Kotlin - One Language, All Tiers: Developing Multiplatform Projects

GOTO Berlin 2017

Kotlin 1.2 introduces experimental support for building multiplatform projects. A multiplatform project allows you to reuse your business logic code, written in Kotlin, between all tiers of an application - the server code running under the JVM, the browser running JavaScript, as well as Android and iOS mobile apps. The shared portion of the code is compiled to all platforms and may delegate to platform-specific implementations of certain APIs or libraries. The platform-specific parts are also written in Kotlin and have full access to the features of each of the supported platforms.

In this talk, we'll look at the language and IDE features that enable multiplatform development in Kotlin, and will study an example project showcasing all the tiers - backend, Web frontend and two mobile apps. We'll also discuss future directions for the evolution of multiplatform development in Kotlin.
