r/reactjs on Reddit: Using react-window - is this good and performant code?

February 13, 2025 -

I am building an application that displays a very long list of data - think a Spotify-style playlist with 10,000+ rows, each with several columns and unique thumbnail images.

I've come across react-window to improve performance, as this only renders the rows in view rather than all 10k.

However, by default it doesn't support sticky rows, and what I want is a header, a sticky row, and then my list rows, all within a single scrolling container.

I started from their official demo, here.

I've now modified this to get it working the way I want.

But there's an awful lot of re-renders happening, and I'm not confident my code is performant.

Can this codesandbox be improved upon for better performance? And is this good code in general?

https://codesandbox.io/p/sandbox/react-window-with-sticky-headers-chp6dx

I've created a generic StickyList component, and my more specific MyList component that passes the content down to it.

Many thanks for any help!

EDIT:

Following advice in the comments, I've rewritten the demo using Tanstack Virtual. It seems clearer and easier to control and manage!

https://codesandbox.io/p/devbox/suspicious-wildflower-4prdcj?workspaceId=ws_4XrM7ka75TBJaLftpJJK6R

You'd better use @tanstack/virtual, it's far better and up to date and supports sticky headers.

Yeah, react-window is a bit old nowadays. I recommend https://virtuoso.dev/ though, it's pretty much "batteries included" and it also lets you customize it.

Open a component in new window on a click in react

You can use ReactDOM.createPortal to render a component in a new window as David Gilbertson explains in his post:

class MyWindowPortal extends React.PureComponent {
  constructor(props) {
    super(props);
    // STEP 1: create a container <div>
    this.containerEl = document.createElement('div');
    this.externalWindow = null;
  }
  
  render() {
    // STEP 2: append props.children to the container <div> that isn't mounted anywhere yet
    return ReactDOM.createPortal(this.props.children, this.containerEl);
  }

  componentDidMount() {
    // STEP 3: open a new browser window and store a reference to it
    this.externalWindow = window.open('', '', 'width=600,height=400,left=200,top=200');

    // STEP 4: append the container <div> (that has props.children appended to it) to the body of the new window
    this.externalWindow.document.body.appendChild(this.containerEl);
  }

  componentWillUnmount() {
    // STEP 5: This will fire when this.state.showWindowPortal in the parent component becomes false
    // So we tidy up by closing the window
    this.externalWindow.close();
  }
}

The upvoted answer works great!

Just leaving a function component version here in case people are searching for that in the future.

const RenderInWindow = (props) => {
  const [container, setContainer] = useState(null);
  const newWindow = useRef(null);

  useEffect(() => {
    // Create container element on client-side
    setContainer(document.createElement("div"));
  }, []);

  useEffect(() => {
    // When container is ready
    if (container) {
      // Create window
      newWindow.current = window.open(
        "",
        "",
        "width=600,height=400,left=200,top=200"
      );
      // Append container
      newWindow.current.document.body.appendChild(container);

      // Save reference to window for cleanup
      const curWindow = newWindow.current;

      // Return cleanup function
      return () => curWindow.close();
    }
  }, [container]);

  return container && createPortal(props.children, container);
};

reactjs - How to get the reference for new window object from a Component which opens the window? - Stack Overflow

I was trying to do something similar but wanted the popup window to print when it opened.

Here's the solution (using React hooks):

import React, {useEffect, useRef} from 'react';
import NewWindow from "react-new-window";

const PopupWindow = () => {
    const thisWindow = useRef(null);

    // This will fire when thisWindow reference changes.
    useEffect(() => {
        thisWindow.current.window.focus();
        // thisWindow.current.window.print();  // To print when the popup window loads.
    }, [thisWindow]);

    return (
        <>
            <NewWindow
                ref={thisWindow}
            >
                <p>
                   Your content here
                </p>
            </NewWindow>
        </>
    )
}

export default PopupWindow;

We can access window object created in the component by using const chartWindow = useRef(null) on the component and access like this way, chartWindow.current.window.focus()

r/reactjs on Reddit: react-window v2.0 is out 🥳

August 28, 2025 -

Just a quick note that version 2 has been published.

Docs and examples can be found at https://react-window.vercel.app/

High level overview of what changed and why you might want to upgrade is in the change log but I'll save you a click:

More ergonomic props API
Automatic memoization of row/cell renderers and props/context
Automatically sizing for List and Grid (no more need for AutoSizer)
Native TypeScript support (no more need for u/types/react-window)
Smaller bundle size

I appreciate the feedback that was shared during the alpha phase. If anyone has troubles with v2, please tag me here or on GitHub and I'll be happy to take a look.

Thanks!

I just want to say a big "thank you" for this library! I use it in the open source serial terminal NinjaTerm that I develop. It plays a vital role in keeping the app performant when there are 1000s of rows of text. I found it easy to setup and use, great stuff!
