const Components = require("unplugin-vue-components/webpack");
const { ElementPlusResolver } = require("unplugin-vue-components/resolvers");
module.exports = defineConfig({
  transpileDependencies: true,
  configureWebpack: {
    plugins: [
      AutoImport({
        resolvers: [ElementPlusResolver()],
      }),
      Components({
