1、在vscode中先安裝好eslint、prettier插件
2、菜單欄 file->Preferences->settings 搜索eslint 點擊Edit in settings.json 進入到settings.json文件
進行如下配置，頁面保存時會自動格式化
{
"eslint.alwaysShowStatus": true,
"eslint.autoFixOnSave": true,
//配置eslint
"eslint.options": {
"extentions":[
".js",
".vue"
]
},
"eslint.validate": [
"javascript",
{ "language": "vue", "autoFix": true },
"html",
"vue"
],
//為了符合eslint的兩個空格間隔原則
"editor.tabSize": 2,
}
