What are some examples of using FastAPI with async features?

Can you provide some examples of using FastAPI with async features?

Sure! FastAPI supports asynchronous programming, allowing you to handle requests concurrently. For example, you can use async functions with the async def syntax.

How do I create an async endpoint in FastAPI?

To create an async endpoint, you define a function with async def and use await for any asynchronous calls within it.

Can you show me a simple code snippet?

Absolutely! Here's a simple example:

from fastapi import FastAPI
import httpx

app = FastAPI()

@app.get("/async-example")
async def async_example():
    async with httpx.AsyncClient() as client:
        response = await client.get('https://api.example.com/data')
    return response.json()

What libraries can I use with FastAPI for async operations?

You can use libraries like httpx for HTTP requests, databases for async database access, and asyncio for concurrency.
