FastAPI Cookbook

Working with Data

Data handling is the backbone of any web application, and this chapter is dedicated to mastering this critical aspect. You will embark on a journey of working with data in FastAPI, where you’ll learn the intricacies of integrating, managing, and optimizing data storage using both Structured Query Language (SQL) and NoSQL databases. We’ll cover how FastAPI, combined with powerful database tools, can create efficient and scalable data management solutions.

Starting with SQL databases, you’ll get hands-on experience in setting up a database, implementing create, read, update and delete (CRUD) operations, and understanding the nuances of working with SQLAlchemy – a popular object-relational mapping (ORM) option for Python. We’ll then shift gears to NoSQL databases, delving into the world of MongoDB. You’ll learn how to integrate it with FastAPI, handle dynamic data structures, and leverage the flexibility and scalability of...

Technical requirements

To effectively run and understand the code in this chapter, ensure you have the following set up. If you’ve followed Chapter 1, First Steps with FastAPI, you should already have some of these installed:

  • Python: Make sure you’ve installed Python version 3.9 or higher on your computer.
  • FastAPI: Install FastAPI along with all its dependencies using the pip install fastapi[all] command. As we saw in Chapter 1, First Steps with FastAPI, this command also installs Uvicorn, an ASGI server that’s necessary to run your FastAPI application.
  • Integrated development environment (IDE): A suitable IDE such as VS Code or PyCharm should be installed. These IDEs offer excellent support for Python and FastAPI development, providing features such as syntax highlighting, code completion, and easy debugging.
  • MongoDB: For the NoSQL database portions of this chapter, MongoDB needs to be installed on your local machine. Download and install the...

Setting up SQL databases

In the world of data handling, the power of Python meets the efficiency of SQL databases. This recipe aims to introduce you to how to integrate SQL databases within your application, a crucial skill for any developer looking to build robust and scalable web applications.

SQL is the standard language for managing and manipulating relational databases. When combined with FastAPI, it unlocks a world of possibilities in data storage and retrieval.

FastAPI’s compatibility with SQL databases is facilitated through ORMs. The most popular one is SQLAlchemy. We will focus on it in this recipe.

Getting ready

To begin, you’ll need to have FastAPI and SQLAlchemy installed in your virtual environment. If you followed the steps in Chapter 1, First Steps with FastAPI, you should have FastAPI already set up. For SQLAlchemy, a simple pip command is all that’s needed:

$ pip install sqlalchemy

Once installed, the next step is to configure...

This book will help you leverage FastAPI’s immense potential to handle high-traffic scenarios and integrate seamlessly with modern Python tools. The book begins by familiarizing you with the basics of setting up and configuring your FastAPI environment before moving to the intricacies of building RESTful APIs, managing data with SQL and NoSQL databases, and handling authentication and authorization. Next, you'll focus on advanced topics such as custom middleware, WebSocket communication, and integration with various Python libraries. Each chapter is meticulously crafted with practical recipes, progressing from foundational concepts to advanced features and best practices. The concluding chapters show you how to optimize performance, implement rate limiting, and execute background tasks, empowering you to become a proficient FastAPI developer. By the end of this book, you'll have gained the skills you need to migrate existing apps to FastAPI, and be equipped to tackle any challenge in the modern web development landscape, ensuring your apps are not only functional, but also efficient, secure, and scalable.

Who is this book for?

This book is for Python developers looking to enhance their skills to build scalable, high-performance web apps using FastAPI.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
