Next.js Development Agency & Consulting in the UK
We engineer high-performance web applications, enterprise platforms, and commercial websites using Next.js App Router, React Server Components, and modern TypeScript.
Common Pitfalls in Modern Next.js Implementations
Next.js is extraordinarily powerful, but incorrect architectural patterns cause sluggish rendering, client-side watermarks, and caching headaches.
'use client' Overuse & Massive Bundles
Slapping 'use client' at the top of every file turns Next.js into a bloated Single Page App, destroying server-side rendering and inflating JavaScript bundle sizes.
Stale Data & Broken Revalidation
Misconfigured fetch caches and ISR tags that show outdated data to users or cause random server memory leaks.
Layout Shifts (CLS) & Interaction Lag (INP)
Unoptimized web fonts, layout reflows, and heavy JavaScript execution blocking the main thread.
Engineered Next.js Architecture: Senior-Level Rigor
We build Next.js applications that are blazing fast, robustly typed, and effortless to maintain.
App Router & Server Component Mastery
Keep 80% of your application logic on the server. Minimal client JavaScript, instant first-contentful paint, and streaming UI with Suspense boundaries.
- Pure React Server Components (RSC) for heavy data logic
- Targeted client interactivity with state machines and hooks
- Streaming UI fallbacks with Suspense and loading states
Core Web Vitals & Technical SEO Optimization
Deep profiling and optimization of Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).
- Next.js Image and Font optimization with zero layout shift
- Dynamic JSON-LD schema injection and automated XML sitemaps
- Server-side Edge rendering with stale-while-revalidate caching
Legacy React & WordPress to Next.js Migrations
Seamlessly migrate your existing digital properties to Next.js without losing historical SEO rankings or user traffic.
- URL structure and 301 redirect map preservation
- Headless CMS integration (Sanity, Strapi, Supabase)
- Automated regression and Playwright end-to-end testing
