PulseGrid
Headless data table with sorting and virtual scroll that stays smooth at a hundred thousand rows.
// why pulsegrid
A hundred thousand rows
Virtualisation is measured, not guessed. Row heights can vary and the scrollbar still lands exactly where the user expects.

Bring your own markup
PulseGrid computes what should be visible. Rendering is entirely yours, so the table matches the rest of your product.
PulseGrid started as a single file in a client project and stayed small on purpose. It does one job, it does it in 11kb gzipped, and it has no runtime dependencies.
Getting started
Install it, import it, call it:
npm i pulsegrid-jsVirtualisation is measured, not guessed. Row heights can vary and the scrollbar still lands exactly where the user expects.
What it does not do
It does not manage your state, style your components or ship a plugin system. Those are your decisions, and keeping them out is what keeps the bundle honest.
- Variable row heights
- Full keyboard grid
- MIT licensed, commercially friendly
Features
Variable row heights
Measured on the fly and cached, so mixed content does not break scroll position.
Full keyboard grid
Arrow keys, Home, End, Page Up and Page Down all behave the way a spreadsheet user expects.
Container aware
Adapts to the box it is given rather than the viewport, so it works in a sidebar.
Accessibility audited
Tested against screen readers on three platforms, with the findings published in the repository.
ESM and types
Ships module and CommonJS builds with hand-written type definitions and source maps.
Styling stays yours
PulseGrid sets no colours and no spacing. Every visual decision belongs to your design system.
