Building reusable components is fundamental to creating maintainable and scalable React applications. As the creator of CoreUI, a widely used open-source UI library, and with over 11 years of experience in software development, I’ve designed thousands of reusable components that serve millions of developers worldwide. The key to creating truly reusable components is designing flexible APIs through props, using composition patterns, and maintaining proper abstraction levels. This approach ensures components can adapt to different use cases while remaining easy to understand and maintain.

Creating shared modules is essential for organizing reusable components, directives, and pipes that are used across multiple feature modules in Angular applications. As the creator of CoreUI, a widely used open-source UI library, I’ve architected shared module systems in countless Angular projects over 25 years of development. From my expertise, the most effective approach is using Angular CLI to generate a shared module and then importing/exporting common components. This promotes code reusability and maintains clean module architecture.
