Building amazing mobile apps has become a lot easier thanks to modern UI frameworks like SwiftUI and Jetpack Compose.

But sometimes, you need to run some code on the server

* to orchestrate API calls
* to write business logic once, and use from all your mobile clients
* for long running process that you don’t want to run on the client

However, setting up your own server sounds like a lot of work, and like a maintenance nightmare.

Cloud Functions for Firebase to the rescue! Cloud Functions allow you to build a serverless backend. They automatically scale to your application’s needs, and you can call them from your mobile app, and in response to events in other Firebase services, such as when a new user is created (or deleted), or a document was written to Cloud Firestore, and much more!

In this talk, you will learn what Cloud Functions are, what the benefits of using them are, the step-by-step of calling these functions from other Firebase products and how to use them in your Android and iOS apps.
