JavaFX on Android

The Kotlin multiplatform wasmJs target runs in the browser as an ordinary web app. You can serve the static files the build produces and you’re done: open a URL, the app loads. No service worker, no manifest, nothing special. You can, however, go one step further and package that same output as a Progressive Web App (PWA). This article shows how to get that right.

Shipping a Kotlin Compose Multiplatform app as a PWA: getting updates and caching right

Kotlin Compose Multiplatform runs one UI codebase on desktop (JVM), Android, iOS and the web (wasmJs). The first three targets are all processes on an operating system, and they differ from each other in degree. The web differs in kind. Code written for the other targets rests on assumptions that were never written down because they had always been true: that threads exist, that there is a filesystem, and that the process controls its own lifetime.

This article sets out what those assumptions are and where the web breaks them. It concerns the canvas-rendered wasmJs target, which runs the same Compose UI code as the desktop and mobile builds. It does not cover Compose HTML, the DOM-based library for conventional web pages.

What the browser takes away: the platform limits of Compose Multiplatform on wasmJs
