Getting Started with PrimeNG: A UI Powerhouse for Angular Developers

As frontend developers, we constantly search for tools that help us build beautiful, responsive, and interactive UIs — without reinventing the wheel. If you’re working with Angular and looking for a robust UI component library, PrimeNG is one of the top choices out there.

In this post, we’ll explore what PrimeNG is, why it’s worth considering, how to set it up, and how to use some of its most popular components.

What Is PrimeNG?

PrimeNG is a rich set of open-source UI components specifically designed for Angular. Developed by PrimeTek, it’s part of the larger Prime ecosystem that includes libraries for React (PrimeReact), Vue (PrimeVue), and more.

PrimeNG includes over 80 UI components — from basic elements like buttons and inputs to complex widgets like data tables, charts, calendars, carousels, and file uploaders.

Why Use PrimeNG?

Here are some reasons why PrimeNG stands out:

• Comprehensive Component Library
  Covers nearly every common UI need.
• Theming with PrimeFlex and Designer API
  Easily customize your app’s look and feel with a variety of themes and layout utilities.
• Accessibility (WCAG 2.0)
  Components follow accessibility best practices out of the box.
• Active Development and Community
  Regular updates, detailed documentation, and strong community support.
• Integration-Ready
  Compatible with Angular CLI and works smoothly with reactive forms, templating, and Angular animations.

How to Install PrimeNG

To get started, you need to install both PrimeNG and its required theme and icon libraries.

bashCopyEditnpm install primeng primeicons

Then, add the CSS files in your angular.json file:

jsonCopyEdit"styles": [
  "node_modules/primeng/resources/themes/lara-light-indigo/theme.css",
  "node_modules/primeng/resources/primeng.min.css",
  "node_modules/primeicons/primeicons.css"
]

You can also use other themes like lara-dark-indigo, saga-blue, vela-green, etc.

Using PrimeNG Components

Once set up, you can import and use components as needed.

Example: Button

tsCopyEditimport { ButtonModule } from 'primeng/button';

In your template:

htmlCopyEdit<p-button label="Click Me"></p-button>

Example: DataTable

tsCopyEditimport { TableModule } from 'primeng/table';

Template:

htmlCopyEdit<p-table [value]="products">
  <ng-template pTemplate="header">
    <tr>
      <th>Name</th>
      <th>Price</th>
    </tr>
  </ng-template>
  <ng-template pTemplate="body" let-product>
    <tr>
      <td>{{ product.name }}</td>
      <td>{{ product.price | currency }}</td>
    </tr>
  </ng-template>
</p-table>

Theming and Layout

PrimeNG uses PrimeFlex, a CSS utility library similar to Tailwind CSS. You can control spacing, layout, display, alignment, and more without writing custom CSS.

htmlCopyEdit<div class="p-d-flex p-jc-center p-ai-center p-mt-4">
  <p-button label="Submit"></p-button>
</div>
