Memoization Development Tutorials, Guides & Insights

For very large lists, consider using windowing libraries like react-window to only render a subset of the list items that are currently visible.

import React from 'react';
import { FixedSizeList as List } from 'react-window';

const Row = ({ index, style }) => (
  <div style={style}>Row {index}</div>
);

function MyList({ itemCount }) {
  return (
    <List
      height={400}
      itemCount={itemCount}
      itemSize={35}
      width={300}
    >
      {Row}
    </List>
  );
}

export default MyList;
