    npm install @yudiel/react-qr-scanner

### Usage

```jsx
import {QrScanner} from '@yudiel/react-qr-scanner';

const App = () => {
  return (
      <QrScanner
          onDecode={(result) => console.log(result)}
          onError={(error) => console.log(error?.message)}
      />
  );
}
```

### Supported Formats

### Limitations
- Due to browser implementations the camera can only be accessed over https or localhost.
- Server side rendering won't work so only require the component when rendering in a browser environment.
