analogjs/angular-testing

Rédigez des tests unitaires et d'intégration pour les applications Angular v20+ avec Vitest ou Jasmine, en utilisant TestBed et les patterns modernes.

Qu'est-ce que angular-testing ?

Cette compétence permet de générer des tests unitaires et d'intégration pour des applications Angular v20+ en utilisant les frameworks Vitest ou Jasmine avec TestBed. Elle est conçue pour tester des composants utilisant des signaux, la détection de changements OnPush, des services avec `inject()`, et des interactions HTTP. Elle s'active lors de la création de tests, du test de composants basés sur des signaux, du mock de dépendances ou de la mise en place de l'infrastructure de test. Elle est compatible avec les environnements de développement Angular modernes et ne doit pas être utilisée pour les tests E2E (Cypress, Playwright) ni pour tester du code JavaScript/TypeScript non Angular.

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-directives

Create custom directives in Angular v20+ for DOM manipulation and behavior extension. Use for attribute directives that modify element behavior/appearance, structural directives for portals/overlays, and host directives for composition. Triggers on creating reusable DOM behaviors, extending element functionality, or composing behaviors across components. Note - use native @if/@for/@switch for control flow, not custom structural directives.

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-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.
