What is BFF?
The Backend for Frontend (BFF) design pattern involves creating a backend service layer specifically tailored to the requirements of a particular frontend application or a set of closely related frontends. While traditionally this approach has been contrasted with a monolithic backend serving multiple frontends, it’s worth noting that a BFF can indeed serve multiple frontends, especially when tools like GraphQL (GQL) are utilized. The key is that these frontends have similar requirements and data needs. Regardless of the number of frontends, the primary advantage of the BFF is its ability to be optimized for the specific needs and context of its consumer(s).
