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.
