A high-performance React data grid component with virtual scrolling, cell selection, sorting, filtering, and Excel-like editing

@gp-grid/react 🏁 🏎️

A high-performance, feature lean React data grid component built to manage grids with huge amount (millions) of rows. It's based on its core dependency: @gp-grid/core, featuring virtual scrolling, cell selection, sorting, filtering, editing, and Excel-like fill handle.

Features

Virtual Scrolling: Efficiently handles millions of rows through slot-based recycling
Cell Selection: Single cell, range selection, Shift+click extend, Ctrl+click toggle
Multi-Column Sorting: Click to sort, Shift+click for multi-column sort
Column Filtering: Built-in filter row with debounced input
Cell Editing: Double-click or press Enter to edit, with custom editor support
Fill Handle: Excel-like drag-to-fill for editable cells
Keyboard Navigation: Arrow keys, Tab, Enter, Escape, Ctrl+A, Ctrl+C
Custom Renderers: Registry-based cell, edit, and header renderers
Dark Mode: Built-in dark theme support
TypeScript: Full type safety with exported types

Installation

Use npm, yarn or pnpm

pnpm add @gp-grid/react

Quick Start

import { Grid, type ColumnDefinition } from "@gp-grid/react";

interface Person {
  id: number;
  name: string;
  age: number;
  email: string;
}

const columns: ColumnDefinition[] = [
  { field: "id", cellDataType: "number", width: 80, headerName: "ID" },
  { field: "name", cellDataType: "text", width: 150, headerName: "Name" },
  { field: "age", cellDataType: "number", width: 80, headerName: "Age" },
  { field: "email", cellDataType: "text", width: 250, headerName: "Email" },
];

const data: Person[] = [
  { id: 1, name: "Alice", age: 30, email: "[email protected]" },
  { id: 2, name: "Bob", age: 25, email: "[email protected]" },
  { id: 3, name: "Charlie", age: 35, email: "[email protected]" },
];

function App() {
  return (
    <div style={{ width: "800px", height: "400px" }}>
      <Grid columns={columns} rowData={data} rowHeight={36} />
    </div>
  );
}

Examples

Client-Side Data Source with Sorting and Filtering

For larger datasets with client-side sort/filter operations:

import { useMemo } from "react";
import {
  Grid,
  createClientDataSource,
  type ColumnDefinition,
} from "@gp-grid/react";

interface Product {
  id: number;
  name: string;
  price: number;
  category: string;
}

const columns: ColumnDefinition[] = [
  { field: "id", cellDataType: "number", width: 80, headerName: "ID" },
  { field: "name", cellDataType: "text", width: 200, headerName: "Product" },
  { field: "price", cellDataType: "number", width: 100, headerName: "Price" },
  {
    field: "category",
    cellDataType: "text",
    width: 150,
    headerName: "Category",
  },
];

function ProductGrid() {
  const products: Product[] = useMemo(
    () =>
      Array.from({ length: 10000 }, (_, i) => ({
        id: i + 1,
        name: `Product ${i + 1}`,
        price: Math.round(Math.random() * 1000) / 10,
        category: ["Electronics", "Clothing", "Food", "Books"][i % 4],
      })),
    [],
  );

  const dataSource = useMemo(
    () => createClientDataSource(products),
    [products],
  );

  return (
    <div style={{ width: "100%", height: "500px" }}>
      <Grid
        columns={columns}
        dataSource={dataSource}
        rowHeight={36}
        headerHeight={40}
        showFilters={true}
        filterDebounce={300}
      />
    </div>
  );
}

Server-Side Data Source

For datasets too large to load entirely in memory, use a server-side data source:

import { useMemo } from "react";
import {
  Grid,
  createServerDataSource,
  type ColumnDefinition,
  type DataSourceRequest,
  type DataSourceResponse,
} from "@gp-grid/react";

interface User {
  id: number;
  name: string;
  email: string;
  role: string;
  createdAt: string;
}

const columns: ColumnDefinition[] = [
  { field: "id", cellDataType: "number", width: 80, headerName: "ID" },
  { field: "name", cellDataType: "text", width: 150, headerName: "Name" },
  { field: "email", cellDataType: "text", width: 250, headerName: "Email" },
  { field: "role", cellDataType: "text", width: 120, headerName: "Role" },
  {
    field: "createdAt",
    cellDataType: "dateString",
    width: 150,
    headerName: "Created",
  },
];

// API fetch function that handles pagination, sorting, and filtering
async function fetchUsers(
  request: DataSourceRequest,
): Promise<DataSourceResponse<User>> {
  const { pagination, sort, filter } = request;

  // Build query parameters
  const params = new URLSearchParams({
    page: String(pagination.pageIndex),
    limit: String(pagination.pageSize),
  });

  // Add sorting parameters
  if (sort && sort.length > 0) {
    // Format: sortBy=name:asc,email:desc
    const sortString = sort.map((s) => `${s.colId}:${s.direction}`).join(",");
    params.set("sortBy", sortString);
  }

  // Add filter parameters
  if (filter) {
    Object.entries(filter).forEach(([field, value]) => {
      if (value) {
        params.set(`filter[${field}]`, value);
      }
    });
  }

  // Make API request
  const response = await fetch(`https://api.example.com/users?${params}`);

  if (!response.ok) {
    throw new Error(`API error: ${response.status}`);
  }

  const data = await response.json();

  // Return in DataSourceResponse format
  return {
    rows: data.users, // Array of User objects
    totalRows: data.total, // Total count for virtual scrolling
  };
}

function UserGrid() {
  // Create server data source - memoize to prevent recreation
  const dataSource = useMemo(
    () => createServerDataSource<User>(fetchUsers),
    [],
  );

  return (
    <div style={{ width: "100%", height: "600px" }}>
      <Grid
        columns={columns}
        dataSource={dataSource}
        rowHeight={36}
        headerHeight={40}
        showFilters={true}
        filterDebounce={500} // Debounce filter requests
        darkMode={true}
      />
    </div>
  );
}

Custom Cell Renderers

Use the registry pattern to define reusable renderers:

import {
  Grid,
  type ColumnDefinition,
  type CellRendererParams,
} from "@gp-grid/react";

interface Order {
  id: number;
  customer: string;
  total: number;
  status: "pending" | "shipped" | "delivered" | "cancelled";
}

// Define reusable renderers
const cellRenderers = {
  // Currency formatter
  currency: (params: CellRendererParams) => {
    const value = params.value as number;
    return (
      <span style={{ color: "#047857", fontWeight: 600 }}>
        ${value.toLocaleString("en-US", { minimumFractionDigits: 2 })}
      </span>
    );
  },

  // Status badge
  statusBadge: (params: CellRendererParams) => {
    const status = params.value as Order["status"];
    const colors: Record<string, { bg: string; text: string }> = {
      pending: { bg: "#fef3c7", text: "#92400e" },
      shipped: { bg: "#dbeafe", text: "#1e40af" },
      delivered: { bg: "#dcfce7", text: "#166534" },
      cancelled: { bg: "#fee2e2", text: "#991b1b" },
    };
    const color = colors[status] ?? { bg: "#f3f4f6", text: "#374151" };

    return (
      <span
        style={{
          backgroundColor: color.bg,
          color: color.text,
          padding: "2px 8px",
          borderRadius: "12px",
          fontSize: "12px",
          fontWeight: 600,
        }}
      >
        {status.toUpperCase()}
      </span>
    );
  },

  // Bold text
  bold: (params: CellRendererParams) => (
    <strong>{String(params.value ?? "")}</strong>
  ),
};

const columns: ColumnDefinition[] = [
  {
    field: "id",
    cellDataType: "number",
    width: 80,
    headerName: "ID",
    cellRenderer: "bold",
  },
  {
    field: "customer",
    cellDataType: "text",
    width: 200,
    headerName: "Customer",
  },
  {
    field: "total",
    cellDataType: "number",
    width: 120,
    headerName: "Total",
    cellRenderer: "currency",
  },
  {
    field: "status",
    cellDataType: "text",
    width: 120,
    headerName: "Status",
    cellRenderer: "statusBadge",
  },
];

function OrderGrid({ orders }: { orders: Order[] }) {
  return (
    <div style={{ width: "100%", height: "400px" }}>
      <Grid
        columns={columns}
        rowData={orders}
        rowHeight={40}
        cellRenderers={cellRenderers}
      />
    </div>
  );
}

Editable Cells with Custom Editors

import { useState } from "react";
import {
  Grid,
  createClientDataSource,
  type ColumnDefinition,
  type EditRendererParams,
} from "@gp-grid/react";

interface Task {
  id: number;
  title: string;
  priority: "low" | "medium" | "high";
  completed: boolean;
}

// Custom select editor for priority field
const editRenderers = {
  prioritySelect: (params: EditRendererParams) => {
    const [value, setValue] = useState(params.initialValue as string);

    return (
      <select
        autoFocus
        value={value}
        onChange={(e) => {
          setValue(e.target.value);
          params.onValueChange(e.target.value);
        }}
        onBlur={() => params.onCommit()}
        onKeyDown={(e) => {
          if (e.key === "Enter") params.onCommit();
          if (e.key === "Escape") params.onCancel();
        }}
        style={{

      autoFocus
      defaultChecked={params.initialValue as boolean}
      onChange={(e) => {
        params.onValueChange(e.target.checked);
        params.onCommit();
      }}
      style={{ width: 20, height: 20 }}
    />
  ),
};

const columns: ColumnDefinition[] = [

    cellDataType: "boolean",
    width: 100,
    headerName: "Done",
    editable: true,
    editRenderer: "checkbox", // Custom editor
  },
];

function TaskGrid() {
  const tasks: Task[] = [
    { id: 1, title: "Write documentation", priority: "high", completed: false },
    { id: 2, title: "Fix bugs", priority: "medium", completed: true },
    { id: 3, title: "Add tests", priority: "low", completed: false },
  ];

  const dataSource = createClientDataSource(tasks);

Styling

The grid injects its own styles automatically. The main container uses these CSS classes:

.gp-grid-container - Main container
.gp-grid-container--dark - Dark mode modifier
.gp-grid-header - Header row container
.gp-grid-header-cell - Individual header cell
.gp-grid-row - Row container
.gp-grid-cell - Cell container
.gp-grid-cell--active - Active cell
.gp-grid-cell--selected - Selected cell
.gp-grid-cell--editing - Cell in edit mode
.gp-grid-filter-row - Filter row container
.gp-grid-filter-input - Filter input field
.gp-grid-fill-handle - Fill handle element
