Firebase Cloud Messaging in Node.js: Send Push Notifications to a Single Device
In this tutorial, we’ll walk through how to set up push notifications in a Node.js (Express) server using the Firebase Admin SDK. You’ll learn how to store a single FCM device token, then send a notification to that specific token. We’ll also use Postman for testing, and showcase how this can be integrated into a Flutter app. By the end, you’ll have a clear understanding of how to send targeted, real-time notifications from your backend to any device.
Key Takeaways
Initialize Firebase Admin with a service account.
Store a single device token (in-memory for demo).
Send a notification with a custom title and body.
Test using Postman and integrate with your Flutter frontend.
