FastAPI Tutorial – Getting Started Made Easy

If you are looking to get started with FastAPI, you’ve come to the right place. FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+. It’s easy to use, easy to learn, and it comes with great features that can help you build powerful and efficient APIs.

Why Choose FastAPI?

FastAPI is built on top of standard Python type hints and is designed to be easy to use, while also being highly efficient and fast. With FastAPI, you can build APIs with automatic interactive documentation using OpenAPI and JSON Schema and it also has built-in support for automatic data validation, serialization, and deserialization.

Getting Started with FastAPI

To get started with FastAPI, you will need to have Python 3.7+ installed on your system. Once you have Python installed, you can use pip to install FastAPI and Uvicorn, which is the ASGI server that FastAPI uses.


$ pip install fastapi
$ pip install uvicorn


Once you have FastAPI and Uvicorn installed, you can create a new Python file and start building your first FastAPI application.

Example FastAPI Application

“`python
from fastapi import FastAPI

app = FastAPI()

@app.get(“/”)
async def root():
return {“message”: “Hello, World”}
“`

In this example, we have created a simple FastAPI application with a single endpoint that returns a JSON response with a hello message. You can run this application using the Uvicorn ASGI server and access it through your web browser or a tool like curl.


$ uvicorn yourfilename:app --reload
