Have you used FastAPI in production or only in educational projects?

FastAPI is actively used in production due to its high performance and ease of development. It allows for quick creation of RESTful APIs with automatic documentation generation and support for asynchronous code. For example, in real projects, FastAPI is used for microservices where response speed and scalability are important.

Example of a simple FastAPI application:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def read_root():
    return {"message": "Hello, World!"}

This code can be easily deployed in production using Uvicorn or Gunicorn with asynchronous support.
