react-window 2.4.0

on Node.js Yarn

Server rendering improvements:

Features

• Add defaultScrollOffset prop to List and defaultScrollLeft/defaultScrollTop props to Grid for setting the initial scroll position. Server-rendered HTML can't be pre-scrolled, so server rendering starts at the first row and the default scroll offset is applied when the component hydrates (unless the browser has already restored a scroll position). For lists and grids that are initially empty (e.g. while data is loading), the offset is applied once they have rows.
• Add initialRowHeights option to useDynamicRowHeight for providing row heights that are known or can be estimated ahead of time (e.g. during server rendering).
• Add a server rendering page to the docs site.

Bug fixes

• Server-rendered rows with dynamic heights are now displayed in normal document flow until they have been measured, rather than being positioned using estimated heights (which caused rows to overlap or leave gaps until after hydration).
• Fix List and Grid logging useLayoutEffect warnings when server rendered with React 18.
• Fix getScrollbarSize throwing when called during server rendering; it now returns 0.
