A lightweight Java and Kotlin web framework

See the jsMain dependency block in the build.gradle.kts file with the full setup. Currently, the application doesn’t save data, meaning that the shopping list vanishes when you terminate the server process. To fix that, use the MongoDB database to store and retrieve shopping list items even when the server shuts down. You’ve laid the groundwork on the client and have a clean API to access the data provided by the server.

Ask the view to show a loading indicator before you start loading the data. Now, update the main() function to print the value of the API_URL property instead of “Hello world! Next, open the Build menu and click on Build Project to compile your Kotlin code to JavaScript. The IDE will generate a new folder called out in your project’s root folder.


In Java, redundancy results in verbose and longer code. Kotlin is simpler, making it easier for beginners to learn. Kotlin focuses on stripped-down, functional code and avoids repetitive boilerplate code. Semicolons at the end of every line are not https://globalcloudteam.com/ needed, although Kotlin does not have an issue if a developer uses them. Additional features reduce the complexity and length of code needed to achieve the end goal of a Kotlin team. Kotlin can be used alongside Java for development on the server.

You’ll need an input component that provides a callback when users submit their entry to the shopping list to receive input. Load the shopping list elements from the server and set the state accordingly. In this configuration, the JsonFeature uses kotlinx.serialization to provide a way to create typesafe HTTP requests. It takes care of automatically converting between Kotlin objects and their JSON representation and vice versa. For a more in-depth view of typical workflows and how apps are developed with React and Kotlin/JS, see the Build a web application with React and Kotlin/JS tutorial. This means that the combined build will work when you run your application, and also when you prepare it for deployment to another target system or cloud platform.

Compared to Java, Kotlin is more understandable and requires fewer lines of code. On average, code in Kotlin is 40% shorter than the same code in Java. Less code and more concise syntax mean fewer bugs would find their way into the final version of the app, while Kotlin’s readability makes it easier to fix issues and maintain the code. Introduced by JetBrains in the 2010s, Kotlin is an open-source general-purpose programming language. It is designed to be fully interoperable with Java, meaning that it compiles into the same bytecode as Java and can execute its code. Kotlin is often used for data science tasks, such as building data pipelines and putting machine learning models into production.

For detailed information on source sets, see Understand Multiplatform project structure. Kotlin source sets are a collection of Kotlin sources and their resources, dependencies, and language settings that belong to one or more targets. You use them to set up platform-specific and common dependency blocks. The serialization plugin provides multiplatform conversions between Kotlin objects and their JSON text representation. You can also join the #javascript channel in the official Kotlin Slack to chat with the community and the team.

Using Kotlin and Ktor, developers can use a custom test engine to run their entire application, and handle requests just like the live application would. You can imagine Kotlin’s popularity by considering that more than 60 percent of top-grossing apps and 71 percent of newly launched apps are based on Kotlin. Most Android developers prefer Kotlin as it resolves a lot of issues with Java coding. Due to its perfect sync with Java, a lot of Android developers use Kotlin to rewrite applications. As well as using for back end web, you can use Kotlin code client-side, for desktop development, and native development.
