@better-grid/core

Framework-agnostic, TypeScript-first data grid & spreadsheet engine. The pure rendering + state machine that powers Better Grid.

• Virtualized rendering with DOM cell pooling (~200 elements regardless of dataset size)
• Fake-scrollbar architecture, multi-level headers, frozen rows/columns, separate pinned-row overlay
• Range / multi-range / fill-handle selection, full keyboard navigation
• cellType registry, custom cellRenderer API, CSS variables for theming
• Composable plugin architecture (createGrid({ plugins: [...] }))

npm install @better-grid/core

import { createGrid } from '@better-grid/core';
import '@better-grid/core/styles.css';

const grid = createGrid({
  columns: [{ id: 'name', field: 'name', headerName: 'Name', width: 200 }],
  data: [{ name: 'Alice' }],
});
grid.mount(document.getElementById('grid')!);

For most React apps you want @better-grid/react and @better-grid/plugins on top.
