/app/app.component.ts

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
    selector: 'app',
    templateUrl: 'app.component.html'
})

export class AppComponent implements OnInit {
    membersForm: FormGroup;
    submitted = false;

    constructor(private formBuilder: FormBuilder) { }

    ngOnInit() {
        this.membersForm = this.formBuilder.group({
            memberfName: ['', Validators.required],
            memberlName: ['', Validators.required],
            email: ['', [Validators.required, Validators.email]],
            password: ['', [Validators.required, Validators.minLength(6)]]
        });
    }

    // convenience getter for easy access to form fields
    get validfrm() { return this.membersForm.controls; }

    onSubmit() {
        this.submitted = true;

        // stop here if form is invalid
        if (this.membersForm.invalid) {
            return;
        }

        alert('SUCCESS!! :-)\n\n' + JSON.stringify(this.membersForm.value))
    }
}

/app/app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ReactiveFormsModule } from '@angular/forms';

import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    ReactiveFormsModule

It would be Best to More Easy Step by step indicate which all the comman Header, Footer and Sidebar page a student is find easly currently on in the display Menu on left sidebar, supportd by putting a dynamic class to the icon chnage that will create This is background blue ore any color? Sure!

So lets start, first of all the go to the /src/app/sidebar/sidebar.component.ts Path file and add the following add the source code:

import { Component, OnInit } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';

export class SidebarComponent implements OnInit {

  currentUrl: string;
	// default Angular 6 Open File
  constructor(private router: Router) {
    router.events.subscribe((_: NavigationEnd) => this.currentUrl = _.url);
  }

  ngOnInit() {}

}

and then Open the simple file sidebar.component.html This path as well as some source code update it to data content match:

<nav>
  <ul>
    <li>
      <a routerLink="" [class.current]="currentUrl == '/'">
        <i class="material-icons">supervised_student_circle</i>
      </a>
    </li>
    <li>
      <a routerLink="teachers" [class.current]="currentUrl == '/teachers'">
