vscode 前端编译工具安装eslint

1. 首先现在vscode插件中找到eslint插件安装并重启(才能生效)

2. 在vscode中找到设置——扩展(eslint)——(setting)配置一下代码

{
  "files.associations": {
    "*.cjson": "jsonc",
    "*.wxss": "css",
    "*.wxs": "javascript"
  },
  "emmet.includeLanguages": {
    "wxml": "html"
  },
  "minapp-vscode.disableAutoConfig": true,
  "eslint.codeAction.showDocumentation": {
    "enable": true
  },
  // vscode默认启用了根据文件类型自动设置tabsize的选项
  "editor.detectIndentation": false,
  // 重新设定tabsize
  "editor.tabSize": 2,
  // #每次保存的时候自动格式化
  "editor.formatOnSave": true,
  // #每次保存的时候将代码按eslint格式进行修复
  "eslint.autoFixOnSave": true,
  // 添加 vue 支持
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    {
      "language": "vue",
      "autoFix": true
    }
  ],
  //  #让prettier使用eslint的代码格式进行校验
  "prettier.eslintIntegration": true,
  //  #去掉代码结尾的分号
  "prettier.semi": false,
  //  #使用带引号替代双引号
  "prettier.singleQuote": true,
  //  #让函数(名)和后面的括号之间加个空格
  "javascript.format.insertSpaceBeforeFunctionParenthesis": true,
  // #让vue中的js按编辑器自带的ts格式进行格式化
  "vetur.format.defaultFormatter.js": "vscode-typescript",
  "vetur.format.defaultFormatterOptions": {
    "js-beautify-html": {
      "wrap_attributes": "force-aligned"
      // #vue组件中html代码格式化样式
    }
  },
  "window.zoomLevel": 0,
  "explorer.confirmDelete": false,
  "explorer.confirmDragAndDrop": false,
  "editor.renderControlCharacters": true,
  "editor.renderWhitespace": "all",
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
  }
}

 3. 在文件中创建一个 .eslintrc.js 的文件 代码如下:

module.exports = {
  root: true,
  parserOptions: {
    parser: 'babel-eslint'
  },
  env: {
    browser: true
  },
  extends: [
    // https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
    // consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
    'plugin:vue/essential',
    // https://github.com/standard/standard/blob/master/docs/RULES-en.md
    'standard'
  ],
  // required to lint *.vue files
  plugins: ['vue'],
  // add your custom rules here
  rules: {
    // allow async-await
    'no-console': 'off',
    indent: ['error', 2, { SwitchCase: 1 }],
    semi: ['error', 'always'],
    'space-before-function-paren': [
      'error',
      { anonymous: 'always', named: 'never' }
    ],
    'generator-star-spacing': 'off',
    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off'
  }
}

完成以上步骤即可。
