Question

尝试用我的新项目实现同构渲染，所以我读了许多文章，如css-loader，状态共享等等。因此，经过一番努力，我在服务器端使用css locals渲染我的页面。所以我继续开始构建其他页面因为一切看起来很棒，直到我没有在我的浏览器上禁用javascript 。那我发现从服务器收到的html的差异有不同的css本地className，bundle.css有不同。我真的卡住了。

这是我的webpack.config。我知道我做错了什么。如果你指出，我很感激。

const webpack = require('webpack');
const path = require('path');
const context = path.resolve(__dirname, 'src');
const nodeExternals = require('webpack-node-externals');

const config = {
    name:"client",
    context,

            },
            {
                test: /\.(eot|woff|woff2|ttf|svg)(\?[\s\S]+)?$/,
                loader: 'url-loader?limit=1000&name=./fonts/[name].[ext]?[hash:base64:5]#icomoon',

    },
    resolve: {
        extensions: ['.jsx', '.js', '.json']
    }
};

module.exports = [config, serverConfig];

例如：我从服务器端.style__header__1H9xAC9获得了html，在bundle.css中获得了.style__header__2uiLmVi但是如果我启用了JavaScript，应用程序在客户端再次使用bundle.css包含的相同className进行渲染。

在努力解决这个问题后，我发现我的错误在webpack.config，我在客户端使用context但在服务器中没有。所以我从客户端删除它，一切都很好。

const webpack = require('webpack');
const path = require('path');
const context = path.resolve(__dirname, 'src');

const config = {
    name:"client",
    context,
    entry: './App.js',
    output: {
        path: __dirname+"/.build/assets",
        filename: 'bundle.js'
    },

要

 const webpack = require('webpack');
 const path = require('path');

 const config = {
     name:"client",
//-----------xxx------------
     entry: './App.js',
     output: {
         path: __dirname+"/.build/assets",
         filename: 'bundle.js'
     },

谢谢你的注意：）

服务器端渲染：'css-loader / locals'生成不同的classNames然后bundle.css - webpack
