React Datasheet Grid for Next.js
Use this skill whenever a task involves react-datasheet-grid, spreadsheet-like grids, Excel/Airtable-like editing, custom grid columns, copy/paste, row operations, or Next.js integration problems around the package.
Default approach
- Detect the Next.js router. If the user does not specify, assume App Router.
- Install and import CSS once. Use
npm i react-datasheet-grid. In App Router import react-datasheet-grid/dist/style.css in app/layout.tsx; in Pages Router import it in pages/_app.tsx.
- Put the grid in a Client Component. In App Router, any component using DSG state, events, refs, or browser APIs must start with
'use client'.
- Prefer object rows +
keyColumn. Define a row type, keep value as Row[], and map object keys with keyColumn('field', builtInColumn).
- Choose grid component intentionally. Use
DataSheetGrid by default. Use DynamicDataSheetGrid only when object/function props such as columns, createRow, or duplicateRow need to change after the first render; memoize dynamic props with useMemo / useCallback.
- Cover editing semantics. For custom columns, always define
component, deleteValue, copyValue, pasteValue, and usually isCellEmpty. Use columnData for options.
- Check Next.js SSR pitfalls. Guard
document / window; use isoDateColumn when passing server-loaded date strings, or convert strings to Date objects before using dateColumn.
- Verify the full API checklist below before finalizing.
Must-not-miss API checklist
When implementing or reviewing, make sure no relevant piece is omitted:
- Grid components:
DataSheetGrid, DynamicDataSheetGrid.
- Built-in columns:
textColumn, checkboxColumn, intColumn, floatColumn, percentColumn, dateColumn, isoDateColumn.
- Column factories/helpers:
keyColumn, createTextColumn.
- Customizable component helpers:
createAddRowsComponent, createContextMenuComponent, renderContextMenuItem.
- Public types:
Column, CellComponent, CellProps, DataSheetGridProps, AddRowsComponentProps, SimpleColumn, ContextMenuComponentProps, ContextMenuItem, DataSheetGridRef.
- Grid props:
value, onChange, columns, gutterColumn, stickyRightColumn, height, rowHeight, headerRowHeight, lockRows, autoAddRow, disableContextMenu, disableExpandSelection, disableSmartDelete, className, style, rowClassName, cellClassName, rowKey, createRow, duplicateRow, addRowsComponent, contextMenuComponent, onFocus, onBlur, onActiveCellChange, onSelectionChange, onScroll.
- Column props:
title, id, basis, grow, shrink, minWidth, maxWidth, copyValue, pasteValue, prePasteValues, , , , , , , , , .
Reference files
Read these as needed:
- React Datasheet Grid API cheat sheet for exhaustive exports, props, column options, cell props, refs, and operations.
- Next.js integration guide for App Router, Pages Router, CSS, SSR, dates, and dynamic import guidance.
- Custom columns and recipes for custom cell components, select columns, i18n, row IDs, change tracking, collapsible rows, and infinite scroll.
Output standard
When producing code:
- Use TypeScript unless the project is clearly JavaScript-only.
- Include the CSS import location, not just the component code.
- Use
import type for DSG types when possible.
- Prefer
rowKey="id" and createRow / duplicateRow when rows can be inserted, deleted, or duplicated.
- Avoid accessing
document.body, window, or localStorage during render without a typeof guard.
- Do not import internal files from
react-datasheet-grid/dist/...; use the package root exports.
