Creating nested components is fundamental for building scalable and maintainable Angular applications with proper component hierarchy. As the creator of CoreUI, a widely used open-source UI library, I’ve architected complex component structures in Angular applications over 25 years of development. From my expertise, the most effective approach is to use component selectors within templates and establish clear parent-child communication patterns. This creates reusable, modular components that follow Angular’s component-based architecture principles.

Lifting state up in React involves moving shared state from child components to their nearest common ancestor, enabling proper data flow and communication between sibling components. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented state lifting patterns in thousands of React applications for dashboard filters, form management, and component synchronization. From my expertise, the most effective approach is identifying shared state needs and moving state to the closest common parent with callback props for updates. This method provides centralized state management and clear data flow throughout the component hierarchy.

Creating a shared module in Angular allows you to organize common components, directives, and pipes that multiple feature modules can reuse, reducing code duplication and improving maintainability. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented shared modules in countless Angular applications to manage reusable UI components and services across enterprise applications. From my expertise, the most effective approach is creating a dedicated SharedModule that exports common components and imports essential Angular modules. This method provides centralized component management and consistent imports across feature modules.
