Simplifying Application Development with Kotlin Multiplatform Mobile

By: Róbert Nagy

Overview of this book

Sharing code between platforms can help developers gain a competitive edge, and Kotlin Multiplatform Mobile (KMM) offers a sensible way to do it. KMM helps mobile teams share code between Android and iOS in a flexible way, leaving room for native development. The book begins by helping you to gain a clear understanding of the Kotlin Multiplatform approach, how it works, and how it is different from cross-platform technologies, such as React Native and Flutter, and code sharing options, such as C++. You'll then see how your team can use this software development kit (SDK) to build native applications more effectively by learning timeless concepts and working through practical examples. As you advance, you'll get to grips with the core concepts, understand why UI sharing fails, and get hands-on with developing a small KMM application. Finally, you'll discover expert tips and best practices, along with production- and adoption-related questions, that will help you take the next step in your project and career. By the end of this Kotlin book, you'll have gained a solid understanding of the capabilities of KMM and be able to share code between Android and iOS flexibly.

The Kotlin/JS compiler

The Kotlin/JS compiler is the final piece of the puzzle for sharing code between different platforms. There are many use cases in which you could leverage this compiler, as follows:

  • Sharing code between the backend and the frontend. If your backend is written in Node.js and you'd like to share code between your backends and frontend, Kotlin/JS can be a great tool.
  • Sharing code between mobile platforms and the web, which is a great way to keep your frontend in sync.

So, what do you need to know about the Kotlin/JS backend compiler?

How it works

Kotlin/JS currently targets the ECMAScript 5 (ES5) JavaScript standard. As we saw with the Kotlin/JVM and Kotlin/Native compilers, Kotlin/JS has a similar process but produces a different type of executable. In short, it takes Kotlin code that it then translates into JavaScript code, given that the underlying code uses dependencies that can run on JavaScript.

It is currently migrating to...
