# @dangerousthings/react
React web components for the Dangerous Things design system — 20 themed components wrapping `@dangerousthings/web` CSS with React APIs matching `@dangerousthings/react-native` for cross-platform parity.
## Install
```bash
npm install @dangerousthings/react
```
### Peer Dependencies
```bash
npm install react react-dom @dangerousthings/tokens @dangerousthings/web
```
## Setup
Wrap your app with `DTWebThemeProvider` and import the web CSS bundle:
```tsx
import "@dangerousthings/web";
import { DTWebThemeProvider } from "@dangerousthings/react";
export default function App() {
return (
<DTWebThemeProvider brand="dt" theme="dark">
{/* your app */}
</DTWebThemeProvider>
);
}
```
The provider sets `data-brand` and `data-theme` attributes on a wrapper div and exposes brand/theme via React context.
