Question

我试图将React CSS模块添加到我的项目中，但我遇到了eslint的问题。我的登录视图如下所示：

＆＃13;

import React, { PropTypes as T } from 'react';
import {ButtonToolbar, Button} from 'react-bootstrap';
import Messages from '../Messages/Messages';
import AuthService from '../../utils/AuthService';
import CSSModules from 'react-css-modules';
import styles from './styles.module.css';

class Login extends React.Component {

    render() {

        let rootStyle = {
            textAlign: 'center'
        };

        let toolbarStyle = {
            display: 'inline-block'
        };

        const { auth } = this.props;

        return (
            <div styleName="root">
                <h2>Login</h2>
                <Messages auth={this.props.auth}></Messages>
                <ButtonToolbar styleName="toolbar">
                    <Button bsStyle="primary" onClick={auth.login.bind(this)}>Login</Button>
                </ButtonToolbar>
            </div>
        );
    }
}

Login.PropTypes = {
    location: T.object,
    auth: T.instanceOf(AuthService)
};

export default CSSModules(Login, styles);

这是我原来的.eslintrc文件，在添加导入/忽略设置之前：

{
   "extends": [
      "eslint:recommended",
      "plugin:import/errors",
      "plugin:import/warnings"
   ],

      "react"
   ],
   "parserOptions": {

      }
   },

      "react/self-closing-comp": 1,
      "react/sort-comp": 1,
      "react/wrap-multilines": 1
   }
}

通过eslint运行此操作会给我带来2个错误：

6:20  error    Parse errors in imported module './styles.module.css': Unexpected token . (1:1)  import/namespace
6:20  error    Parse errors in imported module './styles.module.css': Unexpected token . (1:1)  import/default

当我将以下设置添加到.eslintrc文件时：

   "settings": {
      "import/ignore": [".css$"]
   }

解析错误消失了，但是以下错误取而代之：

1:8   error    No default export found in module      import/default
1:17  error    PropTypes not found in 'react'         import/named
5:8   error    No default export found in module      import/default

关于如何让eslint与React CSS Modules搭配好玩的任何建议？

Answer 1

我确实找到了一个解决方案：如果我将.eslintrc中的导入/忽略设置更改为

    "settings": {
      "import/ignore": [".css$","node_modules/*"]
   }

然后所有的掉毛错误都消失了。我想可以避免在node_modules中扯掉所有东西，但是它唠叨我，我不知道造成错误的原因是什么。

Answer 2

这是因为 import styles from './styles.module.css'; 使 Node 尝试像加载 JS 一样加载 CSS 模块，并且在您的情况下它会导致服务器端渲染或 Jest 崩溃。正确的解决方案是为服务器端/Jest 执行配置 Babel，将这些 CSS 导入转换为样式映射，就像 Webpack 所做的那样。有a plugin for that。

使用react css模块进行eslint
