Angular MFE Host Application Setup | Complete Configuration Guide

The host application (shell) is the central hub of your Micro Frontend architecture. It manages routing, navigation, authentication, and loads remote MFEs at runtime. This guide provides comprehensive instructions for building a robust host application.

🏗️ Host Application Architecture

Core Responsibilities

1. Navigation & Routing: Global navigation and route management
2. Authentication: Centralized user authentication and authorization
3. Layout Management: Common headers, footers, and layout structure
4. MFE Loading: Dynamic loading and management of remote MFEs
5. State Management: Shared application state across MFEs
6. Error Handling: Global error handling and fallback mechanisms

🎨 Step 1: Enhanced Layout and Navigation

1.1 Create Layout Module

cd host-banking-app
ng generate module layout
ng generate component layout/header
ng generate component layout/footer
ng generate component layout/sidebar
ng generate component layout/main-layout

1.2 Create Header Component

header.component.html:

<header class="app-header">
  <div class="header-container">
    <!-- Brand Section -->
    <div class="brand-section">
      <div class="logo">
        <img src="/assets/images/logo.png" alt="Banking Logo" class="logo-img">

🔐 Step 2: Authentication Module

2.1 Create Authentication Module

ng generate module auth --routing
ng generate component auth/login
ng generate component auth/register
ng generate service auth/auth
ng generate guard auth/auth
ng generate interface models/user

2.2 User Interface

models/user.interface.ts:

export interface User {
  id: string;
  email: string;
  name: string;
  role: 'customer' | 'admin' | 'manager';
  avatar?: string;
  permissions: string[];
  lastLogin?: Date;
  preferences: {
    theme: 'light' | 'dark';
    language: string;
    notifications: boolean;
  };
}

export interface LoginCredentials {
  email: string;
  password: string;
  rememberMe?: boolean;
}

export interface RegisterData {
  email: string;
  password: string;
  confirmPassword: string;
  firstName: string;
  lastName: string;
  phone?: string;
}

2.3 Authentication Service

auth/auth.service.ts:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { BehaviorSubject, Observable, of, throwError } from 'rxjs';
import { map, catchError, tap } from 'rxjs/operators';
import { User, LoginCredentials, RegisterData } from '../models/user.interface';

@Injectable({
  providedIn: 'root'

  public currentUser$ = this.currentUserSubject.asObservable();

  private tokenKey = 'banking_auth_token';
  private userKey = 'banking_user_data';

  constructor(private http: HttpClient) {
    // Load user from localStorage on service initialization
    this.loadUserFromStorage();
  }

  get currentUser(): User | null {
    return this.currentUserSubject.value;
  }

  get isAuthenticated(): boolean {
    return !!this.currentUser && !!this.getToken();
  }

  login(credentials: LoginCredentials): Observable<User> {
    // In a real app, this would call your authentication API
    // For demo purposes, we'll use mock authentication
    return this.mockLogin(credentials).pipe(
      tap(user => {
        this.setAuthData(user, 'mock-jwt-token');
      }),
      catchError(error => {

  logout(): void {
    localStorage.removeItem(this.tokenKey);
    localStorage.removeItem(this.userKey);
    this.currentUserSubject.next(null);
  }

  refreshToken(): Observable<string> {
    // In a real app, refresh the JWT token
    return of('refreshed-mock-jwt-token').pipe(
      tap(token => {
        localStorage.setItem(this.tokenKey, token);
      })
    );
  }

  getToken(): string | null {
    return localStorage.getItem(this.tokenKey);
  }

  private mockLogin(credentials: LoginCredentials): Observable<User> {
    // Mock authentication logic
    const mockUser: User = {
      id: '1',
      email: credentials.email,
      name: 'John Doe',
      role: 'customer',
      avatar: '/assets/images/default-avatar.png',
      permissions: ['dashboard:read', 'transactions:read', 'loans:calculate'],
      lastLogin: new Date(),
      preferences: {
        theme: 'light',
        language: 'en',
        notifications: true
      }
    };

    // Simulate API delay
    return new Promise((resolve) => {
      setTimeout(() => {
        if (credentials.email === 'demo@banking.com' && credentials.password === 'demo123') {
          resolve(mockUser);
        } else {
          throw new Error('Invalid credentials');
        }
      }, 1000);
    }).then(user => of(user as User)).catch(error => throwError(error));
  }

  private mockRegister(registerData: RegisterData): Observable<User> {
    const mockUser: User = {
      id: Date.now().toString(),
      email: registerData.email,
      name: `${registerData.firstName} ${registerData.lastName}`,
      role: 'customer',
      permissions: ['dashboard:read', 'transactions:read', 'loans:calculate'],
      lastLogin: new Date(),
      preferences: {

  }

  private setAuthData(user: User, token: string): void {
    localStorage.setItem(this.tokenKey, token);
    localStorage.setItem(this.userKey, JSON.stringify(user));
    this.currentUserSubject.next(user);
  }

  private loadUserFromStorage(): void {
    const userData = localStorage.getItem(this.userKey);

        console.error('Error loading user from storage:', error);
        this.logout();
      }
    }
  }

2.4 Authentication Guard

auth/auth.guard.ts:

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { AuthService } from './auth.service';

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanActivate {

  constructor(
    private authService: AuthService,
    private router: Router
  ) {}

  canActivate(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean> | Promise<boolean> | boolean {

    if (this.authService.isAuthenticated) {
      return true;
    }

    // Store the attempted URL for redirecting after login
    localStorage.setItem('returnUrl', state.url);

    // Redirect to login page
    this.router.navigate(['/auth/login']);
    return false;
  }
}

⚙️ Step 3: Core Services

3.1 Loading Service

services/loading.service.ts:

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class LoadingService {
  private loadingSubject = new BehaviorSubject<boolean>(false);
  public loading$ = this.loadingSubject.asObservable();

  private activeRequests = 0;

  show(): void {
    this.activeRequests++;
    this.loadingSubject.next(true);
  }

  hide(): void {
    this.activeRequests--;
    if (this.activeRequests <= 0) {
      this.activeRequests = 0;
      this.loadingSubject.next(false);
    }
  }

  isLoading(): boolean {
    return this.loadingSubject.value;
  }
}

3.2 Error Service

services/error.service.ts:

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class ErrorService {
  private errorSubject = new BehaviorSubject<string>('');
  public error$ = this.errorSubject.asObservable();

  showError(message: string): void {
    this.errorSubject.next(message);

    // Auto-clear error after 5 seconds
    setTimeout(() => {
      this.clearError();
    }, 5000);
  }

  clearError(): void {
    this.errorSubject.next('');
  }
}

3.3 MFE Configuration Service (Enhanced)

services/mfe-config.service.ts:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { BehaviorSubject, Observable, throwError } from 'rxjs';
import { catchError, map, tap } from 'rxjs/operators';
import { environment } from '../../environments/environment';

export interface MfeConfig {
  [key: string]: string;

  url: string;
  exposedModule: string;
  displayName: string;
  description: string;
  version: string;
  health: 'healthy' | 'unhealthy' | 'unknown';
}

@Injectable({
  providedIn: 'root'
})
export class MfeConfigService {
  private configSubject = new BehaviorSubject<MfeConfig>({});
  public config$ = this.configSubject.asObservable();

  private mfeHealthSubject = new BehaviorSubject<{ [key: string]: MfeInfo }>({});
  public mfeHealth$ = this.mfeHealthSubject.asObservable();

  constructor(private http: HttpClient) {
    this.loadConfig();
  }

  private async loadConfig(): Promise<void> {
    try {
      const config = await this.http.get<any>('/assets/mf.manifest.json').toPromise();
      const envConfig = config[environment.production ? 'production' : 'development'];
