Material React Table Lagging in Chrome but Smooth in Firefox: Unraveling the Enigma

• Use `shouldComponentUpdate`: Implement the `shouldComponentUpdate` method to control when React re-renders your components, reducing unnecessary re-renders.
• Optimize `render` Methods: Ensure that your `render` methods are optimized for performance by minimizing computations and using memoization.
• Use React.memo: Wrap your components with `React.memo` to memoize their output and prevent unnecessary re-renders.

import React from 'react';

class MyTable extends React.Component {
  shouldComponentUpdate(nextProps, nextState) {
    // Only re-render when props or state change
    return nextProps.data !== this.props.data || nextState.sortOrder !== this.state.sortOrder;
  }

  render() {
    // Optimize render method using memoization
    const memoizedRows = memoize(() => this.props.data.map(row => (
      <TableRow key={row.id} {...row} />
    ));

    return (
      <table>
        {memoizedRows()}
      </table>
    );
  }
}

const memoize = (fn) => {
  let cache = {};
  return (...args) => {
    const key = JSON.stringify(args);
    if (!cache[key]) {
      cache[key] = fn(...args);
    }
    return cache[key];
  };
};

Solution 3: Leverage Web APIs

Web APIs like `requestAnimationFrame` and `IntersectionObserver` can help optimize your table’s performance in Chrome.

• Use `requestAnimationFrame`: Instead of using `setTimeout` or `setInterval`, use `requestAnimationFrame` to schedule animations and layouts, allowing the browser to optimize the rendering process.
• Implement Lazy Loading: Use `IntersectionObserver` to lazy load table rows, reducing the initial rendering load and improving performance.

import React, { useState, useEffect } from 'react';

const MyTable = () => {
  const [rows, setRows] = useState([]);
  const [scrollPosition, setScrollPosition] = useState(0);

  useEffect(() => {
    const handleScroll = () => {
      setScrollPosition(window.scrollY);
    };

    window.addEventListener('scroll', handleScroll);

    return () => {
      window.removeEventListener('scroll', handleScroll);
    };
  }, []);

  useEffect(() => {
    const lazyLoadRows = () => {
      if (scrollPosition + window.innerHeight >= rows.length * 50) {
        // Load more rows when user scrolls near the end of the table
        setRows([...rows, ...loadMoreRows()]);
      }
    };

    lazyLoadRows();
  }, [scrollPosition]);

  return (
    <table>
      {rows.map(row => (
        <TableRow key={row.id} {...row} />
      ))}
    </table>
  );
};
