SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill solves the common React hook problems of unnecessary re-renders, stale closures, infinite loops, and noisy biome exhaustive-deps warnings by standardizing how custom hooks and Context providers should be structured in this project.

Core Features & Use Cases

  • Custom hook design rules: Extract hooks only when there is real duplication, follow naming/return-value conventions, and favor stable references with useCallback/useMemo.
  • Context splitting guidance: Use separate State and Actions contexts so action-only consumers don’t re-render when state changes.
  • Effect and dependency correctness: Use effects only for external synchronization (WebSocket, timers, subscriptions) and derive render-time data during render or with memoization; align with biome useExhaustiveDependencies and safe ref/callback patterns.
  • Testing conventions for hooks: Test custom hooks with @testing-library/react using renderHook and act, without calling hooks directly.

Quick Start

Apply the react-hooks guidelines to refactor a Context provider by splitting state vs actions, then fix any biome exhaustive-deps warnings in its effects using the documented dependency and ref patterns.

FAQPage Schema
How do I fix biome useExhaustiveDependencies warnings in React hooks?▼

Fix biome useExhaustiveDependencies warnings by applying safe ref and callback patterns, using effects only for external synchronization, and deriving render-time data during render or with memoization to align dependencies correctly.

Why do my React Context providers cause unnecessary re-renders?▼

React Context providers cause unnecessary re-renders when state and actions share a single context. Split them into separate State and Actions contexts so action-only consumers don't re-render when state changes.

When should I extract a custom hook in React?▼

Extract a custom hook in React only when there is real duplication. Follow naming and return-value conventions, and favor stable references using useCallback and useMemo to prevent inefficient re-render patterns.

How do I test custom React hooks with renderHook and act?▼

Test custom React hooks with @testing-library/react by using renderHook and act utilities. Never call hooks directly; always render them within a component testing wrapper to ensure correct execution behavior.

Does this React hooks guideline work for React 19 projects?▼

Yes, this React hooks guideline works for React 19 projects. It enforces correct dependency, ref, and callback patterns specifically aligned with biome useExhaustiveDependencies to prevent stale closures and infinite loops.
