Hey devs,

Big news this week... the TanStack ecosystem just got bigger!

TanStack AI was just released.

It's a powerful, open-source AI SDK with a unified interface across multiple providers.

Here's the gist of it:

• Framework agnostic: Usable with React, Solid, vanilla JavaScript

• Provider agnostic: Supports OpenAI, Anthropic, Gemini, and Ollama

• Type-safe: With a top-notch DX

• Isomorphic: Define environment-aware tools

• DevTools: Already supported by TanStack Devtools

Critical Security Vulnerability in React Server Components

There is an unauthenticated remote code execution vulnerability in React Server Components.

If you use NextJS or React Router, upgrade to the patched versions following the official guide:

https://react.dev/blog/2025/12/03/critical-security-vulnerability-in-react-server-components#update-instructions

But if you're on TanStack Start, you're good to go ;)

TypeScript != Type-Safe

...is one of the things that Tanner Linsley shares in his latest talk at React Summit.

Covered topics include Client-first architecture, isomorphic code execution, and more.

Prisma Hackathon

Only two days left to submit your project to Prisma's official Hackathon.

If you already built a full stack app with TanStack Start and Prisma, then you can simply submit it.

They have cool prizes, check it out here: https://hackathon.prisma.io/

Another Package In The Works

A new TanStack package is coming soon: Headless chatbot UI components.

From the latest blog post:

Think Radix, but for AI chat interfaces. Fully functional, completely unstyled components for React and Solid that you can skin to match your application.

Christmas came early!
