Handling asynchronous data operations

Asynchronous programming is a core feature of FastAPI that allows you to develop highly efficient web applications. It allows your application to handle multiple tasks concurrently, making it particularly well-suited for I/O-bound operations, such as database interactions, file handling, and network communication.

Let’s delve into leveraging asynchronous programming in FastAPI for data operations, enhancing the performance and responsiveness of your applications.

Getting ready

FastAPI is built on Starlette and Pydantic, which provide a robust foundation for writing asynchronous code in Python using the asyncio library with async/await syntax.

The asyncio library allows you to write non-blocking code that can pause its execution while waiting for I/O operations to complete, and then resume where it left off, all without blocking the main execution thread.

This recipe demonstrates the benefits of using asyncio with FastAPI in...
