This simplifies the building of scalable and loosely coupled systems in event-driven architectures.

Firebase Cloud Messaging

What is Firebase Cloud Messaging?

Firebase Cloud Messaging (FCM) is a free cross-platform messaging service for sending and receiving messages and notifications across platforms like iOS, Android, and the web via cloud-based infrastructure. It supports both upstream and downstream messaging.
