Demystifying React Server Components
summary
React Server Components give multiple server entry points instead of one global fetch, demonstrated with Next.js demos: a product page where a 4s recommendation query streams into the page using suspense so the top renders instantly, an infinite scroller that updates the URL and streams new server-rendered chunks, and an add‑to‑cart implemented as a use server action that works but needs Next.js revalidatePath to update the UI. Components are server by default, client interactivity requires use client, which creates bundled client boundaries; Next.js Waku and Expo already support RSC, React 9 stabilizes adoption.
