Architecture Overview

ComposeTemplate separates app composition, shared infrastructure, product features, build logic, and performance tooling.

App module

The app module is the composition root. It connects feature modules, configures app-level setup, owns application id/namespace, and should not contain business logic.

Core modules

core/* modules provide reusable infrastructure: common result types, data, database, network, secrets, security, UI, navigation, analytics, config, permissions, and Google Play integrations.

Feature modules

Each feature is split into four Gradle modules:

feature/{name}/
├── data
├── domain
├── navigation
└── presentation

Dependency direction

data → domain ← presentation
navigation → core:navigation
presentation → navigation

The domain layer should not know data or presentation implementation details.
