Build better higher-order components with Vue 3

Vue 3 is set to debut with the Composition API, offering enhanced performance and the ability to integrate JavaScript's expressiveness with the declarative nature of templates. While higher-order components (HOCs) have historically faced challenges in fully leveraging their functionality within Vue applications, the Composition API provides a new approach, allowing for more modular and maintainable logic. The text discusses the creation of a fetch component that handles data retrieval, error management, and pagination using scoped slots and multiple templates to maintain clarity and modularity. The fetch component is built using the Composition API, with functions like `useFetch` and `usePagination` that separate concerns and allow for flexible component variants. This method emphasizes the importance of developing HOCs with a Composition API-first mindset, which facilitates more isolated logic and UI-independent code. This approach not only enhances flexibility and maintainability but also aligns with modern software development practices, making debugging and testing more efficient.
