A chat-aware Svelte viewport compared with a compact generic virtual list.
at a glance.
Compare @humanspeak/svelte-virtual-chat with svelte-tiny-virtual-list for Svelte 5 chat interfaces. Both virtualize long lists, but Svelte Virtual Chat includes streaming-safe follow-bottom, anchored history prepends, message identity, and automatic measurement for growing conversation content.
side-by-side.
Every surface that matters, compared without spin.
| feature | @humanspeak/svelte-virtual-chat | svelte-tiny-virtual-list |
|---|---|---|
| Svelte 5 support | yes | yes |
| Chat-aware follow-bottom | yes | no |
| Streaming height correction | Same-frame correction | no |
| History prepend anchoring | yes | no |
| Message identity | getMessageId | Array index |
| Automatic variable-height measurement | yes | no |
| Sticky indices | no | yes |
| Horizontal virtualization | no | yes |
| Programmatic scrolling | Message ID or bottom | Index |
where each shines.
- +Follow-bottom stays pinned while new messages and streaming tokens arrive
- +Scrolling away releases follow-bottom without new content pulling the reader back
- +Prepending older history preserves the visible message and its viewport offset
- +In-frame height correction keeps growing messages stable before paint
- +getMessageId tracks conversation identity instead of array position
- +Automatic variable-height measurement for rendered message content
- +Svelte 5 snippets, runes, TypeScript generics, and an imperative chat API
- +Chat behavior is part of the component contract instead of application wiring
- +Compact, dependency-free generic virtual-list component
- +Supports vertical and horizontal layouts
- +Supports sticky indices for pinned rows such as date separators
- +Accepts fixed, array-based, or function-based item sizes
where each falls short.
- −Purpose-built for vertical message timelines rather than generic lists, grids, or tables
- −Does not currently support sticky indices or document-window scrolling
- −Newer package with a smaller user community and ecosystem
- −Follow-bottom and scroll-away behavior must be implemented by the application
- −History prepends require application-level anchor capture and restoration
- −Growing streaming messages require manual measurement and scroll correction
- −Variable heights rely on supplied sizes or explicit recomputation
the honest call.
Choose svelte-tiny-virtual-list for a small generic Svelte 5 virtual list, especially when horizontal layouts or sticky indices matter. Choose @humanspeak/svelte-virtual-chat when the list is a conversation and stable streaming, follow-bottom, history loading, and message identity should work as one component contract.
