Get ngx-Bootstrap using below command:

Import and update app.module.ts as below to include ngx-Bootstrap/Pagination

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { PaginationModule } from 'ngx-bootstrap/pagination';

@NgModule({

declarations: [

      ...

],

imports: [

      BrowserModule

      ,PaginationModule.forRoot()

providers: [],

bootstrap: []

})

Import and change the component.ts as below to include ngx-Bootstrap/Pagination

import { NgModule } from '@angular/core';
import { PageChangedEvent } from 'ngx-bootstrap/pagination';

@Component({

selector: 'BasicPagination',

templateUrl:'basicPaginationView.html',

providers: [ProductService]

})

export class BasicPaginationComponent implements OnInit {

currentPage: number;

maxPageSize: number;

ngOnInit() : void {}

pageChanged(event: PageChangedEvent): void {

      const startItem = (event.page - 1) * event.itemsPerPage;

      const endItem = event.page * event.itemsPerPage;

      this.returnedProducts = this.products.slice(startItem, endItem);

}

}

Add below code to .html file which will include Pagination control to the view

<div class="pull-right">

<!-- pager -->

<pagination id="test" [totalItems] = totalProducts [itemsPerPage]=maxPageSize [directionLinks]="false" (pageChanged)="pageChanged($event)"></pagination>

</div>

With this I am concluding the illustration. Feel free to share your feedback. Happy Programming !!!
