React Server Components: Untangling Frontend Data Fetching

This article explores how React Server Components solve the complexities of frontend data fetching. Traditional REST APIs struggle to keep up with evolving UI needs, leading to either data redundancy or insufficient data. The author proposes a BFF (Backend for Frontend) approach, introducing the ViewModel concept to the backend, allowing the server to directly return the specific data each component requires. By decomposing ViewModel functions into smaller units and leveraging JSX, a tight coupling between components and data loading logic is achieved, resulting in an efficient and maintainable frontend architecture. This method is similar in spirit to Async XHP, seamlessly integrating data fetching and UI rendering, but avoids the limitations of traditional XHP in highly interactive applications.
