React-native-ibm-mobilefirst-push NPM

IBM MobileFirst - Push React Native SDK plug-in

To add IBM MobileFirst™ Push capabilities to an existing React Native app, you add the react-native-ibm-mobilefirst & react-native-ibm-mobilefirst-push plug-in to your app. The react-native-ibm-mobilefirst plug-in contains the IBM MobileFirst Platform Foundation SDK and the react-native-ibm-mobilefirst-push contains all the APIs to work with Push Notifications.

Refer to the documentation links for more information.

Installation

Download the react-native-ibm-mobilefirst-push.tar.gz from this repo and run the following command to install Push plugin

npm install react-native-ibm-mobilefirst-push --save

Getting Started

Pre-requisites

Make sure you have all the pre-requisites for a React Native app covered. See the React Native Getting Started page if you're new to this whole stuff.
Setup of MobileFirst server

Create React Native Project

The first step is to create a React Native project. Let's call our app as the MobileFirstApp. Use the React Native CLI to create a new project.

react-native init MFPPushApp

Next, add the react native plugin to your app

cd MFPPushApp
npm install react-native-ibm-mobilefirst-push —-save

Link your project so that all native dependencies are added to your React Native project. This step is not required for react-native version 0.60 and above.

react-native link

Install Mobilefirst specific cocopods dependencies to the project.

cd ios && pod install

This step is applicable only for iOS platform.

react-native-ibm-mobilefirst-push plugin internally depends on react-native-ibm-mobilefirst plugin, so your app will be required to have mfpclient configuration file. Make sure your application is added with mfpclient configuration file updated with Valid MobileFirst Server Host Address.
Setup the Push Notifications feature in MobileFirst Server Operations Console for Android and iOS Platforms. Refer this documentation for more details.

Configure the Application

Android

Add the following lines to AndroidManifest.xml ({project-folder}/android/app/src/main/) :

	- `xmlns:tools="http://schemas.android.com/tools"` ---  within the **manifest** tag
	- `tools:replace="android:allowBackup"` --- within the **application** tag

Register the application: mfpdev app register (NOTE: Double check the values in mfpclient.properties file)
Register your app on Firebase Console. - create a new Project - go to Project Settings - click on Add Firebase to your Android app - give the package name com.ibm.mobilefirstplatform.clientsdk.android.push - click on Register app and skip the rest of the steps - add another app by clicking add App button - give the package name just as you have in your app. For eg. com.myreactnativeapp - click on Register app - download the config file — google-services.json and paste it inside /<YOUR—REACT—NATIVE—APP>/android/app/ directory

Configure your app - open AndroidManifest.xml and add the following in the tag

		```
		<uses-permission android:name="android.permission.INTERNET" />
		<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
		<uses-permission android:name="android.permission.WAKE_LOCK"/>
		```
	in the **application** tag inside the Main Activity of the app add the following intent-filter:

		```
		<intent-filter>
	 	
		 	<action android:name="YOUR.PACKAGE_NAME.HERE.IBMPushNotification" />
		
			<category android:name="android.intent.category.DEFAULT" />
	
		</intent-filter>
		```
	also, add the following under the **application** tag:

		```
		<activity 
		 	android:name="com.ibm.mobilefirstplatform.clientsdk.android.push.api.MFPPushNotificationHandler" 
		 	android:theme="@android:style/Theme.NoDisplay"/>

		<!-- MFPPush Intent Service -->
		<service android:exported="true" android:name="com.ibm.mobilefirstplatform.clientsdk.android.push.api.MFPPushIntentService">
	  		<intent-filter>
		      	<action android:name="com.google.firebase.MESSAGING_EVENT" />
	      	</intent-filter>
		</service>
	
		<service android:name="com.ibm.mobilefirstplatform.clientsdk.android.push.api.MFPPush" android:exported="true">
		   	<intent-filter>
	      		<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
	      	</intent-filter>
		</service>
		```

open /MFPPushApp/android/build.gradle file - add the following line to dependencies{ … } inside the buildscript{ … } block
```
		`classpath 'com.google.gms:google-services:4.0.0'`
```

open /MFPPushApp/android/app/build.gradle file - add the following lines inside the dependencies{…}

		```
		implementation 'com.google.firebase:firebase-core:16.0.1'
		implementation 'com.google.android.gms:play-services-base:15.0.1'
		implementation 'com.google.firebase:firebase-messaging:17.1.0'
		```
	- finally add the following line at the end of the build.gradle file:

		 `apply plugin: 'com.google.gms.google-services'`

To run the application : react-native run-android

iOS

Make sure your iOS Application is configured with valid provisioning profile enabled with push capability

By default, React Native creates a native iOS project built with application delegate class, therefore you will need to add the following code below to application delegate(AppDelegate.m) class file.

	```
	- (void) application:(UIApplication *) application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
	  [[NSNotificationCenter defaultCenter] postNotificationName:@"RNMFPPushDidRegisterForRemoteNotificationsWithDeviceToken" object:deviceToken];
	}

	- (void) application:(UIApplication*)application didFailToRegisterForRemoteNotifications: (NSError*) error {
	  [[NSNotificationCenter defaultCenter] postNotificationName:@"RNMFPPushDidFailToRegisterForRemoteNotificationsWithError" object:error];
	}

	- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
	  [[NSNotificationCenter defaultCenter] postNotificationName:@"RNMFPPushDidReceiveRemoteNotification" object:userInfo];
	}
	```

To run the application : react-native run-ios

Note : In XCode, in the project navigator, drag and drop mfpclient.plist from ios folder. This step is applicable only for iOS platform.

React Native App

We need to add a Notification Event Listener in order to be notified when a Push Notification arrives. For this, add the following code to your JS file.

Register a Notification Callback by using the registerNotificationsCallback API of MFPPush class: MFPPush.registerNotificationsCallback("my_listener");

	Finally add the following code to define a Event Listener:
	
	```
	import {Platform, DeviceEventEmitter, NativeAppEventEmitter} from 'react-native';
	import {MFPPush, MFPSimplePushNotification} from 'react-native-ibm-mobilefirst-push'

	const emitter = Platform.select({
	  	ios: NativeAppEventEmitter,
	  	android: DeviceEventEmitter,
	});

	emitter.addListener("my_listener", function(notification) {
		// Here 'notification' is an instance of MFPSimplePushNotification class
	  	console.log(notification.getAlert());
	});

	```
