Babel 只编译我的 Vue 项目的 js 文件，而不是整个项目

Question

I have a Vue project that that I want to use on old iPad, running iOS/safari version 5. This means I need to transpile it to ES5 using Babel.

This is what my babel.config.js looks like

  presets: [
    //'@vue/cli-plugin-babel/preset',
    ["@babel/env",
    {
      targets: {
        safari: "5",
        ios: "5",
      },
      useBuiltIns: "usage",
      "corejs": "3.6.4",
    },]
  ]
}

Now when I run npx babel src --out-dir dist , babel only compiles the .js files to the dist folder. No .vue files, static assets and html files are compiled/copied to the dist folder.

How can I get Babel to compile not just the .js files, and is there anything else I need to do to transpile my project to ES5?

This is my package.json :

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "@babel/polyfill": "^7.12.1",
    "axios": "^0.20.0",
    "core-js": "^3.6.5",
    "sass": "^1.27.0",
    "sass-loader": "^10.0.3",
    "vue": "^2.6.11",

  },

    "@babel/cli": "^7.12.1",
    "@babel/core": "^7.12.3",
    "@babel/preset-env": "^7.12.1",
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-plugin-router": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^6.2.2",
    "vue-template-compiler": "^2.6.11"
  }
}

这不是 babel 编译静态资产的目的，为此您需要像 webpack 这样的打包器或像 Gulp 这样的任务运行器。
