React makes it easy to start with a component; the harder work is deciding how that component should behave as the application grows. These articles follow rendering and state across component and API boundaries, with an eye on the trade‑offs that keep a long‑lived codebase understandable.

Mastering Server Components in Next.js, including client boundaries, data fetching, caching, streaming, and the mistakes that make App Router code messy.

Debug stale Next.js App Router pages with cache tags, revalidation paths, CMS webhooks, preview freshness, dependency graphs, and simpler cache contracts.

A Pages Router to App Router migration checklist for Next.js teams, covering routing, data fetching, caching, metadata, server components, and rollout.

React developer vs. Next.js developer explained through production concerns: rendering, routing, caching, SEO, deployment, CMS data, and debugging.

Memoisation helps JavaScript functions run faster by caching previous results. Here's a clear guide on how and when to use memoisation effectively.

Compare client‑side React caching, Next.js SSG, ISR and SSR caching, and Redis‑backed caches for reliable serverless data fetching and persistence.

Why JavaScript pages get crawled but not indexed, covering rendered content, metadata, canonicals, links, noindex rules, quality, and crawl signals.

A React SPA to Next.js SEO migration checklist for preserving indexing, redirects, metadata, rendered HTML, internal links, crawl paths, and launch confidence.

React's virtual DOM describes the UI before reconciliation updates the browser DOM. I explain the costs, list keys and why performance still needs measuring.

useMemo and useCallbackOptimise React performance with useMemo and useCallback only where profiling shows expensive calculations, unstable functions, or avoidable re‑renders.

Memory leaks in React can cause sluggish performance and excessive memory usage. Here, I explore common causes, how to prevent them, and debugging techniques.

Higher‑Order Components (HOCs) in React wrap components to enhance functionality. Here, I explore how HOCs work, common use cases, and when to use them.

React's reconciliation algorithm updates the UI by comparing the virtual DOM with the previous state. I explore how it works and why it improves performance.

A retrospective on React component APIs before hooks settled, covering render props, higher‑order components, context, classes, and migration judgement.

styled-componentsUse transient props in styled-components to keep styling‑only props out of the DOM, clean React output, and support safer component migration work.

Add seeded randomisation to an SSR Gatsby project, keeping content order deterministic across builds whilst still rotating destination‑style content.


useEffect HookUnderstand the empty dependency array in React's useEffect, including after‑commit setup, cleanup, remounts, development checks and reactive dependencies.
