React Server Components: The Complete Architecture Guide

React Server Components have fundamentally changed how we think about React applications. This guide covers the architecture patterns that make RSC applications fast, scalable, and maintainable.

Server Component Patterns

// app/page.tsx - Server Component (default)
import { Suspense } from "react";
import { db } from "@/lib/database";

async function LatestPosts() {
  const posts = await db.post.findMany({
    take: 10,
    orderBy: { createdAt: "desc" },
    include: { author: true },
  });

  return (
    <div className="grid grid-cols-3 gap-6">
      {posts.map(post => (
        <PostCard key={post.id} post={post} />
      ))}
    </div>
  );
}

export default function HomePage() {
  return (
    <main>
      <h1>Latest Posts</h1>
      <Suspense fallback={<PostsSkeleton />}>
        <LatestPosts />
      </Suspense>
    </main>
  );
}
