Getting Started with PrimeNG: A UI Powerhouse for Angular Developers

#angular

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"
]
Enter fullscreen mode Exit fullscreen mode

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
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>
Enter fullscreen mode Exit fullscreen mode

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>
Enter fullscreen mode Exit fullscreen mode
