rc-virtual-list

What is rc-virtual-list?

The rc-virtual-list npm package is a React component for efficiently rendering large lists and tabular data. It only renders the items that are currently visible in the viewport, which helps in improving the performance of the application by reducing the number of DOM nodes.

What are rc-virtual-list's main functionalities?

Basic Virtual List

This code sample demonstrates how to create a basic virtual list with fixed item height. The 'data' prop is an array of items to display, 'height' sets the height of the list, 'itemHeight' is the height of each item, and 'itemKey' is a unique key for each item.

import VirtualList from 'rc-virtual-list';

<VirtualList
  data={data}
  height={200}
  itemHeight={20}
  itemKey='id'
>{(item) => <div>{item.name}</div>}</VirtualList>

Dynamic Item Height

This code sample shows how to handle dynamic item heights. The 'style' parameter is used to apply necessary styles for positioning items in the virtual list.

import VirtualList from 'rc-virtual-list';

<VirtualList
  data={data}
  height={200}
  itemKey='id'
>{(item, index, style) => (
  <div style={style}>{item.name}</div>
)}</VirtualList>

Custom Scrollbar

This example illustrates how to integrate a custom scrollbar component into the virtual list. The 'components' prop allows you to replace the default scrollbar with a custom one.

import VirtualList from 'rc-virtual-list';
import CustomScrollbar from 'custom-scrollbar-component';

<VirtualList
  data={data}
  height={200}
  itemHeight={20}
  itemKey='id'
  components={{
    scrollbar: CustomScrollbar
  }}
>{(item) => <div>{item.name}</div>}</VirtualList>
