Short answer: Unsubscribe from Observables using: takeUntil with a destroy notifier. async pipe which auto-unsubscribes. Remove event listeners added manually. Avoid retaining references to DOM or large objects. Use tools like Chrome DevTools and Angular Profiler.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.
