Course Description

Learn how to build a RESTful API using Firebase Cloud Functions and Firestore in this free backend development course. You will go from initial project setup to a working API that handles common CRUD operations for a simple product resource.

Follow a practical workflow that starts with configuring Firebase, structuring a JavaScript web app, and creating routes that connect securely to Firestore. Along the way, you will implement endpoints to read a single item, fetch all items, and perform update and delete operations, reinforcing how REST patterns map to real serverless functions.

You will also see how to deploy your Cloud Functions and verify your API behavior using Postman, helping you gain confidence in testing and iterating on backend services. By the end, you will have a clear foundation for building scalable serverless APIs on Firebase, suitable for prototypes and production-ready applications alike.
