AG Grid — High-Performance JavaScript Data Grid

Introduction

AG Grid is a data grid library designed for enterprise-scale tabular data. Its Community edition is MIT-licensed and covers sorting, filtering, pagination, and cell rendering. The Enterprise edition adds row grouping, pivoting, charts, and server-side row models.

What AG Grid Does

• Renders large tabular datasets with virtual row and column rendering
• Provides client-side and server-side row models for different data scales
• Supports inline cell editing with custom editor components
• Offers column grouping, pinning, resizing, and drag-to-reorder
• Includes built-in CSV and Excel export functionality

Architecture Overview

AG Grid uses a virtual rendering engine that only creates DOM nodes for visible rows and columns. The grid core manages column state, row nodes, and cell value changes. Framework wrappers for React, Angular, and Vue translate grid events into framework-native patterns while the rendering engine handles scrolling and layout independently.

Self-Hosting & Configuration

• Install ag-grid-community for the free tier or ag-grid-enterprise for advanced features
• Add the framework wrapper package (ag-grid-react, ag-grid-angular, or ag-grid-vue3)
• Import a built-in theme CSS or create a custom theme with CSS variables
• Define columns with field, headerName, filter, and cellRenderer properties
• Use the grid API for programmatic control of selection, sorting, and data updates

Key Features

• Virtual scrolling handles millions of rows without DOM bloat
• 30+ built-in column filter types including set, number, date, and text
• Row grouping, tree data, and master-detail with expandable rows
• Clipboard support for copy-paste between the grid and spreadsheets
• Integrated charting with automatic data binding to grid selections

Comparison with Similar Tools

• TanStack Table — headless and lightweight, but requires building all UI from scratch
• MUI DataGrid — Material Design integration, React-only, smaller feature surface
• Handsontable — spreadsheet-oriented editing, commercial license
• SlickGrid — fast rendering but older codebase with fewer built-in features
• Tabulator — simpler API with built-in UI, less enterprise feature depth

FAQ

Q: Is AG Grid free? A: The Community edition is MIT-licensed and free. Enterprise features require a commercial license.

Q: How does it handle large datasets? A: Virtual row rendering only creates DOM for visible rows. Server-side row model loads data on demand.

Q: Which frameworks are supported? A: React, Angular, Vue 3, and vanilla JavaScript with dedicated wrapper packages.

Q: Can I customize cell rendering? A: Yes. Use cellRenderer to provide a custom component or function for any column.
