Creating the PhoneBook Component

Create a phonebook folder inside src/app/main folder and add a new typescript file (phonebook.component.ts) in the phonebook folder as shown below:

import { Component, Injector } from '@angular/core';
import { AppComponentBase } from '@shared/common/app-component-base';
import { appModuleAnimation } from '@shared/animations/routerTransition';

@Component({
    templateUrl: './phonebook.component.html',
    animations: [appModuleAnimation()]
})

export class PhoneBookComponent extends AppComponentBase {
    constructor(
        injector: Injector
    ) {
        super(injector);
    }
}

We inherited from AppComponentBase which provides some common functions and fields (like localization and access control) for us. It's not required, but makes our job easier. Now, we can return back to main-routing.module.ts and add import statement for the newly created PhoneBookComponent class:

import { PhoneBookComponent } from './phonebook/phonebook.component';

As we declared in phonebook.component.ts we should create a phonebook.component.html view in the same phonebook folder:

<div [@routerTransition]>
    <div class="m-subheader ">
        <div class="d-flex align-items-center">
            <div class="mr-auto col-sm-6">
                <h3 class="m-subheader__title m-subheader__title--separator">
                    <span>{{"PhoneBook" | localize}}</span>
                </h3>
            </div>
        </div>
    </div>
    <div class="m-content">
        <div class="m-portlet m-portlet--mobile">
            <div class="m-portlet__body">
                <p>PHONE BOOK CONTENT COMES HERE!</p>
            </div>
        </div>
    </div>
</div>

l (lower case 'L') function comes from AppComponentBase and used to easily localize texts. [@routerTransition] attribute is required for page transition animation.

And finally, Angular requires to relate every component to a module. So, we are making the following changes on the main.module.ts:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';

import { DashboardComponent } from './dashboard/dashboard.component';
import { PhoneBookComponent } from './phonebook/phonebook.component';

import { ModalModule, TabsModule, TooltipModule } from 'ngx-bootstrap';
import { AppCommonModule } from '@app/shared/common/app-common.module';
import { UtilsModule } from '@shared/utils/utils.module';
import { MainRoutingModule } from './main-routing.module';

@NgModule({
    imports: [
        CommonModule,
        FormsModule,
        ModalModule,
        TabsModule,
        TooltipModule,
        AppCommonModule,
        UtilsModule,
        MainRoutingModule
    ],
    declarations: [
      DashboardComponent,
      PhoneBookComponent
    ]
})
export class MainModule { }

Added an import statement and added PhoneBookComponent to declarations array. Now, we can refresh the page to see the new added page:

Phonebook empty

Note: Angular-cli automatically re-compiles and refreshes the page when any changes made to any file in the application.
