在package.json中 添加 ESLint依赖，

"eslint": "3.9.0","eslint-config-airbnb": "12.0.0","eslint-plugin-import": "2.0.1","eslint-plugin-jsx-a11y": "2.2.3","eslint-plugin-react": "6.4.1","eslint-plugin-redux-saga": "0.1.5",

并配置

1 ESLint运行

eslint --color app/**/*.js

添加 –fix 可以自动修复一些简单错误，一些规则 如：
no-extra-parens 禁止冗余的括号
no-extra-semi 禁止多余的分号

2 常见错误

jsx-no-bind

含义： 将自定义函数在构造函数中绑定， 如果JSX prop 中存在bind，则每次render 生成一个新的function，这样会影响性能。
解决办法， 在构造函数中 绑定 this

class Foo extends React.Component {
  constructor() {
    super();
    this._onClick = this._onClick.bind(this);
  }
  render() {
    return (
      <div onClick={this._onClick}>
        Hello!
      </div>
    );
  }
  _onClick() {
    // Do whatever you like,referencing "this" as appropriate
  }
}

sort-comp

含义：React中函数的先后顺序
默认的排序，其中everything-else是自定义函数

{ order: [ 'static-methods','lifecycle','everything-else','render' ],groups: { lifecycle: [ 'displayName','propTypes','contextTypes','childContextTypes','mixins','statics','defaultProps','constructor','getDefaultProps','getInitialState','state','getChildContext','componentWillMount','componentDidMount','componentWillReceiveProps','shouldComponentUpdate','componentWillUpdate','componentDidUpdate','componentWillUnmount' ] }
}
static-methods is a spe

通过注释的方式 解决

/* eslint-disable */ 某文件 ESLint不检测

/* global variable:false */ 设置全局变量
