angular-21

What problem does it solve?

Angular developers often struggle to adopt modern patterns like Signals and standalone components, leading to boilerplate and inconsistent state management. This Skill teaches Angular 21 patterns to streamline component design and reactivity with signals, resource handling, and DI improvements.

Core Features & Use Cases

• Signals for state management (signal, computed, effect, linkedSignal) to create reactive components without manual subscriptions.
• Standalone components by default, eliminating the need for NgModules and simplifying component composition.
• New control flow constructs (@if, @for, @switch, @defer) for streamlined templating and performance.
• Signal-based inputs/outputs/queries (input, output, model, viewChild, inject) for type-safe, declarative APIs.
• Resource API (resource, httpResource) for declarative async data fetching and reactive data handling.
• Dependency injection with inject() in field initializers for tree-shakable, boilerplate-free DI.
• OnPush change detection to maximize performance in reactive apps.
