What is the 'Backend for Frontend' approach in web application development?

The article on Frankel's blog delves into the concept of Backend for Frontend (BFF). This approach allows for the creation of a dedicated backend tailored to the needs of various frontends of applications, such as web, mobile, or IoT. Frankel explains how BFF can simplify the communication process between the frontend and backend by offering specialized interfaces that are better suited to the requirements of each frontend. The article also provides examples of BFF implementation and tips for incorporating this approach into projects. This concept is gaining popularity in the software development world, as it offers engineers greater flexibility and efficiency in building applications. The use of BFF can lead to better code maintenance and more responsive user interfaces, resulting in a higher comfort level for developers and an improved experience for end-users.
