Architecture

edit file

Our aim is to take advantage of multiplatform features as much as possible, specially Compose Multiplatform. Platform specific modules will be limited to the minimum required to setup and launch the apps with a compose wrapper, besides platform-specific code that we can’t avoid, such as the loading our pre-compiled engine.

Principals

• Dependency Inversion
• Unidirectional Data Flow
• Model-View-ViewModel

Main module structure

• engine the Oonimkall engine abstraction in kotlin

• probe our Probe app code

  • background shared code ran on background tasks
  • config configurations for each platform (Android, iOS), organization (OONI, DW) and flavor (full, F-droid)
  • di dependency injection
  • shared classes and methods shared across the whole app
  • data data layer code (database, preferences, network…)
  • ui UI layer code, organized into features/screens
