react-viewer v3.2.2
react-viewer
react image viewer.
Introduction
Because I can`t be comfortable using viewerjs in react, so I created react-viewer to replace it.
Installation
react >= 16.8.0 | react-dom >= 16.8.0
npm install react-viewer --save
Usage
import * as React from 'react';
import Viewer from 'react-viewer';
function App() {
const [ visible, setVisible ] = React.useState(false);
return (
<div>
<button onClick={() => { setVisible(true); } }>show</button>
<Viewer
visible={visible}
onClose={() => { setVisible(false); } }
images={[{src: '', alt: ''}]}
/>
</div>
);
}
Server Side Rendering
I'm sorry, ssr is not currently supported in 3.x
, it will be fixed in 4.0
.
