### Installation

```
yarn add react-qr-code
```

When using this library with React Native, you will also need to [have `react-native-svg` installed](https://github.com/react-native-svg/react-native-svg#installation).

```
yarn add react-native-svg
cd ios && pod install
```

### The Gist

```javascript
import React from "react";
import ReactDOM from "react-dom";
import QRCode from "react-qr-code";

ReactDOM.render(<QRCode value="hey" />, document.getElementById("Container"));
```

Note: If the QR code is likely to appear next to dark objects, you will need to wrap it in a light-colored container to preserve the '[quiet zone](https://qrworld.wordpress.com/2011/08/09/the-quiet-zone/)', e.g. 
```javascript
<div style={{ background: 'white', padding: '16px' }}>
    <QRCode ... />
</div>
```
