Long-awaited, Server-Sent Events in @fastapi.tiangolo.com ✨

This @fastapi.tiangolo.com feature has been cooking in my mind for 2 years or so. 😅

So happy it's finally out there. And I think the developer experience is just right (minimal and simple). ✨

FastAPI Extension - Visual Studio Marketplace Extension for Visual Studio Code - VS Code extension for FastAPI development

I've been working on something very cool for the past few months and today, it's finally yours!

The *official* @fastapi.tiangolo.com extension for VS Code has launched! 🎉

Install: marketplace.visualstudio.com/items?itemNa...
GitHub: github.com/fastapi/fast...

There's a @vscode.dev extension for @fastapi.tiangolo.com now! 🤯

It's so enjoyable to use, try it!

@savannah.dev did an amazing job with it. 🙌

@anthonypjshaw.bsky.social do you know who should I ask to get support for this in VS Code / GitHub Copilot?

Libraries should be able to provide their own official AI Agent Skills, in sync with new versions and features.

So I'm starting by shipping this in FastAPI. Next, Typer, SQLModel, etc. 🚀

Now it's time to ask your favorite coding agent to support it. 😎

Taking one (or several) for the (Python) team.

I promise we'll get back to Python. 🍰

Strict Content-Type Checking - FastAPI FastAPI framework, high performance, easy to learn, fast to code, ready for production

FastAPI 0.132.0 adds strict Content-Type checking for JSON requests 🏰

This would solve a CSRF risk in local-network apps (apps intended to run on users' machines, on localhost) 🔒️

If your clients don't send a Content-Type, you can also disable it: fastapi.tiangolo.com/advanced/str...

You get so many features from @fastapi.tiangolo.com when you declare a return type - response model...

And now you also get the best performance possible 😎🚀

I've been dreaming of this day since around one year ago when I started the LLM translations setup. ✨

Actually since the first translations years ago, LLMs made it actually feasible now.

I like when technology makes things easier and more accessible to all humans. 🌐

Exceptions and Errors - Typer Typer, build great CLIs. Easy to code. Based on Python type hints.

In Typer 0.23.0 (just released 🍫), when there are errors, by default it no longer shows local variables, but you can opt-in to enable it typer.tiangolo.com/tutorial/exc...

We'll drop support for typer-slim later, so make sure you depend on typer, not typer-slim.

typer-slim is now a shell package that only depends on typer. ⚰️

Thanks @oxykodit.bsky.social for the work on this 🙌

And thanks everyone that filled the Typer survey! 🙇

Typer Typer, build great CLIs. Easy to code. Based on Python type hints.

Typer 0.22.0 is out, dropping support for typer-slim, now it's all just typer, with Rich by default 🚀
