Creating reusable Vue components is fundamental for building maintainable, scalable applications with modular architecture and consistent user interfaces. As the creator of CoreUI, a widely used open-source UI library, I’ve built thousands of Vue components for buttons, forms, navigation, and complex dashboard layouts in enterprise applications. From my expertise, the most effective approach is to use Single File Components (SFC) with .vue extension. This method provides excellent developer experience by combining template, script, and style in one file while maintaining clear separation of concerns.
