Upgrade React applications to latest versions, migrate from class components to hooks, and adopt concurrent features. Use when modernizing React codebases, migrating to React Hooks, or upgrading to latest React versions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Modernization
Master React version upgrades, class to hooks migration, concurrent features adoption, and codemods for automated transformation.
## When to Use This Skill
- Upgrading React applications to latest versions
- Migrating class components to functional components with hooks
- Adopting concurrent React features (Suspense, transitions)
- Applying codemods for automated refactoring
- Modernizing state management patterns
- Updating to TypeScript
- Improving performance with React 18+ features
## Version Upgrade Path
### React 16 → 17 → 18
**Breaking Changes by Version:**
**React 17:**
- Event delegation changes
- No event pooling
- Effect cleanup timing
- JSX transform (no React import needed)
**React 18:**
- Automatic batching
- Concurrent rendering
- Strict Mode changes (double invocation)
- New root API
- Suspense on server
## Class to Hooks Migration
### State Management
```javascript
// Before: Class component
class Counter extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0,
name: "",
};
}
increment = () => {
this.setState({ count: this.state.count + 1 });
};
render() {

How to install
mdr add dicklesworthstone/pi_agent_rust/react-modernization@sha256:e9b2baa36b652ea1The line at the top of this page pins the label git:20260205.788be98, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
