METHOD

The intersection of rendering, data and distribution

Every route is treated on its own: what renders on the server, where the data lives, and from which region it ships. The site scales on the same codebase when the traffic arrives.

01 / 03

Design

Route map with RSC segments and Client Components
Data model aligned with Server Actions and Route Handlers
Per-route caching strategy: SSG, ISR, SSR or dynamic
SEO plan with Metadata API, Open Graph and structured data

02 / 03

Development

App Router with nested layouts and per-segment loading.tsx
Server Components by default, client only where it pays off
Server Actions typed with end-to-end TypeScript
next/image and next/font to ship only what the browser needs

03 / 03

Optimization

Edge runtime on critical routes and geo-aware middleware
ISR with cache tags and on-demand revalidation
OpenTelemetry wired to Sentry and Vercel Analytics
Lighthouse and Web Vitals in CI with per-route budgets

USE CASES

When Next.js is the clear choice

Four scenarios where the Next.js model unlocks performance, SEO and velocity on the same React codebase.

Headless e-commerce

DTC · STOREFRONTS

Storefronts wired to Shopify, commercetools or Sanity, with the catalog cached on ISR and checkout dynamic at the Edge. Fast PDPs in every region.

Catalog conversion and SEO on top of the existing commerce backend.

Brand sites with ISR

MARKETING · CONTENT

Landings and corporate home served as static with on-demand revalidation from the CMS. Editorial changes go live in seconds.

Low TTFB and instant publishing from the content team.

SaaS with mixed dashboards

RSC + CSR

Public areas on RSC for SEO and authenticated sections on the client with React Query or tRPC. Server Actions for typed mutations.

One codebase for the public site and the internal product.

Documentation portals

MDX · CMS

Docs and content hubs with MDX, integrated search and segment navigation. Full indexing and solid internal linking.

Documentation that ranks and stays current from Git or the CMS.

STANDARDS

How we write Next.js in production

Rules we apply on every Next.js project to sustain performance, SEO and maintainability as the site grows.

App Router with nested layouts and route groups per domain
React Server Components by default, 'use client' only where it pays off
Metadata API with titles, OG and structured data per route
next/image, next/font and dynamic imports for per-route JS budgets
ISR with cache tags and on-demand revalidation from the CMS
Edge runtime on middleware and geo-sensitive routes
Server Actions typed with Zod and end-to-end TypeScript
OpenTelemetry, Sentry and Web Vitals wired into CI
Lighthouse ≥ 95 on performance and SEO on every deploy

QUESTIONS

Frequent questions about Next.js

What a technical team usually asks before picking Next.js for a public site or a SaaS product.

App Router or Pages Router on new projects?
We start new projects on App Router. It enables React Server Components, nested layouts, streaming and Server Actions, and concentrates the Next team's roadmap. Pages Router stays for maintenance of existing apps with route-by-route migration.
What real limitations do Server Components have?
Server Components render on the server and accept no state, effects or event handlers. We follow a clear pattern: RSC for data and composition, Client Components for interaction. Libraries that depend on the DOM are isolated in small, focused 'use client' components.
Vercel or self-hosting?
We deploy on Vercel when the team prioritizes global Edge, ISR and per-PR previews with managed ops. For regulated workloads or sensitive data, we use the standalone output on Docker, Kubernetes or AWS, keeping ISR, streaming and HTTP cache through our own CDN.
When to pick SSG, ISR or SSR?
SSG for pages with stable content and a low change rate. ISR for catalog, blog and landings with frequent publishing: cached HTML and on-demand revalidation. SSR for routes with per-user data or real-time queries. The choice is made route by route based on content behavior.
When Next.js and when plain React or Vite?
Next.js fits public sites, e-commerce, marketing and SaaS with indexable areas: SEO, TTFB and SSR weigh on the decision. For back-office and internal SPAs behind login, Vite with plain React tends to be simpler, faster to start and cheaper to operate.
How do you handle i18n in App Router?
We use next-intl with per-locale segments ([locale]/...), per-language sitemap and robots, and Metadata API with alternates and hreflang. Translations live in versioned JSON and are served from Server Components, keeping the client bundle close to zero on static routes.
