Enhancing Forms with React Server Components
summary
Shows how React Server Components plus Next.js app router and React 19 features turn a plain message form into a low-JS, server-driven UX: uses server actions and the extended form component to post FormData directly to a Prisma-backed DB, enforces a max messages per user (demo uses 5 then tests at 8), and implements progressive enhancement so the form works with no JS. Adds client interactivity with a tiny automatic scroller, uses useActionState, useFormStatus to show pending/error states, and useOptimistic for instant updates that roll back on server rejection.
