Install
yarn add react-scrolllockUsage
import ScrollLock, { TouchScrollable } from 'react-scrolllock';
class Modal extends Component {
state = { lockScroll: false }
render() {
return (
<div>
...
// the lock accepts a single child element, which supports touch-scrolling.
<ScrollLock>
<ElementWithScrollableContent>...</ElementWithScrollableContent>
</ScrollLock>
// if your app structure doesn't allow wrapping like above, the `TouchScrollable`
// component is exposed as a named export.
<ScrollLock />
<TouchScrollable>
<ElementWithScrollableContent>...</ElementWithScrollableContent>
</TouchScrollable>
// you can also toggle the lock based on some state.
<ScrollLock isActive={this.state.lockScroll} />

ScrollLock
| Property | Description |
|---|---|
accountForScrollbars boolean
|
Default: true -- Whether or not to replace the scrollbar width when active. |
isActive boolean
|
Default: true -- Whether or not the lock is active. |
children element

TouchScrollable
Wrap an element in the TouchScrollable component if you need an area that supports scroll on mobile.
This is necessary because the touchmove event is explicitly cancelled — iOS doesn't observe overflow: hidden; when applied to the <body /> element
