# react-viewer
[![NPM version][npm-image]][npm-url]
> react image viewer.
## Introduction
Because i can`t comfortable use [viewerjs](https://github.com/fengyuanchen/viewerjs) in react, so i create react-viewer to replace it.
## Installation
```bash
npm install react-viewer --save
```
## Usage
```javascript
import * as React from 'react';
import Viewer from 'react-viewer';
import 'react-viewer/dist/index.css';
class App extends React.Component<any, any> {
constructor() {
super();
this.state = {
visible: false,
};
}
render() {
return (
<div>
<button onClick={() => { this.setState({ visible: !this.state.visible }); } }>show</button>
<Viewer
visible={this.state.visible}
onClose={() => { this.setState({ visible: false }); } }
images={[src: '', alt: '']}
/>
</div>
);
}
}
```
