Firebase is a tool that gives you a full backend for your app quickly. It handles user login, a database, file storage, and more. But setting it up easily can hide tricky parts. The biggest risk is getting security rules wrong, which can expose your data.
This skill covers all the main Firebase services like Firestore, Cloud Functions, and Hosting. You will learn to design your data for how you search it, not how you think of it. The key lesson is to keep your data flat and duplicated instead of using traditional database joins.
In 2025, a common surprise is Firestore pricing. Reading data costs money, and a badly written listener can become very expensive. Plan your data model based on your query patterns to avoid big bills.
