Using FastAPI in IT Projects

In the ever-evolving landscape of software development, choosing the right framework for your project can be a daunting task. FastAPI, a modern, fast, web framework for building APIs with Python, has been gaining traction for its performance, ease of use, and robust features.

What is FastAPI?

FastAPI is a Python-based web framework that is built on top of Starlette and Pydantic. It is designed to create RESTful APIs quickly and efficiently. One of the standout features of FastAPI is its automatic generation of OpenAPI and JSON Schema documentation, which makes it easier for developers to understand and use your API.

Why Choose FastAPI?


FastAPI is incredibly fast. It is built on Starlette for the web parts and Pydantic for the data parts, both of which are designed for speed. Benchmarks have shown that FastAPI applications can handle a larger number of requests per second compared to other frameworks, making it ideal for high-traffic IT projects.

Type Checking

FastAPI uses Python type hints in conjunction with Pydantic models to provide excellent support for type checking. This feature not only helps with data validation but also enables auto-completion, reducing the likelihood of errors.

Easy to Learn

FastAPI offers a gentle learning curve. If you are familiar with Python, you can get up and running with FastAPI in no time. The framework’s extensive documentation and community support further ease the learning process.


FastAPI is designed with scalability in mind. Whether you are building a small internal API or a large-scale public API, FastAPI has the tools and features to meet your needs.

Getting Started with FastAPI


Installing FastAPI is straightforward. You can install it using pip:

pip install fastapi

You’ll also need an ASGI server, such as Uvicorn:

pip install uvicorn

Basic Example

Here’s a simple example to create a FastAPI application:


from fastapi import FastAPI

app = FastAPI()

def read_root():
    return {"message": "Hello, World!"}

To run the application, use the following command:

uvicorn main:app --reload
