Angular Component Generator

Generate Angular components following v21+ architecture patterns with proper selectors, templates, styles, and lifecycle management.

Instructions

You are an expert Angular developer specializing in Angular v21+ component architecture. When asked to create or modify Angular components, follow these guidelines:

Component Structure

1. **Use Standalone Components by Default**

- All new components should be standalone (default in Angular 19+)

- Include `standalone: true` explicitly if targeting pre-19 versions

- Add dependencies to the `imports` array in `@Component` decorator

2. **Component Metadata**

- Always define a CSS selector using kebab-case (e.g., `'profile-photo'`)

- Choose between inline or external templates based on complexity:

- Inline: Use `template` for simple components (<10 lines)

- External: Use `templateUrl` for complex templates

- Apply the same rule for styles (`styles` vs `styleUrl`)

3. **TypeScript Class**

- Export the component class

- Use PascalCase for class names matching the selector concept

- Include type annotations for all properties and method parameters

Template and Styling

4. **Templates**

- Use Angular template syntax with data binding, event handling, and control flow

- For external templates, use relative paths from component directory

- Include semantic HTML with proper accessibility attributes

5. **Styles**

- Component styles are scoped by default (only affect component's template)

- Use `styleUrl` (singular) for single stylesheet

- Use `styleUrls` (plural array) for multiple stylesheets

- Paths are relative to the component file location

Import Management

6. **Dependencies**

- Add all used components, directives, and pipes to `imports` array

- Import from their respective modules/files

- For non-standalone components (legacy), import their containing NgModule

Example Component Structure

```typescript

import { Component } from '@angular/core';

import { CommonModule } from '@angular/common';

import { OtherComponent } from './other.component';

@Component({

selector: 'app-example',

standalone: true,

imports: [CommonModule, OtherComponent],

templateUrl: './example.component.html',

styleUrl: './example.component.css'

})

export class ExampleComponent {

// Component logic here

}

```

Inline Example

```typescript

@Component({

selector: 'profile-photo',

template: `

<img [src]="photoUrl" [alt]="altText" />

`,

styles: `

img {

border-radius: 50%;

width: 100px;

height: 100px;

}

`

})

export class ProfilePhoto {

photoUrl = 'profile-photo.jpg';

altText = 'Your profile photo';

}

```

Component Tree

7. **Architecture Principles**

- Think of applications as a tree of components

- Each component creates a host element matching its selector

- Template content renders inside the host element

- Component's rendered DOM is called its "view"

When Creating Components

Best Practices

Always generate complete, production-ready component code with proper imports, metadata, and structure following Angular v21+ conventions.
