-You can also rename the Vue configuration file to `vue.config.mjs` and use static import syntax (you should use latest `@vue/cli-service ^5.0.8`):
-```ts
-// vue.config.mjs
-import AutoImport from 'unplugin-auto-import/webpack'
-
-export default {
-  configureWebpack: {
-    plugins: [
-      AutoImport({ /* options */ }),
