Lazy Loading of Stimulus Controller & Solve "could not resolve"

[CPloscaru]

Hello,

I am to move from importmap to jsbuilding-rails with bun.
I have actually two issue.

1. I can't figure out how to registrer my stimulus controller, since

import { eagerLoadControllersFrom } from "@hotwired/stimulus-loading"
eagerLoadControllersFrom("controllers", application)

do not work

2. I have install react and react domg but can't I have issue bun could not resolve "React" or "ReactDom" inside stimulus controller.

I have tried with "bun-stimulus-plugin" but can"t make it worker either :(

My bun.config.js:

import path from 'path';
import fs from 'fs';
import { bunStimulusPlugin } from 'bun-stimulus-plugin';

const config = {
  sourcemap: "external",
  entrypoints: ["app/javascript/application.js"],
  outdir: path.join(process.cwd(), "app/assets/builds"),
  throw: !process.argv.includes('--watch'),
  plugins: [
    bunStimulusPlugin({
      namespace: "stimulus",  
      controllersPath: "./app/javascript/controllers",
    }),
  ],
};

const build = async (config) => {
  const result = await Bun.build(config);

  if (!result.success) {
    console.error("Build failed");
    for (const message of result.logs) {
      console.error(message);
    }
  }
};

(async () => {
  await build(config);

  if (process.argv.includes('--watch')) {
    fs.watch(path.join(process.cwd(), "app/javascript"), { recursive: true }, (eventType, filename) => {
      console.log(`File changed: ${filename}. Rebuilding...`);
      build(config);
    });
  } else {
    process.exit(0);
  }
})();

my package.json:

{
  "name": "app",
  "private": true,
  "scripts": {
    "build": "bun bun.config.js",
    "build:css": "tailwindcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css --minify"
  },
