Server-Driven UI (SDUI) is a design pattern that aims to push business logic from the client side to the server, allowing for more efficient and scalable development. By moving business logic to the server, developers can reduce the amount of code on the client-side and make updates easier to manage across multiple apps. This approach requires synchronization between backend and frontend teams but can lead to a better experience for users as it adapts to their needs throughout their journey. The use of GraphQL and Server-Driven UI enables developers to control what components are used, in what order they are rendered, and to make updates immediately without requiring coordination across multiple teams or code bases.
