How does it handle the migration from class components to hooks?

The skill provides a side-by-side mapping of legacy state and lifecycle methods (like componentDidMount) to their modern Hook equivalents (useState, useEffect).

Is TypeScript migration included in this skill?

Yes, it offers specific patterns for adding types to existing JavaScript components, including interfaces for Props and generic types for reusable components.

Can this skill help with React 18's new concurrent features?

Yes, it provides implementation patterns for Transitions, Suspense for data fetching, and the new Root API introduced in React 18.

Does it support automated code refactoring?

It includes specific instructions and scripts for running React codemods to automate the renaming of unsafe lifecycle methods and the conversion of JSX transforms.

Design Tools

Upgrades legacy React applications to modern standards using Hooks, concurrent features, and automated codemods.

About

This Claude Code Skill provides a comprehensive framework for modernizing aging React codebases, specifically targeting the transition from class-based components to functional components with Hooks. It guides developers through the complexities of React 16, 17, and 18 upgrades, offering precise patterns for state management migration, lifecycle method conversion, and the adoption of concurrent features like Suspense and Transitions. By integrating automated codemod strategies and TypeScript migration patterns, this skill ensures that frontend architectures become more maintainable, performant, and aligned with current industry best practices.
