Reducing Main Thread Work in React Apps
Strategies for offloading heavy computations to Web Workers and optimizing hydration strategies in Next.js 14 to improve TTI (Time to Interactive).
A production-grade Next.js architecture demonstrating Server-Side Rendering, Dynamic Metadata, and Core Web Vitals optimization.
import { Suspense } from 'react'
import { Metrics, Hero } from '@/components'
// Server Component (RSC)
export default async function Page() {
const data = await fetchData() // Server-side fetch
return (
<main>
<Hero data={data} />
<Suspense fallback={<Skeleton />}>
<Metrics /> // Streaming UI
</Suspense>
</main>
)
}
Pre-rendered HTML on request time using getServerSideProps or App Router. Eliminates layout shift and boosts SEO rankings immediately.
Automatic image optimization with next/image, font subsetting, and route prefetching. Achieving < 100ms TBT (Total Blocking Time).
Dynamic Open Graph tags generated via generateMetadata. Structured JSON-LD data for rich search results.
Live metrics from the production deployment.
Content fetched server-side from CMS. Simulating /posts/[slug] dynamic routing with static generation.
Strategies for offloading heavy computations to Web Workers and optimizing hydration strategies in Next.js 14 to improve TTI (Time to Interactive).
