• app.component.html:

HTML

<div style="width: 80%;">
    <h1 style="color: green;">
          GeeksforGeeks
      </h1>
    <h2>

    <p-button (click)="GetConfirm()"
              label="Click Here">
      </p-button>
</div>

• app.component.ts:

Javascript

import { Component } from "@angular/core";
import { ConfirmationService } from "primeng/api";
import { PrimeNGConfig } from "primeng/api";

@Component({
    selector: "app-root",
    templateUrl: "./app.component.html",
    styles: [],
    providers: [ConfirmationService]
})

export class AppComponent {
    constructor(
        private confirmationService: ConfirmationService,
        private primengConfig: PrimeNGConfig
    ) { }

    GetConfirm() {
        this.confirmationService.confirm({
            message: "Angular PrimeNG ConfirmDialog Component",

    }

    onHide() {
        alert("Hi Geek!! I am closed");
    }
}

• app.module.ts:

Javascript

import { NgModule } from "@angular/core";
import { BrowserModule }
    from "@angular/platform-browser";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";
import { AppComponent } from "./app.component";
import { ButtonModule } from "primeng/button";
import { ConfirmDialogModule }
    from "primeng/confirmdialog";

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        ConfirmDialogModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule {}
