// 获取 VUE_APP_ENV 非 NODE_ENV，测试环境依然 console
const IS_PROD = ["production", "prod"].includes(process.env.VUE_APP_ENV);
const plugins = [
  [
    "import",
    {
      libraryName: "vant",
      libraryDirectory: "es",
      style: true,
    },
    "vant",
  ],
];
// 去除 console.log
if (IS_PROD) {
  plugins.push("transform-remove-console");
}

module.exports = {
  presets: [["@vue/cli-plugin-babel/preset", { useBuiltIns: "entry" }]],
  plugins,
