Neo.mjs v10.4.1 Release Notes

Highlights

This patch release polishes the "instant preview" feature for grids introduced in v10.4.0, ensuring the grid's scrollbar and accessibility properties are correctly sized from the very first paint when loading large datasets. The non-buffered table.Body also receives a major performance boost for clearing data.

Enhancements & Bug Fixes

1. Polished "Instant Preview" for Large Datasets in Grids

The chunked loading mechanism for stores and grids has been refined. When adding a large dataset, the initial load event now carries the final total record count. The grid.Container uses this information immediately to set the correct aria-rowcount and to size the vertical scrollbar accurately, preventing layout shifts and providing a more stable and accessible user experience from the very first render.

2. Standardized Internal Store load Event

To support the "instant preview" refinements, the data.Store load event payload has been standardized internally. It now consistently uses an object containing an items property (e.g., {items: [...]}). Framework components have been updated to use this new signature.

3. Performance Fast Path for table.Body

The non-buffered table.Body is now significantly faster when clearing its data. It uses the same "fast path" optimization as grid.Body, directly clearing the DOM instead of processing a large and unnecessary VDOM diff when an empty dataset is loaded. This aligns the performance of the two components.
