How can I handle asynchronous requests in Flask-RESTful?

How can I handle asynchronous requests in Flask-RESTful?

You can use the async and await keywords in your Flask-RESTful routes to handle asynchronous requests.

Can you provide a code example?

Sure! Here's a simple example:

from flask import Flask
from flask_restful import Resource, Api
import asyncio

app = Flask(__name__)
api = Api(app)

class AsyncResource(Resource):
    async def get(self):
        await asyncio.sleep(1)  # Simulate a long-running task
        return {'message': 'This is an async response!'}

api.add_resource(AsyncResource, '/async')

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

What libraries do I need to install for this?

You'll need Flask and Flask-RESTful. You can install them using pip:

pip install Flask Flask-RESTful

Are there any performance considerations I should be aware of?

Yes, using async can improve performance for I/O-bound tasks, but it may add complexity. Make sure to test your application.
