Introduction

Custom scrollbars in React can significantly enhance the user experience by providing a tailored and interactive interface. The react-custom-scrollbars library offers a comprehensive solution for creating custom scrollbars that are fully customizable, frictionless, and performant. In this article, we will explore the features, installation, basic usage, and advanced customization options of this library.

Features

The react-custom-scrollbars library boasts several key features that make it a powerful tool for developers:

  • Frictionless Native Browser Scrolling: The library ensures that scrolling is handled natively by the browser, providing a seamless and smooth experience.
  • Native Scrollbars for Mobile Devices: The scrollbars are optimized for mobile devices, ensuring that they function correctly and efficiently on these platforms.
  • Fully Customizable: The scrollbars can be customized extensively, allowing developers to tailor them to their specific needs.
  • Auto Hide: The scrollbars can be automatically hidden when not in use, enhancing the overall user experience.
  • Auto Height: The scrollbars can adjust their height dynamically based on the content, providing a clean and organized interface.
  • Universal Rendering: The library supports rendering on both client and server sides, making it versatile for various application scenarios.
  • High Performance: The library uses requestAnimationFrame for 60fps rendering, ensuring that the scrollbars update synchronously with the browser’s render flow.
  • No Extra Stylesheets: The library does not require additional stylesheets, allowing developers to style the scrollbars using their existing CSS.

Installation

To install the react-custom-scrollbars library, you can use npm or yarn:

npm install react-custom-scrollbars --save

Alternatively, if you prefer a single-file UMD build, you can grab a pre-built version from unpkg:

npm install react-custom-scrollbars@4.2.1

Basic Usage

The basic usage of the react-custom-scrollbars library is straightforward. Here is a simple example:

import { Scrollbars } from 'react-custom-scrollbars';

class App extends Component {
  render() {
    return (
      <Scrollbars style={{ width: 500, height: 300 }}>
        <p>Some great content...</p>
      </Scrollbars>
    );
  }
}

In this example, we import the Scrollbars component and use it to wrap a piece of content. The style prop is used to set the width and height of the scrollbars.

Advanced Usage

The react-custom-scrollbars library offers a wide range of props that can be used to customize the scrollbars. Here is an example of advanced usage:

import { Scrollbars } from 'react-custom-scrollbars';

class CustomScrollbars extends Component {
  render() {
    return (
      <Scrollbars
        onScroll={this.handleScroll}
        onScrollFrame={this.handleScrollFrame}
        onScrollStart={this.handleScrollStart}
        onScrollStop={this.handleScrollStop}
        onUpdate={this.handleUpdate}
        renderView={this.renderView}
        renderTrackHorizontal={this.renderTrackHorizontal}
        renderTrackVertical={this.renderTrackVertical}
        renderThumbHorizontal={this.renderThumbHorizontal}
        renderThumbVertical={this.renderThumbVertical}
        autoHide
        autoHideTimeout={1000}
        autoHideDuration={200}
        autoHeight
        autoHeightMin={0}
        autoHeightMax={200}
        thumbMinSize={30}
        universal={true}
        {...this.props}>
      </Scrollbars>
    );
  }
}

In this example, we define a custom CustomScrollbars component that uses various props to customize the scrollbars. These props include event handlers for scrolling, rendering functions for the scrollbar components, and options for auto hide, auto height, and thumb size.
