The Costs & Benefits of React Server Components
summary
React Server Components land as a third rendering environment on top of client and SSR, implemented in Next.js v13 beta, trading higher server CPU and complexity for lower client bundles and better throughput in very large apps. Live demo hits the Pokemon API and reveals React’s fetch default caching behavior (use cache: 'no-store' to force fresh data), and a client-converted case triggers an infinite fetch loop. Shopify’s Hydrogen tried then dropped RSC; benefits show up at scale, but nested client/server interleaving, routing and state edge cases increase implementation cost.
