WebAssembly Support in JavaFX WebKit

Mon Nov 13 17:27:01 UTC 2023

First, big thanks to the folks who have maintained this project.

I recently opened a "Feature Request" ticket for "WebAssembly Support in
JavaFX WebKit", and stated that I would be happy to help get this support
enabled. WebAssembly has been enabled in WebKit since 2017:
https://webkit.org/blog/7691/webassembly/

The basic gist is: when I run load the following HTML, I get "undefined"
rather than "object":

<-- index.html -->
<!DOCTYPE html>
<html>
  <body>
    Hello from Webkit!
    <div id="console"></div>
    <script type="text/javascript">
      var app = document.getElementById("console");
      app.innerHTML = typeof WebAssembly; // Should return "object"
  </body>
</html>

I can see that all of the relevant .h/.cpp files from the WebKit project
are indeed included:
https://github.com/openjdk/jfx/tree/master/modules/javafx.web/src/main/native/Source/JavaScriptCore/wasm

I am not sure why this would fail. Might it be that WebAssembly simply
needs to be enabled in the JavaFX build script?

Thank you in advance!
