Starting a new Angular project can feel like moving into a massive, empty mansion. You know there are rooms for everything, but figuring out where to put the couch (and where the plumbing goes) takes a bit of planning.

Here is a comprehensive breakdown of a professional-grade Angular skeleton.

Installation & Prerequisites

Before you build, you need the tools. Ensure you have Node.js (LTS version) installed.

Install Angular CLI globally:

npm install -g @angular/cli
Create a new project:

ng new my-awesome-app
- Tip: Select SCSS for styling (it's more powerful) and enable Server-Side Rendering (SSR) if you care about SEO.
Navigate and Start:

cd my-awesome-app

ng serve --open

Professional Folder Structure

A "flat" structure works for tutorials, but for real-world apps, you want a modular approach.

src/app/core/: The "singleton" layer. Put services that should only have one instance here (e.g., AuthService, ApiService) and your global guards/interceptors.
src/app/shared/: The "reusable" layer. This contains components (buttons, spinners), pipes, and directives that are used across multiple feature modules.
src/app/features/ (or pages/): This is where the actual business logic lives. Each feature (e.g., dashboard, user-profile) gets its own folder with its own components and routing.
src/assets/: Static files like images, icons, and JSON translation files.
src/environments/: Configuration for different stages (e.g., environment.ts for dev and environment.prod.ts for production).

Key Configuration Files

These files are the "brain" of your project.

File	Purpose
`angular.json`	The CLI configuration. Defines build targets, asset paths, and global styles/scripts.
`package.json`	Manages dependencies and scripts (like `npm start` or `npm run build`).
`tsconfig.json`	TypeScript compiler settings. (Pro tip: use `paths` here to avoid `../../../../` import hell).
`app.config.ts`	(In modern Angular) The central place to provide global providers, routing, and animations.

The Essential "Skeleton" Checklist

To move from a "default" app to a "production-ready" app, you should usually add these immediately:

Tailwind CSS or Angular Material: Don't reinvent the wheel for styling unless you have a very specific design system.
Prettier & ESLint: Keeps the code clean. Use ng add @angular-eslint/schematics.
State Management: If your app is huge, consider NgRx or Signals (the modern way) to manage data flow.
HTTP Interceptor: To automatically attach Auth tokens to every outgoing API request.

Standard Component Skeleton

Every component you generate via ng generate component will follow this four-file pattern:

.ts: The logic (TypeScript).
.html: The structure.
.scss: The style (scoped specifically to this component).
.spec.ts: The unit tests (don't ignore these, your future self will thank you).

Note on Standalone Components: Modern Angular (v17+) defaults to "Standalone" components. This means you no longer need huge app.module.ts files! Each component imports exactly what it needs.

Since you're ready to build out the meat of that skeleton, let's focus on the "Connective Tissue"—the Core Service and the HTTP Interceptor. These are the two most critical pieces for a functional, professional Angular app.

The Global API Service (`core/services/api.service.ts`)

Instead of injecting HttpClient into every single component, you should use a central API service. This allows you to change your base URL or handle global errors in one place.

TypeScript

import { Injectable } from '@angular/core';
import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs';
import { environment } from '../../../environments/environment';

@Injectable({ providedIn: 'root' })
export class ApiService {
  private readonly baseUrl = environment.apiUrl;

  constructor(private http: HttpClient) {}

  get<T>(path: string, params: HttpParams = new HttpParams()): Observable<T> {
    return this.http.get<T>(`${this.baseUrl}${path}`, { params });
  }

  post<T>(path: string, body: object = {}): Observable<T> {
    return this.http.post<T>(`${this.baseUrl}${path}`, body);
  }
}

The Auth Interceptor (`core/interceptors/auth.interceptor.ts`)

In modern Angular (v17+), we use Functional Interceptors. This "skeleton" piece automatically injects your JWT token into every request and catches 401-Unauthorized errors.

TypeScript

import { HttpInterceptorFn, HttpErrorResponse } from '@angular/common/http';
import { inject } from '@angular/core';
import { catchError, throwError } from 'rxjs';
import { AuthService } from '../services/auth.service';

export const authInterceptor: HttpInterceptorFn = (req, next) => {
  const authService = inject(AuthService);
  const token = authService.getToken();

  // Clone the request to add the new header
  const authReq = token 
    ? req.clone({ setHeaders: { Authorization: `Bearer ${token}` } }) 
    : req;

  return next(authReq).pipe(
    catchError((error: HttpErrorResponse) => {
      if (error.status === 401) {
        authService.logout(); // Redirect to login if token expired
      }
      return throwError(() => error);
    })
  );
};

Registering the Skeleton in `app.config.ts`

To make these tools work, you have to "plug them in" at the root of your application.

TypeScript

import { ApplicationConfig } from '@angular/core';
import { provideHttpClient, withInterceptors } from '@angular/common/http';
import { authInterceptor } from './core/interceptors/auth.interceptor';
import { provideRouter } from '@angular/router';
import { routes } from './app.routes';

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideHttpClient(
      withInterceptors([authInterceptor]) // Plug in the interceptor here
    )
  ]
};

The Data Flow Architecture

When your skeleton is set up this way, your data follows a clean, predictable path:

Component calls a Feature Service.
Feature Service calls the Global ApiService.
Interceptor intercepts the request to add a Security Token.
Backend sends data back; Interceptor checks for errors.
Component receives clean data and displays it.

Professional-Tip: Environment Management

Don't forget to define your URLs in src/environments/environment.ts:

TypeScript

export const environment = {
  production: false,
  apiUrl: 'https://api.dev-example.com/v1'
};

Building a Shared UI Component is the best way to see the "Shared" folder philosophy in action. A Reusable Modal is the perfect example because it involves logic (opening/closing), styling, and content projection (letting other components put content inside it).

Creating the Shared Modal

We’ll use Content Projection (<ng-content>) so this modal can act as a shell for any content you throw at it.

Step 1: Generate the Component

ng generate component shared/components/modal --standalone

Step 2: The Logic (`modal.component.ts`)

We use @Input to control the title and visibility, and @Output to notify the parent when the modal should close.

TypeScript

import { Component, Input, Output, EventEmitter } from '@angular/core';
import { CommonModule } from '@angular/common';

@Component({
  selector: 'app-modal',
  standalone: true,
  imports: [CommonModule],
  templateUrl: './modal.component.html',
  styleUrls: ['./modal.component.scss']
})
export class ModalComponent {
  @Input() isOpen = false;
  @Input() title = 'Default Title';
  @Output() close = new EventEmitter<void>();

  closeModal() {
    this.close.emit();
  }
}

Step 3: The Template (`modal.component.html`)

The <ng-content> tag is the "magic" spot where the parent’s HTML will be injected.

HTML

<div class="modal-backdrop" *ngIf="isOpen" (click)="closeModal()">
  <div class="modal-container" (click)="$event.stopPropagation()">
    <div class="modal-header">
      <h3>{{ title }}</h3>
      <button class="close-btn" (click)="closeModal()">&times;</button>
    </div>
    
    <div class="modal-body">
      <ng-content></ng-content>
    </div>
  </div>
</div>

Using the Modal in a Feature

Now, let's see how a feature (like a User Profile) uses this shared component.

The Feature Template

HTML

<button (click)="isModalOpen = true">Edit Profile</button>

<app-modal 
  [isOpen]="isModalOpen" 
  [title]="'Update User Info'" 
  (close)="isModalOpen = false">
  
  <form>
    <label>Username:</label>
    <input type="text" placeholder="Enter new username">
    <button type="submit">Save Changes</button>
  </form>
  
</app-modal>

The Skeleton State: Where we are now

Your project structure should now look like this "Living Skeleton":

core/: Handles the "behind the scenes" (API, Auth, Interceptors).
shared/: Handles the "look and feel" (Modals, Buttons, Data-tables).
features/: Handles the "business" (Login, Dashboard, User Settings).

Next Step: Handling Data with Signals

In modern Angular, we avoid complex RxJS for simple UI state and use Signals. Signals make data updates faster and more readable.

Since you’re already modernizing your skeleton, moving from traditional RxJS observables to Signals is like upgrading from a landline to a smartphone. Signals track exactly where data is used and only update those specific parts of the UI, making your app incredibly snappy.

Why Signals?

In the old way, Angular had to check the entire component tree for changes (Change Detection). With Signals, Angular knows exactly which variable changed and which HTML element needs a refresh.

Refactoring a Service with Signals

Let's create a UserService in your core/ folder that manages the current user's state globally.

TypeScript

import { Injectable, signal, computed } from '@angular/core';

export interface User {
  id: number;
  name: string;
  role: 'admin' | 'user';
}

@Injectable({ providedIn: 'root' })
export class UserService {
  // 1. The writable signal (private so only this service can change it)
  private userSignal = signal<User | null>(null);

  // 2. A read-only version for components to consume
  readonly currentUser = this.userSignal.asReadonly();

  // 3. A computed signal (automatically updates when userSignal changes)
  readonly isAdmin = computed(() => this.userSignal()?.role === 'admin');

  setUser(user: User) {
    this.userSignal.set(user);
  }

  clearUser() {
    this.userSignal.set(null);
  }
}

Using Signals in a Component

In your component, you no longer need to subscribe or unsubscribe. You simply call the signal like a function in your HTML.

The TypeScript (`profile.component.ts`)

TypeScript

import { Component, inject } from '@angular/core';
import { UserService } from '../../core/services/user.service';

@Component({
  selector: 'app-profile',
  standalone: true,
  templateUrl: './profile.component.html'
})
export class ProfileComponent {
  // Inject the service
  userService = inject(UserService);

  updateName() {
    // This will trigger an update everywhere the user is displayed
    this.userService.setUser({ id: 1, name: 'Alex', role: 'admin' });
  }
}

The HTML (`profile.component.html`)

Notice the parentheses ()—this is how you "read" a signal in the template.

HTML

<div *ngIf="userService.currentUser() as user; else guest">
  <h1>Welcome, {{ user.name }}!</h1>
  <p *ngIf="userService.isAdmin()">You have Admin permissions.</p>
</div>

<ng-template #guest>
  <button (click)="updateName()">Log In as Admin</button>
</ng-template>

Key Advantages for Your Project

No Memory Leaks: Unlike Observables, you don't need to worry about .unsubscribe().
Cleaner Templates: No more | async pipes everywhere.
Performance: Angular doesn't have to guess what changed; the Signal tells it directly.

Summary of the "Complete Skeleton" so far:

Installation: Standard Angular CLI.
Architecture: Core (logic), Shared (UI), Features (pages).
Communication: Centralized ApiService with an AuthInterceptor.
UI: Reusable components using ng-content.
State: Reactive data flow using Signals.

Now that we have our Signals managing user state, we need to lock the doors. Route Guards ensure that only authorized users can access specific parts of your application (like a /dashboard or /admin panel).

In modern Angular, we use Functional Guards, which are much leaner than the old class-based guards.

Creating the Auth Guard (`core/guards/auth.guard.ts`)

This guard will check our UserService signal. If a user isn't logged in, it kicks them back to the login page.

TypeScript

import { inject } from '@angular/core';
import { Router, CanActivateFn } from '@angular/router';
import { UserService } from '../services/user.service';

export const authGuard: CanActivateFn = (route, state) => {
  const userService = inject(UserService);
  const router = inject(Router);

  // Check the signal value
  if (userService.currentUser()) {
    return true; // Door is open
  }

  // Door is locked, redirect to login
  return router.parseUrl('/login');
};

Creating an Admin Guard

Since we already created an isAdmin computed signal in the previous step, creating a role-based guard is incredibly simple:

TypeScript

export const adminGuard: CanActivateFn = () => {
  const userService = inject(UserService);
  const router = inject(Router);

  return userService.isAdmin() ? true : router.parseUrl('/unauthorized');
};

Applying Guards to the Skeleton (`app.routes.ts`)

You define which routes are protected directly in your routing configuration. This keeps your security logic centralized.

TypeScript

import { Routes } from '@angular/router';
import { authGuard } from './core/guards/auth.guard';
import { adminGuard } from './core/guards/admin.guard';

export const routes: Routes = [
  { path: 'login', component: () => import('./features/login/login.component').then(m => m.LoginComponent) },
  
  // Protected Routes
  { 
    path: 'dashboard', 
    canActivate: [authGuard],
    loadComponent: () => import('./features/dashboard/dashboard.component').then(m => m.DashboardComponent)
  },
  { 
    path: 'admin', 
    canActivate: [authGuard, adminGuard], // Must be logged in AND an admin
    loadComponent: () => import('./features/admin/admin.component').then(m => m.AdminComponent)
  },

  { path: '', redirectTo: '/dashboard', pathMatch: 'full' }
];

Why this matters for your Project Structure

By using Functional Guards and Lazy Loading (loadComponent), your skeleton becomes highly optimized:

Security: Users can't "accidentally" stumble into private views.
Performance: The code for the /admin page isn't even downloaded by the browser unless the user passes the guards.
Readability: Your app.routes.ts acts as a clear map of your app's permissions.

The Final "Big Picture"

You now have a production-ready skeleton:

Core: Global logic, API calls, and Security (Guards/Interceptors).
Shared: Reusable UI pieces (Modals/Signals).
Features: Isolated modules for your business logic.
Routing: Secure, lazy-loaded pathways.

A professional README.md is the "handshake" of your project. It helps other developers (and your future self) understand the architecture without digging through hundreds of files.

Here is a template tailored specifically to the Signals-based, Modular Skeleton we just built.

🚀 Professional Angular Skeleton

This project is a high-performance, scalable Angular application built with v17+ Standalone Components, Signals for state management, and a Modular Core/Shared/Feature architecture.

State Management: Angular Signals for reactive, zone-less performance.
Styling: SCSS / [Tailwind CSS] for utility-first design.
Security: Functional Route Guards and JWT Interceptors.

🚀 Getting Started

Prerequisites

Node.js (LTS)
Angular CLI: npm install -g @angular/cli

Installation

Clone the repo: git clone <repository-url>
Install dependencies: npm install
Start dev server: ng serve
Navigate to http://localhost:4200/

🏗️ Development Guidelines

Creating a New Feature

Always use lazy loading for new features. Generate components within the features/ folder: ng generate component features/my-new-feature

State Management

Use the UserService pattern. Avoid local state sprawl; if data is shared across components, use a Signal in a Core service.

Shared Components

When building a shared component, use Content Projection (<ng-content>) to ensure maximum reusability.

📝 Best Practices

Strict Typing: Always define interfaces for API responses.
Clean Code: Run npm run lint before committing.
Testing: Write .spec.ts files for logic-heavy services.

How to use this template:

Create a file named README.md in your project root.
Paste the content above.
Replace placeholders like <repository-url> with your actual data.

Since you're aiming for a production-ready setup, adding Unit Tests for your Signal-based services is the final piece of the puzzle. Testing Signals is slightly different from testing traditional variables because you want to ensure the "reactivity" (the automatic updates) is working correctly.

Testing the Signal Service (`user.service.spec.ts`)

Testing a service with Signals is straightforward because you don't have to deal with complex asynchronous subscribe blocks in many cases.

TypeScript

import { TestBed } from '@angular/core/testing';
import { UserService, User } from './user.service';

describe('UserService', () => {
  let service: UserService;
  const mockUser: User = { id: 1, name: 'John Doe', role: 'admin' };

  beforeEach(() => {
    TestBed.configureTestingModule({});
    service = TestBed.inject(UserService);
  });

  it('should initialize with a null user', () => {
    expect(service.currentUser()).toBeNull();
  });

  it('should update the user signal when setUser is called', () => {
    service.setUser(mockUser);
    expect(service.currentUser()).toEqual(mockUser);
  });

  it('should correctly compute isAdmin status', () => {
    service.setUser(mockUser);
    expect(service.isAdmin()).toBeTrue();

    service.setUser({ id: 2, name: 'Jane', role: 'user' });
    expect(service.isAdmin()).toBeFalse();
  });

  it('should clear the user on clearUser', () => {
    service.setUser(mockUser);
    service.clearUser();
    expect(service.currentUser()).toBeNull();
  });
});

Testing Component Interaction with Signals

When testing components that use your shared signals, you want to verify that the DOM updates when the signal changes.

TypeScript

it('should display the username when a user is logged in', () => {
  const userService = TestBed.inject(UserService);
  userService.setUser({ id: 1, name: 'Angular Expert', role: 'user' });
  
  // Trigger change detection to update the view
  fixture.detectChanges(); 

  const compiled = fixture.nativeElement as HTMLElement;
  expect(compiled.querySelector('h1')?.textContent).toContain('Welcome, Angular Expert');
});

The Continuous Integration (CI) Layer

To make this "Skeleton" truly complete, you should automate these tests. In your package.json, you already have scripts, but you can refine them for your CI/CD pipeline (like GitHub Actions or GitLab CI).

Script	Purpose
`npm test`	Runs the test suite in "watch" mode (local dev).
`ng test --watch=false --browsers=ChromeHeadless`	Runs tests once for CI/CD pipelines.
`ng build --configuration production`	Compiles the app for the web server.

Final Skeleton Architecture Overview

At this point, you have successfully built:

A Modular Directory (Core, Shared, Features).
Global Plumbing (ApiService & Auth Interceptors).
State Management (Signals for fast, reactive data).
Security (Functional Route Guards).
Reusability (Shared Modals with Content Projection).
Documentation & Quality (README and Unit Tests).

To wrap this up, we’ll move from the code editor to the Deployment & Operations phase. A professional skeleton isn't truly "complete" until it can be built, containerized, and deployed reliably.

Containerization with Docker

Dockerizing your Angular app ensures that it runs exactly the same way in production as it does on your machine. We use a multi-stage build: one stage to build the app and another to serve it using Nginx.

Create a Dockerfile in your root directory:

Dockerfile

# Stage 1: Build
FROM node:20-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build --configuration=production

# Stage 2: Serve
FROM nginx:stable-alpine
COPY --from=build /app/dist/my-awesome-app/browser /usr/share/nginx/html
# Copy custom nginx config if needed (for handling SPA routing)
# COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

CI/CD Pipeline (GitHub Actions Example)

Automating your "Skeleton" ensures that every time you push code, your tests run and your build doesn't break.

Create .github/workflows/main.yml:

YAML

name: Angular CI/CD

on:
  push:
    branches: [ main ]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Install Dependencies
        run: npm ci
      - name: Lint
        run: npm run lint
      - name: Run Unit Tests
        run: npx ng test --watch=false --browsers=ChromeHeadless
      - name: Build Project
        run: npm run build

Final Skeleton Review Checklist

Before you start coding your business logic, verify your "Mansion" is ready:

[ ] Type Safety: Interfaces defined for all API models.
[ ] Environment Secrets: API keys moved to environment.ts (and .env for CI).
[ ] Error Handling: A global HttpInterceptor to catch and toast server errors.
[ ] Scannability: Folder structure follows the Core/Shared/Feature pattern.
[ ] Performance: Signals used for UI state; Lazy loading used for all routes.

🏁 The Complete Architectural Vision

You now have a blueprint that balances Modern Features (Signals, Standalone Components) with Industry Standards (Interceptors, Guards, Docker).

Summary of what we built:

Project Core: Centralized API services and Auth logic.
Shared UI: Reusable components like Modals with content projection.
State Layer: High-performance Signals for global reactivity.
Security Layer: Functional Route Guards.
Quality Layer: Unit tests and automated CI/CD configurations.

You’re all set! Your skeleton is robust enough to handle everything from a small MVP to a massive enterprise application.

Since you’re ready to put the first "tenant" into this mansion, let’s build a User Dashboard Feature. This will pull together everything we’ve built: the ApiService, Signals, Shared Modals, and Route Guards.

Generate the Feature Component

We’ll create a standalone dashboard component. ng generate component features/dashboard --standalone

The Logic: Combining Signals and API Calls

In the logic below, we’ll use our ApiService to fetch data and store it in a local Signal.

dashboard.component.ts

TypeScript

import { Component, OnInit, inject, signal } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ApiService } from '../../core/services/api.service';
import { ModalComponent } from '../../shared/components/modal/modal.component';

@Component({
  selector: 'app-dashboard',
  standalone: true,
  imports: [CommonModule, ModalComponent], // Import our Shared Modal
  templateUrl: './dashboard.component.html'
})
export class DashboardComponent implements OnInit {
  private api = inject(ApiService);
  
  // Local signals for UI state
  stats = signal<any>(null);
  isLoading = signal(false);
  isDetailModalOpen = signal(false);

  ngOnInit() {
    this.loadStats();
  }

  loadStats() {
    this.isLoading.set(true);
    this.api.get<any>('/user/stats').subscribe({
      next: (data) => {
        this.stats.set(data);
        this.isLoading.set(false);
      },
      error: () => this.isLoading.set(false)
    });
  }
}

The Template: Clean and Declarative

Using our shared modal and the Signal's getter syntax () makes the template very readable.

dashboard.component.html

HTML

<div class="dashboard-container">
  <h1>Your Overview</h1>

  <div *ngIf="isLoading()">
    <p>Crunching the numbers...</p>
  </div>

  <div *ng砌f="stats() as data" class="stats-grid">
    <div class="card">
      <h3>Total Projects</h3>
      <p>{{ data.projectCount }}</p>
      <button (click)="isDetailModalOpen.set(true)">View Details</button>
    </div>
  </div>

  <app-modal 
    [isOpen]="isDetailModalOpen()" 
    [title]="'Project Deep Dive'"
    (close)="isDetailModalOpen.set(false)">
    
    <p>Detailed breakdown of your project performance goes here.</p>
    <ul>
      <li *ngFor="let item of stats()?.details">{{ item.name }}: {{ item.value }}</li>
    </ul>
  </app-modal>
</div>

Final Verification: The Request Lifecycle

Now, when this feature runs:

Router checks the authGuard.
Component initializes and triggers loadStats().
ApiService sends the request.
AuthInterceptor automatically attaches the JWT token.
Signal updates the UI instantly once the data arrives.

🚀 The Finish Line

You have officially transitioned from a blank folder to a fully-architected Angular ecosystem. You have:

Infrastructure: Docker, CI/CD, and professional README.
Core Logic: Interceptors, Guards, and Global Services.
Shared Assets: Reusable UI components.
Modern State: Signal-driven data flow.

Since we’ve laid the foundation, here is the Final Handover Checklist to help you decide which path to take based on your project's specific needs:

🟢 Path A: The "Content-Heavy" App (SEO Focus)

If you are building a blog, a store, or a public-facing site:

Next Step: Ensure Angular Universal (SSR) is configured.
Action: Check your server.ts file and ensure your meta-tags are updated dynamically using the Meta and Title services.

🔵 Path B: The "Enterprise" App (Complexity Focus)

If you have hundreds of forms, complex permissions, and massive data:

Next Step: Implement Reactive Forms with custom validators.
Action: Create a FormService in your shared folder to handle reusable validation error messages.

🟡 Path C: The "Real-Time" App (Data Focus)

If you are building a chat app, a stock tracker, or a collaborative tool:

Next Step: Integrate WebSockets or Firebase.
Action: Add a SocketService to the core folder that converts stream events into Signals.

The Final "Big Picture" Architecture

Layer	Responsibility	Technology
Presentation	What the user sees and clicks	Standalone Components + Signals
Shared	Visual consistency	Reusable UI + Content Projection
Business	Logic and data transformation	Feature Services
Core	Security, Networking, State	Interceptors, Guards, Global Signals
Infrastructure	Deployment and Scalability	Docker + Nginx + CI/CD

Pro-Tip: As your project grows, keep an eye on your bundle size. Use webpack-bundle-analyzer occasionally to make sure your "Shared" folder hasn't become a "Junk Drawer" that slows down your initial load.
