如何将带有装饰器的 React 组件重写为纯函数?
How do I rewrite a react component with decorators as a pure function?
我正在使用 airbnb eslint 设置,其中包含 a rule that enforces stateless react components to be rewritten as a pure function。下面的组件触发这个规则,这意味着下面的组件最好写成一个纯函数:
import React from 'react';
import { observer } from 'mobx-react';
import cssmodules from 'react-css-modules';
import styles from './index.css';
import Select from '../Select/';
import List from '../List/';
@cssmodules(styles)
@observer
export default class Analysis extends React.Component {
render() {
return (
<div styleName="wrapper">
<div styleName="column">
<Select store={this.props.store} />
</div>
<div styleName="column">
<List store={this.props.store} />
</div>
</div>
);
}
}
Analysis.propTypes = {
store: React.PropTypes.object.isRequired,
};
然而,当我将它重写为一个纯函数时(见下文),我得到了 Leading decorators must be attached to a class declaration
:
的错误
import React from 'react';
import { observer } from 'mobx-react';
import cssmodules from 'react-css-modules';
import styles from './index.css';
import Select from '../Select/';
import List from '../List/';
@cssmodules(styles)
@observer
function Analysis(props) {
return (
<div styleName="wrapper">
<div styleName="column">
<Select store={props.store} />
</div>
<div styleName="column">
<List store={props.store} />
</div>
</div>
);
}
Analysis.propTypes = {
store: React.PropTypes.object.isRequired,
};
那么我可以把它写成一个纯组件并仍然附加装饰器吗?或者这是 airbnb linting 规则的错误,是不是不可能同时满足这两个规则?
好的,所以问题出在 es7 风格的装饰器上。将它们脱糖解决了问题:
import React from 'react';
import { observer } from 'mobx-react';
import cssmodules from 'react-css-modules';
import styles from './index.css';
import Select from '../Select/';
import List from '../List/';
function Analysis(props) {
return (
<div styleName="wrapper">
<div styleName="column">
<Select store={props.store} />
</div>
<div styleName="column">
<List store={props.store} />
</div>
</div>
);
}
Analysis.propTypes = {
store: React.PropTypes.object.isRequired,
};
export default cssmodules(observer(Analysis), styles);
它不是很漂亮,但它确实有效并且不会触发任何错误。
