PrimeNG — Complete Angular UI Component Library

Introduction

PrimeNG is one of the most comprehensive UI component suites for Angular. Maintained by PrimeTek, it provides 80+ components covering data display, forms, overlays, menus, charts, and media, all with built-in accessibility and multiple theme options including Material Design and Bootstrap styles.

What PrimeNG Does

• Offers 80+ Angular components: DataTable, TreeTable, Calendar, Editor, Charts, and more
• Provides multiple built-in themes (Material, Bootstrap, Lara) with a visual theme designer
• Includes advanced DataTable features: virtual scrolling, row expansion, column reordering, and export
• Ships form components with validation integration for Angular Reactive and Template-driven forms
• Supports accessibility standards with ARIA attributes and keyboard navigation

Architecture Overview

PrimeNG components are standard Angular modules that use OnPush change detection for performance. Each component exposes inputs for configuration, outputs for events, and templates for custom content projection. The theming system uses CSS custom properties organized into design tokens, applied through a theme provider. PrimeFlex (optional utility CSS) and PrimeIcons complement the component library.

Self-Hosting & Configuration

• Install with npm install primeng primeicons
• Import individual component modules (e.g., TableModule) for tree-shaking
• Add a theme CSS import in angular.json styles array or use the theme provider API
• Configure global settings like locale and ripple effect via providePrimeNG() in app config
• Use standalone component imports for Angular 17+ simplified module setup

Key Features

• DataTable supports lazy loading, virtual scrolling, column resize, reorder, and CSV/PDF export
• Theme designer allows visual customization and generates downloadable theme files
• Form components integrate with Angular's FormControl and Validators out of the box
• Overlay components (Dialog, Sidebar, ConfirmDialog) support dynamic content and templates
• Chart component wraps Chart.js for bar, line, pie, doughnut, radar, and polar area charts
