Documentation

Installation

npm install preact-custom-scrollbars --save

or

yarn add preact-custom-scrollbars

This assumes that you’re using npm or yarn package manager with a module bundler like Webpack or Browserify to consume CommonJS modules.

If you don’t yet use npm or a modern module bundler, and would rather prefer a single-file UMD build that makes PreactCustomScrollbars available as a global object, you can grab a pre-built version from unpkg. We don’t recommend this approach for any serious application, as most of the libraries complementary to preact-custom-scrollbars are only available on npm.

Usage

This is the minimal configuration. Check out the Documentation for advanced usage.

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

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

The <Scrollbars> component is completely customizable. Check out the following code:

import { Scrollbars } from 'preact-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}>
    );
  }
}
