parcel 按需引入element

​​.babelrc​​

{
  "presets": [["@babel/preset-env", { "modules": false }]],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}

​​package.json​​构建后打的包就是几十k

"scripts": {
    "dev": "parcel public/index.html --out-dir dist",
    "serve": "npm run dev",
    "build": "rm -rf build && parcel build public/index.html --no-cache --out-dir build --public-url ."
  },
