React-Scrollbar-Size

React-Scrollbar-Size is a React component designed to calculate the size of the user agent's horizontal and vertical scrollbars. It will also detect when the size of the scrollbars changes, such as when the user agent's zoom factor changes.

Installation

React-Scrollbar-Size is available as an npm package:

$ npm install --save react-scrollbar-size

Usage

Props

Name	Description
onLoad	Callback which will fire when the component mounts.
onChange	Callback which will fire when the scrollbar sizes change.

Each of the callbacks accepts an object which will be updated with the following properties:

Name	Description
scrollbarWidth	The current width of the vertical scrollbar.
scrollbarHeight	The current height of the horizontal scrollbar.

Example

import React, { Component } from 'react';
import ScrollbarSize from 'react-scrollbar-size';

class MyComponent extends Component {
  scrollbarSizeLoad = (measurements) => {
    console.log('Scrollbars loaded', measurements);
  }

  scrollbarSizeChange = (measurements) => {
    console.log('Scrollbars changed', measurements);
  }

  render() {
    return (
      <div>
        <ScrollbarSize
          onLoad={this.scrollbarSizeLoad}
          onChange={this.scrollbarSizeChange}
        />
