Next.js 15 and React Server Components have completely changed the way we build and compile frontend applications.
Managing Server vs. Client Components
In the Next.js App Router (created by Vercel), components compile as Server Components by default. We discovered that keeping data-fetching logic on the server and passing raw props down to interactive client components yields smaller client-side bundles and faster page loading.
// Next.js dynamic client component import
import dynamic from 'next/dynamic';
const DynamicChart = dynamic(() => import('@/components/Chart'), {
ssr: false,
loading: () => <p className="text-muted">Loading chart analytics...</p>
});Resolving Hydration Conflicts
Hydration warnings occur when server-rendered HTML differs from the client-rendered bundle. We prevent these conflicts by wrapping browser-only calls (like local time conversion or client-side checks) in dedicated state variables that only trigger after mounting.
Frequently Asked Questions
Should we migrate existing Pages Router apps?
Only if the application is undergoing active development and requires the performance benefits of Server Components.
