• I'm only interested in using the output of wasm-pack after it has been deployed to npm (or used locally as an npm dep).
• I ended up using vite-plugin-wasm-pack, I also tried vite-plugin-wasm but ran into issues.
• Make sure you build your wasm-pack project with wasm-pack build --target web
• Make sure that all the names used to build and deploy your project are the same (at first I was building x-wasm and then naming the npm dep x switching to x-wasm worked).
• In the package.json for the generated wasm-pack output you'll need to add "type": "module" and "main": x_wasm.js.
  • 📝 TODO I need to look into how to do this automatically.
• In vite.config.js add the following plugin wasmPack([], ['x-wasm'])
• Below are two examples of using wasm code from js

Regular js

public class Test {
  public static void main(String []args){
    final var x = 5;
    // You can do something like this in Kotlin/Scala etc but not Java
    // final var t = if (x == 0) {
    //     "zero";
    // } else if (x > 0) {
    //     "pos";
    // } else {
    //     "neg";
