Typescript

This library is written in Typescript and all types are exported directly.

Quick start

import {
  checkboxColumn,
  Column,
  DataSheetGrid,
  keyColumn,
  textColumn,
} from 'react-datasheet-grid'
import 'react-datasheet-grid/dist/style.css'

// Define your row type anywhere
type Row = {
  active: boolean
  firstName: string | null
  lastName: string | null
}

function App() {
  // Type your data (not DSG specific)
  const [data, setData] = useState<Row[]>([
    { active: true, firstName: 'Elon', lastName: 'Musk' },
    { active: false, firstName: 'Jeff', lastName: 'Bezos' },
  ])

  // Type your columns to get type checks in your IDE
  const columns: Column<Row>[] = [
    {
      ...keyColumn<Row, 'active'>('active', checkboxColumn),
      title: 'Active',
      width: 0.5,
    },
    {
      ...keyColumn<Row, 'firstName'>('firstName', textColumn),
      title: 'First name',
    },
    {
      ...keyColumn<Row, 'lastName'>('lastName', textColumn),
      title: 'Last name',
      width: 2,
    },
  ]

  return (
    <DataSheetGrid
      value={data}
      onChange={setData}
      columns={columns}
    />
  )
}

Generic props

Alternatively you can pass the row type to the component:

<DataSheetGrid<Row>
  value={data}
  onChange={setData}
  columns={columns}
/>
