Firebase services overview - Mini Project: Build & Apply

Firebase Services Overview

📖 Scenario: You are building a simple Firebase project to understand how different Firebase services work together. This project will help you set up basic Firebase services and see how they connect in a real app.

🎯 Goal: Create a Firebase project configuration with initial services setup including Authentication, Firestore database, and Cloud Storage. You will define the project data, add configuration variables, implement core service initialization, and finalize the Firebase app setup.

📋 What You'll Learn

Create a Firebase configuration dictionary with exact keys and values

Add a variable for Firebase project ID

Initialize Firebase services using the configuration

Complete the Firebase app initialization with all services connected

💡 Why This Matters

🌍 Real World

Firebase is widely used to build mobile and web apps with backend services like authentication, database, and storage without managing servers.

💼 Career

Understanding Firebase services setup is essential for roles in cloud development, mobile app development, and backend engineering using serverless platforms.

1

Create Firebase configuration dictionary

Create a dictionary called firebase_config with these exact entries: apiKey set to "AIzaSyA-1234567890abcdef", authDomain set to "myapp.firebaseapp.com", projectId set to "myapp-12345", storageBucket set to "myapp.appspot.com", messagingSenderId set to "1234567890", and appId set to "1:1234567890:web:abcdef123456".

# Your code here

Use a Python dictionary with the exact keys and string values as shown.

2

Add Firebase project ID variable

Create a variable called project_id and set it to the string "myapp-12345".

Firebase

firebase_config = {
    "apiKey": "AIzaSyA-1234567890abcdef",
    "authDomain": "myapp.firebaseapp.com",
    "projectId": "myapp-12345",
    "storageBucket": "myapp.appspot.com",
    "messagingSenderId": "1234567890",
    "appId": "1:1234567890:web:abcdef123456"
}
# Create the project_id variable with the exact string value
# Your code here

Need a hint?

Assign the exact string to the variable project_id.

3

Initialize Firebase services

Write code to initialize Firebase Authentication, Firestore, and Storage services using the firebase_config dictionary. Use variables named auth, db, and storage respectively.

Firebase

firebase_config = {
    "apiKey": "AIzaSyA-1234567890abcdef",
    "authDomain": "myapp.firebaseapp.com",
    "projectId": "myapp-12345",
    "storageBucket": "myapp.appspot.com",
    "messagingSenderId": "1234567890",
    "appId": "1:1234567890:web:abcdef123456"
}

project_id = "myapp-12345"
# Initialize auth, db, and storage variables using firebase_config
# Your code here

Need a hint?

Assign strings indicating initialization to auth, db, and storage variables to simulate service setup.

4

Complete Firebase app setup

Create a variable called firebase_app and set it to a dictionary containing the keys "config", "auth", "db", and "storage" with their corresponding variables firebase_config, auth, db, and storage as values.

Firebase

firebase_config = {
    "apiKey": "AIzaSyA-1234567890abcdef",
    "authDomain": "myapp.firebaseapp.com",
    "projectId": "myapp-12345",
    "storageBucket": "myapp.appspot.com",
    "messagingSenderId": "1234567890",
    "appId": "1:1234567890:web:abcdef123456"
}

project_id = "myapp-12345"

auth = "Authentication initialized with config"
db = "Firestore initialized with config"
storage = "Storage initialized with config"
# Create firebase_app dictionary with keys 'config', 'auth', 'db', 'storage'
# Your code here

Need a hint?

Combine all previous variables into one dictionary named firebase_app.
