Fetch Once, Render Everywhere: React Server Components in Expo Router
summary
Claims that React Server Components land in Expo Router to deliver server-rendered native views across iOS Android and web, using streaming server actions to send JSX-like JSON, dynamic UI cards, and interactive client chunks. Demos show a ChatGPT-style stream, movie cards with calendar and Spotify links, on-device contact and currency components, and even a generated tic‑tac‑toe — mostly working with occasional hiccups on a dev server. Implementation targets Expo SDK 51 and React 19 with an early beta planned this year.
