如何处理反应服务器端渲染的css导入

Question

这与在Isomorphic React Components中导入CSS文件非常相似

但建议的解决方案提出了一个条件语句,用于检查导入是从服务器还是浏览器完成的.问题是我在组件本身使用导入对象,如下所示

<a href="/auth/github" className={style.link}>Sign up with github </a>

但是style未定义,因为我不在服务器上导入它.建议的另一种方法webpack-isomorphic-tools也要求我捆绑服务器端代码.这种方法也迫使你在服务器端使用webpack,我并不热衷于此.

基本上这是我的组件

import React from 'react';
import SignUp from './SignUp'
import {Link} from 'react-router'
import {connect} from 'react-redux';
import Modal from 'react-modal'
import style from './app.css'

class App extends React.Component{

  componentDidMount(){
    console.log('mounted')
  }

  render(){
    return (
      <div>
        <p> Hello Kj</p>
          <a href="/auth/github" className={style.link}>Sign up with github </a>
          <a href="/logout" className={style.logout}> Logout </a>
          <Link to ='/project'>Project</Link>
          <button onClick={this.openModal}> Login </button>
        <h1> {this.props.username} </h1>
        <h2> {this.props.email} </h2>
        <div> {this.props.children} </div>
      </div>
    )
  }
}

从服务器端渲染会引发错误

无论如何我可以在不使用webpack的情况下处理这个问题吗？

Answer 1

我实际上找到了一种使用https://github.com/michalkvasnicak/babel-plugin-css-modules-transform的方法

在我使用的 package.json 文件中

"start": "nodemon server/server.js --exec babel-node --plugins css-modules-transform"

目前有效
