You can also share business logic between your web interface and mobile apps for Android and iOS, and avoid duplicating commonly used functionality, like providing abstractions around REST API endpoints, user authentication, or your domain models.Ĭreate libraries for use with JavaScript and TypeScript If your backend is written in Kotlin, you can share common code such as data models or validation logic with a frontend written in Kotlin/JS, which allows you to write and maintain full-stack web applications. Use Kotlin's multiplatform projects to share code with other Kotlin targetsĪll the functionality of Kotlin/JS can also be accessed when using the Kotlin multiplatform Gradle plugin. With kotlinx-nodejs, you have typesafe access to the Node.js API directly from your Kotlin code. This gives you all the advantages of executing in a JavaScript runtime, such as faster startup and a reduced memory footprint. The Node.js target provided by Kotlin/JS enables you to create applications that run on a server or are executed on serverless infrastructure. Write server-side and serverless applications using Kotlin/JS Use the Kotlin/JS frameworks, which take full advantage of Kotlin concepts and its expressive power and conciseness. Interoperability with the JavaScript ecosystem means that you can also use third-party React components and component libraries. kotlin-wrappers also provides support for a select number of adjacent technologies, like react-redux, react-router, and styled-components. Write full, type-safe React applications with Kotlin/JS using the kotlin-wrappers provided by JetBrains, which provide convenient abstractions and deep integrations for React and other popular JavaScript frameworks. Create, modify, and interact with the elements in the Document Object Model (DOM), use Kotlin code to control the rendering of canvas or WebGL components, and enjoy access to many more features that modern browsers support. Kotlin/JS allows you to leverage powerful browser and web APIs in a type-safe fashion. Write frontend web applications using Kotlin/JS Here is a non-exhaustive list of scenarios in which you can use Kotlin/JS: There are numerous ways to use Kotlin/JS. To get an overview of the available options, check out the Kotlin/JS project setup documentation. This includes essential functionality such as controlling the bundling of your application, adding JavaScript dependencies directly from npm, and more. They let you easily set up and control Kotlin projects targeting JavaScript in one place. The recommended way to use Kotlin/JS is via the kotlin.js and kotlin.multiplatform Gradle plugins. The current implementation of Kotlin/JS targets ES5. Kotlin/JS provides the ability to transpile your Kotlin code, the Kotlin standard library, and any compatible dependencies to JavaScript.
