge.set(10);
```

<p align="center">
    <img height="150px" src="images/ios.png">
    &nbsp;&nbsp;&nbsp;&nbsp;
    <img height="150px" src="images/android.png">
    &nbsp;&nbsp;&nbsp;&nbsp;
    <img height="150px" src="images/windows.png">
</p>

There's built-in support to increase the badge number:

```js
cordova.plugins.notification.badge.increase(1, function (badge) {
    // badge is now 11 (10 + 1)
});
```

To decrease the badge number:

```js
cordova.plugins.notification.badge.decrease(2, function (badge) {
    // badge is now 9 (11 - 2)
});
```

And to clear out the badge number:

```js
cordova.plugins.notification.badge.clear();
```

### Get the badge number

The default value is 0. The badge number wont get lost after reboot or app restart.

```js
cordova.plugins.notification.badge.get(function (badge) {
    ...
});
```

__Note:__ Modifying the badge number outside of the plugin does result into wrong behaivor!

### Configurations

To clear the badge number automatically if the user taps the app icon:

```js
cordova.plugins.notification.badge.configure({ autoClear: true });
```

OSX supports additional indicators. Other than to `badge` these are `circular` and `download`.

```js
cordova.plugins.notification.badge.configure({ indicator: 'circular' });
```

<p align="center">
    <img src="images/osx-badge.png">
    &nbsp;&nbsp;&nbsp;&nbsp;
    <img src="images/osx-circular.png">
    &nbsp;&nbsp;&nbsp;&nbsp;
    <img src="images/osx-download.png">
</p>


## Permissions

The plugin might ask for granting permissions to modify the badge number.
That's done automatically but it's also possible to request them manually:

```javascript
cordova.plugins.notification.badge.requestPermission(function (granted) {
    ...
});
```

<p align="center">
    <img height="200px" src="images/ios-permission.png">
</p>

To check if they have been granted already:

```javascript
cordova.plugins.notification.badge.hasPermission(function (granted) {
    ...
});
```


## Quirks

On Android not all launchers support badges. In order to set badges the plugin uses [ShortcutBadger][shortcut_badger]. Check out their website to see which launchers are supported.

If you're using PhoneGap Build please make sure you specify gradle as your Android build tool in config.xml:

```xml
<preference name="android-build-tool" value="gradle" />
```

To specify a custom version of _ShortcutBadger_ follow this [guide][gradle-guide]. The name of the property is `appShortcutBadgerVersion`.

```gradle
# In <your-project>/platforms/android/gradle.properties
appShortcutBadgerVersion=1.1.22
```
