It makes use of [Open Notify PeopleInSpace API ](http://open-notify.org/Open-Notify-API/People-In-Space/ ) to show list of people currently in

space and also the position of the International Space Station (inspired by https://kousenit.org/2019/12/19/a-few-astronomical-examples-in-kotlin/)!

The project is included as sample in the official [Kotlin Multiplatform Mobile docs ](https://kotlinlang.org/docs/mobile/samples.html#peopleinspace ) and also the [Google Dev Library ](https://devlibrary.withgoogle.com/products/android )

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
2021-04-25 17:47:32 +00:00
beyond this then I'd definitely recommend checking out [KaMPKit ](https://github.com/touchlab/KaMPKit ) from Touchlab.
I also have the following samples that demonstrate the use of a variety of Kotlin Multiplatform libraries (and also use Jetpack Compose and SwiftUI).

### Building
2021-05-31 13:02:28 +00:00
You need to use Android Studio Arctic Fox (**note: Java 11 is now the minimum version required**). Have tested with XCode v11 and v12.
When opening iOS/watchOS/macOS projects remember to open `.xcworkspace` file (and not `.xcodeproj` one).
To exercise (React based) web client run `./gradlew :web:browserDevelopmentRun` .
2021-04-25 09:18:06 +00:00
To run backend you can either run `./gradlew :backend:run` or run `Server.kt` directly from Android Studio.
2021-05-31 13:02:28 +00:00
2021-04-25 09:18:06 +00:00
After doing that you should then for example be able to open `http://localhost:9090/astros_local.json` in a browser.

2021-05-11 18:48:28 +00:00
### Compose for Web client
The Compose for Web client resides in the `compose-web` module and can be run by
2021-05-20 19:05:57 +00:00
invoking `./gradlew :compose-web:jsBrowserDevelopmentRun`
2021-05-11 18:48:28 +00:00
### Compose for Desktop client
2020-11-17 16:58:10 +00:00
2021-02-13 15:03:17 +00:00
This client is available in `compose-desktop` module. Note that you need to use appropriate version of JVM when running (works for example with Java 11)

### Deploying backend code
Have tested this out in Google App Engine deployment. Using shadowJar plugin to create an "uber" jar and then deploying it as shown below. Should be possible to deploy this jar to other services as well.
```
./gradlew :backend:shadowJar
gcloud app deploy backend/build/libs/backend-all.jar
```
