Enable better typescript support #27
Description
Currently the items do not use generics to keep the typings available. e.g.
<script lang="ts"> let data = [ { id: 123, text: "item text" } ] </script> <VirtualScroll {data} let:data> <div> <!-- data is "any", no typings info --> {data.text} </div> </VirtualScroll> My proposal is to configure tighter typings for data, slot data and key:
data: T[] key: keyof T slot data: T
