Web App Architecture with Firebase (Beginner to Pro)

This document explains the architecture of the web app we've built, which is a modern architecture known as "Serverless" or Backend-as-a-Service (BaaS), primarily using tools from Google's Firebase.

Level 1: The Big Picture for Beginners

To make it easy to understand, let's imagine our application is a "coffee shop":
