Big news: the first-ever ✨ FastAPI Conf ✨ is coming! 📍 Amsterdam 📅 October 28 Meet the FastAPI team, connect with developers ☕️ 🎟️ Join the waitlist for early ticket access: fastapiconf.com

#Python Gems of the Day 💎 Otari (github.com/mozilla-ai/ota…): Mozilla AI’s open-source LLM Gateway written in Python. Can be self-hosted to provision custom budgets and API keys, and to track usage for OpenAI-compatible clients. It uses Any-LLM internally for routing the request to LLM APIs. Powered by @FastAPI Any-LLM (github.com/mozilla-ai/any…): Another @MozillaAI open-source project that provides a unified interface for interacting with multiple LLM APIs.

@adarshdigievo Nice! 🚀

With @FastAPI's new support for frontend you can now deploy full-stack apps to FastAPI Cloud 🏰 All in the same domain, no need to even worry about CORS 😎 fastapicloud.com/docs/builds-an…

FastAPI now has 100k GitHub stars ✨ 100k thank yous! 🙌 🍰 github.com/fastapi/fastapi

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

There's now an official @Redisinc SDK for FastAPI 🚀

FastAPI Cloud is now in Public Beta ⚡ Deploy @FastAPI apps with: fastapi deploy No waitlist. Try it now. 🚀 You Code. We Cloud. 😎 fastapicloud.com/blog/fastapi-c…

writing services with @FastAPI is a completely different experience. Code is really tiny, so much comes out of the box. It works like a charm but my mind is not able to adjust the fact that it is all cooked for me.

@exvillager It supports client-side routing, serving the index.html as a fallback.

@FastAPI how it's diff from normal static files serving?

FastAPI can now serve your frontend app ✨ With support for client-side routing 😎 Great for React with TanStack Router, Astro static builds, Vite-based apps, etc. 🎉 FastAPI version 0.138.0 🔖 fastapi.tiangolo.com/tutorial/front…

@GrunerMonzon StaticFiles didn't support client-side routing by default, as it's common in React and other frameworks.

@FastAPI it always could? I'm confused

@ReyArtAge Only with a static build output. But not in SSR mode as that requires executing Node.js in the backend.

@FastAPI I'm guessing next js is not supported since it was not mentioned?

@bugslife1919 Maybe with StaticFiles, losing client-side routing, or with some good amount of custom logic to get close to something like this, maybe with an additional external static file server like Nginx, handling separation of API and frontend by path in a termination proxy, or by domain.

@FastAPI How do we do it before?

@Mr_D_V_D You still build as normally, this is only for serving the already built frontend app, respecting client-site routing while also respecting your API path operations.

@FastAPI Main advantage of this approach than the normal build??

Teach your agent to use it with the embedded skill in FastAPI 🤖

@davidbrochart @ProjectJupyter 🤝

Thanks FastAPI for supporting @ProjectJupyter!

Here's FastAPI 0.137.2 🎁 Comes with a new utility mainly useful for extensions and advanced use cases that used to inspect app.routes (e.g. Jupyter's Jupyverse) 🤓 github.com/fastapi/fastapi

@davidbrochart What do you need them for? It would be great if you can create a GitHub Discussion with your user case.

@FastAPI Hmm what's the recommended way to get all the paths from a router now?

FastAPI 0.137.0: a big internal refactor for routers 🏗️ You are probably not affected, unless you are iterating on the internal router.routes, then check the docs 📝 If you use any third-party package that modifies FastAPI's internals and it stops working, let them know 🤓

Bug fix release 0.137.1 🐛
