【中文标题】无法让 webpack require.ensure 分块方法与 react-router 一起使用并生成单独的捆绑文件【英文标题】：Can't get webpack require.ensure chunking method to work with react-router and generate separate bundle files 【发布时间】：2016-10-22 23:13:37 【问题描述】：我想使用 webpack 分块方法在我的路由配置中为单独的路由生成单独的包。 实现它的一种方法是使用 require.ensure 定义块的拆分点并根据浏览器的需求异步加载模块。
这是我得到的：
webpack.config.js（根据执行的 npm 脚本与 dev/prod webpack 配置合并）：
var autoprefixer = require('autoprefixer');
var html = require('html-webpack-plugin');
var path = require('path');
var webpack = require('webpack');
var node_modules_dir = path.resolve('./node_modules')
var HappyPack = require('happypack');
module.exports =
context: path.resolve('./src'),
entry:
app: ['./scripts/index.js', './styles/index.scss'],
vendor: ['react', 'react-dom', 'react-redux', 'redux','immutable'],
,
module:
loaders: [
test: /\.(jpg|png|gif|json)$/,
loader: 'file',
query:
name: 'assets/[hash].[ext]',
,
,
test: /\.svg$/,
loader: 'happypack/loader?id=svg'
,
],
,
output:
filename: '[name].js',
path: path.resolve('./build'),
,
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
// new webpack.optimize.LimitChunkCountPlugin(maxChunks: 5),
// new webpack.optimize.MinChunkSizePlugin(minChunkSize: 10000),
new html(
minify:
collapseWhitespace: true,
,
template: './index.html',
title: process.env.npm_package_config_title,
),
new webpack.optimize.CommonsChunkPlugin('vendor','vendor.bundle.js'),
new HappyPack(
id: 'svg',
threads: 5,
loaders: [
'svg-inline'
]
)
],
postcss: function()
return [
autoprefixer,
];
,
resolve:
alias:
assets: path.resolve('./src/assets'),
lib: path.resolve('./src/lib'),
modules: path.resolve('./src/scripts/modules'),
scripts: path.resolve('./src/scripts'),
styles: path.resolve('./src/styles'),
toolbox: path.resolve('./node_modules/react-toolbox'),
vendors: path.resolve('./src/vendors'),
'react-redux': node_modules_dir + '/react-redux/dist/react-redux.min.js',
'redux': node_modules_dir + '/redux/dist/redux.min.js',
'immutable': node_modules_dir +'/immutable/dist/immutable.min.js'
,
extensions: [
'',
'.js',
'.jsx',
'.css',
'.scss',
],
,
toolbox:
theme: path.resolve('./toolbox/index.scss'),
,
;
webpack.config.dev.js（dev webpack配置[与上面合并]）：
var merge = require('webpack-merge');
var webpack = require('webpack');
var path = require('path');
var config = require('./config');
var HappyPack = require('happypack');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = merge(config,
// devtool: 'eval',
devServer:

historyApiFallback: true,
hot: true,

inline: true,
port: parseInt(process.env.npm_package_config_port),

test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'happypack/loader?id=jsx'
,
test: /\.s?css$/,
loader: 'happypack/loader?id=css'
,
],
,

routes.jsx：
[some module imports here]
export default (
<Route component= PermisionProvider >
<Route component= AppProvider >
<Route component= SnackbarProvider >
<Redirect from= paths.root to= localStorage.get('user') ? paths.login : paths.landingPageCities />
/* Landing */
<Route onEnter= _hasPermission.bind(null, 'landingPage') >
<Route component= LandingLayout >
<Route
path= paths.landingPageCities
getComponent=(location, callback) =>
require.ensure(['modules/landing_page/smarts/SmartLandingCities'], function (require)
callback(null, require('modules/landing_page/smarts/SmartLandingCities').default);
, 'SmartLandingCities');
/>
<Route
path= paths.landingPageCompanies
getComponent=(location, callback) =>
require.ensure(['modules/landing_page/smarts/SmartLandingCompanies'], function (require)
callback(null, require('modules/landing_page/smarts/SmartLandingCompanies').default);
, 'SmartLandingCompanies');
/>
<Route
path= paths.aboutUsPage
getComponent=(location, callback) =>
require.ensure(['modules/landing_page/views/AboutUsPage'], function (require)
callback(null, require('modules/landing_page/views/AboutUsPage').default);
, 'AboutUsPage');
/>
</Route>
</Route>
/* Login */
<Route onEnter= _hasPermission.bind(null, 'login') >
我阅读了大量的博客文章和教程，这一切似乎都在这里。然而，webpack 并没有为我使用 require.ensure 的两个路由生成单独的包：
SmartLandingCities SmartLandingCompanies 关于我们页面我已经非常绝望了，因为应用程序包的大小为 2mb，而且我已经使用了所有可用的大小缩小方法。
感谢您的帮助！
【问题讨论】：
Using webpack and react-router for lazyloading and code-splitting not loading的可能重复 @azrahel，我也遇到了同样的问题，也发布了一个问题***.com/questions/39757297。虽然查看您的 webpack.config 文件，但您没有定义 chunkFilename: "[name].js" 而在 dev config 中您定义了。尝试在生产配置中添加它。如果你已经解决了，请告诉我。 嘿，是的，已经解决了。我真的不记得确切的问题是什么，但我可以向您发送我最近开始的小项目，上面的代码正常工作。 那太棒了。如果它在 github 上，你能发布项目的链接吗？ @azrahel 如果您有其他喜欢的方法，请告诉我。 【参考方案1】：由于已经有三个请求访问包含工作解决方案的 repo，所以这里是:) 祝您编码愉快！
