How to Add Push Notifications to Your Next.js Mobile App
Implement push notifications in your Next.js mobile app using Capacitor's Push Notifications plugin and Firebase Cloud Messaging. Send notifications to iOS and Android users.
📋 Prerequisites
- Next.js app with Capacitor configured
- Firebase project created
- Apple Developer account (for iOS)
- Google Play Console access (for Android)
🎯 What You'll Learn
- Set up Firebase Cloud Messaging
- Configure iOS push notification certificates
- Configure Android push notifications
- Request notification permissions
- Handle incoming notifications
- Send test notifications
Step-by-Step Guide
Install Push Notifications Plugin
Install the Capacitor Push Notifications plugin in your project.
npm install @capacitor/push-notifications
npx cap sync
Set Up Firebase Project
Create a Firebase project if you haven't already, then add iOS and Android apps to your Firebase project. Download the configuration files.
💡 Note: Download google-services.json (Android) and GoogleService-Info.plist (iOS) from Firebase Console.
Configure iOS Push Notifications
Add the GoogleService-Info.plist to your Xcode project and enable Push Notifications capability.
1. Open your project in Xcode: npx cap open ios
2. Drag GoogleService-Info.plist into the App folder
3. Go to Signing & Capabilities
4. Click + Capability → Push Notifications
5. Add Background Modes → Remote notifications
💡 Note: You'll also need to create an APNs key in your Apple Developer account and upload it to Firebase.
Configure Android Push Notifications
Add the google-services.json file to your Android project.
# Copy google-services.json to android/app/
cp google-services.json android/app/
Request Notification Permissions
Create a hook or component to request notification permissions when your app launches.
import { useEffect } from 'react';
import { PushNotifications } from '@capacitor/push-notifications';
export function usePushNotifications() {
useEffect(() => {
// Request permission
PushNotifications.requestPermissions().then(result => {
if (result.receive === 'granted') {
// Register with Apple / Google
PushNotifications.register();
}
});
// Listen for registration
PushNotifications.addListener('registration', token => {
console.log('Push token:', token.value);
// Send token to your backend
});
// Listen for push notifications
PushNotifications.addListener('pushNotificationReceived', notification => {
console.log('Notification received:', notification);
});
// Handle notification tap
PushNotifications.addListener('pushNotificationActionPerformed', action => {
console.log('Notification action:', action);
});
}, []);
}
Use the Hook in Your App
Import and use the push notifications hook in your root layout or app component.
'use client';
import { usePushNotifications } from '@/hooks/usePushNotifications';
export default function RootLayout({ children }) {
usePushNotifications();
return (
<html>
<body>{children}</body>
</html>
);
}
Send a Test Notification
Use Firebase Console to send a test notification to your device.
1. Go to Firebase Console → Cloud Messaging
2. Click "Send your first message"
3. Enter notification title and text
4. Click "Send test message"
5. Paste your device token
6. Click "Test"
💡 Note: Your app must be running on a real device (not simulator) to receive push notifications.
Handle Notification Actions
Navigate users to specific screens when they tap notifications.
PushNotifications.addListener(
'pushNotificationActionPerformed',
(action) => {
const data = action.notification.data;
// Navigate based on notification data
if (data.screen === 'profile') {
router.push('/profile');
} else if (data.screen === 'post') {
router.push(`/posts/${data.postId}`);
}
}
);
