Magento + React Server Components — Is It Ready in 2026?
React Server Components went stable in Next.js 14. For Magento, that means a product grid shipping zero client JavaScript and a PDP streaming from the server in under 200 ms. Two problems nobody has solved cleanly yet: cart state (per-session, stays client) and JWT refresh (cookie-bound, but Magento's token-refresh endpoint expects a client trigger). This post shows the real Next.js 14 code for a Magento RSC storefront, the boundary between server and client components, and a bundle-size comparison vs PWA Studio that explains why the rebuild is worth it on some projects and a waste on others.
