  "apps": [
    { 
      "styles": [
  // Add Start --------------------------------------------
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
  // Add End --------------------------------------------
        "styles.css"
      ],
    }
  ],

Get Firebase config data

Of course you need to have Firebase account and your own project. If you don't have the account, visit the following page in advance and make your own project.

https://www.firebase.com/login/

You need to get Firebase config data from your own project page. This url is as follows.

https://console.firebase.google.com/project/your-project-name/overview

You need the following parameters

apiKey
authDomain
databaseURL
projectId
storageBucket
messagingSenderId

In "Overview" page, click Web Application icon.

Then those parameters above will be shown. Copy them.

Modify environment.ts

Change directory to "src/app/environments".

$ cd src/app/environments

You will find environment.ts and environment.prod.ts. Modify these files as follows. In firebaseConfig, paste the data above.

export const environment = {
  production: true,
  // Add Start --------------------------------------------
  firebase: {
    apiKey: '"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    authDomain: 'xxxxxxxxxxxxxxxxxx.firebaseapp.com',
    databaseURL: 'https://xxxxxxxxxxxxxxxxxx.firebaseio.com',
    projectId: 'xxxxxxxxxxxxx',
    storageBucket: 'xxxxxxxxxxxxx.appspot.com',
    messagingSenderId: 'xxxxxxxxxxxxxxxxxxxxx'
  }
  // Add End --------------------------------------------
};

Modify app.module.ts

Change directory to "src/app".

$ cd src/app

You will find app.module.ts. Modify this file as follows. AppRoutingModule and CoreModule will be made later.

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

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

  // Add Start --------------------------------------------
import { O2AuthFsModule　} from 'o2-auth-fs';
import { AppRoutingModule } from './app-routing.module';
import { CoreModule } from './core/core.module';
  // Add End --------------------------------------------

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
  // Add Start --------------------------------------------
    AppRoutingModule,
    CoreModule,
    O2AuthFsModule.forRoot()
  // Add End --------------------------------------------
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Modify app.component.ts

In the same directory, you will find app.component.ts . In this file, modify as follows.

import { Component, OnInit  } from '@angular/core';
  // Add Start --------------------------------------------
import { environment } from './../environments/environment';
import * as firebase from 'firebase';
  // Add End --------------------------------------------

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'app-root';
  // Add Start --------------------------------------------
  loadedFeature = 'home';
  ngOnInit() {
    firebase.initializeApp(environment.firebase);
  }
  onNavigate(feature: string) {
    this.loadedFeature = feature;
  }
  // Add End --------------------------------------------
}

Add app-routing.module.ts

You had better independent modules for future. So add app.routing.module.ts in the project root directory. You need add flat option as follows.

$ ng generate module app-routing --flat

Add Core Module

You maybe need home page and header. They had better be included in core module which is almost always resided. At first you need add core module as foloows.
