@capacitor/push-notifications

The Push Notifications API provides access to native push notifications.

Install

``bash
npm install @capacitor/push-notifications
npx cap sync
`

iOS

On iOS you must enable the Push Notifications capability. See Setting Capabilities for instructions on how to enable the capability.

After enabling the Push Notifications capability, add the following to your app's AppDelegate.swift:

`swift
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
NotificationCenter.default.post(name: .capacitorDidRegisterForRemoteNotifications, object: deviceToken)
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error)
}
`

Android

The Push Notification API uses Firebase Cloud Messaging SDK for handling notifications. See Set up a Firebase Cloud Messaging client app on Android and follow the instructions for creating a Firebase project and registering your application. There is no need to add the Firebase SDK to your app or edit your app manifest - the Push Notifications provides that for you. All that is required is your Firebase project's google-services.json file added to the module (app-level) directory of your app.

$3

This plugin will use the following project variables (defined in your app's variables.gradle file):

- $firebaseMessagingVersion version of com.google.firebase:firebase-messaging (default: 23.0.5)

---

Push Notifications icon

On Android, the Push Notifications icon with the appropriate name should be added to the AndroidManifest.xml file:

`xml

`

If no icon is specified Android will use the application icon, but push icon should be white pixels on a transparent backdrop. As the application icon is not usually like that, it will show a white square or circle. So it's recommended to provide the separate icon for Push Notifications.

Android Studio has an icon generator you can use to create your Push Notifications icon.

Push notifications appearance in foreground

You can configure the way the push notifications are displayed when the app is in foreground.

| Prop | Type | Description | Since |
| ------------------------- | --------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- |
| presentationOptions | PresentationOption[] | This is an array of strings you can combine. Possible values in the array are: - badge: badge count on the app icon is updated (default value) - sound: the device will ring/vibrate when the push notification is received - alert: the push notification is displayed in a native dialog An empty array can be provided if none of the options are desired. badge is only available for iOS. | 1.0.0 |

$3

In capacitor.config.json:

`json
{
"plugins": {
"PushNotifications": {
"presentationOptions": ["badge", "sound", "alert"]
}
}
}
`

In capacitor.config.ts:

`ts
///

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
plugins: {
PushNotifications: {
presentationOptions: ["badge", "sound", "alert"],
},
},
};

export default config;
`





Silent Push Notifications / Data-only Notifications


#### iOS
This plugin does not support iOS Silent Push (Remote Notifications). We recommend using native code solutions for handling these types of notifications, see Pushing Background Updates to Your App.

#### Android
This plugin does support data-only notifications, but will NOT call pushNotificationReceived if the app has been killed. To handle this scenario, you will need to create a service that extends FirebaseMessagingService, see Handling FCM Messages.

Common Issues

On Android, there are various system and app states that can affect the delivery of push notifications:

* If the device has entered Doze mode, your application may have restricted capabilities. To increase the chance of your notification being received, consider using FCM high priority messages.
* There are differences in behavior between development and production. Try testing your app outside of being launched by Android Studio. Read more here.

Example

`typescript
import { PushNotifications } from '@capacitor/push-notifications';

const addListeners = async () => {
await PushNotifications.addListener('registration', token => {
console.info('Registration token: ', token.value);
});

await PushNotifications.addListener('registrationError', err => {
console.error('Registration error: ', err.error);
});

await PushNotifications.addListener('pushNotificationReceived', notification => {
console.log('Push notification received: ', notification);
});

await PushNotifications.addListener('pushNotificationActionPerformed', notification => {
console.log('Push notification action performed', notification.actionId, notification.inputValue);
});
}

const registerNotifications = async () => {
let permStatus = await PushNotifications.checkPermissions();

if (permStatus.receive === 'prompt') {
permStatus = await PushNotifications.requestPermissions();
}

if (permStatus.receive !== 'granted') {
throw new Error('User denied permissions!');
}

await PushNotifications.register();
}

const getDeliveredNotifications = async () => {
const notificationList = await PushNotifications.getDeliveredNotifications();
console.log('delivered notifications', notificationList);
}

`typescript
register() => Promise
`

Register the app to receive push notifications.

This method will trigger the 'registration' event with the push token or
'registrationError' if there was a problem. It does not prompt the user for
notification permissions, use requestPermissions() first.

Since: 1.0.0

--------------------




$3

`typescript
getDeliveredNotifications() => Promise
`

Get a list of notifications that are visible on the notifications screen.

Returns: Promise<DeliveredNotifications>

Since: 1.0.0

--------------------

`typescript
removeDeliveredNotifications(delivered: DeliveredNotifications) => Promise
`

Remove the specified notifications from the notifications screen.

| Param | Type |

`typescript
removeAllDeliveredNotifications() => Promise
`

Remove all the notifications from the notifications screen.
