How to Use Angular Architect in Claude Code for Beginners

Feb 14, 2026

Purpose

This post demonstrates how to use the Angular Architect skill in Claude Code to design and implement scalable Angular applications with proper architecture patterns.

Environment

Claude Code with claude-skills plugin
Angular 18+ (recent version)
Node.js 20+
TypeScript 5+

What is Angular Architect?

The Angular Architect skill is a specialized agent in the claude-skills ecosystem that helps you design Angular applications following best practices and established patterns. When I need to create a new Angular project, refactor existing code, or implement features, this skill guides me through architectural decisions.

I can use it for:

Project structure and module organization
Component design and communication patterns
State management strategies
Service layer architecture
Routing design
Testing strategies

Installation and Setup

First, I need to install the claude-skills plugin. I run:

npm install -g @jeffallan/claude-skills

Then I activate the Angular Architect skill in Claude Code by using the Skill command:

Skill: "angular-architect"

The skill loads and I can see it’s ready to help with Angular architecture decisions.

Core Usage Patterns

The Angular Architect skill activates when I use specific trigger phrases. I found these work well:

“Design the architecture for an Angular e-commerce application” “Review my Angular project structure” “Create a scalable Angular module layout” “Refactor this component to follow best practices”

The skill then analyzes my project and provides architectural guidance based on Angular best practices.

Practical Example: Building a Dashboard Application

When I started building a dashboard application, I invoked the skill this way:

I need to create an Angular dashboard application with:
- User authentication
- Data visualization widgets
- Admin panel
- Role-based access control

Design the architecture and module structure.

The skill analyzed my requirements and suggested:

src/
├── app/
│   ├── core/                    # Singleton services
│   │   ├── guards/
│   │   ├── interceptors/
│   │   ├── services/
│   │   │   └── auth.service.ts
│   │   └── core.module.ts
│   ├── features/                # Feature modules
│   │   ├── dashboard/
│   │   │   ├── components/
│   │   │   ├── services/
│   │   │   └── dashboard.module.ts
│   │   ├── admin/
│   │   └── widgets/
│   ├── shared/                  # Shared components
│   │   ├── components/
│   │   ├── directives/
│   │   ├── pipes/
│   │   └── shared.module.ts
│   └── app.module.ts

The skill explained the reasoning:

core/ contains singleton services that are used app-wide
features/ organizes by business domain
shared/ contains reusable UI components
Each feature module is lazy-loaded

Example: Component Communication Pattern

I needed to implement communication between a list component and detail component. The skill guided me:

// Parent component (dashboard.component.ts)
@Component({
  selector: 'app-dashboard',
  template: `
    <app-widget-list
      (widgetSelected)="onWidgetSelect($event)">
    </app-widget-list>
    <app-widget-detail
      [widgetId]="selectedWidgetId">
    </app-widget-detail>
  `
})
export class DashboardComponent {
  selectedWidgetId: string | null = null;

  onWidgetSelect(id: string) {
    this.selectedWidgetId = id;
  }
}

// List component emits events
@Component({
  selector: 'app-widget-list',
  template: `
    <div *ngFor="let widget of widgets"
         (click)="selectWidget(widget.id)">
      {{ widget.name }}
    </div>
  `
})
export class WidgetListComponent {
  @Output() widgetSelected = new EventEmitter<string>();

  selectWidget(id: string) {
    this.widgetSelected.emit(id);
  }
}

// Detail component receives input
@Component({
  selector: 'app-widget-detail',
  template: `
    <div *ngIf="widget">
      {{ widget.name }}: {{ widget.value }}
    </div>
  `
})
export class WidgetDetailComponent {
  @Input() widgetId: string | null = null;

  constructor(private widgetService: WidgetService) {}

  widget$ = this.widgetService.widgets$.pipe(
    map(widgets => widgets.find(w => w.id === this.widgetId))
  );
}

The skill recommended using:

@Output() with EventEmitter for child-to-parent
@Input() for parent-to-child
RxJS observables for async data flow
Simple data binding for direct communication

Example: Service Architecture

When I needed to design the service layer, the skill showed me:

// API service - handles HTTP
@Injectable({ providedIn: 'root' })
export class WidgetApiService {
  private http = inject(HttpClient);

  getWidgets() {
    return this.http.get<Widget[]>('/api/widgets');
  }

  getWidget(id: string) {
    return this.http.get<Widget>(`/api/widgets/${id}`);
  }
}

// Domain service - business logic
@Injectable({ providedIn: 'root' })
export class WidgetService {
  private api = inject(WidgetApiService);
  private state = signalState<WidgetState>({
    widgets: [],
    loading: false,
    error: null
  });

  readonly widgets$ = toObservable(this.state.widgets);
  readonly loading$ = toObservable(this.state.loading);

  loadWidgets() {
    this.state.setLoading(true);
    this.api.getWidgets().pipe(
      tap(widgets => this.state.setWidgets(widgets)),
      catchError(error => {
        this.state.setError(error.message);
        return of([]);
      }),
      finalize(() => this.state.setLoading(false))
    ).subscribe();
  }
}

// Interface
export interface Widget {
  id: string;
  name: string;
  value: number;
}

interface WidgetState {
  widgets: Widget[];
  loading: boolean;
  error: string | null;
}

The separation:

API service handles HTTP calls
Domain service contains business logic and state
Components consume domain services, not API services directly

Best Practices

DO

Use feature modules

Each feature gets its own module with components, services, and routing.
Lazy load features to improve initial load time.

Separate concerns

core/ - Singletons that live app-wide
features/ - Business domain modules
shared/ - Reusable UI elements

Use Signals for state

Prefer Angular Signals over RxJS for local component state.
Use RxJS for async operations and complex streams.

Implement proper typing

Define interfaces for data models.
Use strict TypeScript settings.
Avoid 'any' type.

DON’T

Don’t put everything in app.module

Wrong: Importing all components into app.module
Right: Using feature modules with lazy loading

Don’t share data via services unnecessarily

Wrong: Creating a service just to share data between components
Right: Use @Input/@Output or a proper state management solution

Don’t mix responsibilities

Wrong: Components making HTTP calls directly
Right: Components delegate to services

Don’t ignore lazy loading

Wrong: Eager loading all modules
Right: Lazy load feature modules to improve performance

How It Works

When I invoke the Angular Architect skill, it:

Analyzes my project structure and requirements
Identifies architectural patterns that fit my use case
Provides code examples following Angular best practices
Explains the reasoning behind recommendations

The skill uses knowledge from:

Angular official style guide
Community best practices
Common patterns in successful Angular applications
Performance optimization techniques

I can test the skill by describing my scenario:

I need to build an Angular application for inventory management with:
- Product listing and search
- Stock level tracking
- Supplier management
- Reporting dashboard

Design the module structure and data flow.

The skill responds with a complete architecture plan including module organization, component hierarchy, service design, and state management approach.

Summary

In this post, I showed how to use the Angular Architect skill in Claude Code to design scalable Angular applications. The key points are:

Use the skill for architectural decisions, not just code generation
Follow the core/features/shared module pattern
Separate API services from domain services
Use Angular Signals for local state, RxJS for async operations
Implement lazy loading for feature modules

The skill helps me avoid common mistakes and build applications that are maintainable and scalable.
