This Skill helps teams modernize React applications by upgrading core React versions, migrating from class components to functional components with hooks, and adopting concurrent features to improve UX and performance.

Core Features & Use Cases

Upgrades React to latest stable versions and adjusts related APIs.
Migrates class components to hooks using useState, useEffect, and useContext patterns.
Enables concurrent features such as Suspense, transitions, and the new root API.
Provides codemods for automated refactoring and optional TypeScript migration.

Quick Start

Install the modernization tooling and run the transformation commands on your src/ directory to migrate classes to hooks and upgrade to the latest React versions.

FAQPage Schema

How do I migrate React class components to hooks?▼

Migrate class components to hooks by converting lifecycle methods to useEffect, state to useState, and context to useContext. This Skill automates the migration using codemods, transforming your codebase from class-based to functional component patterns while maintaining functionality.

Can I upgrade React 16 or 17 to React 18 automatically?▼

Yes, this Skill automates React version upgrades from 16 or 17 to 18, adjusting APIs and dependencies automatically. It handles the upgrade process and prepares your codebase for concurrent features like Suspense and transitions.

What are React Suspense and transitions, and when should I use them?▼

Suspense lets components wait for data before rendering; transitions defer non-urgent updates to keep the UI responsive. These concurrent features improve performance and user experience. This Skill enables them during modernization by updating your React version and component structure.

Do I need TypeScript to use this modernization tool?▼

TypeScript is optional. This Skill performs JavaScript codemod transformations by default and offers optional TypeScript migration as part of the modernization process. Your existing JavaScript codebase works without it.

What environment and tools are required to run the modernization?▼

You need Node.js and npm or yarn installed. The Skill runs transformation commands on your src/ directory using codemods and automated refactoring tools to update your React codebase in place.

Can this handle large or complex React applications?▼

This Skill targets projects of any size upgrading from React 16/17 to 18. It uses automated codemods to scale across large codebases, though complex custom patterns may require manual review after automated transformation.
