Building Python Web APIs with FastAPI

By: Abdulazeez Abdulazeez Adeshina

Overview of this book

RESTful web services are commonly used to create APIs for web-based applications owing to their light weight and high scalability. This book will show you how FastAPI, a high-performance web framework for building RESTful APIs in Python, allows you to build robust web APIs that are simple and intuitive and makes it easy to build quickly with very little boilerplate code. This book will help you set up a FastAPI application in no time and show you how to use FastAPI to build a REST API that receives and responds to user requests. You’ll go on to learn how to handle routing and authentication while working with databases in a FastAPI application. The book walks you through the four key areas: building and using routes for create, read, update, and delete (CRUD) operations; connecting the application to SQL and NoSQL databases; securing the application built; and deploying your application locally or to a cloud environment. By the end of this book, you’ll have developed a solid understanding of the FastAPI framework and be able to build and deploy robust REST APIs.

Chapter 4: Templating in FastAPI

Now that we have learned how to handle responses from requests including errors in the previous chapter, we can proceed to render the responses from the request on a web page. In this chapter, we will learn how to render responses from our API to a web page using templates powered by Jinja, which is a templating language written in Python designed to help the rendering process of API responses.

Templating is the process of displaying the data gotten from the API in various formats. Templates act as a frontend component in web applications.

By the end of this chapter, you will be equipped with the knowledge of what templating is and how to use templates to render information from your API. In this chapter, we’ll be covering the following topics:

  • Understanding Jinja
  • Using Jinja2 templates in FastAPI
