Answer
Angular apps rely on clear communication patterns—Inputs, Outputs, services, Subjects, and facades. These prevent coupling, simplify flows, and support scalable UI structure.
Quick Answer
Component communication patterns: Parent to Child via @Input. Child to Parent via @Output EventEmitter. Sibling components via a shared service with BehaviorSubject. Distant components via NgRx Store or service state. Avoid: directly accessing child component instances (tight coupling). Good communication patterns keep components decoupled and independently testable.
