RIBs — which is short for router, interactor and builder — is a cross-platform architecture mobile framework from Uber. The key idea of RIBs is to decouple business logic from the view tree, and thus ensure the app is driven by business logic. This is actually an application of Clean Architecture in mobile application development. By applying consistent architecture patterns across native Android and iOS, RIBs provides clear statement management and good testability. We advise putting business logic in the back-end service rather than leak it into the view, so if you do have a complicated mobile application, RIBs can help manage this complexity.
