Introduction
Introduction to OneSignal as a powerful and user-friendly solution for implementing push notifications.
Step 1: Install OneSignal React Native SDK & Link
Install the OneSignal React Native SDK by running the following command in your project directory.
npm install react-native-onesignal
npx react-native link react-native-onesignalStep 2: Set Up OneSignal Account
- Go to the OneSignal website and create an account if you don’t have one.
- After logging in, create a new app and follow the instructions to set up your app on OneSignal.
Step 3: Configure OneSignal in Your App
Add it below codes in your root file.
import OneSignal from 'react-native-onesignal';
OneSignal.setAppId('<---APP_ID--->');
//Method for handling notifications received while app in foreground
OneSignal.setNotificationWillShowInForegroundHandler(
notificationReceivedEvent => {
let notification = notificationReceivedEvent.getNotification();
const data = notification.additionalData;
// Complete with null means don't show a notification.
notificationReceivedEvent.complete(notification);
},
);
OneSignal.setNotificationOpenedHandler(notification => {
console.log('OneSignal: notification opened:', notification);
});Step 4: Test Push Notifications
Send a test notification from the OneSignal dashboard to verify that push notifications are working in your app.
Additional Setup for iOS
Step 1: Add OneSignal to CocoaPods
Open the ios/Podfile and add the following lines:
target 'YourAppName' do
# other pods...
pod 'OneSignal', '>= 3.0.0', '< 4.0.0' // Add this line
end
Save the Podfile and run the following commands in the ios directory:
pod installStep 2: Configure Info.plist
Open the ios/YourAppName/Info.plist file and add the following XML code:
<key>OneSignalAppId</key>
<string>YOUR_ONESIGNAL_APP_ID</string> // Replace YOUR_ONESIGNAL_APP_ID with OneSignal App ID.
Step 3: Code Modification
- Open your
AppDelegate.mfile located inios/YourAppName/AppDelegate.m. - Add the following import statement at the top:
#import <OneSignal/OneSignal.h>Add the following method to initialize OneSignal in the didFinishLaunchingWithOptions method:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// other code...
[OneSignal initWithLaunchOptions:launchOptions
appId:@"YOUR_ONESIGNAL_APP_ID"
handleNotificationReceived:^(OSNotification *notification) {
// Handle received notification
}
handleNotificationAction:^(OSNotificationOpenedResult *result) {
// Handle notification opened
}
settings:@{kOSSettingsKeyInAppAlerts: @NO, kOSSettingsKeyAutoPrompt: @YES}];
// other code...
}Step 4: Test on iOS Simulator or Device
Run your React Native app on an iOS simulator or device using the following command:
npx react-native run-ios
