Grox: a library to manage the state of Java / Android apps
summary
Grox is an open source Java/Kotlin library (https://github.com/groupon/grox) that Groupon builds into production to tame concurrent app state: a single store holds immutable state, a Rx-enabled command layer turns UI events into streams of actions, and middleware enables logging and time‑travel debugging. It claims scalability across multiple teams, recommends actions are pure reducers, uses RxJava/RxBinding for wiring, and leaves persistence or scoping choices to the app.
