首先要安装eslint和prettier拓展插件

{
    // 是否允许自定义的snippet片段提示
    "editor.snippetSuggestions": "top",
    "editor.fontSize": 14,
    "editor.fontWeight": "400",
    "editor.formatOnType": true,
    "guides.enabled": false,
    "editor.tabSize": 2,
    "git.confirmSync": false,
    "window.zoomLevel": 0,
    "editor.renderWhitespace": "boundary",
    "editor.cursorBlinking": "smooth",
    "editor.minimap.enabled": true,
    "editor.minimap.renderCharacters": false,
    "window.title": "${dirty}${activeEditorMedium}${separator}${rootName}",
    "editor.codeLens": true,
    // 配置文件关联，以便启用对应的提示
    "files.associations": {
      "*.vue": "vue",
      "*.wxss": "css"
    },
    // 配置emmet是否启用tab展开缩写
    "emmet.triggerExpansionOnTab": true,
    // 配置emmet对文件类型的支持
    "emmet.syntaxProfiles": {
      "javascript": "jsx",
      "vue": "html",
      "vue-html": "html"
    },
    // 是否开启eslint检测
    "eslint.enable": true,
    // 文件保存时是否根据eslint进行格式化
    "eslint.autoFixOnSave": true,
    // eslint配置文件
    "eslint.options": {
      "extensions": [".js", ".vue"]
    },
    // eslint能够识别的文件后缀类型
    "eslint.validate": [
      "javascript",
      "javascriptreact",
      {
        "language": "vue",
        "autoFix": true
      },
      {
        "language": "html",
        "autoFix": true
      },
      "vue",
      "html"
    ],
    "search.exclude": {
      "**/node_modules": true,
      "**/bower_components": true,
      "**/dist": true
    },
    "vetur.format.defaultFormatter.html": "prettier",
    // 格式化快捷键（默认）：Shift+Alt+F
    // prettier进行格式化时，开启eslint支持
    "prettier.eslintIntegration": true,
    // 是否使用单引号
    "prettier.singleQuote": true,
    "dart.flutterSdkPath": "/Applications/flutter",
    "[javascript]": {
      "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "git.autofetch": true,
    "search.followSymlinks": false,
    // background相关配置 Start
  }

.eslintrc.js

// https://eslint.org/docs/user-guide/configuring
const switcher = require('./ENV') === 'production' ? 'error' : "off"

module.exports = {
  root: true,
  parser: 'babel-eslint',
  parserOptions: {
    sourceType: 'module'
  },
  env: {
    browser: true,
    node: true,
    es6: true
  },
  // https://github.com/standard/standard/blob/master/docs/RULES-en.md
  "extends": "eslint:recommended",
  // required to lint *.vue files
  plugins: [
    'html'
  ],
  // add your custom rules here
  rules: {
    // allow async-await
    'generator-star-spacing': 'off',
    "indent": ["error", 2],
    "quotes": ["error", "single"],
    "semi": ["error", "never"],
    // allow debugger during development
    "no-console":  switcher,
    'no-debugger': switcher,

    // allow paren-less arrow functions
    'arrow-parens': 0,
    // allow async-await
    'generator-star-spacing': 0,
    // tab or enter key warinring
    'no-tabs': 0,
    'no-mixed-spaces-and-tabs': 1
  }
}

在根目录创建 .prettierrc.js

module.exports = {
    semi: false,//行尾使用分号
    singleQuote: true,//字符串使用单引号
    trailingComma: 'all',//使用尾逗号，对象数组等
    printWidth: 80,//一行80字符数，如果超过会进行换行
    tabWidth: 2,//tab为两个空格
   endOfLine:'auto'
};

基本配置

module.exports = {
  root: true,
  parserOptions: {
    sourceType: 'module'
  },
  parser: "vue-eslint-parser",
  env: {
    browser: true,
    node: true,
    es6: true,
  },
  rules: {
    'no-console': 'off',
  }
}
