●Expertise Level

Production experience since Next.js 9 (2019), migrated multiple codebases through Pages Router to App Router. Deep understanding of React 18 concurrent features, RSC streaming, and the compile-time optimizations in Next.js 14/15. Built systems handling 10M+ monthly page views with perfect Lighthouse scores.

●When to Use React & Next.js

Building SEO-critical marketing sites that need server-side rendering and static generation for optimal Core Web Vitals scores

Developing complex SPAs with nested layouts, parallel routes, and intercepting routes (Next.js 14+ App Router patterns)

Creating hybrid applications that mix static pages (blog, docs) with dynamic authenticated sections (dashboard, admin)

Projects requiring incremental static regeneration (ISR) for content that updates hourly/daily without full rebuilds

Applications needing edge runtime deployment for sub-50ms TTFB globally via Vercel Edge or Cloudflare Pages

Teams wanting a unified full-stack framework with API routes, middleware, and server actions in one codebase

Building design systems where React Server Components reduce client bundle size by 40-60% vs traditional SPAs

●Best Practices

Structure components as Server Components by default; only add 'use client' when you need hooks, event handlers, or browser APIs

Use generateStaticParams for dynamic routes that can be pre-rendered at build time—reduces server load and improves TTFB

Implement parallel data fetching with Promise.all or parallel route segments instead of waterfall requests

Leverage server actions for mutations—they provide built-in CSRF protection and eliminate the need for separate API routes

Use next/dynamic with { ssr: false } for heavy client-only libraries (charts, rich text editors) to keep initial bundle lean

Configure next.config.js with strict image domains, security headers, and bundle analyzer for production audits

Implement error.tsx and loading.tsx at each route segment for granular error boundaries and loading states

●Common Pitfalls to Avoid

Mixing 'use client' and server components incorrectly—putting client boundaries too high in the tree negates RSC benefits entirely

Using useEffect for data fetching in App Router when server components or the fetch API with caching would be more efficient

Forgetting that Next.js 14+ fetch requests are cached by default—add { cache: 'no-store' } or revalidate options explicitly

Over-relying on useState/useReducer for server state—React Query or SWR handle cache invalidation, optimistic updates, and background refetching

Not understanding the streaming/suspense model—wrapping dynamic content in Suspense boundaries prevents blocking the entire page

Deploying to Vercel without understanding the 10-second function timeout on Hobby tier (use edge functions or upgrade for long operations)

Using next/image without proper sizing hints causes layout shift; always specify width/height or use fill with aspect-ratio CSS

●Ideal Project Types

SaaS applications with marketing site + authenticated dashboard
E-commerce platforms requiring SEO and dynamic inventory
Content-heavy sites (blogs, documentation, news portals)
Multi-tenant platforms with subdomain routing
Progressive web apps with offline-first capabilities
Developer tools and internal dashboards

●Complementary Technologies

TypeScript (essential for type-safe props and API contracts)
Tailwind CSS (utility-first styling with excellent tree-shaking)
Prisma or Drizzle (type-safe database access)
React Query/TanStack Query (server state management)
Zustand or Jotai (lightweight client state)
Vercel or Cloudflare Pages (optimized deployment)

●Real-World Example

Case Study

PhotoKeep Pro's marketing site demonstrates advanced Next.js patterns. The public pages use static generation with ISR (revalidate: 3600) for pricing and feature content that updates without deployments. The authenticated dashboard uses React Server Components for the photo gallery—thumbnails render server-side while the interactive editor loads client-side with dynamic imports. I implemented parallel route segments so users can open a photo detail modal (/gallery/@modal/[photoId]) without losing scroll position in the gallery. The API routes handle multipart uploads with streaming to R2 storage, with edge middleware performing JWT validation before requests hit the origin. Build time dropped from 8 minutes to 90 seconds after migrating from Pages Router by leveraging partial prerendering and on-demand ISR for user-generated content. The result: 98 Lighthouse performance score, 180ms LCP, and zero CLS.
