Perfect timing! I just had a question on this and your article solved the problem I had! I tried and it works beautifully!

Just a couple of minor improvements:

• The build script can be made a simple executable by adding !/usr/bin/env node as the first line and then running chmod +x build.js
• After this the scripts section in package.json can be updated to run this script when npm run build is called:

  "scripts": {
    "start": "vite",
    "dev": "vite",
    "build": "./build.js",
    "serve": "vite preview"
  },
  

For typescript, I found that I simply needed to change the entryPoints value to entryPoints: ["src/index.tsx"],.
