react项目配置Eslint

npm install --save-dev  eslint-plugin-prettier  eslint-plugin-jsx-a11y eslint-config-airbnb

注意：由于eslint-config-airbnb目前版本已经超过19，会出现一个小问题，箭头函数和命名函数会被Eslint 提示冲突，这是由于19版本的升级导致的解决方案目前有两个  1，在.eslintrc.js 文件中添加了以下规则      'react/function-component-definition': [2, { namedComponents: 'arrow-function', unnamedComponents: 'arrow-function' }],      这样，eslint 将只接受组件的箭头函数，而不是函数表达式（默认情况下）；  2，可以改变函数写法来解决冲突，这样是最简单的      箭头函数：const Demo = () : ReactNode => <div>demo</div>;      function Demo () {         return <div>demo</div>     } 3，通过改变版本去解决冲突，      直接下载指定的版本的包就可以解决，现在自测18.1.0可以满足当下需求；

// .eslintrc.js 如果编辑器module.exports报错，可尝试重启编辑器

module.exports = {   root: true,   extends: ['taro/react', 'airbnb', 'airbnb/hooks'],   parser: '@typescript-eslint/parser', // ESLint 默认使用 esprima 作为其解析器，也可以在配置文件中指定一个不同的解析器（它必须是一个 Node 模块，且它必须符合 parser interface）   plugins: [     'react',     'react-hooks',     'import',     'jsx-a11y'   ],   rules: {     'react/function-component-definition': [2, { namedComponents: 'arrow-function', unnamedComponents: 'arrow-function' }],     'react/jsx-uses-react': 'off',     'react/react-in-jsx-scope': 'off',     'no-undef': 'off',     'import/no-extraneous-dependencies': 'off',     'import/prefer-default-export': 'off',     'import/no-unresolved': 'off',     'no-unused-vars': 'off',     'import/extensions': 'off',     'react/jsx-filename-extension': [1, { extensions: ['.js', '.jsx', '.ts', '.tsx'] }],     indent: ['error', 2, { SwitchCase: 1 }],     'linebreak-style': 'off',     quotes: ['error', 'single'],     semi: ['error', 'always'],     'dot-notation': 'off',     'spaced-comment': 'off',     'comma-dangle': 'off',     'space-before-function-paren': ['error', 'never'],     'one-var': 'off',     'one-var-declaration-per-line': 'off',     'no-use-before-define': 'off',     'no-restricted-globals': ['error', 'history'],     'class-methods-use-this': 'off',     radix: 'off',     'global-require': 'error',     'default-case': 'off',     'no-param-reassign': 'error',     'consistent-return': 'off',     'no-script-url': 'error',     'no-else-return': 'error',     'no-restricted-syntax': 'error',     'no-extend-native': 'error',     'no-return-assign': 'off',     'no-underscore-dangle': 'off',     'no-unused-expressions': ['error', {       allowShortCircuit: true,       allowTernary: true,       allowTaggedTemplates: true     }],     'max-len': ['error', {       code: 200,       ignoreComments: true,       ignoreUrls: true,       ignoreTemplateLiterals: true     }],     'jsx-quotes': ['error', 'prefer-single'],     'jsx-a11y/alt-text': 'off',     'jsx-a11y/no-autofocus': 'off',     'jsx-a11y/label-has-for': 'off',     'jsx-a11y/label-has-associated-control': 'off',     'jsx-a11y/media-has-caption': 'off',     'jsx-a11y/click-events-have-key-events': 'off',     'jsx-a11y/no-noninteractive-element-interactions': 'off',     'jsx-a11y/no-static-element-interactions': 'off',     'jsx-a11y/anchor-is-valid': 'off',     'prefer-destructuring': 'off',     'no-plusplus': 'off',     'no-trailing-spaces': 'off',     'react/prop-types': 'off',     'react/jsx-tag-spacing': 'off',     'import/no-duplicates': 'off',     'import/order': 'off',     'import/no-dynamic-require': 'off',     'react/no-did-update-set-state': 'error',     'react/no-unused-state': 'error',     'react/no-find-dom-node': 'error',     'react/forbid-prop-types': 'off',     'react/jsx-indent-props': 'off',     'react/no-array-index-key': 'off',     'react/require-default-props': 'off',     'react/sort-comp': 'off',     'react/jsx-wrap-multilines': 'off',     'react/destructuring-assignment': 'off',     'react/jsx-closing-bracket-location': 'off',     'react/jsx-first-prop-new-line': 'off',     'react/no-multi-comp': 'off',     'react/jsx-one-expression-per-line': 'off',     'react/no-access-state-in-setstate': 'off',     'react/jsx-no-bind': 'off',     'react/jsx-indent': [2, 2],     'react/no-unescaped-entities': 'off',     'no-prototype-builtins': 'error',     'no-nested-ternary': 'error',     'react-hooks/exhaustive-deps': 'off',     'react/jsx-no-target-blank': 'error',     'no-console': ['off'],     'react/jsx-props-no-spreading': 'off',     'react-hooks/rules-of-hooks': 'error',     'no-useless-constructor': 'off',     'no-empty-function': 'off',     'object-curly-newline': 'off',     'react/no-danger': 'off',     'react/button-has-type': 'off',     'no-multiple-empty-lines': 'off',     'no-useless-escape': 'off',     'react/no-unused-prop-types': 'off',     'react/default-props-match-prop-types': 'off',     camelcase: 'off',   }, };

// 没啥好讲的，直接将不需要检测的路径或文件丢在这里就ok /.git/ /.Vscode/ node_modules// dist/

4.新建.prettierrc.js文件

module.exports = {     tabWidth: 4,     singleQuote: true,     jsxSingleQuote: true,     printWidth: 140,     endOfLine: 'auto', };

.editorconfig 文件用于 统一不同编辑器的代码风格的配置。比如我们要控制一个多人维护的项目缩进统一用4个空格：indent_size = 4

# http://editorconfig.org root = true  [*] indent_style = space indent_size = 4 charset = utf-8 trim_trailing_whitespace = true insert_final_newline = true end_of_line = crlf  [*.md] trim_trailing_whitespace = false

6.修改vscode编辑器的setting.json文件

// jsx自动修复     "editor.formatOnSave": true,     // 保存自动修复     "eslint.autoFixOnSave": true,     "eslint.run": "onSave",     "javascript.format.enable": false,     "editor.codeActionsOnSave": {         "source.fixAll.eslint": true     },     "editor.formatOnPaste": false,     "editor.formatOnType": true,     "files.autoSave": "onFocusChange",     "eslint.nodePath": "",     "files.trimTrailingWhitespace": true,      "eslint.validate": [         "javascript",         "javascriptreact",         {         "language": "html",         "autoFix": true         },         {         "language": "react",         "autoFix": true         }     ]
