The API is the brain of our system – it implements the business logic (how the data flows in and out of the system, but more importantly how it relates to the business requirements inside our system).
I believe that frameworks such as FastAPI are much easier to showcase through simple examples. So, in this chapter, we will go through some simple endpoints that are minimal self-contained REST APIs. We will use them to get acquainted with how this powerful framework handles requests and responses – the cardiovascular system of the web.
This chapter is meant to be a quick start introduction to the framework – here we will focus on standard REST API practices and how they are implemented in FastAPI. I will show how to send requests and modify them according to our needs, and I will explain how to retrieve all the data from...
