最近新建一个vue-cli4的项目，初始化的时候没开启eslint，后面想开启的时候不好配置，这里就做个开启eslint和保存时自动修复格式的总结
vscode首先安装eslint插件
配置vscode的自动保存eslint格式
Ctrl+shift+p
把下面代码复制到里面
"editor.tabSize": 2,
"eslint.alwaysShowStatus": true,
"eslint.autoFixOnSave": true,
"eslint.packageManager": "yarn",
"eslint.validate": [
"javascript", // 用eslint的规则检测js文件
{
"language": "js",
"autoFix": true
},
{
"language": "vue",
"autoFix": true
},
],
"eslint.options": {
"extensions": [
".js",
".vue"
]
},
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
"eslint.run": "onSave",
"files.autoSaveDelay": 3000,
"eslint.codeAction.disableRuleComment": {
},
"files.autoSave": "off",
项目中安装eslint
在package.json文件中的devDependencies里面添加
"@vue/cli-plugin-eslint": "~4.4.0", "babel-eslint": "^10.1.0", "eslint": "^6.7.2", "eslint-plugin-vue": "^6.2.2",
vue.config.js文件里面lintOnSave改成"warning"
根目录添加eslint配置文件
.eslintrc.js
内容根据需要修改

"node": true
},
