[](https://badge.fury.io/js/react-native-alarm-notification)
## Installing (React Native >= 0.60.0)
```sh
npm install react-native-alarm-notification --save
```
or
```sh
yarn add react-native-alarm-notification
```
If you are using react-native version 0.60 or higher you don't need to link [react-native-alarm-notification](https://github.com/emekalites/react-native-alarm-notification). The package is automatically linked when building the app. All you need to do after installing package is:
For iOS pod installation:
```bash
npx pod-install
```
or
```bash
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:
Show steps
**android/app/src/main/java/\/MainApplication.java**
- add `import com.emekalites.react.alarm.notification.ANPackage;` on the imports section
- add `packages.add(new ANPackage());` in `List getPackages()`;
**android/app/build.gradle**
add `implementation project(':react-native-alarm-notification')` in the `dependencies` block
**android/settings.gradle**
add:
```
include ':react-native-alarm-notification'
project(':react-native-alarm-notification').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-alarm-notification/android')
```
## Installing (React Native <= 0.59.x)
Expand
```sh
npm install react-native-alarm-notification --save
```
or
```sh
yarn add react-native-alarm-notification
```
Use `react-native link` to add the library to your project:
```sh
react-native link react-native-alarm-notification
```
## iOS manual Installation
Expand
**> In your `AppDelegate.h`**
Add at the top of the file:
```objective-c
#import
```
Then, add the 'UNUserNotificationCenterDelegate' to protocols:
```diff
- @interface AppDelegate : UIResponder
+ @interface AppDelegate : UIResponder
```
**> In your `AppDelegate.m`**
Add at the top of the file:
```objective-c
#import
#import
```
Then, add the following lines:
```objective-c
- (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:
```objective-c
@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.
```Info.plist
UIBackgroundModes
audio
```
## Android manual Installation

## Usage
```javascript
import ReactNativeAN from 'react-native-alarm-notification';
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 }
//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
```java
...
import android.content.Intent;
import android.os.Bundle;
import com.emekalites.react.alarm.notification.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
```js
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
```js
import ReactNativeAN from 'react-native-alarm-notification';
// 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](https://github.com/invertase/react-native-firebase)
