Note Web support is Experimental and may be changed at any time. Use it only for evaluation purposes. We would appreciate your feedback on it in the public Slack channel #compose-web. If you face any issues, please report them on GitHub.
You can experiment with sharing your mobile or desktop UIs with the web. Compose for Web is based on Kotlin/Wasm, the newest target for Kotlin Multiplatform projects. It allows Kotlin developers to run their code in the browser with all the benefits that WebAssembly has to offer, such as good and predictable performance for your applications.
This project is an experiment with Compose for Web.
The site made with it represents elements about me as a programmer.
A deployed version of it can be found here.
Check out the repo, navigate to the project folder, and use the following commands:
./gradlew :webApp:wasmJsRun
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:
- Open
about:configin the browser. - Enable javascript.options.wasm_gc.
- Refresh the page.
- Open
For more information see https://kotl.in/wasm_help/.
We recommend using IntelliJ IDEA 2023.1 or newer to work with the project.
The experience is quite limited on mobile because scrollable elements don't work on mobile devices yet. See the related issue on compose multiplatform repository.
