About This Article
Building WebAssembly applications with Kotlin meant developers had to deal with weak npm dependency management and poor exception handling in JavaScript interop. Production projects needed better tooling to handle these gaps.
JetBrains fixed npm dependency management in Kotlin/Wasm and made exception handling more reliable when working with JavaScript. They also added browser debugging support directly into the development workflow.
Kotlin/Wasm reached Beta status with a new shared source set for js and wasmJs targets. Developers can now write code once and run it across multiple web platforms without duplicating effort.
