RIBs - Uber's new mobile architecture that scales to hundreds of engineers
summary
Uber replaces its fragile, view‑centric app with a state‑tree architecture called RIBs, RIBs = Router Interactor Builder (+Presenter, View), open‑sourced as a Java framework and used to rewrite the rider app with ~200 engineers in three months. It breaks the app into ~600 small ribs (most <300 LOC), adds dependency scopes, automatic monitoring, and pluginable features, yields near four nines reliability, almost full business‑logic test coverage, and simplifies animations and state transitions so large teams can ship without massive view controllers or tangled state machines.
