Getting Started With PrimeNG Styling in Angular App

 This chapter we are going to check how you can add PrimeNG card component to show available flowers in the stock. Before styling the app, I have added some images of flowers to our assets folder as below.

In app.module.ts file you can import PrimeNG Card module as below.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { LandingComponent } from './modules/landing/landing.component';
import { HomeComponent } from './modules/home/home.component';
import { CardModule } from 'primeng/card';
;

@NgModule({
  declarations: [
    AppComponent,
    LandingComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    CardModule,
    
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

import { Component, OnInit } from '@angular/core';
import { flower } from '../../domain/flower';
import {CardModule} from 'primeng/card';

@Component({
  selector: 'app-landing',
  templateUrl: './landing.component.html',
  styleUrls: ['./landing.component.scss']
})
export class LandingComponent implements OnInit {

  myFlowerList:flower[]=[];
  constructor() { }
  ngOnInit() {
    this.mySellingFlowers();
  }

  mySellingFlowers(){
    let rose = new flower();
    rose.name = "Rose";
    rose.price = 100;
    rose.availableQuantity = 1000;
    this. myFlowerList.push(rose);

    let lily = new flower();
    lily.name = "Lilly";
    lily.price = 80;
    lily.availableQuantity = 2000;
    this. myFlowerList.push(lily);

    let tulip = new flower();
    tulip.name = "Tulip";
    tulip.price = 100;
    tulip.availableQuantity = 2300;
    this. myFlowerList.push(tulip);

    let carnation = new flower();
    carnation.name = "Carnation";
    carnation.price = 50;
    carnation.availableQuantity = 1500;
    this. myFlowerList.push(carnation);

    let gerbera = new flower();
    gerbera.name = "Gerbera";
    gerbera.price = 50;
    gerbera.availableQuantity = 1500;
    this. myFlowerList.push(gerbera);

    let orchid = new flower();
    orchid.name = "Orchid";
    orchid.price = 50;
    orchid.availableQuantity = 1500;
    this. myFlowerList.push(orchid);
  }
}

   trackFlowers(index,flower){
    	return flower?flower.name:undefined
  	}
  }

Then you can use PrimeNG card module inside your component.html file as below.

<h1>Welcome to my flower store</h1>
<div *ngFor="let flower of myFlowerList;trackBy:trackFlowers">
        <p-card header="{{flower.name}}"  [style]="{width: '360px','float':'left','margin-bottom': '2em','margin-right': '2em','background-color':'light-pink'}" styleClass="p-card-shadow">
                <img alt="Card" width="100" height="100" src="assets/stock/{{flower.name}}.jpg">
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Inventore sed consequuntur error repudiandae numquam deserunt
                quisquam repellat libero asperiores earum nam nobis, culpa ratione quam perferendis esse, cupiditate neque quas!</p>
                   </p-card>
    </div>

I have changed background styles in the banner in style.scss file.  

@import url('https://fonts.googleapis.com/css family=Nunito:400,700&display=swap');

$primary: indianred;

body {
    margin: 0;
    font-family: 'Nunito', 'sans-serif';
    font-size: 18px;
}

.container {
    width: 80%;
    margin: 0 auto;
}

header {
    background: $primary;
    padding: 1em 0;

    a {
        color: white;
        text-decoration: none;
        font-size: larger;
    }
    a.logo {
        font-weight: bold;
        color: white;
        font-size: larger;
    }

    nav {
        float: right;

        ul {
            list-style-type: none;
            margin: 0;
            display: flex;

            li a {
                padding: 1em;
                color:white;
                font-weight: bold;
                &:hover {
                    background: darken($primary, 10%);
                }
            }
        }
    }
}

h1 {
    margin-top: 2em;
}

Once you apply PrimeNG cards modules, app will look like below.

.ui-card-title{
    background-color: lightpink !important;
}

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { flower } from '../../domain/flower';
import {CardModule} from 'primeng/card';

@Component({
  selector: 'app-landing',
  templateUrl: './landing.component.html',
  styleUrls: ['./landing.component.scss'],
  encapsulation: ViewEncapsulation.None
})
export class LandingComponent implements OnInit {

  myFlowerList:flower[]=[];
  constructor() { }

  ngOnInit() {
    this.mySellingFlowers();
  }

  mySellingFlowers(){
    let rose = new flower();
    rose.name = "Rose";
    rose.price = 100;
    rose.availableQuantity = 1000;
    this. myFlowerList.push(rose);

    let lily = new flower();
    lily.name = "Lilly";
    lily.price = 80;
    lily.availableQuantity = 2000;
    this. myFlowerList.push(lily);

    let tulip = new flower();
    tulip.name = "Tulip";
    tulip.price = 100;
    tulip.availableQuantity = 2300;
    this. myFlowerList.push(tulip);

    let carnation = new flower();
    carnation.name = "Carnation";
    carnation.price = 50;
    carnation.availableQuantity = 1500;
    this. myFlowerList.push(carnation);

    let gerbera = new flower();
    gerbera.name = "Gerbera";
    gerbera.price = 50;
    gerbera.availableQuantity = 1500;
    this. myFlowerList.push(gerbera);

    let orchid = new flower();
    orchid.name = "Orchid";
    orchid.price = 50;
    orchid.availableQuantity = 1500;
    this. myFlowerList.push(orchid);

  }

  trackFlowers(index,flower){
    return flower?flower.name:undefined
  }
}

This chapter I am going to explain how you can do the styling to our flower store app. There are different kind of CSS frameworks you can use to style you app.

Such as:

1.       Angular Material

2.       ngx-bootstrap

3.       NG bootstrap

4.       Prime NG

I am planning to use PrimeNG styling framework to style our flower store app.

PrimeNG has more than 80 UI component and it is a collection of rich UI components for Angular. All widgets are open source and free to use under MIT License.

How to Install Prime NG

1.   Run  

npm install primeng –save

2.       Run

npm install primeicons –save

3.       Run

npm install font-awesome --save

4.       Run

npm install @angular/cdk –save

Now we are done with installing Prime NG to out flower store app. If you check your package json you will see below list of libraries.

Add below code to your angualr.json file style section.    

"styles": [
              "src/styles.scss",
              "./node_modules/primeicons/primeicons.css",
              "./node_modules/primeng/resources/themes/nova-light/theme.css",
             "./node_modules/primeng/resources/primeng.min.css"
            ],

If you are using Angular 8 after above installation you will get error 

Broswerslist: caniuse-lite is outdated. Please run next command `npm update' 
node_modules/primeng/api/megamenuitem.d.ts(30,27): error TS2304: Cannot find name 'QueryParamsHandling'.

node_modules/primeng/api/menuitem.d.ts(1,10): error TS2305: Module '"../../@angular/router/router"' has no exported member 'QueryParamsHandling'.

     when you run ng serve command. 

This is because there is a mismatch between the Angular version and the PrimeNG version. To resolve this, you can run below two commands to uninstall current version and install Angular 8 compatible PrimeNG version.

npm uninstall primeng

npm install primeng@8.0.1

Now you are ready to use PrimeNg to style your flower store app.
