How can I improve the performance of my Flask app using async features?

You can enhance your Flask app's performance by using asynchronous programming with libraries like asyncio and aiohttp.

What are the benefits of using async in Flask?

Async allows your app to handle multiple requests concurrently, reducing response times and improving scalability.

Are there any specific libraries I should use?

Yes, consider using Flask-SocketIO for real-time communication and Quart, which is an async-compatible version of Flask.

Can you give me an example of async code in Flask?

Sure! Here's a simple example:

from flask import Flask
import asyncio

app = Flask(__name__)

@app.route('/async')
async def async_route():
    await asyncio.sleep(1)
    return 'This is an async response!'
