Today, We want to share with you Angular 6 CRUD Operations Application.
In this post we will show you MEAN Stack Angular 6 CRUD Web Application, hear for Angular 6 CRUD Example Tutorials from Scratch we will give you demo and example for implement.
In this post, we will learn about Angular 6 CRUD Example Using MySQLi Database with an example.
Angular 6 CRUD Operations Application
There are the Following The simple About Angular 6 CRUD Operations Application Full Information With Example and source code.
This Lovely Post is about simple building Angular 6 CRUD application easy way to step by step.I shall be creating a sample authentication login application with angular 6 CRUD operations post-login with database sample main service REST APIs.I shall be also some methods integrating POST and GET HttpClientModule and angular 6 RouterModule.
Angular 6 CRUD Project
Generating Angular 6 Project
ng new angular6-example
Angular 6 Project Structure
I shall have multiple angular 6 components create such as signin and add-student, edit-student, create-student. Once an admin signin sucessfully,and then he can perform student Angular 6 CRUD operation.Following are the run this commands to generate our angular 6 components.For More Details Angular 6 Folder Project Structure
ng g component signin ng g component add-student ng g component edit-student ng g component list-student
Angular CLI Useful Commands
ng g class my-new-class ng g component my-new-component ng g directive my-new-directive ng g enum my-new-enum ng g guard my-new-guard ng g interface my-new-interface ng g module my-module ng g pipe my-new-pipe ng g service my-new-service
Angular 6 Routing
There Following is our angular 6 routing configurtion with Angular 6 Components
app.routing.ts
import { RouterModule, Routes } from '@angular/router';
import {SigninComponent} from "./signin/signin.component";
import {AddStudentComponent} from "./add-student/add-student.component";
import {ListStudentComponent} from "./list-student/list-student.component";
import {EditStudentComponent} from "./edit-student/edit-student.component";
const routes: Routes = [
{ path: 'signin', component: SigninComponent },
{ path: 'add-student', component: AddStudentComponent },
{ path: 'list-student', component: ListStudentComponent },
{ path: 'edit-student', component: EditStudentComponent },
{path : '', component : SigninComponent}
];
export const routing = RouterModule.forRoot(routes);
AuthenticationService in Angular 6
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { SigninComponent } from './signin/signin.component';
import {routing} from "./app.routing";
import {AuthenticationService} from "./service/auth.service";
import {ReactiveFormsModule} from "@angular/forms";
import {HttpClientModule} from "@angular/common/http";
import { AddStudentComponent } from './add-student/add-student.component';
import { EditStudentComponent } from './edit-student/edit-student.component';
import {ListStudentComponent} from "./list-student/list-student.component";
import {StudentService} from "./service/student.service";
@NgModule({
declarations: [
AppComponent,
SigninComponent,
ListStudentComponent,
AddStudentComponent,
EditStudentComponent
],
imports: [
BrowserModule,
routing,
ReactiveFormsModule,
HttpClientModule
],
providers: [AuthenticationService, StudentService],
bootstrap: [AppComponent]
})
export class AppModule { }
Service in Angular 6 Application
There Following is the angular 6 implementation of our StudentService
let fakeStudents = [{id: 1, studentName: 'jdpatel', sirname: 'Ray', email: '[email protected]'},
{id: 1, studentName: 'jaydeep', sirname: 'Jac', email: '[email protected]'},
{id: 1, studentName: 'krunal', sirname: 'Pan', email: '[email protected]'},
{id: 1, studentName: 'ankit', sirname: 'pb', email: '[email protected]'},
];
return Observable.of(fakeStudents).delay(5000);
student.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import {Student} from "../model/student.model";
@Injectable()
export class StudentService {
constructor(private http: HttpClient) { }
baseUrl: string = 'http://localhost:8080/student-portal/students';
getStudents() {
return this.http.get(this.baseUrl);
}
getStudentById(id: number) {
return this.http.get(this.baseUrl + '/' + id);
}
createStudent(student: Student) {
return this.http.post(this.baseUrl, student);
}
updateStudent(student: Student) {
return this.http.put(this.baseUrl + '/' + student.id, student);
}
deleteStudent(id: number) {
return this.http.delete(this.baseUrl + '/' + id);
}
}
Creating Components in Angular 6
First of all I shall have a signin component in Angular 6 CRUD Operations Application.and then if student successfull then listing pages display.
signin.component.html
<div class="row">
<div class="col-md-6 col-md-offset-2">
<h1>Signin </h1>
<form>
<div class="gst form-group">
<label for="email">Email address:</label>
<div class="error">
<div>Email is required</div>
</div>
</div>
<div class="gst form-group">
<label for="pwd">Password:</label>
<div class="error">
<div>Password is required</div>
</div>
</div>
<button class="btn btn-default">Signin</button>
<div class="error">
<div>Invalid credentials.</div>
</div>
</form>
</div>
</div>
signin.component.ts
import { Component, OnInit } from '@angular/core';
import {FormBuilder, FormGroup, Validators} from "@angular/forms";
import {Router} from "@angular/router";
import {first} from "rxjs/operators";
import {AuthenticationService} from "../service/auth.service";
@Component({
selector: 'app-signin',
templateUrl: './signin.component.html',
styleUrls: ['./signin.component.css']
})
export class SigninComponent implements OnInit {
signinForm: FormGroup;
submitted: boolean = false;
invalidSignin: boolean = false;
constructor(private formBuilder: FormBuilder, private router: Router, private authService: AuthenticationService) { }
onSubmit() {
this.submitted = true;
if (this.signinForm.invalid) {
return;
}
if(this.signinForm.controls.email.value == '[email protected]' && this.signinForm.controls.password.value == 'password') {
this.router.navigate(['list-student']);
}else {
this.invalidSignin = true;
}
}
ngOnInit() {
this.signinForm = this.formBuilder.group({
email: ['', Validators.required],
password: ['', Validators.required]
});
}
}
list-student.component.html
Angular 6 CRUD Operations Application for Display Listing Students.
<div class="col-md-6">
<h2> Student Details</h2>
<button class="btn btn-danger"> Add Student</button>
<table class="table table-striped">

})
};
editStudent(student: Student): void {

localStorage.setItem("editStudentId", student.id.toString());
this.router.navigate(['edit-student']);

Testing Angular 6 Application
run the command ng serve and browser this url
localhost:4200

import {NgModule} from '@angular/core';
import { CommonModule } from '@angular/common';
import {
MatButtonModule, MatCardModule, MatDialogModule, MatInputModule, MatTableModule,
MatToolbarModule
} from '@angular/material';
@NgModule({
