Component-wrapper to determine and report children elements height
react-height
keeps things simple, therefore it does not support nested height change, it only checks immediate children change- not based on specific browser APIs, so can be used in other environments too

npm install --save react-height
yarn add react-height

(Module exposed as `ReactHeight`)
import {ReactHeight} from 'react-height';
<ReactHeight onHeightReady={height => console.log(height)}>
<div>Random content</div>
</ReactHeight>
Callback, invoked when height is measured (and when it is changed).
Function to measure your element. It receives the element as argument and defaults to el => el.clientHeight
.
One or multiple children with static, variable or dynamic height.
<ReactHeight onHeightReady={height => console.log(height)}>
<p>Paragraph of text</p>
<p>Another paragraph is also OK</p>
<p>Images and any other content are ok too</p>
<img src="nyancat.gif" />
</ReactHeight>
hidden
: PropTypes.bool (default: false)
ReactHeight can render to null as soon as height is measured.
<ReactHeight hidden={true} onHeightReady={height => console.log(height)}>
<div>Will be removed from the DOM when height is measured</div>
</ReactHeight>
All other props are applied to a container that is being measured. So it is possible to pass style
or className
, for example.
<ReactHeight onHeightReady={height => console.log(height)}
style={{width: 200, border: '1px solid red'}}
className="myComponent">
<div>
Wrapper around this element will have red border, 200px width
and `class="myComponent"`
</div>
</ReactHeight>
Currently is being developed and tested with the latest stable Node
on OSX
.
