Angular 6 CRUD Example – Part 2

Step 4: Make a JSON server that serves the simple data.

i should the fake dummy data to work with that is why I have to use one package called as a json-server for this Example. With it, I can make a fake server side called REST api.

npm install -g json-server

make one file called Student.json . so us add the following some data inside like as a Student.json file.

// Student.json 

{
    "students": [{
        "id": 1,
        "name": "ND",
        "country": "Mumbai",
    "gender":"Male",
    "department":"Google adsense"
    }, {
        "id": 2,
        "name": "krulana",
        "country": "gova",
    "gender":"FEMale",
    "department":"Youtube"
    },{
        "id": 3,
        "name": "jaydeeo",
        "country": "rajkot",
    "gender":"Male",
    "department":"SEO"
    }]
}

And then, first of all the start the pure JSON server using the following some command.

json-server --watch Student.json

Step 5: Setup HttpClient for service.

Angular 6 is full best Frontend Framework custom javascripts, therefor it has depenedet HTTP module. therefor first let us configure inside Like as app.module.ts file.

// app.module.ts

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

 imports: [
    BrowserModule,
    RouterModule.forRoot(routes),
    HttpClientModule,
],

And then, make models folder inn this file and inside models folder, make one file called like as a student.model.ts.

// student.model.ts

export class Student {
    id: number;
    name: string;
    country: string;
    gender: string;
    department: string;
}

// student.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable()
export class StudentService {
    LIVE_URI = 'http://localhost:3000';
    constructor(private httpClient: HttpClient) { }
    getStudents() {
        return this.httpClient.get(`${this.LIVE_URI}/students`);
    }
}

And then, import student.service.ts service file data and student.model.ts model file inside this file list-students.component.ts file.

// list-students.component.ts

import { Component, OnInit } from '@angular/core';
import { Student } from '../models/student.model';
// Import StudentService
import { StudentService } from './student.service';

@Component({
  selector: 'app-list-students',
  templateUrl: './list-students.component.html',
  styleUrls: ['./list-students.component.css']
})
export class ListStudentsComponent implements OnInit {
  students: Student[];
  constructor(private _studentService: StudentService) { }

  ngOnInit() {
    this.getStudents();
  }

  public getStudents() {
    this._studentService.getStudents().subscribe((data: Student[]) => {
      this.students = data;
    });
  }
}

js Loop through that simple data and view it as a DOM HTML table inside list-students.component.html file.

<table class="table table-bordered">
    <thead>
        <tr>
            <th>stud Id</th>
            <th>stud Name</th>
            <th>stud City</th>
            <th>stud Gender</th>
            <th>stud Department</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>{{student.id}}</td>
            <td>{{student.name}}</td>
            <td>{{student.country}}</td>
            <td>{{student.gender}}</td>
            <td>{{student.department}}</td>
        </tr>
    </tbody>
</table>
