Why production readiness matters in FastAPI - See It in Action

Why production readiness matters

📖 Scenario: You are building a simple web API using FastAPI to share motivational quotes. This API will be used by friends and family to get a daily quote. To make sure your API works well when many people use it, you need to prepare it for production.

🎯 Goal: Build a basic FastAPI app with a quotes list, add a configuration for maximum quotes to return, implement the logic to return only that many quotes, and complete the app with a proper startup message.

📋 What You'll Learn

Create a list of quotes with exactly 3 motivational quotes

Add a configuration variable called max_quotes set to 2

Write a function to return only max_quotes number of quotes

Add a startup event handler that prints 'App is ready for production!'

💡 Why This Matters

🌍 Real World

Preparing a FastAPI app for production ensures it runs reliably and efficiently when many users access it.

💼 Career

Understanding production readiness is key for backend developers to deploy stable and maintainable APIs.

1

Create the quotes list

Create a list called quotes with these exact strings: 'Keep going!', 'You can do it!', and 'Never give up!'

FastAPI

# Create the quotes list with 3 motivational quotes
# Your code here

Need a hint?

Use square brackets to create a list and separate the quotes with commas.

2

Add max_quotes configuration

Add a variable called max_quotes and set it to 2 to limit how many quotes to return

FastAPI

quotes = ['Keep going!', 'You can do it!', 'Never give up!']
# Add max_quotes variable set to 2
# Your code here

Need a hint?

Just create a simple variable with the number 2.

3

Write function to get limited quotes

Write a function called get_quotes that returns only the first max_quotes items from the quotes list

FastAPI

quotes = ['Keep going!', 'You can do it!', 'Never give up!']
max_quotes = 2

# Define get_quotes function to return limited quotes
# Your code here

Need a hint?

Use list slicing to get the first max_quotes items.

4

Complete FastAPI app with startup event

Import FastAPI, create an app instance called app, add a startup event handler that prints 'App is ready for production!', and add a GET route /quotes that returns the result of get_quotes()

FastAPI

quotes = ['Keep going!', 'You can do it!', 'Never give up!']
max_quotes = 2

def get_quotes():
    return quotes[:max_quotes]

# Import FastAPI and create app
# Add startup event handler
# Add GET /quotes route
# Your code here

Need a hint?

Use @app.on_event('startup') to add the startup message and @app.get('/quotes') for the route.
