Firebase Cloud Functions
Firebase Cloud Functions is a serverless compute platform that lets you run backend code in response to events triggered by Firebase features and HTTPS requests. It automatically scales with your app, handles infrastructure management, and integrates seamlessly with other Firebase services like Firestore, Authentication, and Realtime Database. This allows developers to build serverless applications without managing servers.
Developers should use Firebase Cloud Functions when building event-driven backends for Firebase-based apps, such as processing data after a Firestore write, sending notifications on user authentication, or creating REST APIs. It's ideal for mobile and web apps that need lightweight, scalable server-side logic without the overhead of server management, particularly in prototyping or small-to-medium projects.
