VSCODE 配置eslint规则和自动修复

VSCODE 配置eslint规则和自动修复

• vscode安装以下插件

  EsLint、vetur、Prettier - Code formatter

• vscode设置了添加配置项，，默认会去查找你项目中的eslint配置文件

    
    "workbench.iconTheme": "material-icon-theme",
    "explorer.confirmDragAndDrop": false,
    "explorer.confirmDelete": false,
    //配置eslint
    "eslint.autoFixOnSave": true,  //  启用保存时自动修复,默认只支持.js文件
    "eslint.validate": [
       "javascript",  //  用eslint的规则检测js文件
       
         "language": "vue",   // 检测vue文件
         "autoFix": true   //  为vue文件开启保存自动修复的功能
       ,
       
         "language": "html",
         "autoFix": true
       ,
     ],
  
  
  

• 项目中创建.eslitrc.js配置 文件,可能比较多

      module.exports =

    parserOptions: 
      parser: 'babel-eslint',
      sourceType: 'module'
    ,

      node: true,
      es6: true,
    ,
    extends: ['plugin:vue/recommended', 'eslint:recommended'],
  
    // add your custom rules here
    //it is base on https://github.com/vuejs/eslint-config-vue
