I've been working on a web search interface for #Python documentation as a personal project, and I think it's ready for other people to use...

Please give it a go (and join me in praying to the server gods):

Thanks to @PyMNtos for hosting my talk - "Build a simple web app with @htmx_org and @FastAPI"! The code and slides can be found here: https://t.co/mCcIVat9Ps and I'm planning to follow up with a blog post.

Tired of browsing #Python API docs online 😴 ?

Why not browsing them offline, directly in your terminal, thanks to #Griffe and #Textual 😎 ?

🚀 FastAPI Performance +265% 🚀🚀- 10 Tips from @marcelotryle maintainer of @FastAPI , Uvicorn, @pydantic and and #Starlette at @EuroPython:

1️⃣ use uvloop, performance +10%🚀, uvloop is a fast, drop-in replacement of the built-in asyncio event loop
2️⃣ use httptools - faster parsing +10%🚀, Python binding for nodejs HTTP parser, you just need to have it installed in your environment 
3️⃣ use bigger threadpool +5%🚀
4️⃣ use simple async application, +15%🚀, no overhead of threads
5️⃣ remove duplicate validation, have only FastAPI do the validation +25%🚀
6️⃣ use ORJSON + 5% 🚀(if not using the latest Pydanctic version already)
7️⃣ consider running without validation is an option, 150%, without logging +25%. Both not a general recommendation! 
8️⃣ use the most recent version of FastAPI, + 265% 🚀- this is related to pydantic going rust
9️⃣ use ASGI Middleware: see https://t.co/nAZuc0f42x
🔟 compress responses

@treyhunner Try to write dictionaries with key=value.

@garybernhardt I find this somewhat useful - but then again it's my project! https://t.co/3HIuiWDEHw

Posted about this on the Textual blog

Also posted it on HN, which I'm sure I'll regret.

@FastAPI will now use the function's return type to create docs and validate data against that Pydantic model.

At first, I was worried for a second, because sometimes I return dicts or Pydantic models that are different from the response_model.

Let me show some examples:

@treyhunner It's probably a bit too dynamic for real world use, but I thought this method of constructing a dataclass from local vars is pretty fun:

[Python Package Index @pypi]

Python 3.11 delivers.

[Dan O'Sullivan @dan_osull_com]

@browniepoints @davidfowl I did the same with my Surface Laptop. Noise-wise it's a little better but the main benefit is my laptop no longer thermal throttles.

@miguelgrinberg I use the asyncpg driver and actually have a blog post about it here: https://t.co/ZbGfIy90gW

[Simon Willison @simonw]

Just published the first (very much alpha) release of Datasette 1.0!

It previews the new authenticated JSON write API, which lets you create tables in your Datasette instance and insert/update/delete rows in them

[Architecture Notes @arcnotes]

Simon Willison (@simonw), the creator of Datasette, writes about SQLite and the challenges of building a server-side web application that also works in Electron and WebAssembly. It's a great read — I hope you enjoy it and hopefully learn something.
