Client-server architecture in Rest API - Mini Project: Build & Apply

Client-server architecture

📖 Scenario: You are building a simple client-server system where the server holds data about books and the client requests this data.This is like a library where the librarian (server) has a list of books, and the visitor (client) asks for information about the books.

🎯 Goal: Create a basic server that stores book data and a client that requests and displays this data.

📋 What You'll Learn

Create a server with a dictionary of books and their authors

Add a configuration variable for the API endpoint

Write a function to get book data from the server

Print the book data received by the client

💡 Why This Matters

🌍 Real World

Client-server architecture is the foundation of many web and mobile applications where clients request data and servers respond.

💼 Career

Understanding client-server basics is essential for roles like backend developer, frontend developer, and full-stack engineer.

1

DATA SETUP: Create the server data

Create a dictionary called books with these exact entries: '1984': 'George Orwell', 'To Kill a Mockingbird': 'Harper Lee', 'The Great Gatsby': 'F. Scott Fitzgerald'

Rest API

# Create the books dictionary with exact entries
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact book titles as keys and authors as values.

2

CONFIGURATION: Define the API endpoint

Create a variable called api_endpoint and set it to the string '/get_books'

Rest API

books = {
    '1984': 'George Orwell',
    'To Kill a Mockingbird': 'Harper Lee',
    'The Great Gatsby': 'F. Scott Fitzgerald'
}
# Define the API endpoint string
# Your code here

Need a hint?

Set api_endpoint exactly to the string '/get_books'.

3

CORE LOGIC: Write a function to get books from the server

Define a function called get_books that takes no parameters and returns the books dictionary

Rest API

books = {
    '1984': 'George Orwell',
    'To Kill a Mockingbird': 'Harper Lee',
    'The Great Gatsby': 'F. Scott Fitzgerald'
}

api_endpoint = '/get_books'

# Define the get_books function
# Your code here

Need a hint?

Write a function named get_books that returns the books dictionary.

4

OUTPUT: Print the books data from the client

Call the get_books() function and print the returned dictionary

Rest API

books = {
    '1984': 'George Orwell',
    'To Kill a Mockingbird': 'Harper Lee',
    'The Great Gatsby': 'F. Scott Fitzgerald'
}

api_endpoint = '/get_books'

def get_books():
    return books

# Print the books data from the client
# Your code here

Need a hint?

Use print(get_books()) to show the books dictionary.
