firebase-js-sdk VS quickstart-android

Even though Firebase Auth is supposed to prevent duplicate emails automatically, I was still seeing duplicates. After digging through GitHub issues and Reddit discussions, I realized this problem has been around for a while.

**Add Firebase to Your Project**: If you haven’t done so already, you need to add Firebase to your project. You can follow the steps in this [link](https://firebase.google.com/docs/web/setup) to get started 🎉.

Surreal Database should have this built in, and I am hoping they will in the future just like Gel, Firebase and Supabase!

Google (2024) Firebase Studio AI [Software]. Available at: https://firebase.google.com (Accessed: 12 January 2025).

Firebase stands as an essential platform for crafting robust and scalable applications. Now, a significant advancement in the developer journey has arrived:

Firebase is an all-in-one platform that provides a suite of backend services, including a real-time, NoSQL JSON database. It's a powerhouse for building entire applications, especially mobile apps.

For backends, "Supabase or Firebase for setting up a backend with authentication and data storage."

Firebase - a Backend-as-a-service platform developed by Google to enable us to add authentication, database, real-time communication, file storage, cloud functions, and many others within software applications.

The core idea is to leverage the power of both cloud-based AI models and on-device (local) AI processing within a single application. The Firebase AI SDK provides this capability, allowing you to prioritize running AI tasks directly on the user's device whenever possible, while seamlessly falling back to cloud processing if the on-device model is unavailable or insufficient.

For years, the Firebase platform has been synonymous with rapid, scalable application development, largely built upon the foundations of its NoSQL databases, Firestore and the Realtime Database.
