   Faster FastAPI with simdjson and io_uring on Linux 5.19▲290

   A few months ago, I benchmarked FastAPI on an i9 MacBook Pro. I couldn't believe my eyes. A primary REST endpoint to `sum` two integers took 6 milliseconds to evaluate. It is okay if you are targeting a server in another city, but it should be less when your client and server apps are running on the same machine. FastAPI would have bottleneck-ed the inference of our lightweight UForm neural networks recently trending on HN under the title "Beating OpenAI CLIP with 100x less data and compute". (Thank you all for the kind words!) So I wrote another library. It has been a while since I have…

   Hyperdiv – Reactive, immediate-mode web UI framework for Python▲170

   Hello HN, I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to…

    Hstream – quick Python web apps – Streamlit alternative using htmx▲104

    I love Streamlit but have run into many situation where taking it from PoC to MVP state is insurmountable. With all the recent HN hype around htmx and sematic html / classless css I decided to build a Streamlit alternative using these on top of FastAPI. This has a couple advantages: 1) easier to extend when you move past PoC since the FastAPI app is exposed (allowing adding more routes) and hstream acts more like a typical web stack 2) with htmx and html (plus MVP.css) doing the heavy lifting the package is alot less complex and easier to reason about - and hopefully more performant…

I've previously posted about ymawky here: https://news.ycombinator.com/item?id=48080587 In the past month and a half, I've made some pretty major improvements: I've added CGI scripting support, so the server now supports query strings and dynamic content; and I've fully ported ymawky to run on Linux, rather than macOS-only. In addition to GET/PUT/HEAD/DELETE/OPTIONS requests, because of CGI support ymawky also accepts POST requests (only to CGI resources for now). I've also updated…
