vue3 + vite 项目搭建 - 配置eslint

安装依赖

 "devDependencies": {
	"standard": "^16.0.3",
    "vue-eslint-parser": "^7.10.0",
    "@typescript-eslint/parser": "^4.29.0",
    "@typescript-eslint/eslint-plugin": "^4.29.0",
    "eslint-plugin-vue": "^7.15.1",
    "eslint": "^7.32.0",

   }

如果想使用最新版本的，可以新增一个命令

"scripts": {
    "update": "ncu -u && cnpm i"
  },

配置规则 在根目录创建 .eslintrc.js

  root: true,
