Server Components Pattern

Server Components in Next.js 16 fetch data server-side by default, pre-rendering content for better SEO and smaller client bundles. Move data fetching to server components instead of client-side logic to keep API keys secure and streamline rendering.

Server Components are the default in Next.js 16 and fetch data directly within components without client hydration overhead. This Server-First pattern eliminates the need for separate API routes for simple data fetching, reducing complexity compared to traditional SSR setups.

Keep API keys and credentials server-side by fetching data directly in server components or dedicated server endpoints (*.server.ts). Next.js 16 ensures secrets never reach the client bundle, improving security while simplifying data access for pages and layouts.

Yes. Server Components support Suspense streaming in Next.js 16, allowing you to stream pre-rendered content to the browser progressively. This improves perceived performance and enables graceful loading states for data-fetching pages and layouts.

Yes. Strict separation of client and server code is required to keep secrets on the server and avoid shipping server-side logic to the browser. Use 'use client' directives to mark interactive components, leaving the rest as server components by default.

Use Server Components when rendering data-heavy pages, layouts, or widgets where SEO, performance, and security matter. Avoid client-side fetching for authenticated data or sensitive operations; server components handle these safely without exposing credentials.
