• React Performance Patterns: Rendering, Memoization, and Scheduling

  Frontend Engineering / React Architecture 13 min read

  Patterns for keeping React applications fast as they scale: understanding the render pipeline, applying memoization correctly, leveraging concurrent features, and profiling effectively. Covers React 18+ with notes on React 19 and the React Compiler.

• React Hooks Advanced Patterns: Specialized Hooks and Composition

  Frontend Engineering / React Architecture 14 min read

  Advanced hook APIs, performance patterns, and composition techniques for concurrent React applications. Covers useId, use, useLayoutEffect, useSyncExternalStore, useInsertionEffect, useDeferredValue, and useTransition—hooks that solve specific problems the core hooks cannot.

• React Rendering Architecture: Fiber, SSR, and RSC

  Frontend Engineering / React Architecture 15 min read

  React’s rendering architecture has evolved from a synchronous stack-based reconciler to a sophisticated concurrent system built on Fiber’s virtual call stack. This article examines the Fiber reconciliation engine, lane-based priority scheduling, streaming Server-Side Rendering (SSR), and React Server Components (RSC)—now stable as of React 19 (December 2024). Understanding these internals is essential for making informed architectural decisions about rendering strategies, performance optimization, and infrastructure requirements.

• React Hooks Fundamentals: Rules, Core Hooks, and Custom Hooks

  Frontend Engineering / React Architecture 15 min read

  React Hooks enable functional components to manage state and side effects. Introduced in React 16.8 (February 2019), hooks replaced class components as the recommended approach for most use cases. This article covers the architectural principles, core hooks, and patterns for building production applications.
