Compose Sample

A project template with the following objectives in mind:

• use modern UI tools
• use a single source of truth
• make it painless to write new features
• optimized for incremental build

Technical stack

• arch:
  • app: clean architecture with features x layer modularization
  • ui: simplified MVI
• build: kts gradle build scripts + gradle convention plugins to simplify + version catalog
• dep injection: hilt + auto-dagger
• ui: compose + material3 + navigation3
• async: coroutines & flow
• db: room
• rest: retrofit
• annotation processing: ksp only, no kapt

App structure

Modules hierarchy:

• app
• core
  • di
  • feature
    • nav
    • ui
  • ui
    • theme
• features
  • overview
    • nav
    • ui
  • library
    • data
    • domain
    • nav
    • ui
• gradle-plugins

Feature module plugins:

• app.feature.data
• app.feature.domain
• app.feature.nav
• app.feature.ui

Each adds all requirements for the module of a given layer, save the android namespace.

Navigation is using dedicated modules for stronger feature isolation.

Future

• doc:
  • document appInit task
  • document features creation
• unit tests
• room: migration handling
• di: investigate moving from hilt+autodagger to metro once it gets more mature
