todoapp

An example of Kotlin Multiplatform todo app with shared Jetpack Compose UI.

Supported targets: Android and JVM.

Libraries used:

• Jetpack Compose - shared UI
• Decompose - navigation and lifecycle
• MVIKotlin - presentation and business logic
• Reaktive - background processing and data transformation
• SQLDelight - data storage

There are multiple common modules:

• utils - just some useful helpers
• database - SQLDelight database definition
• main - displays a list of todo items and a text field
• edit - accepts an item id and allows editing
• root - navigates between main and edit screens

The root module is integrated into both Android and Desktop apps.

Features:

• 99% of the code is shared: data, business logic, presentation, navigation and UI
• View state is preserved when navigating between screens, Android configuration change, etc.
• Model-View-Intent (aka MVI) architectural pattern
