react-window-dynamic

This is a fork of react-window providing the npm package with issues/6 branch that added support for DynamicSizeList

Why?

It wasn't working using git dependency on our CI because our env was failing on the prepare script (which is running when installing git dependencies), so we have published it as an npm package.

  • react-virtualized-auto-sizer: HOC that grows to fit all of the available space and passes the width and height values to its child.
  • react-window-infinite-loader: Helps break large data sets down into chunks that can be just-in-time loaded as they are scrolled into view. It can also be used to create infinite loading lists (e.g. Facebook or Twitter).

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:

Yes, using the outerElementType prop.

Can I add gutter or padding between items?

Yes, although it requires a bit of inline styling.

Does this library support "sticky" items?

Yes, although it requires a small amount of user code. Here are Code Sandbox demos for list and grids:
