Re: Using a background thread with asyncio/futures with flask

Hey, As far as I know (might be old news) flask does not support asyncio. You would have to use a different framework, like e.g. FastAPI or similar. Maybe someone has already written "flask with asyncio" but I don't know about that. Cheers Lars Lars Liedtke Lead Developer [Tel.] +49 721 9
