🏛 Architecture

Alkaa architecture is strongly based on the Hexagonal Architecture by Alistair Cockburn. The application also relies heavily in modularization for better separation of concerns and encapsulation.

Let's take a look in each major module of the application:

  • app - The Application module. It contains all the initialization logic for the Android environment and starts the Jetpack Navigation Compose Graph.
  • features - The module/folder containing all the features (visual or not) from the application
  • domain - The modules containing the most important part of the application: the business logic. This module depends only on itself and all interaction it does is via dependency inversion.
  • data - The module containing the data (local, remote, light etc) from the app

This type of architecture protects the most important modules in the app. To achieve this, all the dependency points to the center, and the modules are organized in a way that the more the module is in the center, more important it is.

To better represents the idea behind the modules, here is a architecture image representing the flow of dependency:
