React window works by only rendering part of a large data set (just enough to fill the viewport). This helps address some common performance bottlenecks:

  1. It reduces the amount of work (and time) required to render the initial view and to process updates.
  2. It reduces the memory footprint by avoiding over-allocation of DOM nodes.

Frequently asked questions

How is react-window different from react-virtualized?

I wrote react-virtualized several years ago. At the time, I was new to both React and the concept of windowing. Because of this, I made a few API decisions that I later came to regret. One of these was adding too many non-essential features and components. Once you add something to an open source project, removing it is pretty painful for users.

react-window is a complete rewrite of react-virtualized. I didn't try to solve as many problems or support as many use cases. Instead I focused on making the package smaller1 and faster. I also put a lot of thought into making the API (and documentation) as beginner-friendly as possible (with the caveat that windowing is still kind of an advanced use case).

If react-window provides the functionality your project needs, I would strongly recommend using it instead of react-virtualized. However if you need features that only react-virtualized provides, you have two options:

  1. Use react-virtualized. (It's still widely used by a lot of successful projects!)
  2. Create a component that decorates one of the react-window primitives and adds the functionality you need. You may even want to release this component to NPM (as its own, standalone package)! 🙂

1 - Adding a react-virtualized list to a CRA project increases the (gzipped) build size by ~33.5 KB. Adding a react-window list to a CRA project increases the (gzipped) build size by <2 KB.

Can a list or a grid fill 100% the width or height of a page?

Yes. I recommend using the react-virtualized-auto-sizer package:

Why is my list blank when I scroll?

If your list looks something like this...

...then you probably forgot to use the style parameter! Libraries like react-window work by absolutely positioning the list items (via an inline style), so don't forget to attach it to the DOM element you render!

Can I lazy load data for my list?

Yes. I recommend using the react-window-infinite-loader package:
