Angular 18 Pagination with NGX Pagination Example

In this post, I will show you how to implement server side pagination in angular 18 application.

we will use ngx-pagination npm library to create simple pagination with angular 18 app. then we will use "https://reqres.in/" demo API to retrieve users with pagination. we will create service to get users detail with first name, last name, and email and display. you can follow the below step to done this example.

Step for Server Side Pagination in Angular 18

• Step 1: Create Angular 18 Project
• Step 2: Install ngx-pagination
• Step 3: export provideHttpClient()
• Step 4: Create Service for API
• Step 5: Use Service to Component
• Step 6: Updated View File
• Run Angular App

Let's follow the steps:

Step 1: Create Angular 18 Project

You can easily create your angular app using below command:

ng new my-new-app

Step 2: Install ngx-pagination

In this step, we will install ngx-pagination package. let's install by following command:

npm install ngx-pagination --save

Step 3: export provideHttpClient()

In this step, we need to export provideHttpClient() to app.config.ts file. so let's import it as like bellow:

src/app/app.config.ts

import { ApplicationConfig } from '@angular/core';
import { provideRouter } from '@angular/router';
  
import { routes } from './app.routes';
import { provideAnimations } from '@angular/platform-browser/animations';
  
import { provideHttpClient } from '@angular/common/http';
   
export const appConfig: ApplicationConfig = {
  providers: [provideRouter(routes), provideAnimations(), provideHttpClient()]
};

Step 4: Create Service for API

Here, we need to create service for http client request. we will create service file and write client http request code. this service will use in our component file.

you have to use service for getting pagination records. if you want to create your own rest api then you can follow bellow tutorials:

1. How to Create a REST API using Node JS?

2. Laravel REST API using Passport

3. Codeigniter REST API using Passport

Here, i will use "https://reqres.in/" website demo api for getting paginate users. you can see bellow json response we need:

API Response:

So let's create service and put bellow code:

ng g s services/users

Now let's add code as like bellow:

src/app/services/users.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
  
@Injectable({
  providedIn: 'root'
})
export class UsersService {
  
  private url = 'https://reqres.in/api/users';
     
  constructor(private httpClient: HttpClient) { }
    
  getUsers(page: number){
    return this.httpClient.get(this.url + '?page=' + page);
  }
}

Step 5: Use Service to Component

Now we have to use this services to our app component. So let's updated code as like bellow:

src/app/app.component.ts

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';
  
import { NgxPaginationModule } from 'ngx-pagination';
import { UsersService } from './services/users.service';
  
@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule, RouterOutlet, NgxPaginationModule],
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  
  users:any;
  p: number = 1;
  total: number = 0;
      
  constructor(private service:UsersService) {}
      
  /*------------------------------------------
  --------------------------------------------
  About 
  --------------------------------------------
  --------------------------------------------*/
  ngOnInit() {
    this.getUsers();
  }
    
  /**
   * Write code on Method
   *
   * @return response()
   */
  getUsers(){
      this.service.getUsers(this.p)
        .subscribe((response: any) => {
          this.users = response.data;
          this.total = response.total;
        });
  } 
    
  /**
   * Write code on Method
   *
   * @return response()
   */
  pageChangeEvent(event: number){
      this.p = event;
      this.getUsers();
  }
    
}

Step 6: Updated View File

Now here, we will updated our html file. let's put bellow code:

src/app/app.component.html

<div class="container">
  <h1>Angular 18 Pagination Example - ItSolutionStuff.com</h1>
   
  <table class="table table-bordered">
    <tr>
      <th>ID</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Email</th>
    </tr>
    <tr *ngFor="let user of users| paginate: { itemsPerPage: 6, currentPage: p, totalItems: total }">
        <td>{{ user.id }}</td>
        <td>{{ user.first_name }}</td>
        <td>{{ user.last_name }}</td>
        <td>{{ user.email }}</td>
    </tr>
  </table>  
  
  <pagination-controls (pageChange)="pageChangeEvent($event)"></pagination-controls>
</div>
