# This Week In React #301: TanStack Start, React Aria, Base UI, Satori, Next.js, Vitest RSC, MobX

**[This Week In React](https://daily.dev/sources/twir)** · 9 min read · 2 upvotes · 0 comments

## Summary

TanStack Start reaches 1.0, a client-first full-stack React framework supporting both React and Solid, offering SPA-style routing with server rendering and typed server functions. Expo will now maintain React Native Web under the React Foundation, while Tamagui 3 and One 2.0 ship major rewrites. Deno is joining Cloudflare, with the standalone Deno runtime and Deno Deploy being sunset. JPEG XL lands in Chrome 155 and Firefox 158, Chrome 154 adds iframe content-sizing, and TypeScript is being ported to Rust in two separate efforts (Bun's typescript-go port and Theo's tsc-rs). Also covered: Next.js's upcoming critical security patch, React Aria 1.22's new Sheet component, Satori's switch to the Taffy layout engine, Base UI 1.9, Playwright 1.64, pnpm updates, and Partytown reaching 1.0 stability, plus a wide roundup of React Native ecosystem releases (Skia, RNTL, Screens, Nano Icons, Hot Updater, and more).

## Questions this post answers

### What does TanStack Start 1.0 offer compared to server-first React frameworks like Next.js?

TanStack Start 1.0 is a stable, client-first full-stack framework supporting both React and Solid, offering SPA-style routing, state, and caching combined with server rendering, streaming, and typed server functions. It provides end-to-end type safety across route params, search params, loader data, and server function inputs, deploys via Vite or Rsbuild with Nitro, and treats RSC as fully opt-in.

_Developers weighing client-first versus server-first React frameworks can track these tradeoffs on daily.dev._

### Is Deno being discontinued after joining Cloudflare?

Yes, the Deno runtime and Deno Deploy are being sunset after the Deno team joins Cloudflare. The team will instead work on Cloudflare Workers, aiming to make the Durable Objects programming model self-hostable, rather than continuing standalone Deno infrastructure.

_Teams relying on Deno Deploy can follow migration implications for their stack on daily.dev._

### When does JPEG XL support land in Chrome and Firefox?

JPEG XL support ships in Chrome 155 and Firefox 158, with Safari already offering partial support. This follows years of the format being absent from Chromium-based browsers, giving web developers broader cross-browser support for the high-efficiency image format.

_Developers planning image format adoption can watch browser rollout details like this on daily.dev._
