Creating a Basic Web App with FastAPI

Creating a basic web app with FastAPI is simple and straightforward. All you need to do is create a new file and write the following code:

from fastapi import FastAPI

app = FastAPI()

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

@app.get("/user/{user_id}")
def get_user(user_id: int):
    return {"user_id": user_id}

This endpoint will respond to requests sent to the /user/{user_id} route with a JSON object containing the user_id parameter.
