@simonswiss here is my package.json looks like:

{
  "name": "react-from-scratch",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "vite",
    "jsx": "babel input.jsx --presets=@babel/preset-react --out-file output.js --watch"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@babel/cli": "^7.28.0",
    "@babel/core": "^7.28.0",
    "@babel/preset-react": "^7.27.1",
    "vite": "^7.0.6"
  }
}
