SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers write correct, minimal, and focused useEffect hooks in React applications, preventing common bugs related to synchronization, dependency arrays, and stale closures.

Core Features & Use Cases

  • Enforce Best Practices: Ensures adherence to React 19's useEffect and useEffectEvent guidelines.
  • Dependency Management: Guides users to correctly include all reactive values in dependency arrays.
  • Cleanup Logic: Promotes robust cleanup functions to prevent memory leaks and race conditions.
  • Use Case: When reviewing a React component that handles subscriptions or timers, use this Skill to ensure the effect is properly set up, cleaned up, and uses useEffectEvent for non-reactive reads.

Quick Start

Review the useEffect hook in the UserProfile component for adherence to React 19 best practices.

Frequently Asked Questions about react-useeffect

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix stale closure issues in React useEffect?▼

Fix stale closure issues in React useEffect by ensuring all reactive values are included in the dependency array and using useEffectEvent for non-reactive reads to maintain proper synchronization.

How do I write cleanup logic in React useEffect to prevent memory leaks?▼

Write cleanup logic in React useEffect by returning a function that cancels subscriptions, clears timers, or aborts fetch requests, ensuring robust resource management and preventing race conditions in components.

What is useEffectEvent in React 19 and when should I use it?▼

useEffectEvent in React 19 is a hook for non-reactive reads inside effects, allowing you to read the latest props and state without adding them to the useEffect dependency array, preventing unnecessary effect re-firing.

How do I handle client-side data fetching patterns with React useEffect?▼

Handle client-side data fetching patterns with React useEffect by applying exhaustive-deps linting, managing race conditions through cleanup functions, and isolating reactive dependencies to ensure correct data synchronization.

Why does my React useEffect run in an infinite loop?▼

Your React useEffect runs in an infinite loop when object or function dependencies are recreated on every render, requiring you to properly memoize dependencies or extract non-reactive values using useEffectEvent.

Does this approach enforce exhaustive-deps linting for custom hooks?▼

Yes, this approach enforces exhaustive-deps linting for custom hooks by requiring adherence to React 19 guidelines, ensuring all reactive values are correctly tracked and managed within the dependency array.
