React

@ezygrid/react ships a thin, uncontrolled <Spreadsheet> component (peer dependencies: react and react-dom >= 18).

Install

pnpm add @ezygrid/react @ezygrid/core @ezygrid/theme-default

Usage

import { Spreadsheet } from '@ezygrid/react';
import '@ezygrid/theme-default/index.css';

export function Budget() {
  return (
    <Spreadsheet
      worksheets={[{ name: 'Budget', rows: 200, columns: 10, data: [['A', 'B'], [1, '=B1*2']] }]}
      renderer={{ formulaBar: true, toolbar: true }}
      style={{ height: 480 }}
      onReady={(workbook, renderer) => console.log('ready', workbook, renderer)}
    />
  );
}

Props

SpreadsheetProps flattens workbook options at the top level plus:

Prop	Type	Description
worksheets, id, extensions	CreateGridOptions	Workbook options
renderer	GridRendererOptions	Presentation options
onReady	(workbook: Workbook, renderer: GridRenderer) => void	Called once mounted
className	string	Host container class
style	CSSProperties	Host container styles (give it a height)

Uncontrolled by design

The workbook model owns state. Parent re-renders never repaint the grid; the component mounts once and hands you the workbook handle. Mutate data through the model, not props:

const ref = useRef<Workbook>();

<Spreadsheet onReady={(workbook) => { ref.current = workbook; }} />

// elsewhere
ref.current?.activeWorksheet.setValue(0, 0, 'Hello');

SSR

The component is SSR-safe: nothing touches the DOM until mounted on the client.
