SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

React 18 introduces hooks, concurrent features, and advanced patterns that require careful review to ensure correctness, performance, and maintainability. This skill provides structured guidelines to assess and improve React 18 codebases.

Core Features & Use Cases

  • Hooks Best Practices: verify Rules of Hooks, correct dependency arrays, and proper custom hook naming.
  • State Management: promote useState/useReducer patterns and avoid unnecessary prop drilling.
  • Concurrent Features: evaluate useTransition, useDeferredValue, and Suspense usage for responsiveness and correctness.
  • Suspense and Data Fetching: ensure boundaries and error handling are in place.
  • Performance Optimization: recommend memoization, stable callbacks, and avoiding unnecessary renders.
  • Component Patterns & Testing: encourage typed function components and RTL based tests. Use Case: When reviewing a React 18 app, apply these guidelines to improve reliability and performance across components, hooks, and data flows.

Quick Start

Run this skill against your React 18 project to identify hook, concurrency, and performance issues and apply recommended improvements.

FAQPage Schema
How do I review React 18 hooks for correct dependency arrays and performance?

Review React 18 hooks by validating dependency arrays, enforcing Rules of Hooks, and checking custom hook naming to ensure correct state management and avoid unnecessary renders. Apply these checks across components and data fetching patterns to improve reliability and performance.

What is the best way to use React 18 concurrent features like useTransition and useDeferredValue?

Evaluating React 18 concurrent features involves assessing useTransition, useDeferredValue, and Suspense usage to ensure UI responsiveness and correctness. Proper implementation requires validating boundaries and error handling during data fetching and rendering optimization tasks.

How do I optimize React 18 rendering performance with memoization and stable callbacks?

Optimize React 18 rendering performance by recommending proper memoization, verifying stable callbacks, and avoiding unnecessary renders across components. Review these patterns within typical app scenarios like data fetching and form handling to enforce best practices.

Can I use TypeScript to enforce React 18 component patterns and state management?

Yes, you can enforce React 18 component patterns by validating proper typing with TypeScript, encouraging typed function components, and promoting useState or useReducer patterns to avoid unnecessary prop drilling and ensure maintainability.

When do I need Suspense boundaries for React 18 data fetching?

You need Suspense boundaries for React 18 data fetching when evaluating concurrent features to ensure proper error handling is in place. Review these boundaries alongside useTransition and useDeferredValue to maintain UI responsiveness during asynchronous operations.
