This example shows how to create a simple Android/iOS/JVM/JS project sharing some Kotlin code. This app saves on a local database your favourites locations and get the current weather of them from OpenWeatherMap.

In this app we share common code for both platforms (Android/iOS) to get data from an API (in this case OpenWeatherMap). The libraries that we use are:

- [KTOR](https://github.com/ktorio/ktor): to make HTTP requests

- [Serialization](https://github.com/Kotlin/kotlinx.serialization): to De/Serializing JSON 

- [SqlDelight](https://github.com/square/sqldelight): Local database shared between Android & iOS 

Tests:

- [MockK](https://mockk.io/#gradlemaven-dependency): mocking library for Kotlin



### Android App - Master Branch

With this app you can get the weather of your locations using KTor:



And add and save on SQLDelight database your favourite locations:



### iOS App

Open XCode and select the project:



### JVM - Desktop App

To execute this version as desktop app, you have to execute this code on your console:

```

./gradlew JavaFxApp:run

```

By default the JDBC SQLite is created in memory. If you want to persist your database in your disk, you have to indicate the path when you create the database driver:

```

SQLDriver.kt

JdbcSqliteDriver("jdbc:sqlite:$your_database_path")

```



### JS App 

If you want to launch a web to get the weather you can try executing the next commands:

```

./gradlew JsApp:run

./gradlew BackEnd:run

--> localhost:8080

```

Current weather is not shown when you launch the browser? If you have this problem (Module not found: Error: Can't resolve 'core-js/features/object/assign') try to reinstall the node module core-js:

```

npm install core-js

```
