Hello friends, welcome back to my blog. Today in this blog post, I am going to tell you, ANGULAR 13 – ANGULAR MATERIAL JSON SERVER CRUD OPERATIONS – Get Users.

Guys before starting this please must check this tutorial : Crud Project Setup

Material Angular Data Table

Angular 13 came and very soon Angular 14 will come and if you are new then you must check below two links:

  1. Angular13 Basic Tutorials

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 13 setup and for this we need to run below commands but if you already have angular 11 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angularmaterial //Create new Angular Project

cd angularmaterial // Go inside the Angular Project Folder

ng serve --open // Run and Open the Angular Project

http://localhost:4200/ // Working Angular Project Url

2. Now friends, here we need to run below commands into our project terminal to install angular material modules into our angular application:

ng add @angular/material

3. Now friends we just need to add below code into src/app/app.component.html file to get final out on the web browser:

<div class="mat-elevation-z8">
    <table mat-table [dataSource]="dataSource">
  
      <!-- id Column -->
      <ng-container matColumnDef="id">
        <th mat-header-cell *matHeaderCellDef> No. </th>
        <td mat-cell *matCellDef="let element"> {{element.id}} </td>
      </ng-container>
  
      <!-- Name Column -->
      <ng-container matColumnDef="name">
        <th mat-header-cell *matHeaderCellDef> Name </th>
        <td mat-cell *matCellDef="let element"> {{element.name}} </td>
      </ng-container>
  
      <!-- email Column -->
      <ng-container matColumnDef="email">
        <th mat-header-cell *matHeaderCellDef> Email </th>
        <td mat-cell *matCellDef="let element"> {{element.email}} </td>
      </ng-container>
  
  
      <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
      <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
    </table>
  
    <mat-paginator [pageSizeOptions]="[5, 10, 20]"
                   showFirstLastButtons 
                   aria-label="Select page of periodic elements">
    </mat-paginator>
  </div>

4. Now friends we just need to add below code into src/app/app.module.ts file:

...
import {  MatTableModule } from '@angular/material/table';
import {  MatPaginatorModule } from '@angular/material/paginator';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
 ...
  imports: [
   ...
    MatPaginatorModule,
    MatTableModule,
    HttpClientModule
  ],
  ...

5. Now friends we just need to add below code into src/app/app.component.ts file:

...
import { ViewChild } from '@angular/core';
import {MatPaginator} from '@angular/material/paginator';
import {MatTableDataSource} from '@angular/material/table';
import { HttpClient } from '@angular/common/http';
export class AppComponent {
  ...

  //Material table columns
  displayedColumns: string[] = ['id', 'name', 'email'];
  //Table Data Source
  @ViewChild(MatPaginator) paginator :any = MatPaginator;

  //Dynamic Data Variable
  usersData:any;
  constructor(private http: HttpClient){}

  @ViewChild(MatPaginator, {static: true}) paginator: MatPaginator;

  ngOnInit() {
       //get request from web api and this web api is totaly free to use
       this.http.get('http://localhost:4000/users').subscribe(data => {
       this.usersData = data;
     
        //Data Table Data Source and pagination with dynamic data
        this.dataSource = new MatTableDataSource(this.usersData);
        this.dataSource.paginator = this.paginator
        
     
          }, error => console.error(error));
   
  
  }
}
export interface PeriodicElement {
   name: string;
  position: number;
  email: string;
 
}

6. Now guys we need to add below code into project/json-server/db.json file:

{
    "users": [
      {"id": 1, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 2, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 3, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 4, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 5, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 6, "name": "Jassa", "email": "therichposts@gmail.com"},
      {"id": 7, "name": "Jassa", "email": "therichposts@gmail.com"}
  
    ]
  }

Friends in the end must run ng serve command into your terminal to run the angular 13 project.

Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.

Note: Friends, In this post, I just tell the basic setup and things, you can change the code according to your requirements.
