World's most performant web table - Try it!
A multithreaded web table, capable of running 120fps while sorting/filtering/scrolling simultaneously.
Posting updates & soon video walk-through: https://x.com/GabrielPeterss4. DMs are open, curious to hear about use-cases or advise on how to use it :)
- Multithread sorting/filtering using a shared array buffer
- Display millions rows at O(1), you are only limited by browser RAM
- 120 fps while cruising the scrollbar
- Never drop a frame while filtering or sorting
The most performant DOM-based grid.
- Uses a shared array buffer to store order/filtering of rows, computed in a web worker off-thread
- Resuses all part of DOM-tree
- Own event loop to prioritize tasks. Never drops a frame, even when filtering millions of rows
- Non-passive scrolling. Rows will never be seen rows loading into the UI while scrolling
- Custom virtualization and scrolling. Not limited by browsers 15 million pixel div height limit
- Custom built scrolling for phones, and runs at 60fps even on older phones
| Benchmark | Score |
|---|---|
| Scroll 40 rows every frame | 120fps |
| Filtering | 200ms |
| Time to initialize grid and show rows | 1.5ms |
| Filter&sort simultaneously every 300ms | 120fps |
zero copy datatype
- iphone safari has a very low memory limit - disable multithreading there
- expand synthetic event-loop to include scrolling & rendering cell contents
- can maybe make GC be a bit less expensive by reusing cell classes more..
- if user zoomed in/out scrollbar will navigate to fast/slow, needs to be relative to the scroll track
- sort/filter all columns, not just second lol
- resize columns
- custom cells (you can kinda already do this though, just add a new cell class)
- make sure rows are ordered correctly for text selection
