Explicit `/react-dev` reference for advanced React/TypeScript typing and integration patterns. Do not auto-use for routine React implementation.
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 TypeScript
Type-safe React = compile-time guarantees = confident refactoring.
<when_to_use>
- Building typed React components
- Implementing generic components
- Typing event handlers, forms, refs
- Using React 19 features (Actions, Server Components, use())
- Router integration (TanStack Router, React Router)
- Custom hooks with proper typing
NOT for: non-React TypeScript, vanilla JS React
</when_to_use>
<react_19_changes>
React 19 breaking changes require migration. Key patterns:
**ref as prop** - forwardRef deprecated:
```typescript
// React 19 - ref as regular prop
type ButtonProps = {
ref?: React.Ref<HTMLButtonElement>;
} & React.ComponentPropsWithoutRef<'button'>;
function Button({ ref, children, ...props }: ButtonProps) {
return <button ref={ref} {...props}>{children}</button>;
}
```
**useActionState** - replaces useFormState:
```typescript
import { useActionState } from 'react';
type FormState = { errors?: string[]; success?: boolean };
function Form() {
const [state, formAction, isPending] = useActionState(submitAction, {});
return <form action={formAction}>...</form>;
}
```
**use()** - unwraps promises/context:
```typescript

How to install
mdr add dannykkh/skill-olympus/react-dev@sha256:9226430438b9d8d7The line at the top of this page pins the label v1.0.0, 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.
