Jetsnack

Web version of Jetsnack application built with Compose Multiplatform for Web and Kotlin/Wasm.

Kotlin/Wasm

Kotlin/Wasm is a new experimental target that enables developers to compile Kotlin code to WebAssembly (Wasm).

By compiling Kotlin code to WebAssembly, you can run it on any WebAssembly-compatible environment that meets Kotlin's requirements, including web browsers. This creates numerous opportunities, such as developing high-performance web applications and serverless functions.

Compose Multiplatform for Web

Compose for Web is based on Kotlin/Wasm, the newest target for Kotlin Multiplatform projects. It allows you to run your code in the browser with all the benefits that WebAssembly has to offer, such as good and predictable performance for your applications.

Setup environment

IDE

We recommend using IntelliJ IDEA 2023.1 or later to work with the project. It has Kotlin/Wasm support out of the box.

Browser (for Kotlin/Wasm target)

To run applications built with Kotlin/Wasm in a browser, you need a browser supporting wasm garbage collection feature:

• For Chrome and Chromium-based browsers (Edge, Brave etc.), it should just work since version 119.
• For Firefox 120 it should just work.
• For Firefox 119:
  1. Open about:config in the browser.
  2. Enable javascript.options.wasm_gc.
  3. Refresh the page.
