关闭ESlint

在vue.config.js文件中配置

module.exports = {

 lintOnSave: false,  //设为flase禁用eslint

}

Eslint具体规则 eslintrc.js 文件配置

module.exports = {
 root: true,
 parser: 'babel-eslint',
 parserOptions: {
   sourceType: 'module',

使用ESlint快速格式化符合规范代码

首先在VScode中安装Prettier 插件
然后在根目录创建.prettierrc.js文件

文件内配置
module.exports = {
    //尾逗号禁用
    trailingComma: 'none', //禁用尾部分号
    semi: false, //是否用单引号
    singleQuote: true
}
