If you are looking for a modern, easy-to-use and high-performance web framework for building APIs with Python, then FastAPI is the right choice for you. In this blog post, we will discuss how to get started with FastAPI and some of its key features.
Installation
The first step to get started with FastAPI is to install it. You can install FastAPI using pip:
pip install fastapi
Once it is installed, you can import it into your project:
from fastapi import FastAPI
Creating an App
The next step is to create an app with FastAPI. You can do this by creating an instance of the FastAPI class:
app = FastAPI()
Adding Routes
Once your app is created, you can start adding routes to it. Routes are used to map URLs to functions or classes that handle requests. To add a route, you can use the @app.get decorator:
@app.get("/")
def home():
return {"message": "Hello, world!"}
This route will map the URL / to the home() function which will return a JSON response with the message "Hello, world!".
Running the App
Once you have added all the routes, you can run the app by calling the run() method:
app.run()
This will start the development server and your app will be available at http://127.0.0.1:8000.
