[ Platform service ]

Next.js Development — built properly, handed over completely.

Fast, search-ready Next.js applications using App Router, server rendering, Cache Components, headless content, and reliable edge deployment.

CATEGORY Web DevelopmentSTACK 3 platform tagsPROOF 2 case studies available

[ What you get ]

5 deliverables. Nothing implicit.

Application architecture: Rendering strategy, routing, and content sources decided up front — server components, caching model, and data access recorded before code.You own: An architecture decision record plus the repository
CMS & API integration: Content and data wired into server components with failure states handled, not bolted on later.You own: Working integrations with their contracts documented
Performance budget: Core Web Vitals measured against the agreed budget, with preview deployments verifying every increment.You own: A CWV report against budget plus the CI checks that enforce it
UI build: The interface implemented from the design system, with responsive and accessibility checks as each screen lands.You own: The production frontend in your repository
Handover: Repository, environment configuration, deployment pipeline, and operating documentation transferred.You own: The repo, the pipeline, and a runbook your team can operate
Done means: Done means the app deploys from your repository on every merge, Core Web Vitals sit inside the budget on real templates, and another competent team could pick up the code from the docs alone.
Not included: Vercel or hosting fees, CMS subscriptions, and ongoing product management are yours; we build and hand over the system.

[ How it works ]

The next.js development engagement, phase by phase.

Architecture & data planning: Rendering strategy, routing, and content sources are decided up front — App Router conventions, server components, and the caching model recorded before code.
Build & integration: The application is built in reviewable increments, wiring the CMS and APIs into server components instead of bolting them on later.
Performance budget & QA: Core Web Vitals are measured against the agreed budget, with preview deployments used to verify every increment before merge.
Handoff: Your team receives the repository, environment configuration, deployment pipeline, and documentation for operating the app without us.

[ Capabilities ]

The surface area of a next.js development build.

The platform and discipline surface we work across — what an engagement can cover when the scope calls for it.

App Router & layouts

Route groups, nested layouts, and streaming server components used deliberately.

Server & client boundaries

The split decided per feature — data stays on the server until it must move.

Caching & revalidation

Request caching, revalidation tags, and invalidation that keeps content fresh.

Data fetching & mutations

Server Actions and route handlers with typed contracts and error states.

Headless CMS integration

Content sourced from your CMS with preview and draft flows intact.

Image & font optimization

next/image, font subsetting, and the asset pipeline behind the budget.

Metadata & SEO

Per-route metadata, sitemaps, structured data, and Open Graph generation.

Edge & middleware

Redirects, auth gates, and path logic where the edge is the right place.

Testing & CI

Type checks, lint, and smoke tests wired so merges cannot regress the budget.

Analytics & monitoring

Web vitals reporting and error tracking on the surfaces your team reads.

[ Field notes ]

How we think about next.js development.

Why Next.js for modern applications: Next.js gives you a framework where rendering strategy is a decision, not a limitation, with server rendering, static generation, and ISR all available per route. That flexibility is what makes fast, search-ready applications possible.
Who the Next.js service is for: This is for product and marketing teams that need a performant web application with real content demands. It suits teams that already work headlessly or want to leave a legacy CMS for a composable content setup.
The Next.js deliverables: Deliverables include the application architecture, CMS and API integration, a performance budget, and preview deployments. These cover the structural decisions, data wiring, and the verification that keeps quality in check.
Discovery: architecture and headless strategy: We begin by mapping the application routes and data sources so the architecture fits the content. This phase decides how headless content will be consumed and where the performance budget needs to land.
App Router, layouts and routing: The app is built on the App Router with layouts, routing, dynamic segments, route handlers, and middleware organizing every page. Shared layout structure keeps navigation state and shell UI consistent across routes.
React Server Components and client components: RSC keeps data-heavy rendering on the server while client components handle interactivity where it is actually needed. That split reduces JavaScript shipped to the browser and keeps pages fast to first render.
Rendering strategies, Cache Components and ISR: Each route gets a rendering strategy chosen from server-side rendering, static generation, Cache Components, or ISR based on how often its data changes. In current Next.js 16, use cache with cacheLife and cacheTag can make caching intent explicit, while Partial Prerendering remains a performance option where the architecture supports it. ISR stays one useful option rather than the only freshness model.
CMS and API integration: Headless content is wired in through CMS and API integration, with data fetched through the framework's native patterns. This keeps editorial teams on their CMS while the Next.js app owns the presentation.
Metadata, Image and Link components: The Metadata API gives search engines accurate page titles, descriptions, and social metadata. The Image and Link components add automatic optimization, lazy loading, and preloading for a search-ready front end.
Vercel, edge runtime and preview deployments: Deployment targets Vercel with the edge runtime where low-latency execution matters. Preview deployments give every change its own URL for review before it reaches production.
Performance budget and Core Web Vitals: The performance budget anchors the work in Core Web Vitals so speed is measured, not assumed. Bottlenecks are addressed during the build rather than discovered after launch.
Launch, enablement and related services: Launch confirms preview deployments, production deploys, and the performance budget hold under real traffic. Follow-on work includes expanding route coverage, adding content sources, and evolving the architecture with TypeScript as the app grows.

[ Common questions ]

Which rendering strategy do you use?

It is per-route: server-side rendering, static generation, Cache Components with use cache, or ISR are chosen based on how often each piece of content changes and how the route should stream or revalidate.

How is content integrated?

Through headless CMS and API integration, with data fetched using the framework's native patterns so editors stay in their CMS.

What are preview deployments?

Every change gets its own URL via preview deployments on Vercel, so it can be reviewed before it ships to production.

Is the app built with TypeScript?

Yes. TypeScript is used throughout so the routes, components, and CMS data shapes stay safe as the application grows.

How is performance verified?

Performance is enforced with a budget tied to Core Web Vitals, checked during the build and again at launch.
