Backend For Frontend
Backend For Frontend (BFF) is an architectural pattern where a dedicated backend service is created for each frontend application or user interface. It acts as an intermediary between the frontend and multiple backend microservices or APIs, aggregating data and handling client-specific logic. This approach simplifies frontend development by providing a tailored API that matches the exact needs of each client.
Developers should use BFF when building complex applications with multiple frontends (e.g., web, mobile, desktop) that interact with a microservices-based backend. It is particularly useful for optimizing performance by reducing over-fetching of data, handling client-specific transformations, and improving security by abstracting backend complexity. This pattern helps teams scale independently and deliver faster user experiences.
