-------------------------------------------------------------------------------- 1 | # Multiplatform Project Sample for Kotlin 2 | 3 | 4 | **Important** MPP and this project requires Kotlin 1.2-rc39 or higher, and IntelliJ IDEA 2017.3 EAP or higher. 5 | 6 | This project is a sample [multi-platform project for Kotlin](https://kotlinlang.org/docs/reference/multiplatform.html), that is, a project that can target multiple platforms. 7 | 8 | The project consists of 3 modules 9 | 10 | * **Common**: where common code such as data classes and declaration for platform specific code. 11 | * **js**: where Kotlin code targeting JavaScript is located 12 | * **jvm**: where Kotlin code targeting the JVM is located 13 | 14 | For more information on this project, please see the [corresponding blog post](http://hadihariri.com/2017/11/10/multiplatform-projects-with-kotlin). 15 | 16 | 17 | ## License 18 | 19 | The material provided in this repository, including but not limited to source code,
