Yo. Two points here.

* You can absolutely stay within structured concurrency constraints using ASGI.

* The ASGI spec doesn’t have anything to do with asyncio. It’s purely an async/await interface - You can build against it just fine using other concurrency backends.

That's really lovely, thanks for sharing.

Good call, given that it's not enabled in modern browsers, and is unreliably supported in proxies and servers.

It's for the best that it becomes widely treated as a non-feature of HTTP/1.1.

There's a pretty good reason there's a lot of folks building new frameworks for Python in this space right now: async.

Unlike WSGI frameworks we're now able to support WebSockets, lightweight backgrounds tasks, super-high-throughput performance, and all sorts of other goodies, that Flask, Django et al. aren't necessarily able to excel in.

Good news is that it's pretty likely that some of this may eventually feedback into Django, Flask, and others, but in the meantime it's a case of trying to bring the Python async ecosystem up to feature-parity with existing thread-concurrency frameworks as quickly as we possibly can.

Python is a hugely productive language. That's the benefit.

We're building out an async ecosystem here that makes it way more performance-competitive with Node and Go.

For a lot of folks it's going to hit a sweet spot of developer productivity plus ability to scale up hugely. That's a big deal.

Doesn't mean you have to use it, but there's no need to neg on the great work folks are doing in this space just because Python's not your preferred language of choice.

Just wanted to second @tiangolo's "Thanks for paving the way with Hug" - Absolutely yup! It's a lovely bit of interface design - definitely had a really positive impact on the space.

Authorship is always both an individual and a collective act of creativity. We've millenia of shared culture poured into us. Similarly the interplay between the feminine and the masculine voice: Each can only exists in contrast to the other, and we all have elements of both voices within.

There are 3 ASGI servers right now. Daphne, Uvicorn, Hypercorn.

For production deployments you’ll either want to run them with a supervisor process like supervisors/circus/etc. Or use gunicorn (uvicorn includes a gunicorn worker class).
