Use Klein for the server and want to run it via Gunicorn.

from klein import Klein
app = Klein()

@app.route('/')
def hello(request):
    return "Hello, world!"

resource = app.resource

Working good in twistd -n web --class=twistdPlugin.resource but need add threads, how to do it?

Or how to start this with Gunicorn, now it's return me Application object must be callable.

    What are you trying to achieve? In many cases the only reason to use Gunicorn is to workaround the blocking nature single-threaded applications. When using Klein which uses Twisted under the hood, you don't need Gunicorn to handle multiple non-blocking calls. Is using Klein not enough for what you need? – pgpb.padilla Aug 14 '20 at 09:48
  • Looks like missing something, when i'm start Klein app with twistd + nginx(proxy) and got at least one GET request that takes (5-8 seconds) all else request get stuck.. Maybe you say what are wrong. In some GET request app do db connection and select that can take a few seconds, this block all else. So my point was, with Flask and Gunicorn same logic working nice as i can simple add a few threads or one more worker – Максим Дихтярь Aug 14 '20 at 15:20
