Exploring the Core Features

In the previous chapter, we found out how easy it is to install and start developing REST APIs using the FastAPI framework. Handling requests, cookies, and form data was fast, easy, and straightforward with FastAPI, as was building the different HTTP path operations.

To learn about the framework’s features further, this chapter will guide us on how to upgrade our REST APIs by adding some essential FastAPI features to the implementation. These include some handlers that can help minimize unchecked exceptions, JSON encoders that can directly manage endpoint responses, background jobs that can create audit trails and logs, and multiple threads to run some API methods asynchronously with the uvicorn’s main thread. Moreover, ...
