Integrate PrimeNG Components: A Quick Guide for Angular Apps

Want to build stunning user interfaces in your Angular applications without the hassle of writing everything from scratch? Discover how to use PrimeNG components for a streamlined development experience.

This guide provides a step-by-step approach to integrating and using PrimeNG, a comprehensive UI component library, within your Angular projects. You'll learn how to set up your project, import the necessary modules, and implement some components.

What Is PrimeNG and Why Use It in Angular?

PrimeNG is a rich set of open-source UI components for Angular, created by PrimeFaces. Think of it as a toolbox packed with pre-built elements like buttons, forms, data tables, and more, all designed to make your app development faster and more efficient.

Here’s why developers choose PrimeNG:

• Ready-to-use components: Save time and effort with a vast library of pre-designed UI elements.
• Customizable themes: Easily tailor the look and feel of your application to match your brand.
• Responsive design: Ensure your application looks great on any device.
• Accessibility: Create inclusive experiences with components that meet accessibility standards.

Preparing Your Angular Environment for PrimeNG

Before diving into PrimeNG, let’s ensure your Angular project is ready:

1. Install Node.js: If you haven't already, download and install Node.js to manage your project dependencies.
2. Install Angular CLI: Open your terminal and run npm install -g @angular/cli to install the command-line interface for Angular.

Creating a New Angular Project

Use the Angular CLI to scaffold a new project. Run the following command in your terminal:

ng new AngularPrimeNGExample --style=css --routing=false --skip-tests
cd AngularPrimeNGExample

This command sets up a basic Angular project, configured to use CSS for styling and without routing or testing modules.

Installing PrimeNG and PrimeIcons

Install PrimeNG and its icon library using npm (Node Package Manager):

npm install [email protected] [email protected]

This adds the necessary PrimeNG and PrimeIcons packages to your project's node_modules directory and updates your package.json file.

Adding PrimeNG Styles to Your Angular App

To make PrimeNG components visually appealing, add the required CSS files to your project.

Open the angular.json file and update the "styles" array:

"styles": [
  "styles.css",
  "node_modules/font-awesome/css/font-awesome.min.css",
  "node_modules/primeng/resources/primeng.min.css",
  "node_modules/primeng/resources/themes/saga-blue/theme.css"
],

Remember to restart your local server after modifying angular.json to apply the changes.

Importing PrimeNG Modules: Using PrimeNG Components

To effectively use PrimeNG components, import the specific modules you need into your app.module.ts file.

Import the necessary modules, such as AccordionModule, PanelModule, ButtonModule, and RadioButtonModule:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { FormsModule } from '@angular/forms';

import { AccordionModule } from 'primeng/accordion';
import { PanelModule } from 'primeng/panel';
import { ButtonModule } from 'primeng/button';
import { RadioButtonModule } from 'primeng/radiobutton';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    FormsModule,
    AccordionModule,
    PanelModule,
    ButtonModule,
    RadioButtonModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Do not forget to import Angular's BrowserAnimationsModule and FormsModule as they are required for component animations and form inputs, respectively.

Building a Simple UI with PrimeNG

Now, let’s put those PrimeNG modules into action. Let’s build a pizza ordering interface using accordion, panel, radio button, and button components.

Preparing Component Logic

First, update src/app/app.component.ts to include a property for pizza selection:

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  pizzaSelection = '';
}

Implementing the UI

Edit the src/app/app.component.html file to define the UI structure using the imported PrimeNG components.

<p-accordion>
    <p-accordionTab header="Menu">
        <p-panel header="Salads">
            Content of first panel
        </p-panel>
        <p-panel header="Pasta">
            Content of second panel
        </p-panel>
        <p-panel header="Pizza">
            <p-radioButton name="pizza" value="Pepperoni" label="Pepperoni" [(ngModel)]="pizzaSelection"></p-radioButton>
            <p-radioButton name="pizza" value="Vegetarian" label="Vegetarian" [(ngModel)]="pizzaSelection"></p-radioButton>
            <p-radioButton name="pizza" value="Margherita" label="Margherita" [(ngModel)]="pizzaSelection"></p-radioButton>
        </p-panel>
    </p-accordionTab>
    <p-accordionTab header="Extras" [disabled]="!pizzaSelection">
        <p-panel header="Add-ons">
            <p>Would you like extra cheese on your pizza?</p>
            <p-button label="Add Cheese"></p-button>
        </p-panel>
    </p-accordionTab>
</p-accordion>

Notice how the components use the p- prefix.
