TLDR:

React’s useEffect is where side effects either become a clean synchronization layer—or turn into infinite loops, stale closures, and hidden coupling. This guide explains the render/commit model, how the dependency array really works, safe async data fetching with cleanup, and practical debugging tactics. You’ll also see how Feature-Sliced Design helps keep effects isolated, reusable, and scalable in large React codebases.

TLDR:

React hooks are powerful, but without clear boundaries they can turn components into tightly coupled “logic blobs.” This architectural guide explains the core hooks, the Rules of Hooks, and the most common useEffect pitfalls—then shows how Feature-Sliced Design (FSD) helps you structure custom hooks, public APIs, and feature logic for large-scale React applications.

TLDR:

Choosing the right CSS architecture is a critical step toward building scalable and maintainable frontend applications. This article explores popular approaches such as BEM, CSS Modules, CSS-in-JS, and Tailwind CSS, and explains how Feature-Sliced Design provides a structured, long-term solution for managing styles in large, evolving codebases.

TLDR:

Design tokens provide a single source of truth for colors, spacing, typography, and motion, enabling consistent theming and scalable UI architecture. This article explores how design tokens work, how to implement them with CSS variables, and why Feature-Sliced Design is a robust foundation for managing tokens in large frontend codebases.

TLDR:

Jotai brings state management back to fundamentals: tiny atoms you can compose into a reliable dependency graph, without committing to a heavyweight global store. This article walks through atoms, derived and action patterns, async and SSR considerations, and shows how Feature-Sliced Design helps keep atomic state modular, testable, and scalable in large frontend codebases.

TLDR:

UI composition is no longer just about nesting components—it defines how scalable and maintainable a frontend system can become. This article explores modern UI composition patterns and shows how Feature-Sliced Design provides a structured, feature-driven approach to building flexible, long-term frontend architectures.

TLDR:

Excellent component design determines whether a frontend codebase scales cleanly or collapses into technical debt. This article explores the core principles behind well-designed components, from clear APIs and composition patterns to state management and testability, and shows how Feature-Sliced Design provides a practical, scalable foundation for building maintainable frontend systems.

TLDR:

Edge rendering is reshaping frontend architecture by pushing rendering logic closer to users, drastically reducing latency and enabling real-time personalization. This article explores how edge computing works, when to use it, and why Feature-Sliced Design provides a robust, scalable foundation for building maintainable edge-rendered frontend systems.

TLDR:

Recoil rethinks React state with an atomic graph of atoms and selectors instead of a single monolithic store. This article explains the core model, shows how selectors handle derived and async state, compares Recoil with Jotai, and outlines practical patterns for adopting atomic state management in large apps using Feature-Sliced Design to improve modularity, refactor safety, and team scalability.

TLDR:

A practical, expert-level guide to frontend profiling that shows how to measure, analyze, and optimize performance using Chrome DevTools, flame graphs, React Profiler, and memory tools—while leveraging Feature-Sliced Design to make performance bottlenecks easier to detect, isolate, and fix at scale.
