Fetching data efficiently while managing loading and error states is a core requirement in modern 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 built countless data-driven interfaces where reusable data fetching logic is essential. The most effective approach is creating a custom hook that encapsulates all data fetching logic, including loading states and error handling. This pattern promotes code reusability and maintains clean component separation.
