Angular 11 Crud Tutorial with Service - Get Users

Hello to all, welcome back on my blog. Today in this blog post, I am going to show you, Angular 11 Crud Tutorial with Service – Get Users.

Angular Crud Example

Angular 11 came and if you are new then you must check below link:

  1. Angular11 Basic Tutorials

Friends now I proceed onwards and here is the working code snippet for Angular 11 Crud Tutorial with Service – Get Users and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 11 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 angularcrud //Create new Angular Project

cd angularcrud // 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 bootstrap(for good looks), jquery to support bootstrap  modules into our angular application:

npm i bootstrap --save

npm i jquery --save

 

3. Now friends, here we need to add below  into our angular.json file to get modules styles and scripts:

...
"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css",
              
              
            ],
            "scripts": [
              ...
              "node_modules/jquery/dist/jquery.min.js", 
              "node_modules/bootstrap/dist/js/bootstrap.min.js", 
              
              
            ]
...

 

4. Now friends, we need to run below commands to create service file and run our angular project:

ng g service crud

ng serve

 

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

...

import { HttpClientModule } from '@angular/common/http';

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

 

6. Now friends we just need to add below code into src/app/crud.service.ts file:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable({
  providedIn: 'root'
})
export class CrudService {

  constructor(private http:HttpClient) { }
  public getusers()
    {
        //API request to php file
        return this.http.get('http://localhost/users.php');
    }
}

 

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

...

import { CrudService } from './crud.service'; 

export class AppComponent  {
...
  data = [];
  constructor(private crudservice: CrudService) {}

  ngOnInit() {
  
  
    this.crudservice.getusers().subscribe((ret: any[])=>{
        console.log(ret);
        this.data = ret;
      })
    }
}

 

8. Now friends we just need to add below code into src/app/app.component.html file to see the output on browser:

<table class="table table-hover table-bordered">
    <thead>
      <tr>
        <th>ID</th>
        <th>Email</th>
        <th>Username</th>
       
      </tr>
    </thead>
    <tbody>
   
       
          <tr *ngFor="let group of data">
            <td>{{group.id}}</td>
            <td>{{group.email}}</td>
            <td>{{group.username}}</td>
   
           
          </tr>
       
     
     
      
    </tbody>
  </table>

 

9. Now friends here is my php code snippet to fetch data and show  into angular 11  and I added this code into my xampp/htdocs/users.php file:

//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

<?php
//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

$servername = "localhost";
$username   = "root";
$password   = "";
$dbname     = "users";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
    //get all users details
    $trp = mysqli_query($conn, "SELECT * from userdetails");
    $rows = array();
    while($r = mysqli_fetch_assoc($trp)) {
        $rows[] = $r;
    }
    print json_encode($rows);

?>
