Core Concepts

• Standalone components: default since v15, no NgModules needed
• Signals: signal(), computed(), effect() for reactive state without Zone.js
• Dependency injection: inject() function, @Injectable() providers
• RxJS integration: Observables, async pipe, operators for async workflows
• Directives: structural (ngIf, ngFor) and attribute ([ngClass], [ngStyle])

Common Patterns

• Smart + dumb component separation with @Input/@Output signals
• Lazy loading routes with loadComponent in standalone setup
• Reactive forms with FormBuilder, validators, and valueChanges
• HTTP interceptors for auth headers and error handling
• Content projection with ng-content and multi-slot projection

Best Practices

• Prefer signals over RxJS for state, keep RxJS for event streams
• Use OnPush change detection with signals for performance
• Leverage inject() rather than constructor injection
• Keep components small, delegate logic to services
• Use Angular CLI for code generation and schematics

Common Code Patterns

• Standalone component with signal-based state management
• Route guard as injectable function returning Observable/boolean
• Typed reactive form with FormGroup and validation
