Angular 14 Server Side Pagination Tutorial

In this tutorial, I will give you step by step server side pagination example using ngx-pagination npm package which you can use angular 14. so let's follow the below step to make this example.

Step 1: Create New App

You can easily create your angular 14 app using bellow 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: Import Modules

In this step, we need to import HttpClientModule and NgxPaginationModule to app.module.ts file. so let's import it as like bellow:

src/app/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
  
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
  
import { NgxPaginationModule } from 'ngx-pagination';
    
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    NgxPaginationModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

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.

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, OnInit } from '@angular/core';
import { UsersService } from './services/users.service';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  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 Pagination Example - codewale.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>
