1、在vscode中先安装好eslint、prettier插件
2、菜单栏 file->Preferences->settings 搜索eslint 点击Edit in settings.json 进入到settings.json文件
进行如下配置，页面保存时会自动格式化
{
"eslint.alwaysShowStatus": true,
"eslint.autoFixOnSave": true,
//配置eslint
"eslint.options": {
"extentions":[
".js",
".vue"
]
},
"eslint.validate": [
"javascript",
{ "language": "vue", "autoFix": true },
"html",
"vue"
],
//为了符合eslint的两个空格间隔原则
"editor.tabSize": 2,
}
