analogjs/directivas-angular

Crea directivas personalizadas en Angular v20+ para manipulación del DOM y extensión de comportamiento.

¿Qué es directivas-angular?

Esta skill permite crear directivas personalizadas en Angular v20+ para manipular el DOM y extender el comportamiento de los elementos. Incluye directivas de atributo (que modifican apariencia o comportamiento), directivas estructurales (ideales para portales, superposiciones y elementos condicionales) y directivas huésped (para componer comportamientos entre componentes). Se activa cuando necesitas crear comportamientos reutilizables del DOM, extender la funcionalidad de un elemento o combinar comportamientos de varios componentes. Es importante usar directivas estructurales nativas (@if, @for, @switch) para flujos de control simples en lugar de crear directivas estructurales personalizadas. Compatible con Angular CLI y proyectos que usan Angular v20 o superior.

¿Qué hace directivas-angular?

Crea directivas personalizadas en Angular v20+ para manipulación del DOM y extensión de comportamiento. Úsalas para directivas de atributo que modifican el comportamiento/apariencia de elementos, directivas estructurales para portales/overlays y directivas huésped para composición. Se activa al crear comportamientos reutilizables del DOM, extender la funcionalidad de elementos o componer comportamientos entre componentes. Nota: usa las directivas nativas @if/@for/@switch para flujo de control, no directivas estructurales personalizadas.

Individual skills in this repo

This repo contains 9 individual skills — each has its own dedicated page.

analogjs/angular-component

Create modern Angular standalone components following v20+ best practices. Use for building UI components with signal-based inputs/outputs, OnPush change detection, host bindings, content projection, and lifecycle hooks. Triggers on component creation, refactoring class-based inputs to signals, adding host bindings, or implementing accessible interactive components.

analogjs/angular-di

Implement dependency injection in Angular v20+ using inject(), injection tokens, and provider configuration. Use for service architecture, providing dependencies at different levels, creating injectable tokens, and managing singleton vs scoped services. Triggers on service creation, configuring providers, using injection tokens, or understanding DI hierarchy.

analogjs/angular-forms

Build signal-based forms in Angular v21+ using the new Signal Forms API. Use for form creation with automatic two-way binding, schema-based validation, field state management, and dynamic forms. Triggers on form implementation, adding validation, creating multi-step forms, or building forms with conditional fields. Signal Forms are experimental but recommended for new Angular projects. Don't use for template-driven forms without signals or third-party form libraries like Formly or ngx-formly.

analogjs/angular-http

Implement HTTP data fetching in Angular v20+ using resource(), httpResource(), and HttpClient. Use for API calls, data loading with signals, request/response handling, and interceptors. Triggers on data fetching, API integration, loading states, error handling, or converting Observable-based HTTP to signal-based patterns.

analogjs/angular-routing

Implement routing in Angular v20+ applications with lazy loading, functional guards, resolvers, and route parameters. Use for navigation setup, protected routes, route-based data loading, and nested routing. Triggers on route configuration, adding authentication guards, implementing lazy loading, or reading route parameters with signals.

analogjs/angular-signals

Implement signal-based reactive state management in Angular v20+. Use for creating reactive state with signal(), derived state with computed(), dependent state with linkedSignal(), and side effects with effect(). Triggers on state management questions, converting from BehaviorSubject/Observable patterns to signals, or implementing reactive data flows.

analogjs/angular-ssr

Implement server-side rendering and hydration in Angular v20+ using @angular/ssr. Use for SSR setup, hydration strategies, prerendering static pages, and handling browser-only APIs. Triggers on SSR configuration, fixing hydration mismatches, prerendering routes, or making code SSR-compatible.

analogjs/angular-testing

Write unit and integration tests for Angular v20+ applications using Vitest or Jasmine with TestBed and modern testing patterns. Use for testing components with signals, OnPush change detection, services with inject(), and HTTP interactions. Triggers on test creation, testing signal-based components, mocking dependencies, or setting up test infrastructure. Don't use for E2E testing with Cypress or Playwright, or for testing non-Angular JavaScript/TypeScript code.

analogjs/angular-tooling

Use Angular CLI and development tools effectively in Angular v20+ projects. Use for project setup, code generation, building, testing, and configuration. Triggers on creating new projects, generating components/services/modules, configuring builds, running tests, or optimizing production builds. Don't use for Nx workspace commands, custom Webpack configurations, or non-Angular CLI build systems like Vite standalone or esbuild direct usage.
