User properties in Firebase - Mini Project: Build & Apply

Firebase User Properties Setup

📖 Scenario: You are building a mobile app that tracks user behavior. To personalize the experience, you want to set user properties in Firebase Analytics. These properties help you understand your users better and tailor content accordingly.

🎯 Goal: Set up Firebase user properties correctly to identify user preferences and demographics.

📋 What You'll Learn

Create a dictionary called user_properties with specific user property keys and values.

Add a configuration variable called max_properties to limit the number of properties.

Write a function called set_user_properties that applies the user properties to Firebase Analytics.

Complete the Firebase configuration by calling the function with the user properties.

💡 Why This Matters

🌍 Real World

Setting user properties in Firebase Analytics helps personalize app experiences and analyze user segments effectively.

💼 Career

Understanding how to configure and manage user properties is essential for roles in mobile app development, analytics, and cloud infrastructure management.

1

Create the user properties dictionary

Create a dictionary called user_properties with these exact entries: 'favorite_color': 'blue', 'subscription_level': 'premium', and 'age_group': '25-34'.

Firebase

# Your code here

Need a hint?

Use a Python dictionary with the exact keys and values given.

2

Add a configuration variable for max properties

Add an integer variable called max_properties and set it to 25 to limit the number of user properties.

Firebase

user_properties = {
    'favorite_color': 'blue',
    'subscription_level': 'premium',
    'age_group': '25-34'
}
# Your code here

Need a hint?

Just create a variable named max_properties and assign it the value 25.

3

Write the function to set user properties

Write a function called set_user_properties that takes a dictionary properties and sets each key-value pair as a user property using firebase.analytics().setUserProperties({key: value}). Use a for loop with variables key and value to iterate over properties.items(). Limit the number of properties set to max_properties.

Firebase

user_properties = {
    'favorite_color': 'blue',
    'subscription_level': 'premium',
    'age_group': '25-34'
}
max_properties = 25

# Your code here

Need a hint?

Use a loop to set each user property and stop when you reach max_properties.

4

Call the function to apply user properties

Call the function set_user_properties with the user_properties dictionary to apply the user properties in Firebase Analytics.

Firebase

user_properties = {
    'favorite_color': 'blue',
    'subscription_level': 'premium',
    'age_group': '25-34'
}
max_properties = 25

def set_user_properties(properties):
    count = 0
    for key, value in properties.items():
        if count >= max_properties:
            break
        firebase.analytics().setUserProperties({key: value})
        count += 1

# Your code here

Need a hint?

Just call set_user_properties with user_properties as the argument.
