React Native Alarm

Installing (React Native >= 0.60.0)

npm install react-native-alarm-feature --save

or

yarn add react-native-alarm-feature

If you are using react-native version 0.60 or higher you don't need to link react-native-alarm-feature. The package is automatically linked when building the app. All you need to do after installing package is:

For iOS pod installation:

npx pod-install

or

cd ios && pod install

For android, the package will be linked automatically on build.

_ IMPORTANT _

If your app crashes on Android, it could probably mean auto linking didn't work. You will need to make the following changes:

android/app/src/main/java/<AppName>/MainApplication.java

• add import com.abhishek357.react.alarm.feature.ANPackage; on the imports section
• add packages.add(new ANPackage()); in List<ReactPackage> getPackages();

android/app/build.gradle

add implementation project(':react-native-alarm-feature') in the dependencies block

android/settings.gradle

add:

include ':react-native-alarm-feature'
project(':react-native-alarm-feature').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-alarm-feature/android')

Installing (React Native <= 0.59.x)

npm install react-native-alarm-feature --save

or

yarn add react-native-alarm-feature

Use react-native link to add the library to your project:

react-native link react-native-alarm-feature

iOS manual Installation

> In your AppDelegate.h

Add at the top of the file:

#import <UserNotifications/UNUserNotificationCenter.h>

Then, add the 'UNUserNotificationCenterDelegate' to protocols:

- @interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate>
+ @interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate>

> In your AppDelegate.m

Add at the top of the file:

#import <RnAlarmNotification.h>
#import <UserNotifications/UNUserNotificationCenter.h>

Then, add the following lines:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification withCompletionHandler: (void (^)(UNNotificationPresentationOptions options))completionHandler {
  [RnAlarmNotification didReceiveNotification:notification];
  completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}


- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)(void))completionHandler  API_AVAILABLE(ios(10.0)){
    [RnAlarmNotification didReceiveNotificationResponse:response];
    completionHandler();
}

And then in your AppDelegate implementation, add the following:

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  ...
  
  // Define UNUserNotificationCenter
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  center.delegate = self;
  
  return YES;
}

To play sound in the background, make sure to add the following to the Info.plist file.

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
</array>

Usage

import ReactNativeAN from 'react-native-alarm-feature';

const fireDate = ReactNativeAN.parseDate(new Date(Date.now() + 1000));     // set the fire date for 1 second from now
or
const fireDate = '01-01-2060 00:00:00';			  // set exact date time | Format: dd-MM-yyyy HH:mm:ss

const alarmNotifData = {
	title: "My Notification Title",
	message: "My Notification Message",
	channel: "my_channel_id",
	small_icon: "ic_launcher",

	// You can add any additional data that is important for the notification
	// It will be added to the PendingIntent along with the rest of the bundle.
	// e.g.
  	data: { foo: "bar" },
};

class App extends Component {
	...

    async method(){
        //Schedule Future Alarm
        const alarm = await ReactNativeAN.scheduleAlarm({ ...alarmNotifData, fire_date: fireDate });
        console.log(alarm); // { id: 1 }

        //Get Alarm details by alarm Id
        const alarm = await ReactNativeAN.getAlarm(AlarmId);
        console.log(alarm);    

        //Delete Scheduled Alarm
        ReactNativeAN.deleteAlarm(alarm.id);

        //Delete Repeating Alarm
        ReactNativeAN.deleteRepeatingAlarm(alarm.id);

        //Stop Alarm
        ReactNativeAN.stopAlarmSound();

        //Send Local Notification Now
        ReactNativeAN.sendNotification(alarmNotifData);

        //Get All Scheduled Alarms
        const alarms = await ReactNativeAN.getScheduledAlarms();

        //Clear Notification(s) From Notification Center/Tray
        ReactNativeAN.removeFiredNotification(alarm.id);
        ReactNativeAN.removeAllFiredNotifications();
    }

	...
}

Handle notification intent

...
import android.content.Intent;
import android.os.Bundle;

import com.abhishek357.react.alarm.feature.BundleJSONConverter;
import com.facebook.react.ReactActivity;
import com.facebook.react.modules.core.DeviceEventManagerModule;

import org.json.JSONObject;
...

public class MainActivity extends ReactActivity {
    ...

    @Override
    public void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        try {
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                JSONObject data = BundleJSONConverter.convertToJSON(bundle);
                getReactInstanceManager().getCurrentReactContext().getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class).emit("OnNotificationOpened", data.toString());
            }
        } catch (Exception e) {
            System.err.println("Exception when handling notification opened. " + e);
        }
    }

}

Listener for notifications

import { NativeEventEmitter, NativeModules } from 'react-native';

const { RNAlarmNotification } = NativeModules;
const RNAlarmEmitter = new NativeEventEmitter(RNAlarmNotification);

const dismissSubscription = RNAlarmEmitter.addListener(
    'OnNotificationDismissed', (data) => console.log(JSON.parse(e));
);

const openedSubscription = RNAlarmEmitter.addListener(
    'OnNotificationOpened', (data) => console.log(JSON.parse(e));
);

...

// unsubscribe, typically in componentWillUnmount
dismissSubscription.remove();
openedSubscription.remove();

iOS Permissions

import ReactNativeAN from 'react-native-alarm-feature';

// check if notification permissions has been granted for iOS
ReactNativeAN.checkPermissions((permissions) => {
	console.log(permissions);
});

// Request iOS permissions
ReactNativeAN.requestPermissions({
	alert: true,
	badge: true,
	sound: true,
}).then(
	(data) => {
		console.log('RnAlarmNotification.requestPermissions', data);
	},
	(data) => {
		console.log('RnAlarmNotification.requestPermissions failed', data);
	}
);

Some features are missing

This module is customized to help with scheduling and sending notifications (local) in react-native. A couple of helpful features may be missing but hopefully they can be added as time goes on.

NOTE: If you need a react-native module that takes care of Firebase Cloud Messaging, you could use react-native-firebase
