I really like the BFF pattern as it can solve a lot of problems. That said, I've always found it quite complicated to build BFFs because there was no such thing as a "BFF Framework", which was one of the reasons we've built WunderGraph. One of the core use cases is to make building BFFs easy and solve a lot of cross cutting concerns. The idea is that you don't really "write" a BFF but rather generate most of it by treating APIs (origins) as dependencies. I'd love to hear what you think about this approach on implementing the BFF pattern:
