core

Entities that are passed around between layers.

domain

Datasource apis (interfaces). Interactors also live here. Interactors are the single-use classes that operate at the boundaries of different layers.

presentation

Redux, basically. Redux is our chosen architecture for managing the data flow from users to the network, and from the network back to the user. https://medium.com/groupon-eng/grox-the-art-of-the-state-b5223f48d696

Our Redux implementation breaks apart the Epic (asynchronous behaviors) and Reducer (pure functions for updating state). This module also contains Selectors, which are the pure functions used to take State and transform it into what various frontends (e.g. Android) use.

data

API model classes, implementations of domain datasources, Retrofit Service interfaces,

android

The Android specific UI bindings. Think Activity, View, etc.
