Firebase Cloud Messaging
Firebase Cloud Messaging (FCM) is a cross-platform messaging solution provided by Google that allows developers to send notifications and data messages to users on Android, iOS, and web applications. It handles message delivery, queuing, and routing, enabling reliable communication between servers and client apps. FCM is a key component of Firebase, Google's mobile and web app development platform.
Developers should use FCM when building mobile or web apps that require push notifications, such as for user engagement, real-time updates, or alerts. It is particularly useful for apps needing cross-platform messaging support, as it simplifies implementation with a single API for Android, iOS, and web. FCM is ideal for scenarios like chat apps, news feeds, or e-commerce notifications where timely delivery is critical.
