React Scroll Lock Configurable
Prevent scroll on the <body /> when a component is mounted.

Note from developer

This library is a fork of react-scrolllock by jossmac with ability to accept options object which will override some touch handlers. It is useful if you want to have vertical scroll locked while allowing for horizontal scroll or in cases where some of your children require horizontal scroll to work (which original package doesn't allow because of aggressive event capturing and propagation prevention)

Forked NPM Package

Install

yarn add react-scrolllock-configurable

Usage

import ScrollLock, { TouchScrollable } from 'react-scrolllock-configurable';

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} />
      </div>
    );
  }
}

Props

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 | Default: null -- This element is wrapped internally by the TouchScrollable component. |

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 😢
| Property | Description | | :----------------------- | :--------------------------------------------- | | children element | Required The element that can be scrolled. | | options object | Optional Provide an options object |
Options 
Options object can have `onTouchMove` and `onTouchStart` event handlers if you need to unblock scrolling 
{
  onTouchMove: (event) => {}
  onTouchStart: (event) => {}
}
