Headless UI patterns consistently separate interaction logic from visual presentation, so teams can implement their own design without compromising keyboard control or ARIA semantics. Once you understand how custom hooks, compound components and state machines work together, many use cases no longer need an external headless library at all.

Components that handle data fetching, form validation and UI state all at once are hard to test, hard to maintain and hard to reuse. Custom Hook Extraction is the fundamental React pattern that separates logic from presentation, making both better at the same time.

The question of React Native versus PWA cannot be answered in general terms, it depends on concrete product requirements: app store visibility, access to native hardware, offline behavior and available budget. This article provides a structured decision framework based on real technical limits rather than marketing promises.

React 19 brings new hooks and refines existing ones, but the biggest problem in practice is not a lack of knowledge, it is the wrong choice: useEffect where useRef would suffice, useMemo where no memoizing is needed at all. This cheat sheet gives clear decision rules for when which React hook is the right one.

The choice between Framer Motion and CSS Transitions in React has more to do with the animation type than with personal preference. Hover effects and simple state transitions belong in CSS. Orchestrated sequences, exit animations and shared element transitions are barely achievable without Framer Motion. This tutorial explains when which solution is the right one.

PWA Studio ships a ready-made Peregrine architecture with prebuilt components, while a custom React frontend gives full control over design, bundle size and dependencies. The decision depends less on trends than on team size, timeline and how individual the required shop experience needs to be.

React Fiber is not just an internal implementation detail, it is the foundation of why React 18, with Concurrent Mode, useTransition and Suspense, renders applications in a fundamentally different way than every version before it. Anyone who wants to understand why some updates are more urgent than others, and how React decides what appears on screen next, needs to know Fiber and its priority system.

Create React App is officially deprecated and no longer maintained. Vite has taken over as the standard for React tooling: natural ESM in the dev server, sub-100ms hot module replacement, and a configuration that never requires ejecting. This article explains why the switch is worth it and how it goes smoothly.

Three lightweight alternatives to Redux, three different mental models. Recoil and Jotai rely on atoms as the smallest unit of state, Zustand relies on a single central store. This article compares bundle size, server state integration and maintenance status, so the choice rests on concrete criteria instead of gut feeling.

The choice of platform for a React deployment decides build times, cost and control. Vercel, Netlify and a self-operated Docker stack solve the same problem with different trade-offs. This article shows concrete configurations, a CI/CD pipeline and the decision criteria for each situation.
