An example of Kotlin Multiplatform todo app with shared Android/Desktop Compose UI and SwiftUI (not Compose) iOS.
|
|
|
|
|
|
|
|
|
|
This example supports the following targets:
|
|
|
|
|
- `Android` (Compose)
|
|
|
|
|
- `Desktop/JVM` (Compose)
|
|
|
|
|
- `Web/JavaScript` (Compose)
|
|
|
|
|
- `iOS` (SwiftUI, not Compose)
|
|
|
|
|
|
|
|
|
|
Libraries used:
|
|
|
|
|
- Jetpack Compose - shared UI
|
|
|
|
|
- [Decompose](https://github.com/arkivanov/Decompose) - navigation and lifecycle
|
|
|
|
|
- [MVIKotlin](https://github.com/arkivanov/MVIKotlin) - presentation and business logic
|
|
|
|
|
- [Reaktive](https://github.com/badoo/Reaktive) - background processing and data transformation
|
|
|
|
|
- [SQLDelight](https://github.com/cashapp/sqldelight) - data storage
|
|
|
|
|
|
|
|
|
|
There are multiple modules:
|
|
|
|
|
- `:common:utils` - just some useful helpers
|
|
|
|
|
- `:common:database` - SQLDelight database definition
|
|
|
|
|
- `:common:main` - displays a list of todo items and a text field
|
|
|
|
|
- `:common:edit` - accepts an item id and allows editing
|
|
|
|
|
- `:common:root` - navigates between `main` and `edit` screens
|
|
|
|
|
- `:common:compose-ui` - Shared Compose UI for Android and Desktop
|
|
|
|
|
- `:android` - Android application
|
|
|
|
|
- `:desktop` - Desktop application
|
|
|
|
|
- `:web` - Web browser application + Compose Web UI
|
|
|
|
|
- `ios` - iOS Xcode project
|
|
|
|
|
|
|
|
|
