Managing module imports and exports is fundamental for organizing Angular applications into reusable, maintainable pieces and creating component libraries. As the creator of CoreUI, a widely used open-source UI library, I’ve architected modular Angular applications and component libraries over 25 years of development. From my expertise, the most effective approach is using the imports array to bring in external modules and the exports array to make components available to other modules. This creates a clean modular architecture that promotes code reuse and maintainability.
