Angular Component

Create standalone components for Angular v20+. Components are standalone by default—do NOT set standalone: true.

Component Structure

import { Component, ChangeDetectionStrategy, input, output, computed } from '@angular/core';

@Component({
  selector: 'app-user-card',
  changeDetection: ChangeDetectionStrategy.OnPush,
  host: {
    'class': 'user-card',
    '[class.active]': 'isActive()',
    '(click)': 'handleClick()',
  },
  template: `
    <img [src]="avatarUrl()" [alt]="name() + ' avatar'" />
    <h2>{{ name() }}</h2>
    @if (showEmail()) {
      <p>{{ email() }}</p>
    }
  `,
  styles: `
    :host { display: block; }
    :host.active { border: 2px solid blue; }
  `,
})
export class UserCard {
  // Required input
  name = input.required<string>();
  
  // Optional input with default
  email = input<string>('');
  showEmail = input(false);
  
  // Input with transform
  isActive = input(false, { transform: booleanAttribute });
  
  // Computed from inputs
  avatarUrl = computed(() => `https://api.example.com/avatar/${this.name()}`);
  
  // Output
  selected = output<string>();
  
  handleClick() {
    this.selected.emit(this.name());
  }
}

Signal Inputs

// Required - must be provided by parent
name = input.required<string>();

// Optional with default value
count = input(0);

// Optional without default (undefined allowed)
label = input<string>();

// With alias for template binding
size = input('medium', { alias: 'buttonSize' });

// With transform function
disabled = input(false, { transform: booleanAttribute });
value = input(0, { transform: numberAttribute });

Signal Outputs

import { output, outputFromObservable } from '@angular/core';

// Basic output
clicked = output<void>();
selected = output<Item>();

// With alias
valueChange = output<number>({ alias: 'change' });

// From Observable (for RxJS interop)
scroll$ = new Subject<number>();
scrolled = outputFromObservable(this.scroll$);

// Emit values
this.clicked.emit();
this.selected.emit(item);

Host Bindings

Use the host object in @Component—do NOT use @HostBinding or @HostListener decorators.

@Component({
  selector: 'app-button',
  host: {
    // Static attributes
    'role': 'button',
    
    // Dynamic class bindings
    '[class.primary]': 'variant() === "primary"',
    '[class.disabled]': 'disabled()',
    
    // Dynamic style bindings
    '[style.--btn-color]': 'color()',
    
    // Attribute bindings
    '[attr.aria-disabled]': 'disabled()',
    '[attr.tabindex]': 'disabled() ? -1 : 0',
    
    // Event listeners
    '(click)': 'onClick($event)',
    '(keydown.enter)': 'onClick($event)',
    '(keydown.space)': 'onClick($event)',
  },
  template: `<ng-content />`,
})
export class Button {
  variant = input<'primary' | 'secondary'>('primary');
  disabled = input(false, { transform: booleanAttribute });
  color = input('#007bff');
  
  clicked = output<void>();
  
  onClick(event: Event) {
    if (!this.disabled()) {
      this.clicked.emit();
    }
  }
}

How to use angular-component on Cursor
AI-first code editor with Composer
1
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add angular-component
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/analogjs/angular-skills --skill angular-componentcopy
The skills CLI fetches angular-component from GitHub repository analogjs/angular-skills and configures it for Cursor.

Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│   • Amp
│   • Antigravity
│   • Cline
│   • Codex
│ ●Cursor(selected)
│   • Cursor
│   • Windsurf

Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/angular-component
Reload or restart Cursor to activate angular-component. Access the skill through slash commands (e.g., /angular-component) or your agent's skill management interface.
⚠
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
