+### DI Structure +- `PlatformSDK` — global Kodein DI container (singleton, initialized at app startup) +- `Inject.instance()` — service locator shorthand +- Feature modules: `DailyModule`, `DetailModule`, `HabitModule`, `ProjectModule`, `SettingsModule`, `TrackerModule` +- Platform modules: `CoreModule`, `DatabaseModule`, `FeatureModule`, `SerializationModule` + +## Target Architecture + +### Decompose Component Hierarchy + +``` +RootComponent (Child Stack) +├── SplashComponent +├── MainComponent (manages bottom nav) +│ └── Per-tab Child Stacks: +│ ├── DailyComponent (Child Stack) +│ │ ├── DailyListComponent +│ │ └── DetailComponent(habitId) +│ ├── HealthComponent (Child Stack) +│ │ ├── HealthListComponent +│ │ ├── TrackHabitComponent(habitId) +│ │ └── CreateHabitComponent(type?) +│ ├── StatisticsComponent (leaf) +│ ├── ChatComponent (leaf) +│ └── ProfileComponent (Child Stack) +│ ├── ProfileStartComponent +│ ├── SettingsComponent +│ ├── EditProfileComponent +│ └── ProjectListComponent +└── CreateHabitFlowComponent (from root-level create route) +``` + +### Component Base Pattern + +Each component will: +- Implement `ComponentContext` by delegation +- Implement `DIAware` to receive Kodein DI from parent +- Use `Value` for observable state +- Use `coroutineScope(Dispatchers.Main)` from Essenty for async work +- Expose an `onEvent(Event)` method for UI interaction (or direct methods) +- Use sealed class `Config` with `@Serializable` for navigation configurations + +### Example Component (DailyListComponent) + +```kotlin +class DailyListComponent( + componentContext: ComponentContext, + override val di: DI, + private val onHabitSelected: (String) -> Unit, + private val onComposeClicked: () -> Unit +) : ComponentContext by componentContext, DIAware { + + private val getHabitsForTodayUseCase: GetHabitsForTodayUseCase by di.instance() + private val switchHabitUseCase: SwitchHabitUseCase by di.instance() + + private val scope = coroutineScope(Dispatchers.Main) + + private val _state = MutableValue(DailyViewState()) + val state: Value = _state + + fun onEvent(event: DailyEvent) { ... } +} +``` + +### Navigation Config Pattern + +```kotlin +@Serializable +sealed class RootConfig { + @Serializable data object Splash : RootConfig() + @Serializable data object Main : RootConfig() + @Serializable data object Create : RootConfig() +} +``` + +## Files to Create + +| File | Purpose | +|------|---------| +| `composeApp/src/commonMain/kotlin/root/RootComponent.kt` | Root component

locator no longer needed | +| Legacy ViewModels in `screens/` package (if unused) | Cleanup | + +## Detailed Implementation Approach + +### Phase 1: Add Dependencies +1. Add to `libs.versions.toml`: + - `decompose = "3.2.0"` (or latest stable) + - `essenty = "2.2.0"` (or compatible version) + - Library entries for `decompose`, `decompose-compose`, `essenty-lifecycle-coroutines` +2. Update `build.gradle.kts`: + - Add Decompose and Essenty dependencies to `commonMain` + - Keep `compose-navigation` and `compose-viewmodel` temporarily during migration + - Add `kotlinx-serialization` plugin if not already applied (needed for `@Serializable` configs) + +### Phase 2: Create Root Component Infrastructure +1. Create `RootComponent` with `Child Stack` managing Splash/Main/Create +2. Create `RootContent.kt` composable that renders the stack using `Children` +3. Create `SplashComponent` (simple component that triggers navigation to Main) + +### Phase 3: Create Main Component with Bottom Nav +1. Create `MainComponent` managing 5 tab stacks +2. Each tab is a separate `Child Stack` (using `childStack` with different keys) +3. Create `MainContent.kt` with `BottomNavigation` rendering active tab's stack +4. Tab icons/titles from existing `AppScreens` enum (preserve in MainComponent) + +### Phase 4: Migrate Each Feature's ViewModel → Component +For each ViewModel: +1. Create corresponding Component class implementing `ComponentContext by componentContext` and `DIAware` +2. Replace `Inject.instance()` with `by di.instance()` +3. Replace `viewModelScope` with Essenty `coroutineScope(Dispatchers.Main)` +4. Replace `MutableStateFlow` with `MutableValue` / `Value` +5. Replace `SharedFlow` with callback lambdas passed via constructor (e.g., `onHabitSelected: (String) -> Unit`) +6. Keep the same State and Event sealed classes +7. Update corresponding Screen composable to accept Component and use `component.state.subscribeAsState()` + +### Phase 5: Platform Entry Points +1. **Android** (`MainActivity.kt`): Use `defaultComponentContext()` extension to create `ComponentContext`, instantiate `RootComponent` +2. **iOS** (`main.ios.kt`): Create lifecycle, create `ComponentContext`, instantiate `RootComponent` +3. **Desktop** (`Main.kt`): Use `LifecycleRegistry` + `defaultComponentContext()` or manual setup + +### Phase 6: DI Migration +1. Expose `DI` instance from `PlatformSDK` (not just `DirectDI`) +2. Pass `DI` to `RootComponent` constructor +3. Each parent component passes `di` to child components +4. Remove `Inject.kt` service locator +5. Components implement `DIAware` and use `by di.instance()` for dependency resolution + +### Phase 7: Cleanup +1. Delete all old ViewModel files +2. Delete `BaseViewModel.kt` +3. Remove `compose-navigation` and `compose-viewmodel` dependencies +4. Delete old navigation files (`AppScreens.kt`, old `MainScreen.kt`) +5. Remove `LocalNavHost` CompositionLocal + +## Acceptance Criteria + +1. All screens render and function identically to the current implementation +2. Navigation between screens works correctly (forward, back) +3. Bottom navigation preserves per-tab navigation state (nested stacks) +4. Splash screen shows and transitions to Main +5. Create habit flow works from root level +6. Detail screens receive correct parameters (habitId, type, etc.) +7. No `androidx.lifecycle.ViewModel` or `NavHost` imports remain in commonMain +8. `compose-navigation` and `compose-viewmodel` dependencies are removed +9. All components use Kodein `DIAware` pattern (no `Inject.instance()` calls) +10. State is exposed via Decompose `Value` +11. Coroutine scopes are properly managed via Essenty lifecycle +12. App compiles and runs on Android, iOS, and Desktop + +## Edge Cases and Risks + +### Risks +- **Large migration surface**: 12+ ViewModels and all navigation in one pass. High risk of regressions. +- **Decompose version compatibility**: Must ensure Decompose version is compatible with the Kotlin 2.0.0 and Compose 1.6.10 versions used. +- **Serialization of navigation configs**: All `Config` classes must be `@Serializable`. If configs contain non-serializable types, custom serializers may be needed. +- **State restoration**: Decompose handles state saving via serializable configs. Current ViewModels don't save state — this is an improvement but needs careful config design. +- **Bottom nav state preservation**: Maintaining multiple `Child Stack` instances for tabs requires careful key management to avoid conflicts. + +### Edge Cases +- **Deep links**: Current app doesn't appear to use deep links, so not a concern. +- **Back button handling**: Decompose's `Child Stack` handles back navigation. Need to ensure proper back behavior on Android (pop within tab before switching tabs). +- **Concurrent navigation**: Ensure rapid tab switching doesn't cause race conditions in stack management. +- **Configuration changes on Android**: Decompose components survive config changes via `StateKeeper` — must ensure this is properly set up. +- **Process death on Android**: `StateKeeper` should persist navigation state. Configs must be serializable. + +## Out of Scope + +- Adding new features or changing existing feature behavior +- Migrating to Material 3 +- Adding unit tests for components (can be done separately) +- Changing the DI module structure (only changing how DI is accessed) +- Refactoring domain/data layers +- Adding deep link support +- Adding animations/transitions between screens (preserve current behavior) +- Migrating `SettingsEventBus` or theming infrastructure +- JS target support (already disabled in current build)
