angular-best-practices

Modern Angular best practices for building performant, maintainable Angular 17+ applications. Covers Signals, RxJS, components, templates, styles, performance, SSR, testing, forms, routing, accessibility, and architecture — with code examples and impact ratings for every rule. Use this skill whenever the user is working on Angular code of any kind: components, services, templates, stylesheets, routes, tests, or configuration. This applies to editing .component.ts, .service.ts, .html templates, .scss/.css styles, .spec.ts tests, .routes.ts files, store files, and any general .ts file in an Angular project. Look for angular.json, nx.json, or @angular/core imports as project indicators. Do not use for AngularJS (1.x), React, Vue, or non-Angular TypeScript projects.

Angular Material and CDK best practices. Covers selective imports, M3 theming, CDK utilities, and component test harnesses. Activates when working with @angular/material and @angular/cdk. Do not use for PrimeNG, Spartan UI, or other component libraries. Install alongside angular-best-practices for full coverage.

NgRx state management best practices for Angular. Covers pure reducers, action groups, entity adapter, selectors, and signal-based selection. Activates when working with @ngrx/store, @ngrx/effects, and @ngrx/entity. Do not use for Akita, NGXS, or standalone signal-based state. Install alongside angular-best-practices for full coverage.

PrimeNG best practices for Angular. Covers tree-shaking imports, lazy-loaded tables, and the Aura/Lara theme system with design tokens. Activates when working with primeng components. Do not use for Angular Material, Spartan UI, or other component libraries. Install alongside angular-best-practices for full coverage.

NgRx SignalStore best practices for Angular. Covers shared state, computed state, entity management, and RxJS integration with rxMethod. Activates when working with @ngrx/signals and @ngrx/signals/entities. Do not use for NgRx Store or class-based state services. Install alongside angular-best-practices for full coverage.

Spartan UI (shadcn for Angular) best practices. Covers Brain/Helm architecture, Tailwind integration, and accessible headless components. Activates when working with @spartan-ng/brain and @spartan-ng/ui. Do not use for Angular Material, PrimeNG, or other component libraries. Install alongside angular-best-practices for full coverage.

TanStack Query best practices for Angular. Covers query/mutation patterns, cache invalidation, and query key factories for server state management. Activates when working with @tanstack/angular-query-experimental. Do not use for NgRx Effects, manual HTTP caching, or RxJS-based server state. Install alongside angular-best-practices for full coverage.

Transloco i18n best practices for Angular. Covers runtime translation, lazy-loaded translation files per route, and test mocking. Activates when working with @jsverse/transloco. Do not use for ngx-translate or i18next. Install alongside angular-best-practices for full coverage.
