Something is not working as expected? Here is the list of hints that may help.
In order to work smoothly, library must know scrolled item sizes. Initially they equal
estimatedItemSize. But this is usually not
enough, because estimated and real sizes may differ.
ResizeObserver is used internally
for more accurate measurements, but you must provide mounted items explicitly in
conjunction with their indexes.
Not necessary. This website was build with tailwind, but you may use your styling approach.
itemcount value is
2_147_483_647 (int32 max).
This limit exists, because item sizes cache implementation has bitwise operations, which work only with int32.
But there is one more limit. W3C does not provide maximum allowed values for height, width, margin, etc.
CSS theoretically supports infinite precision and infinite ranges for all value types; however in reality implementations have finite capacity. UAs should support reasonably useful ranges and precisions
estimatedItemSize for fine-tuning.
Quantity of server-rendered items can be determined like this:
Math.min( itemCount, Math.ceil( estimatedWidgetSize / estimatedItemSize ) + overscanCount ).
