Accessing child components and DOM elements directly is essential for building interactive Angular applications that require programmatic control over child elements. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented complex component interactions using ViewChild across hundreds of Angular components over 25 years of development. From my expertise, the most reliable approach is using the @ViewChild decorator to get a reference to child components or template elements. This enables direct method calls, property access, and DOM manipulation when needed.

Using the @Input decorator is fundamental for creating reusable Angular components that accept data from parent components and establish proper data flow patterns. As the creator of CoreUI, a widely used open-source UI library, I’ve designed thousands of Angular components using @Input decorators for flexible customization, configuration options, and data binding in enterprise component libraries. From my expertise, the most robust approach is to use @Input decorator with TypeScript typing and proper validation. This method provides type safety, clear component interfaces, and excellent developer experience while maintaining backward compatibility and component reusability.
