React Recycled Scrolling

Simulate normal scrolling by using only fixed number of DOM elements for large lists of items with React Hooks

Install

npm install --save react-recycled-scrolling

Usage

All that is required is

• attrList: A list of items
• itemFn: A React functional component or even just a function that returns jsx for each element

const numberList = []
for (let i = 1; i <= 20000; i++) numberList.push(i)
const SheepRow = (no) => (<div> {no} Sheep </div>)

Then just drop in your RecycledList wherever you need it

import RecycledList from 'react-recycled-scrolling'

<RecycledList
itemFn = {SheepRow}
attrList = {numberList}
/>

Additional parameters are

• itemHeight: Height of each item, Default: 50
• rowOffset: How many buffer rows you need outside the viewable screen, Default: 6
• className: custom CSS for the outer scroll wrapper. You must have {position: relative} for recycled scroll to work

<RecycledList
  itemFn = {SheepRow}
  attrList = {numberList}
  itemHeight = {120}
  rowOffset = {10}
  className = {'CustomContainer'}
/>
