RĂ©sultat attendu:

React 18 createRoot API with proper container element selection and error boundary setup

Utilisation de "react-modernization". Synchronous state updates in event handler

RĂ©sultat attendu:

Transition-wrapped state updates for non-urgent UI changes with isPending loading indicator

v1 ‱ 2/24/2026

Static analyzer flagged 48 patterns but all are false positives. This skill contains documentation-only markdown files with React code examples. Dynamic imports are standard React lazy() patterns, shell commands are documentation for codemod usage, and fetch calls are example code snippets. No executable code exists in this skill.

Ce que vous pouvez construire

Legacy React Application Upgrade

Upgrade an older React 16 application to React 18 with automatic batching and concurrent features

Class to Hooks Migration

Convert class components with lifecycle methods to modern functional components using useState and useEffect

Performance Optimization

Implement code splitting, memoization, and Suspense boundaries for improved application performance

Essayez ces prompts

Basic Hooks Conversion 
Convert this React class component to use hooks. Identify state variables and lifecycle methods to transform into useState and useEffect.
Version Upgrade Assessment 
Analyze my React codebase for breaking changes when upgrading from React 17 to 18. List all files that need modifications and provide a migration checklist.
Codemod Automation 
Generate commands to run React codemods for my project. Include jscodeshift installation, specific transforms for lifecycle methods, and the new JSX transform.
Concurrent Features Implementation 
Refactor this search component to use useTransition for non-urgent updates. Show how to implement Suspense boundaries for data fetching with proper loading states.

Bonnes pratiques

  • Migrate incrementally starting with leaf components that have no children
  • Run comprehensive tests after each migration step to catch regressions early
  • Use React StrictMode to identify unsafe patterns and side effects during development

Éviter

  • Adding useMemo or useCallback without measuring actual performance problems
  • Forgetting to include all dependencies in useEffect dependency arrays
  • Mixing class component patterns with hooks in the same component

Foire aux questions

Do I need to migrate all components at once?
No. React supports mixing class and functional components. Migrate incrementally, starting with simpler leaf components.
Will codemods handle all the migration automatically?
Codemods automate repetitive transformations but cannot handle complex logic. Manual review and testing are still required.
What is the minimum React version for hooks?
Hooks require React 16.8 or later. If on an older version, upgrade to 16.8+ first before migrating to hooks.
Are there performance concerns with React 18 automatic batching?
Automatic batching improves performance by reducing re-renders. Use flushSync only if you need immediate DOM updates.
How do I handle cleanup in useEffect?
Return a cleanup function from useEffect that cancels subscriptions, aborts fetch requests, or clears timers.
Can I use Suspense for data fetching in production?
Suspense for data fetching is stable in React 18 but requires compatible data fetching libraries or custom implementations.
