react-window 2.1.0

on Node.js NPM

Improved ARIA support:

• Add better default ARIA attributes for outer HTMLDivElement
• Add optional ariaAttributes prop to row and cell renderers to simplify better ARIA attributes for user-rendered cells
• Remove intermediate HTMLDivElement from List and Grid
  • This may enable more/better custom CSS styling
  • This may also enable adding an optional children prop to List and Grid for e.g. overlays/tooltips
• Add optional tagName prop; defaults to "div" but can be changed to e.g. "ul"

// Example of how to use new `ariaAttributes` prop
function RowComponent({
  ariaAttributes,
  index,
  style,
  ...rest
}: RowComponentProps<object>) {
  return (
    <div style={style} {...ariaAttributes}>
      ...
    </div>
  );
}

Added optional children prop to better support edge cases like sticky rows.

Minor changes to onRowsRendered and onCellsRendered callbacks to make it easier to differentiate between visible items and items rendered due to overscan settings. These methods will now receive two params– the first for visible rows and the second for all rows (including overscan), e.g.:

function onRowsRendered(
  visibleRows: {
    startIndex: number;
    stopIndex: number;
  },
  allRows: {
    startIndex: number;
    stopIndex: number;
  }
): void {
  // ...
}

function onCellsRendered(
  visibleCells: {
    columnStartIndex: number;
    columnStopIndex: number;
    rowStartIndex: number;
    rowStopIndex: number;
  },
  allCells: {
    columnStartIndex: number;
    columnStopIndex: number;
    rowStartIndex: number;
    rowStopIndex: number;
  }
): void {
  // ...
}
