设置ESLint

设置ESLint

1. 安装组件

   npm i eslint prettier eslint-config-prettier eslint-plugin-prettier  eslint-config-airbnb eslint-plugin-node eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react --save-dev
   

2. 设置规则

   控制off,warn,error
   具体参数设置可以参考官方文档，报错的时候vscode有直接跳转的

   {
     "extends": ["airbnb", "prettier", "plugin:node/recommended"],
     "plugins": ["prettier"],
     "rules": {
       "prettier/prettier": ["error", {}],
       "spaced-comment": "off",
       "no-console": ["warn", { "allow": ["log"], "no-semi": true }],
       "consistent-return": "off",
       "func-names": "off",
       "object-shorthand": "off",
       "no-process-exit": "off",
       "no-param-reassign": "off",
       "no-return-await": "off",
       "no-underscore-dangle": "off",
       "class-methods-use-this": "off",
       "prefer-destructuring": ["error", { "object": true, "array": false }],
       "no-unused-vars": ["error", { "argsIgnorePattern": "req|res|next|val|err" }]
     }
   }
