React specific linting rules for ESLint
用于React的ESLint规则
Installation 安装 Install ESLint either locally or globally.
可以全局或本地安装

$ npm install eslint --save-dev

If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally.
如果您全局安装ESLint,您不得不也全局安装React组件，否则就本地安装它。

$ npm install eslint-plugin-react --save-dev

Configuration 配置 Use our preset to get reasonable defaults:
使用我们的预先设置来获得合理的默认值：

"extends": [ "eslint:recommended", "plugin:react/recommended" ]

You should also specify settings that will be shared across all the plugin rules.
您还应该指定将在所有插件规则之间共享的设置。

{ "settings": { "react": { "createClass": "createReactClass", // Regex for Component Factory to use, //使用组件工厂规则 // default to "createReactClass" "pragma": "React",// Pragma to use, default to "React" 默认使用React语法 "version": "detect", // React version. "detect" automatically picks the version you have installed. React版本，自动检索你安装的版本 // You can also use `16.0`, `16.3`, etc, if you want to override the detected value. 如果你想重写检索值，你也可以使用16.0，16.3等值。 "flowVersion": "0.53" // Flow version//流程版本 }, "propWrapperFunctions": [ // The names of any function used to wrap propTypes, e.g. `forbidExtraProps`. If this isn't set, any propTypes wrapped in a function will be skipped. 任何函数名常常用于包裹propTypes，例如"forbidExtraProps"，如果没有被设置，任何被函数包裹的propType将被忽略。 "forbidExtraProps", {"property": "freeze", "object": "Object"}, {"property": "myFavoriteWrapper"} ] } }

If you do not use a preset you will need to specify individual rules and add extra configuration.
如果你没有使用预先设置,你就需要指定独有规则，并且添加额外的配置。
Add "react" to the plugins section.
添加"react"到插件部分

{ "plugins": [ "react" ] }
