Can you provide examples of using Flask with asyncio extensions?

Sure! Flask can be extended with asyncio to handle asynchronous requests. One example is using the Quart framework, which is a Flask-compatible framework that supports asyncio.

How do I set up Quart for my project?

To set up Quart, you can install it via pip: pip install quart. Then, you can create a simple app like this:

from quart import Quart

app = Quart(__name__)

@app.route('/')
async def hello():
    return 'Hello, Async World!'

if __name__ == '__main__':
    app.run()

What are the benefits of using asyncio with Flask?

Using asyncio with Flask allows for handling multiple requests concurrently, improving performance for I/O-bound tasks, such as database queries or API calls.

Can you show me a more complex example?

Absolutely! Here's a more complex example that uses asyncio with a database call:

from quart import Quart, jsonify
import asyncio

app = Quart(__name__)

async def fetch_data():
    await asyncio.sleep(1)  # Simulate a database call
    return {'data': 'Sample Data'}

@app.route('/data')
async def get_data():
    data = await fetch_data()
    return jsonify(data)

if __name__ == '__main__':
    app.run()
