Push Notification Architecture in React Native
The architecture of React Native push notifications involves three main components: the mobile app, a push notification service, and the backend server.
- Mobile App: This is where notifications are received and displayed. React Native apps must register with the platform’s notification service (FCM for Android, APNs for iOS) to receive push notifications.
- Push Notification Service: This could be Firebase Cloud Messaging (FCM) for Android or Apple Push Notification Service (APNs) for iOS. These services handle the delivery of notifications to the appropriate devices.
- Backend Server: The server sends the push notification request to the push notification service, along with the device’s token, payload (message content), and any other data needed to customize the notification.
This architecture ensures that push notifications on React Native are delivered reliably and efficiently across platforms.
Native Platform-Specific Notification Services (FCM/APNs)
When working with push notification in React Native, developers typically use Firebase Cloud Messaging (FCM) for Android and Apple Push Notification Service (APNs) for iOS. These are the two primary services for delivering notifications to users’ devices on each platform.
- FCM: For Android, FCM is the most widely used service. It provides an easy-to-use and scalable solution for sending notifications. FCM can handle notifications even when the app is in the background or terminated.
- APNs: For iOS, Apple Push Notification Service (APNs) is the native service that handles notification delivery. Unlike FCM, APNs requires additional configuration in Xcode to ensure it works correctly.
These services are critical when considering how to implement push notification in React Native, as they provide the foundation for sending notifications to users’ devices.
Expo Push Notifications and Other Cloud Services
Expo, a popular toolchain for building React Native apps, simplifies the process of setting up push notification in React Native. Expo abstracts away the complexities of dealing with FCM and APNs directly, offering an easier integration for developers, especially for those who may be new to React Native development.
Apart from Expo, cloud services like OneSignal and Pusher provide additional options for handling push notifications on React Native. These services offer advanced features such as targeted notifications, analytics, and even automated campaigns. If you’re looking for a simplified solution, Expo and other cloud services can be excellent alternatives for implementing push notifications.
Other React Native Libraries for Push Notifications
While Expo provides an excellent starting point for integrating notifications, there are other libraries available that offer more control and customization for React Native push notifications. Libraries like Notifee, React Native Firebase, and React Native Push Notification give developers advanced capabilities, such as:
- Notifee: Allows for customized notification appearances and features like media attachments, actions, and buttons.
- React Native Firebase: A robust library that enables integration with Firebase services, including push notifications, analytics, and more.
- React Native Push Notification: A flexible and lightweight solution for managing local and remote notifications in React Native apps.
Choosing the right library depends on your app’s requirements—whether you need simple notification handling or advanced customizations.
Demonstrating How to Set Up Push Notifications in React Native
Setting up push notifications in React Native can be broken down into several key steps:
- Install Required Packages: To start implementing push notifications on React Native, you need to install the relevant libraries (e.g., react-native-push-notification, @react-native-firebase/messaging).
- Configure Firebase or APNs: If you are using FCM for Android or APNs for iOS, you need to set up your project in the Firebase Console or Apple Developer portal. This includes generating the appropriate credentials (e.g., Firebase server key or APNs certificates).
- Obtain Push Notification Token: Each device must register for push notifications and receive a token. This token uniquely identifies the device, allowing you to send notifications to it.

Getting a Push Notification Token
In React Native push notifications, getting the push notification token is essential. This token is used to identify the specific device or app instance that should receive notifications. For example, using React Native Firebase, you can easily retrieve the device token by calling firebase.messaging().getToken().
Once the token is obtained, it should be securely stored in your backend server’s database for future use in sending push notification in React Native.
Sending a Test Notification
Before sending notifications to users, it’s crucial to test the integration. You can do this by sending a test notification from Firebase Console or using tools like Postman to simulate the backend’s request. This will allow you to ensure everything is working as expected and troubleshoot any potential issues early in the development process.
Storing a Push Notification Token in a Project
It’s important to store the device token securely in your backend to manage notifications properly. By associating the token with a user’s account or session, you can target specific users or groups for future notifications.
A typical implementation would involve sending the token to your server after the device registers for notifications, allowing you to manage it as part of your app’s user data.
Sending Notifications on the Server
Once you have stored the device’s token, you can use your backend to send push notifications to the device. This involves making a request to either FCM or APNs, including the token, payload (content of the notification), and any additional data. React Native push notifications will then be sent to the registered device, even if the app is not actively running.
Handling Received Notifications in React Native
Handling notifications is an essential part of how to implement push notification in React Native. When a notification is received, you need to decide how to display it to the user, especially if the app is running in the background or terminated.
You can manage how notifications are displayed and handled in the foreground, background, or when the app is closed. Libraries like Notifee and React Native Firebase offer hooks to manage these events effectively.
Sending Local Notifications with Expo
Expo simplifies the process of sending local notifications within your app. Unlike remote notifications that require server-side interaction, local notifications can be triggered based on user interactions within the app, such as setting reminders or alerts.
Using Expo’s Notifications API, you can schedule notifications locally without needing an external service.
Displaying Notifications with Notifee
For advanced push notifications on React Native, Notifee allows you to create highly customized notifications. This includes adding media, buttons, or custom sounds to notifications. With Notifee, you can deliver a richer notification experience that enhances user engagement.
Background Notifications
Handling background notifications is one of the most challenging aspects of push notification in React Native. Both Android and iOS have strict guidelines for background notifications. By using services like React Native Firebase, you can ensure notifications are delivered even when the app is not actively running, but additional configuration and testing are required to handle these scenarios appropriately.
Which Notifications Library Should You Use?
When choosing which library to use for push notification for React Native, consider the complexity of your app and your specific requirements. If you need simple integration, Expo is an excellent choice. However, for more control and customization, Notifee or React Native Firebase may be better options.
Troubleshooting Common Issues While Setting Up Push Notifications
Setting up React Native push notifications can be tricky, and developers often face issues like incorrect token handling, permission errors, or problems with notifications not appearing in the background. Common troubleshooting steps include checking the server’s configuration, verifying the device’s token, and ensuring the correct permissions are set in the app.
