Backend for Frontend (BFF)

What is a Backend for Frontend (BFF)?

A backend for frontend is a specialized backend service that is designed to cater to the specific needs of the frontend. A BFF pattern creates a dedicated backend service for each frontend application ensuring that the frontend has access to the specific data it requires without having to rely on a shared backend.

What Makes a Backend for Frontend Useful?

A backend for frontend architecture uses microservices, and in this approach, each microservice handles a specific set of functionalities or features that the frontend application requires. The BFF then acts as a gateway that coordinates and orchestrates requests from the frontend to the appropriate microservice.

By using microservices, the BFF architecture allows greater scalability and flexibility as each microservice can be developed and scaled independently. Additionally, it can help to reduce the complexity of the overall system by breaking down the functionality into smaller and more manageable components.
