SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

React Server Components reduce client-side JavaScript and bundle cost by letting data fetching and rendering happen on the server for non-interactive UI.

Core Features & Use Cases

  • Server-first data fetching and rendering: Render UI on the server so the client receives less JavaScript.
  • Smaller bundles with clearer boundaries: Use Server Components as the default and add client-only interactivity via the use client directive.
  • Complement to SSR: Pair Server Components with server-side rendering so initial HTML can stay fast while interactivity is handled by Client Components.

Quick Start

Ask the AI to refactor a page so all data-fetching and non-interactive UI become Server Components by default, and only the parts that need state, effects, or event handlers are marked with 'use client'.

FAQPage Schema
How do I reduce client JavaScript bundle size in Next.js App Router?▼

Reduce client JavaScript bundle size by shifting data fetching and non-interactive rendering into React Server Components, marking only stateful or event-driven components with 'use client'.

What are React Server Components and how do they differ from SSR?▼

React Server Components are components that render on the server to ship less JavaScript, while SSR complements them by generating initial HTML fast and leaving interactivity to Client Components.

Can I use React Server Components for data mutations without a client-side fetch?▼

Yes, handle React Server Component mutations using server-side mechanisms like server functions or server actions, keeping the mutation logic entirely off the client.

When should I add the 'use client' directive in a React application?▼

Add the 'use client' directive only when a component requires interactivity such as state, effects, or event handlers, keeping all other UI as default Server Components.

What is the best way to structure a Next.js page to optimize bundle delivery?▼

The best way to optimize bundle delivery is refactoring pages so all data-fetching and static UI become async Server Components by default, isolating interactive surfaces with 'use client'.
