Memory improvements in FastAPI 0.140.0 ⚡️ Around 50% less memory usage 🐬 The benchmark says 16x improvement, but that's an extreme case. It will depend on your app and usage of dependencies. Thanks to ipeluffo for the investigation! 🤓

It's wild that you can build and deploy an app with a proper backend ( @fastapi.tiangolo.com ), all from a chat. 🤯 Even on the web interface (ChatGPT Work). And it also helps you write better FastAPI code (even if not using @fastapicloud.com ). Amazing job by @patrick.wtf . 🙌

Are you using Codex / ChatGPT Work? Here's the official FastAPI Cloud extension. 🤩 Build, debug and deploy to FastAPI Cloud, right from your coding agent or chat. 😎 chatgpt.com/plugins/plug...

Typer 0.27.0 comes with improved help formatting for parameters, types, etc. ✨ Maybe a "breaking change" if you are testing for literal content 🤓 Part of something BIG @oxykodit.bsky.social is working on, coming soon 🍿 Building a CLI? I would use Typer 😎 github.com/fastapi/typer

GitHub - fastapi/typer: Typer, build great CLIs. Easy to code. Based on Python type hints.

FastAPI's router.frontend() now also supports router dependencies ✨ E.g. add cookie auth to a router, and a frontend at /admin. Handle the cookie auth in FastAPI, and let the frontend do its client-side routing (e.g. TanStack Router with React). In FastAPI 0.139.0 🔖

FastAPI, Typer, SQLModel, Asyncer All bundle their own Agent Library Skills ✨ Let your agents (Codex, Claude, Cursor, etc) help you write good code and avoid gotchas 🤓 New SQLModel and Asyncer just released with their own library skills 🔖 library-skills.io

library-skills now supports uv workspaces and npm/Bun workspaces. ✨ Auto-repair and sync of skills. Improved support for .claude (additional to .agents), it will ask you interactively what to use. Plus several other bug fixes and improvements. library-skills.io

I’ll keep doing everything I can to make building things easier. 🤓 This should make it much simpler to build full-stack apps with FastAPI, for you and your agents. ✨ Psst... teach your agent to use it with: uvx library-skills
