PeopleInSpace

Minimal Kotlin Multiplatform project using Jetpack Compose and SwiftUI. Currently running on

• Android
• iOS
• watchOS
• macOS
• Web
• JVM (small Ktor back end service)

It makes use of basic API (http://open-notify.org/Open-Notify-API/People-In-Space/) to show list of people currently in space (inspired by https://kousenit.org/2019/12/19/a-few-astronomical-examples-in-kotlin/)! The list is shown on Android using Jetpack Compose, on iOS using SwiftUI and on Web using Kotlin/JS React wrapper.

Note that this repository very much errs on the side of mimimalism to help more clearly illustrate key moving parts of a Koltin Multiplatform project and also to hopefully help someone just starting to explore KMP to get up and running for first time (and is of course primarily focussed on use of Jetpack Compose and SwiftUI). If you're at stage of moving beyond this then I'd definitely recommend checking out KaMPKit

Building

You need to use Android Studio v4.2 (currently preview/canary version). Have tested on XCode v11 and v12. When opening iOS/watchOS/macOS projects remember to open .xcworkspace file (and not .xcodeproj one). To exercise web client run ./gradlew :web:browserDevelopmentRun.

Languages, libraries and tools used

• Kotlin
• Kotlin Coroutines
• Kotlinx Serialization
• Ktor client library
• Android Architecture Components
• Koin
• Jetpack Compose
• SwiftUI
